What is Nerve Innervation?

Anatomically, it refers to the distribution of peripheral nerves in specific parts or organs of the animal body, which means that such organs are innervated. In terms of anatomy alone, the term nerve distribution can also be used.

Innervation innervation

The inner organ is called the terminal organ of the nerve. Innervation can be roughly divided into efferent and afferent. The former has motor nerves that innervate muscles and secretory nerves that innervate glands, and the latter is sensory nerves that pass from the receptor to the center. Among the nerves that govern vertebrate skeletal muscles, in addition to motor nerves, there are also tension nerves that govern muscle tension and muscle tension, and nutritional nerves that govern muscle nutrition. However, there are still different opinions on whether they do exist. Crustacean diaphragm muscles and bivalve occluder muscles are dominated by motor nerves that contract muscles and nerves that suppress muscle contractions. The visceral muscles and myocardium of higher animals are mutually dominated by the nerves that promote their activity and the nerves that inhibit their activity (both autonomic nerves). By this balancing effect, the muscles can maintain a certain degree of tension or maintain an appropriate pulse. frequency. Dominant forms such as these are called double innervations. The pupil muscles and the like are slightly different from the above. The pupil dilation muscle is innervated by the sympathetic nerve, the pupil sphincter is innervated by the parasympathetic nerve, and the diaphragm of the two muscles increases or decreases the pupil diameter.
