muscle
Sign in to saveMuscle is a specialised soft tissue, one of the four basic types of animal tissues. There are three types of muscle tissues in vertebrates:- skeletal muscle tissue, cardiac muscle tissue, and smooth muscle tissue. Muscle tissue gives skeletal muscles the ability to contract and relax. Muscle tissue contains special contractile proteins called actin and myosin which interact to cause movement. Among many other muscle proteins present are two regulatory proteins, troponin and tropomyosin. Muscle is formed during embryonic development, in a process known as myogenesis.
AI overview
Muscle is a specialized soft tissue that contains special proteins (actin and myosin) which allow it to contract and relax, enabling movement in the body. There are three types of muscle tissue in vertebrates—skeletal, cardiac, and smooth—each playing important roles in how animals function.

Muscle is a specialised soft tissue, one of the four basic types of animal tissues. There are three types of muscle tissues in vertebrates:- skeletal muscle tissue, cardiac muscle tissue, and smooth muscle tissue. Muscle tissue gives skeletal muscles the ability to contract and relax. Muscle tissue contains special contractile proteins called actin and myosin which interact to cause movement. Among many other muscle proteins present are two regulatory proteins, troponin and tropomyosin. Muscle is formed during embryonic development, in a process known as myogenesis.
Skeletal muscle tissue is striated, consisting of elongated, multinucleate muscle cells called muscle fibers, and is responsible for movements of the body. Other tissues in skeletal muscle include tendons and perimysium. Smooth and cardiac muscle contract involuntarily, without conscious intervention. These muscle types may be activated both through the interaction of the central nervous system as well as by innervation from peripheral plexus or endocrine (hormonal) activation. Skeletal muscle only contracts voluntarily, under the influence of the central nervous system. Reflexes are a form of non-conscious activation of skeletal muscles, but nonetheless arise through activation of the central nervous system, albeit not engaging cortical structures until after the contraction has occurred.
