NEET PG DENTAL EXAM

Detailed explanation-1: -The motor (efferent) division carries motor signals by way of efferent nerve fibers from the CNS to effectors (mainly glands and muscles). It can be further subdivided into somatic and visceral divisions. The somatic motor division carries signals to the skeletal muscles.

Detailed explanation-2: -Therefore, spinal nerves are mixed nerves, carrying both afferent fibers and efferent fibers.

Detailed explanation-3: -The efferent fiber is a long process projecting far from the neuron’s body that carries nerve impulses away from the central nervous system toward the peripheral effector organs (mainly muscles and glands). A bundle of these fibers is called an efferent nerve (if it connects to muscles, then it is a motor nerve).

Detailed explanation-4: -The motor neuron carries efferent impulses to the effector, which produces the response.
