Question

the nervous system is divided into the CNS and the PNS. the PNS is divided into the 3. The nervous system is divided into the CNS and the PNS. The PNS is divided into the and the divisions. The division is further divided into somatic and autonomic portions. The autonomic nervous system innervates and whereas the somatic nervous system innervates 4. Is a nerve an organ or a tissue? Explain. 5. List the three categories of neurons based on structure: 6. List the three categories of neurons based on function:

Explanation / Answer

The PNS is divided into somatic nervous system and the autonomic nervous system divisions.The peripheral nervous system is divided into somatic and autonomic divisions.The autonomic nervous system divided into sympathetic and parasympathetic nervous system the somatic nervous system is divided into sensory nervous system and stomato sensory system.

A nerve ia an enclosed cable like bundles of axons in the peripheral nervous system.A nerve provides a common pathway for the electrochemical nerve impulses that are transmitted along the each axons to peripheral axons.With in a nerve each axon is surrounded by a layer of connective tissue hence nerve is a tissue.

The three catogories of neurons based on structure are 1) Bipolar 2) Unipolar 3) Multipolar

The three catogories of neurons based on function 1)sensory neurons 2)Interneurons or associative neurons 3) Motor neurons
