Pns Anatomy

The peripheral nerves include the 12 cranial nerves the spinal nerves and roots and what are called the autonomic nerves. The sympathetic nervous system is the fight or flight system which comes into role when an animal is under threat its main neurotransmitter is adrenaline.

Overview Of Pns Spinal Nerves Guo Ling Md Phd Department

The autonomic nerves are concerned with automatic functions of the body.

Pns anatomy. The autonomic nervous system is then split into the sympathetic nervous system parasympathetic nervous system and enteric division. Structures of the pns. Home biology anatomy and physiology.

The peripheral nervous system is a channel for the relay of sensory and motor impulses between the central nervous system on one hand and the body surface skeletal muscles and internal organs on the other hand. The nerves in the peripheral nervous system pns connect the central nervous system cns to sensory organs such as the eye and ear other organs of the body muscles blood vessels and glands. The autonomic nervous system is the part of the nervous system concerned with the innervation of involuntary structures such as the heart smooth muscle and glands within the body.

Peripheral nervous system overview. The peripheral nervous system pns includes all neural tissue excluding the brain and the spinal cord. The pns allows the cns to communicate with the external environment.

Here ganglia and nerves will be the focus of discussion. The pns consists of all nervous tissue outside of the brain and spinal cord. The peripheral nervous system.

It includes the ganglia nerves and receptors as they are found in various parts of the body. In the peripheral nervous system bundles of nerve ﬁbers or axons conduct information to and from the central nervous system. The pns is the communication network between the cns and the rest of the body.
