What is Dense Connective Tissue?
All connective tissues contain specialized cells, extracellular protein fibers, and ground substance. The protein fibers and ground substance surround specialized cells in connective tissues and form what is called the matrix. The matrix is the most voluminous component of all connective tissues.
What is the structure that connects bones to muscles?
Tendons are cordlike structures of dense regular connective tissues that affix skeletal muscles to bones. The collagen fibers in tendons are orientated length-wise in the direction of the force that muscle contraction places on a bone.
What is dense collagen?
Dense collagen connective tissue is more common and primarily consists of thick collagen fibers. This tissue is strong and resistant to tearing along its longitudinal axis. This tissue type can be referred to as white connective tissue, due to the white appearance of collagen, and is found in tendons, ligaments, and aponeuroses.
What is collagen fiber?
Collagen fibers are long, wavy, non-branching fiber bundles. Visible fibers are made up of many protein subunits that are tightly wound together, they are white in color, but will appear thick and light in color on most histological slides and diagrams. Collagen fibers are the most abundant fibers in connective tissue proper and provide strength and rigidity.
What are the components of dense regular connective tissue?
The identifiable components of dense regular connective tissues are fibroblasts and protein fibers. Because of the dense, regular arrangement of the fibers, the ground substance is rarely visible on histological slides and diagrams. There are far more fibers than fibroblasts present in dense regular connective tissue. Below are the components of this tissue type.
What type of tissue is dense and tightly packed?
Protein fibers in dense regular connective tissue run in tightly packed, parallel bundles. Fibers are often wavy in appearance. The specialized cells in this tissue type are called fibroblasts. They are often more darkly stained in histological slides and diagrams, they are scattered in between the parallel fibers.

The photo on the right shows the woven appearance of dense irregular connective tissue, this histological photo shows areolar tissue at magnification 400x.
What is Fibrous Tissue?
Polysaccharides are the other component of fibrous connective tissue that helps it to be a supportive tissue. Fibrous connective tissue is strong and stretchy which allows for support and strengthening of the bones and organs of the body. The fibrous connective tissue acts very similarly to how shocks act in a car. It helps to absorb the shock of movement which helps to protect the organs and tissues of the body. Without fibrous connective tissue, the organs of the body would get damaged whenever they move to function.
What connects muscles to each other?
The fasciae are the fibrous connective tissues that connect the muscles in the body to other muscles in the body. They also separate, stabilize and enclose muscles in the body. The blood vessels and nerves that supply the muscles are usually also contained in the fasciae. Fasciae allow the muscles to move as they contract but prevent them from moving too far apart from each other. There are areas of the body where there are large muscle groups that need to be connected to each other. The back is one of those areas. There are multiple muscles in the back area and they are all connected to each other through fasciae.
What are the tendons in the body?
Tendons are the fibrous connective tissue that connects the muscles of the body to the bones of the body. Tendons are organized into a cord-like structure. The tendons allow the muscles to move the bones of the body by moving bones when the muscles contract. While they permit the muscles to move the bones, they are not stretchy. Tendons are not easy to tear, but since they are not stretchy they tend to get damaged rather easily. The largest and strongest tendon in the body is the Achilles tendon which is located at the back of the heel and connects the muscle of the calf to the bone of the heel of the foot. The Achilles tendon moves the heel when the muscles in the calf contract. The shoulder is another location where there are several tendons. The rotator cuff is made up of multiple tendons, muscles, and bones.
How many types of fibrous connective tissue are there?
There are three different types of fibrous connective tissue in the body. Each one has a different function in the body. The different fibrous connective tissue types are explained below.
What are the ligaments that hold the bones together?
Every joint in the body has ligaments that hold them together. The ankles have three main ligaments that hold them together. The calcaneofibular ligament is the ligament in the ankle that connects the small bone of the lower leg to the heel bone. The other two ligaments are the anterior talofibular ligament and the posterior talofibular ligament. They connect the bone that is located between the shin and heel to the small bone in the lower leg.
What are the two types of fasciae?
There are two main types of fasciae found in the body. The first is deep fasciae which are the fasciae that go around and through the muscles, blood vessels, bone, and nerves of the body. The other type of fasciae is the visceral fasciae, also called parietal fasciae . These are the ones that are located at the site of the internal organs and function to anchor the organs in the different body cavities and surround them in a thin layer of connective tissue.
What are the different types of tissues?
There are four different types of tissues in the body. They are epithelial, nervous, muscular, and connective tissue. Connective tissue is the tissue that supports other tissues in the body by protecting and giving structure to the tissues. It also helps to anchor down and support the organs of the body. Connective tissue has the function of helping to prevent damage to the organs of the body as the organs move while they function. The connective tissue includes fat, dermis, cartilage, bone, and blood.
What is dense connective tissue?
Anatomical terms of microanatomy. Dense connective tissue, also called dense fibrous tissue, is a type of connective tissue with fibers as its main matrix element. The fibers are mainly composed of type I collagen. Crowded between the collagen fibers are rows of fibroblasts, fiber-forming cells, that generate the fibers.
Which type of connective tissue attaches skeletal muscles to bones?
Tendons attach skeletal muscles to bones; ligaments connect bones to bones at joints. Ligaments are more stretchy and contain more elastic fibers than tendons. Dense connective tissue also make up the lower layers of the skin (dermis), where it is arranged in sheets.

What is the ground substance in connective tissue?
The ground substance acts as a fluid matrix that suspends the cells and fibers within the particular connective tissue type. Connective tissue fibers and matrix are synthesized by specialized cells called fibroblasts. There are three main groups of connective tissues: loose connective tissue, dense connective tissue, and specialized connective tissue.
Why is spongy bone called cancellous bone?
Spongy bone, also called cancellous bone, gets its name because of its spongy appearance. The large spaces, or vascular cavities, in this type of bone tissue contain blood vessels and bone marrow. Spongy bone is the first bone type formed during bone formation and is surrounded by compact bone.
Why is loose connective tissue called loose connective tissue?
Loose connective tissue is named so because of the "weave" and type of its constituent fibers. These fibers form an irregular network with spaces between the fibers. The spaces are filled with ground substance. The three main types of loose connective fibers include collagenous, elastic, and reticular fibers.
What is the insulating layer of fat tissue?

What is the function of connective tissue?
As the name implies, connective tissue serves a connecting function: It supports and binds other tissues in the body. Unlike epithelial tissue, which has cells that are closely packed together, connective tissue typically has cells scattered throughout an extracellular matrix of fibrous proteins and glycoproteins attached to a basement membrane. The primary elements of connective tissue include a ground substance, fibers, and cells.
What are the three types of loose fibers?
The three main types of loose connective fibers include collagenous, elastic, and reticular fiber s. Collagenous fibers are made of collagen and consist of bundles of fibrils that are coils of collagen molecules. These fibers help to strengthen connective tissue. Elastic fibers are made of the protein elastin and are stretchable.
What is the difference between irregular and dense tissue?
The main difference is the arrangement of connective tissue fibers; in irregular tissue, you will find the randomly oriented fibers bundles. Whereas fibers are oriented inconsistent patterns in dense regular tissue structure.
What are the irregular arrangements of collagen fibers?
The irregular arrangements of collagen fibers of dense irregular tissue allow adaptation to changes in the size of the organs or diameter of the muscles of animal’s body.
What will you learn about dense irregular tissue?
You will learn the fibers’ orientation (especially the collagen and elastic fibers) and cells from the dense irregular tissue. You will get the identification points that might help you identify the histology slide of dense irregular tissue samples under a light microscope.
What is dense connective tissue?
Dense connective tissue is white that has less flexibility and far more resistant to stress. You know, dense connective tissue divides into dense regular connective tissue and dense irregular connective tissue based on fibers orientation.
Why is the stretching force withstood in any direction?
Again, the stretching force could be withstood in any direction due to irregular arrangements of collagen fibers. You will also find numerous elastic fibers in the dense irregular tissue structure. These elastic fibers are also larger, multiple, branching, and anastomosing with each other.
What are the cells in dense tissue?
The cells are mainly fibroblasts in dense regular tissue, whereas you will find fibrocytes and other connective tissue cells in the dense irregular tissue. But both dense tissues have a small amount of ground substances.
Where is elastic connective tissue found?
It may found in the place where the elasticity requires like in ligamentum nuchae.
Are dense breasts a risk factor for breast cancer?
Yes, women with dense breasts have a higher risk of breast cancer than women with fatty breasts, and the risk increases with increasing breast density. This increased risk is separate from the effect of dense breasts on the ability to read a mammogram.
Are breast cancer patients with dense breasts more likely to die from breast cancer?
No. Research has found that breast cancer patients who have dense breasts are no more likely to die from breast cancer than breast cancer patients who have fatty breasts, after accounting for other health factors and tumor characteristics.
What are dense breasts?
Dense breasts have relatively high amounts of glandular tissue and fibrous connective tissue and relatively low amounts of fatty breast tissue.
How do I know if I have dense breasts?
Only a mammogram can show if a woman has dense breasts. Dense breast tissue cannot be felt in a clinical breast exam or in a breast self-exam. For this reason, dense breasts are sometimes referred to as mammographically dense breasts.
What is the name of the system used by doctors to report back mammograms?
Doctors use the Breast Imaging Reporting and Data System, called BI-RADS, to group different types of breast density. This system, developed by the American College of Radiology. , helps doctors to interpret and report back mammogram findings. Doctors who review mammograms are called radiologists.
Does dense breast tissue affect mammograms?
Does having dense breast tissue affect a woman’s mammogram? Mammograms can be harder to read in women with dense breasts than in women with fatty breasts. That's because dense breast tissue and some abnormal breast changes, such as calcifications and tumors , appear as white areas in the mammogram.
Can breast cancer be detected after a mammogram?
Recent research has suggested that for women with dense breasts, a screening strategy that also takes into account a woman’s risk factors and protective factors may be the best predictor of whether a woman will develop breast cancer after a normal mammogram and before her next scheduled mammogram.
What is dense fibrous tissue?
Dense connective tissue, is one of the types of connective tissue also referred to as dense fibrous tissue due to relative abundance of the collagen fibers. It also contains fewer cells and less ground substance in comparison with the other type, loose connective tissue . Dense connective tissue is often further divided into two main categories; dense irregular connective tissue and dense regular connective tissue.
What is the role of dense regular connective tissue?
Tendons and ligaments attach to bones, and the role of dense regular connective tissue is to transfer forces to bones. A small amount of ground substance is present around dense regular connective tissue fibers and cells. Dense regular collagenous connective tissue (histological slide)
What type of connective tissue is surrounded by small amounts of ground substance?
Dense irregular connective tissue. The type I collagen fibers of the dense irregular connective tissue are surrounded by small amounts of ground substance. Among the collagen fibers there is a network of elastic fibers as well, to limit the distensibility of the tissue. Ground substance is amorphous and gel-like in texture that surrounds cells.

Dense connective tissue, is one of the types of connective tissue also referred to as dense fibrous tissue due to relative abundance of the collagen fibers.
Why is dense irregular connective tissue found in high concentrations in body parts?
Dense irregular connective tissue is found in high concentrations in body parts where support is needed to prevent the effects of forces that pull in multiple directions. Its 3-dimensional structure allows it to withstand force from different directions.
How do ligaments form?
Ligaments form from thick bundles of connective tissue, mainly forming from collagen. Despite their density, ligaments can still be fairly elastic. Ligaments need to be strong as they connect bones together, and hold joints in place.
