Muscle Tissues are made up of cells that are specifically designed to contract. To elaborate, Muscle tissues are made up of cells with the unique capacity to shorten or contract in order to cause bodily components to move. The tissue is densely packed with cells and has a good supply of blood vessels. Because the cells are long and slender, they are sometimes referred to as muscle fibers, and they are typically grouped in bundles or layers surrounded by connective tissue. Muscle tissue contains contractile proteins such as actin and myosin.
Muscle is classified into three types according to their structure and function:
Skeletal Muscle Tissue – striated, voluntary control. The skeletal movements are controlled by this type of muscle, which is linked to the bone. The skeletal muscles are controlled by the peripheral component of the central nervous system (CNS). These muscles can be controlled voluntarily or consciously. The muscle fiber, which has numerous nuclei, is the fundamental unit. These muscle fibers are striated (meaning they have transverse streaks) and function independently of one another. Movement, heat production, and posture are the three main functions of skeletal muscle.
Cardiac Muscle Tissue – striated, involuntary control. The autonomic nervous system also controls the type of muscle found in the heart’s walls. Like smooth muscle, the cardiac muscle has a single central nucleus, but it is also striated like skeletal muscle. The heart muscle cell is shaped like a rectangle. Cardiac muscle contractions are involuntary, powerful, and regular.
Smooth Muscle Tissue – nonstriated, involuntary control.The autonomic nervous system regulates the type of muscle present in the walls of hollow internal organs such as blood vessels, the gastrointestinal tract, the bladder, and the uterus. Smooth muscle is incapable of cognitive control and hence operates spontaneously. The spindle-shaped nonstriated (smooth) muscle cell has one central nucleus. Smooth muscle contracts slowly and in a regular pattern.
