Detailed explanation-1: -The word innervate sounds like what it is-it means to “put the nerves into” something. When nerves go into muscle fiber, they innervate the muscle fiber. Innervate is to supply nerves to something, but it can also mean to energize. Think of all the energy you have when you get nervous!
Detailed explanation-2: -Innervated Muscles When nerves enter the muscle fibres, it innervates the fibres. To innervate is to supply nerves with something in addition to also energizing it. All nerve fibres that supply the muscles are intact.
Detailed explanation-3: -The muscles which have neuro-muscular spindles are innervated by nerves composed of extra-and intrafusal motor fibres and proprioceptive fibres. The neuro-muscular spindles play a servo-braking role in the muscle where they occur. They oppose then a certain passive elongation of the muscle.
Detailed explanation-4: -The posterior ramus innervates the muscles and joints of the spine and the skin of the back. The anterior ramus innervates the anterior and lateral skin and muscles of the trunk, plus gives rise to nerves leading to the limbs (see image below).
