AP BIOLOGY

Detailed explanation-1: -Sensory neurons carry nerve impulses from sense organs and internal organs to the central nervous system. Motor neurons carry nerve impulses from the central nervous system to organs, glands, and muscles-the opposite direction.

Detailed explanation-2: -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-3: -Your nervous system uses specialized cells called neurons to send signals, or messages, all over your body. These electrical signals travel between your brain, skin, organs, glands and muscles.

Detailed explanation-4: -Motor neurons These neurons transmit impulses from the spinal cord to skeletal and smooth muscles (such as those in your stomach), and so directly control all of our muscle movements.

Detailed explanation-5: -In a neuron or a nerve cell, the impulse travels through the axon towards the axonite. The dendrite of the receiving neuron picks up this impulse which is again transferred to another neuron or a cell. Hence, axon transfers the signal/impulse and the dendrite receives the impulse from other neurons.
