Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Neurons that convey information to the CNS are called sensory, or ____ neurons.
A
Afferent
B
Efferent
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -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-2: -Functional types Afferent (sensory) neurons – carry information towards the CNS for processing; Interneurons (association neurons) – multipolar neurons located extensively in the brain and spinal cord (CNS).

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: -To accurately respond to stimuli, the brain relies on information communicated by sensory neurons. Sensory neurons detect inputs from the environment, convert them into signals (electrical impulses), and pass the information on to the brain and spinal cord, where a response can be generated.

Detailed explanation-5: -Sensory neurons, also known as afferent neurons, are neurons in the nervous system, that convert a specific type of stimulus, via their receptors, into action potentials or graded potentials. This process is called sensory transduction.
