What is muscle tissue made of?
Muscle tissue is formed during embryonic development, in a process known as myogenesis. Muscle tissue contains special contractile proteins called actin and myosin which contract and relax to cause movement. Among many other muscle proteins present are two regulatory proteins, troponin and tropomyosin.

What is the function of muscle tissue?
Function of Muscle Tissue. Muscle tissue functions as a single unit, and is often connected to the same nerve bundles. A nerve impulse traveling from the brain or another outside signal tells the muscle to contract. The nerve impulse is transferred almost instantaneously to all the nerve cells in the muscle tissue, and the entire muscle contracts.
What is muscle tissue?
Muscle tissue consists of fibers of muscle cells connected together in sheets and fibers. Together these sheets and fibers and known as muscles, and control the movements of an organisms as well as many other contractile functions. There are three different types of muscle found in animals, depending on their use.
Why does muscle feel hard when flexed?
They are necessary for supporting the body and organs. Muscle only seems hard when flexed because the cells are being packed much closer together. The pressure on the cells and the tension in the fibers create the sense that the tissue is rigid, but it is not. 3. Dr.
Why do plants use myosin?
For instance, plants use actin and myosin as a way to create a current in their cytoplasm and circulate nutrients. Other animal cells use actin and myosin to transport materials inside the cell. A test for actin and myosin would quickly show it is present in far more than muscle tissue.

Contraction of skeletal muscle produces voluntary gross and fine movements, a primary function of the muscular system. Gross movements rely primarily on large skeletal muscles.
Why are axial skeletal muscles important?
The axial skeletal muscles are particularly important for maintaining an upright position, and enabling you to twist your head and body. In conjunction with the rib and spinal bones of your trunk, the axial skeletal muscles also provide protection for your internal organs. For example, your rectus abdominus, transverse abdominus ...
What muscles are involved in fine motor skills?
Fine motor skills typically involve small skeletal muscles of your hands, face or feet. Although most skeletal muscles are under voluntary control, they can also contract reflexively -- such as blinking when an insect flies toward your face or pulling your hand away from a hot surface.
How do smooth muscle cells contribute to blood circulation?
Smooth muscle cells in the walls of your arteries and veins also contribute to blood circulation by altering the diameter of these blood vessels in different situations.

What is the specialized tissue in animals that applies forces to different parts of the body by contraction?
Muscular tissue is a specialized tissue in animals which applies forces to different parts of the body by contraction. It is made up of thin and elongated cells called muscle fibers. It controls the movement of an organism. The cytoplasm in the muscle fibers is called sarcoplasm. It contains a network of membrane called the sarcoplasmic reticulum.
What are the light and dark bands in the skeletal muscle?
These light and dark bands are sarcomeres which are highly organized structures of actin, myosin, and proteins. These add to the contractility and extensibility of the muscles. Skeletal muscles are voluntary muscles composed of muscle fibers. 40% of our body mass comprises skeletal muscles. Each skeletal tissue contains myofibrils.

The muscular tissue is of three types:
What type of tissue is found only in the heart?
Cardiac Muscle Tissue. These are found only in the heart. These are involuntary muscles and the heart pumps the blood through cardiac contractions. The cells of the cardiac muscles known as the cardiomyocytes are striated. They are single-celled and uninucleated.

Muscle tissue is made up of excitable cells, capable of exerting a contraction and relaxation movement. It is the most abundant tissue among all the different types of tissues that are present in the human body, such as the epithelial, connective and nervous.
What is the shape of the cardiac muscle fiber?
The fibers of the cardiac muscle tissue are striated and branched, sometimes characterized by having a"Y"shape and a single central nucleus. These fibers are attached at their ends to adjacent fibers by means of thick plasma membranes called intercalated discs which are the ones that allow a synchronization when the heart beats.
What is striated muscle tissue?
Skeletal tissue is known as striated muscle tissue because of its appearance. Unlike heart tissue, this tissue is composed of light and dark bands visible only through a microscope and is not branched.
What type of tissue is cylindrical?
Similarly, skeletal tissu e cells are cylindrical in shape with many nuclei located at their edges or periphery. These cells are covered by connective tissue that protects clusters of muscle fibers.
What are the different types of muscle tissue?
There are three different types of muscle tissue: skeletal, cardiac and smooth tissue. These types of tissue are classified according to the level of detail of the muscle fibers that allow each different type of tissue to exert specific functions.
Why is skeletal muscle called skeletal muscle?
Skeletal muscle tissue is called this way, because it is attached to the bones by means of tendons. It is controlled by the peripheral nervous system And is associated with voluntary body movements (Bailey, 2016).

Skeletal Stability and Organ Protection
- Your bones provide the frame for your body. Your skeleton, however, lacks structural stability without the skeletal muscles and their associated tendons that hold your bones together and keep them in place. Even in a static posture, such as when you're standing still, numerous skeletal muscles of the trunk, neck and legs must remain in a contracted state to support your body and …
Blood Circulation
- Your heart is the hardest working muscle in your body, contracting at least 60 to 100 times per minute from cradle to grave. The wall of your heart consists of highly specialized cardiac muscle tissue, which contracts involuntarily in response to electrical signals generated within the heart. With each contraction of your heart, blood is pumped through your circulatory system. This esse…
Internal Organ Function
- Several internal organs contain smooth muscle tissue, which contracts automatically to support their normal function. For example, smooth muscle tissue in the walls of your esophagus, stomach, and small and large intestines produce rhythmic contractions that propel food through your digestive tract. Similarly, smooth muscle in the wall of your blad...
Body Temperature Regulation
- A normal body temperature of roughly 98.6 F is generally lower than the environmental temperature. Since body heat is lost to the environment in typical conditions, your body must generate heat to maintain a normal temperature. Most of this needed heat is generated by your skeletal muscles. When your body temperature decreases, skeletal muscle activity automaticall…
