Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
If I step on a nail, what type of neurons take the response from the CNS TO an effector?
A
motor neurons
B
interneurons
C
sensory neurons
D
not neurons, muscle tissue sends the response
Explanation: 

Detailed explanation-1: -Sensory neurons carry impulses from the receptors in the sense organs to the CNS, while the association or connection neurons carry impulses from the sensory to the motor neurons. The motor neurons carry impulses from the CNS to the effectors.

Detailed explanation-2: -Afferent neurons carry information from sensory receptors found all over the body towards the central nervous system, whereas efferent neurons carry motor information away from the central nervous system to the muscles and glands of the body in order to initiate an action.

Detailed explanation-3: -Afferent or sensory neurons collect stimuli received by receptors throughout the body, including the skin, eyes, ears, nose, tongue as well as pain and other receptors in the internal organs. Sensory information is transmitted to the central nervous system, which includes the brain and spinal cord.

Detailed explanation-4: -Afferent neurons are sensory neurons that carry nerve impulses from sensory stimuli towards the central nervous system and brain, while efferent neurons are motor neurons that carry neural impulses away from the central nervous systme and towards muscles to cause movement.
