Tissue types
- Epithelial tissue creates protective boundaries and is involved in the diffusion of ions and molecules.
- Connective tissue underlies and supports other tissue types.
- Muscle tissue contracts to initiate movement in the body.
- Nervous tissue transmits and integrates information through the central and peripheral nervous systems.
What are the four most common types of tissue?
There are two main types of primary lung cancer (beginning in the lungs), non-small-cell lung cancer (the most common), of which there are three types, and small-cell lung cancer (less common). Lung cancer most commonly affects older people, with more than four out of 10 diagnosed in the UK aged 75 and over.

How are tissues of the body classified?
The human body consists of four types of tissue: epithelial, connective, muscular, and nervous. Epithelial tissue covers the body, lines all cavities, and composes the glands. Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. Epithelial layers are avascular, but innervated.

Why do we classify tissues?
Classification is needed for convenient study of living organisms. It is necessary for knowing the different varieties of organisms. It helps in the correct identification of various organisms. It helps to know the origin and evolution of organisms.
What are 7 levels of classification?
His major groupings in the hierarchy of groups were, the kingdom, phylum, class, order, family, genus, and species; seven levels of groups within groups. This was arbitrary, and more levels have been added over the years since the time of Linnaeus.
What are the types of classification in biology?
The three types of classification are artificial classification, natural classification and phylogenetic classification.

What are the two types of tissue membranes?
Figure 4.1.3 – Tissue Membranes: The two broad categories of tissue membranes in the body are (1) connective tissue membranes, which include synovial membranes, and (2) epithelial membranes, which include mucous membranes, serous membranes, and the cutaneous membrane, in other words, the skin.
What is the epithelial membrane?
An epithelial membrane is composed of an epithelial layer attached to a layer of connective tissue. A mucous membrane, sometimes called a mucosa, lines a body cavity or hollow passageway that is open to the external environment. This type of membrane can be found lining portions of the digestive, respiratory, excretory, and reproductive tracts. Mucus, produced by uniglandular cells and glandular tissue, coats the epithelial layer. The underlying connective tissue, called the lamina propria (literally “own layer”), helps support the epithelial layer.
What is the membrane of a connective tissue?
When lining a joint, this membrane is referred to as a synovial membrane .
What is the membrane of the body?
A tissue membrane is a thin layer or sheet of cells that either covers the outside of the body ( e.g., skin), lines an internal body cavity ( e.g ., peritoneal cavity), lines a vessel (e.g., blood vessel), or lines a movable joint cavity (e.g., synovial joint). Two basic types of tissue membranes are recognized based on the primary tissue type composing each: connective tissue membranes and epithelial membranes ( Figure 4.1.3 ).
What is the layer of the body that is covered by mucus?
Mucus, produced by uniglandular cells and glandular tissue, coats the epithelial layer. The underlying connective tissue, called the lamina propria (literally “own layer”), helps support the epithelial layer. A serous membrane lines the cavities of the body that do not open to the external environment.
What is the name of the cell that forms the germ layer?
Each germ layer is identified by its relative position: ectoderm (ecto- = “outer”), mesoderm (meso- = “middle”), and endoderm (endo- = “inner”).
What is tissue in biology?
Tissue Definition. Tissues are groups of cells that have a similar structure and act together to perform a specific function. The word tissue comes from a form of an old French verb meaning “to weave”. There are four different types of tissues in animals: connective, muscle, nervous, and epithelial. In plants, tissues are divided ...
What are the three types of tissue found in plants?
Ground tissue, epidermal tissue, and vascular tissue are the three general types of tissues found in plants. Connective tissue is a type of animal tissue that connects or separates other tissues, and it also includes lymph and blood. 2.
What is ground tissue?
Ground tissue is made up of all cells that are not vascular or dermal (having to do with the epidermis; see below). There are three types of ground tissue: parenchyma, collenchyma, and sclerenchyma. Parenchyma cells form the “filler” tissue in plants, and perform many functions like photosynthesis, storage of starch, fats, oils, proteins, and water, and repairing damaged tissue. Collenchyma tissue is made up of long cells with irregularly thick walls that provide structural support to the plant. Plants that grow in windy areas have thicker walls of collenchyma tissue. Sclerenchyma is also supporting tissue, but it is made of dead cells. There are two types of sclerenchyma: fibers and sclereids. Fibers are long, slender cells, while sclereids are star-shaped with thick cell walls. Sclerenchyma fibers make up fabrics such as hemp and flax.
What is the difference between sclerenchyma and fibers?
There are two types of sclerenchyma: fibers and sclereids. Fibers are long, slender cells, while sclereids are star-shaped with thick cell walls.
What are the two types of vascular tissue?
The two types of vascular tissue are xylem and phloem. Xylem transports water and some soluble nutrients, while phloem transports organic compounds the plant uses as food, particularly sucrose. Vascular tissues are long and thin, and form cylinders that nutrients are transported through like pipes.
How many people have connective tissue disorders?
About 1 in 10 people are have a disorder involving connective tissue. Some connective tissue disorders include sarcomas, Marfan syndrome, lupus, and scurvy, which is a Vitamin C deficiency that leads to fragile connective tissue.
What is the epithelial tissue?
Epithelial tissue, or epithelium, covers the surfaces of organs including the skin, the trachea, the reproductive tract, and the digestive tract’s inner lining. It creates a barrier that helps protect organs, and it also has roles in absorbing water and nutrients, getting rid of waste, and secreting enzymes or hormones. All of the body’s glands are formed from ingrowths of epithelium. Some common epithelial tissue diseases are skin diseases like eczema and psoriasis, which both cause rashes. When cancer develops from epithelial tissue, it is called a carcinoma. Epithelial cells in the airways are also responsible for asthma, which is characterized by inflammation of the airways that leads to shortness of breath.
Definition of Connective Tissues
Connective tissues hold structures together, provide a framework and support for organs and the entire body, store fat, transport substances, defend against disease, and aid in tissue repair. Cells, fibres, and a gel-like material (ground substance) make up connective tissue. They can be found all over the body.
Origin of Connective Tissues
The most abundant and widely distributed tissue in the body is connective tissue. The embryo’s mesoderm is responsible for the formation of the connective tissues. It connects various tissues or organs and provides support to various structures of an animal body.
Components of Connective Tissues
The connective tissues contain three components. Matrix, cells, and fibres are the three components.
Types of Connective Tissues
The connective tissue supports the body and binds the body’s various tissues and organs together.
Functions of Connective Tissues
The connective tissue sheath that surrounds muscle cells, the tendons that connect muscles to bones, and the skeleton that maintains the body’s positions are all examples of attachment and support.
Connective Tissue Disorder
Gene mutations or inherited defective genes can cause connective tissue disorders. Epidermolysis bullosa (EB) and Marfan syndrome are two hereditary connective tissue disorders, and Rheumatoid arthritis & Scleroderma are autoimmune connective tissue disorders.
Summary
All tissues and organs in the body rely on this tissue for support, protection, and structure. Additionally, connective tissue stores fat, aids in the movement of nutrients and other substances between tissues and organs, and aids in the repair of injured tissue. Cells, fibres, and ground substances make up connective tissue.
