EVERYDAY SCIENCE

Detailed explanation-1: -The afferent division of the peripheral nervous system carries impulses to the CNS; the efferent division carries impulses away from the CNS. There are three layers of meninges around the brain and spinal cord.

Detailed explanation-2: -Efferent, or motor, neurons transmit impulses from the CNS to effector organs such as muscles and glands. Efferent neurons usually have short dendrites and long axons.

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: -Due to their function, nerve fibers which carry afferent impulses are known as afferent nerves or sensory nerves, and those nerve fibers which carry efferent impulses are known as efferent nerves or motor nerves.

Detailed explanation-5: -Motor, or efferent neurons transmit information away from the CNS toward some type of effector. Motor neurons are typically multipolar. Interneurons are located between motor and sensory pathways and are highly involved in signal integration.
