fibers that carry the signal from the spinal cord to the effector organ (muscle)
A
afferent
B
efferent
C
diencephalon
D
reflex
Explanation: 

Detailed explanation-1: -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-2: -Motor neurons carry signals from the brain and/or the spinal cord to the muscles and glands of the body.

Detailed explanation-3: -Afferent neurons carry information from sensory receptors of the skin and other organs to the central nervous system (i.e., brain and spinal cord), whereas efferent neurons carry motor information away from the central nervous system to the muscles and glands of the body.

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

Detailed explanation-5: -Efferent, or motor, nerve fibres carry impulses away from the central nervous system; afferent, or sensory, fibres carry impulses toward the central nervous system. Visceral fibres innervate the viscera such as the heart and intestines, and somatic fibres innervate the body-wall structures such as skin…
