NEET BIOLOGY

Detailed explanation-1: -Motor neurons of the spinal cord are part of the central nervous system (CNS) and connect to muscles, glands and organs throughout the body. 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-2: -Cranial nerves and spinal nerves extend from the CNS to peripheral organs such as muscles and glands.

Detailed explanation-3: -Sensory neurons typically have a long dendrite and short axon, and carry messages from sensory receptors to the central nervous system. Motor neurons have a long axon and short dendrites and transmit messages from the central nervous system to the muscles (or to glands).

Detailed explanation-4: -Neurons carry messages from the brain via the spinal cord. The neurons that carry these messages to the muscles are called motor neurons. Each motor neuron ending sits very close to a muscle fibre.

Detailed explanation-5: -Efferent neurons-these take messages from the central nervous system (brain and spinal cord) and deliver them to cells in other parts of the body. Afferent neurons-take messages from the rest of the body and deliver them to the central nervous system (CNS).
