Muscular tissue is a type of tissue responsible for movement and contraction. It is responsible for the ability of organisms to perform various physical activities, such as walking, running, and lifting objects.
Muscular tissue is classified into two main types: smooth muscle and skeletal muscle. Smooth muscle is responsible for involuntary movements such as digestion and breathing. Skeletal muscle is responsible for voluntary movements, such as the muscles used during exercise.
Smooth Muscle
Smooth muscle is characterized by the presence of long, cylindrical fibers called cells. These cells are arranged in a random, unorganized manner, and they are responsible for the smooth, relaxed movements of the muscles during voluntary activities.
Examples of Smooth Muscle:
Skin
Heart wall
Lungs
Skeletal Muscle
Skeletal muscle is characterized by the presence of spindle-shaped fibers called myofibrils. These fibers are arranged in a parallel, organized manner, and they are responsible for the voluntary, powerful movements of the muscles during voluntary activities.
Examples of Skeletal Muscle:
Muscles of the body (e.g., skeletal, smooth, cardiac)
Smooth muscle in the walls of blood vessels and digestive tract
Cardiac muscle
