Question

An interneuron is defined as a neuron that:

A) Receives input from other neurons and projects in turn to other neurons.
B) Receives input from sensory receptors and projects in turn to other neurons.
C) Receives input from other neurons and projects in turn to muscles.
D) Is found only in the cerebral cortex.

Answer 1

An interneuron receives input from other neurons and projects to other neurons, acting as a connector primarily within the CNS. It is not primarily involved in receiving direct sensory input or projecting to muscles.

Step-by-step explanation:

An interneuron is a type of neuron that plays a critical role in the central nervous system (CNS). Its function is to carry nerve impulses between other types of neurons, particularly sensory neurons and motor neurons. Unlike motor neurons, which transmit impulses to muscles, or sensory neurons that receive signals from the body's sensory receptors, interneurons primarily serve as connectors or communicators within the brain and spinal cord. Therefore, the correct answer to the question 'An interneuron is defined as a neuron that:' is A) Receives input from other neurons and projects in turn to other neurons.
