AP BIOLOGY

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: -Afferent neurons in the dorsal roots carry impulses from the body’s sensory receptors to the spinal cord, where the information begins to be processed.

Detailed explanation-3: -Sensory Neurons carry incoming information from the sense receptors to the CNS. Motor Neurons carry outgoing information from the CNS to muscles and glands. Interneurons connect the two neurons.

Detailed explanation-4: -Motor neurons transmit nerve impulses from the brain and spinal cord to a specific area of the body.

Detailed explanation-5: -Answer and Explanation: An upper motor neuron carries motor information down the spinal cord from an area in the brain. Upper motor neurons can also travel from the brain to the brainstem.
