text_B: Muscle tissue is a soft tissue that composes muscles in animal bodies , and gives rise to muscles ' ability to contract .. soft tissue. soft tissue. This is opposed to other components or tissues in muscle such as tendons or perimysium .. muscle. muscle. perimysium. perimysium. It is formed during embryonic development through a process known as myogenesis .. embryonic development. embryogenesis. myogenesis. myogenesis. Muscle tissue varies with function and location in the body .. In mammals the three types are  : skeletal or striated muscle ; smooth or non-striated muscle ; and cardiac muscle , which is sometimes known as semi-striated .. muscle. muscle. skeletal or striated muscle. Skeletal striated muscle. smooth. smooth muscle tissue. cardiac muscle. cardiac muscle. Smooth and cardiac muscle contracts involuntarily , without conscious intervention .. muscle. muscle. cardiac muscle. cardiac muscle. These muscle types may be activated both through interaction of the central nervous system as well as by receiving innervation from peripheral plexus or endocrine -LRB- hormonal -RRB- activation .. muscle. muscle. central nervous system. central nervous system. plexus. plexus ( neuroanatomy ). endocrine. endocrine system. Striated or skeletal muscle only contracts voluntarily , upon influence of the central nervous system .. muscle. muscle. central nervous system. 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 .. central nervous system. central nervous system. cortical. cerebral cortex. The different muscle types vary in their response to neurotransmitters and endocrine substances such as acetyl-choline , noradrenalin , adrenalin , nitric oxide and among others depending on muscle type and the exact location of the muscle .. muscle. muscle. endocrine. endocrine system. endocrine substances. hormone. acetyl-choline. acetyl-choline. noradrenalin. noradrenalin. adrenalin. adrenalin. nitric oxide. nitric oxide. Sub-categorization of muscle tissue is also possible , depending on among other things the content of myoglobin , mitochondria , myosin ATPase etc. .. muscle. muscle. myoglobin. myoglobin. mitochondria. mitochondria. myosin ATPase. myosin ATPase
