FORMATION OF SPINAL NERVES. POSTERIOR BRANCHES OF SPINAL NERVES.
Keywords:
Nerve, brain, spinal, blood, sensory, cord-nerve, nervous system.Abstract
Each nerve forms from nerve fibers, known as fila radicularia, extending from the posterior (dorsal) and anterior (ventral) roots of the spinal cord. The roots connect via interneurons. Grossly, the root fibers join together within the intervertebral foramina to form a spinal nerve. Spinal nerves are the nerves that start from the spinal cord in humans. Spinal nerves. 31 pairs: 8 pairs of neck, 12 pairs of chest, 5 pairs of back, 5 pairs of rump and 1 pair of caudal nerves. Spinal nerves. spreads to body muscles, skin. Spinal nerves. and the nerve fibers of the neck, shoulders, back, rump and tail formed in them connect the skin, internal organs and skeletal muscles of the whole body with the central nervous system (innervation). Spinal nerves. it contains sensory and motor fibers. Excitability receives sensations through nerve endings (receptors) located in organs, muscles, and skin to the central nervous system, and from there, through motor nerves, delivers the necessary response impulses to the working organs. The speed of transmission of effects is on average 0.5-120 m. It is faster in large-diameter nerves.[1]
