WebThe defining characteristic of the somatic nervous system is that it controls skeletal muscles. Somatic senses inform the nervous system about the external environment, but the response to that is through voluntary muscle movement. The term “voluntary” suggests that there is a conscious decision to make a movement. WebSep 27, 2024 · At its simplest, the neuromuscular junction is a type of synapse where neuronal signals from the brain or spinal cord interact with skeletal muscle fibers, causing them to contract. The activation of many muscle fibers together causes muscles to contract, which in turn can produce movement.

WebThe muscle action potential triggers a sequence of actions that ultimately results in the contraction and relaxation of the muscle fiber. This sequence is called the excitation–contraction–relaxation cycle. An early step in this cycle is the release of stored calcium from an intracellular membrane complex called the sarcoplasmic reticulum (SR).
