Unit 2.16 – Nerves Copy
Motor Nerves
The skin contains motor nerve endings that convey impulses from the brain, though the spinal cord to the muscles, glands and smooth muscular tissue.
Fibers
Nerves are cordlike structures carrying impulses from the periphery, muscles and joints to the brain and spinal cord. Messages pass along the nerve fibers as electrical impulses via a network of interlocking fibers surrounding the upper part of the follicle forming a collar. Fibers extend to the sebaceous glands, epidermis, arrector pili and sweat glands.
