Function of nucleus in skeletal muscle
Web- Nucleus are just under the plasmalemma (membrane surrounding the muscle fiber). - Muscle cells are striated (stripey). - Plasma membrane in a muscle cell is called a sarcolemma, and just under the sarcolemma, we have a nucleus. - Note: Satellite cells are on the outside of the sarcolemma membrane. WebThe red nucleus then sends corrective commands to the spinal cord along the rubrospinal tract. The name of this tract comes from the word for red that is seen in the English word “ruby.” A good example of how the cerebellum corrects cerebral motor commands can be illustrated by walking in water.
