what is the peripheral nervous system quizlet?

Peripheral nervous system (PNS) consists of nervous tissue found outside the brain and spinal cord, including nerves that exit the CNS and ganglia found throughout the body cavities.

The peripheral nervous system (PNS) is one of the two major divisions of the nervous system. ... 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 peripheral nervous system includes the cranial nerves (connected to brain innervate the head), spinal nerves (connected to spinal cord innervates the rest of the body), and ganglia (collections of neuron cell bodies in the PNS). You just studied 7 terms!

Divisions of the Peripheral Nervous System. The PNS is divided into two major systems, called the autonomic nervous system and the somatic (or sensory-somatic) nervous system. Both systems of the PNS interact with the CNS and include sensory and motor neurons, but they use different circuits of nerves and ganglia.

Summary. The peripheral nervous system (PNS) consists of the nerves and ganglia outside of the brain and spinal cord. There are four major types of glia in the PNS. They are myelinating and non‐myelinating Schwann cells, satellite glial cells (SGCs), enteric glial cells (EGCs), and olfactory ensheathing cells (OECs).

Peripheral Nervous System. The peripheral nervous system is divided into two major parts: the somatic nervous system and the autonomic nervous system.

The autonomic nervous system is a component of the peripheral nervous system that regulates involuntary physiologic processes including heart rate, blood pressure, respiration, digestion, and sexual arousal. It contains three anatomically distinct divisions: sympathetic, parasympathetic and enteric.

Structure. The peripheral nervous system is itself classified into two systems: the somatic nervous system and the autonomic nervous system. Each system contains afferent and efferent components. The afferent arm consists of sensory (or afferent) neurons running from receptors for stimuli to the CNS.

Nerves. Nerves are bundles of axons in the peripheral nervous system (PNS) that act as information highways to carry signals between the brain and spinal cord and the rest of the body. Each axon is wrapped in a connective tissue sheath called the endoneurium.

The peripheral nervous system (PNS) has two components: the somatic nervous system and the autonomic nervous system. The PNS consists of all of the nerves that lie outside the brain and spinal cord.

The peripheral nervous system includes all of the neurons that sense and communicate data to the central nervous system. The peripheral nervous system can be further divided into the autonomic system, which regulates involuntary actions, and the somatic system, which controls voluntary actions.

The nervous system can be divided into two major subdivisions: the central nervous system (CNS) and the peripheral nervous system (PNS), shown in [link]. The CNS is comprised of the brain and spinal cord; the PNS connects the CNS to the rest of the body.
740987
The brain and spinal cord make up the central nervous system. The peripheral nervous system is comprised of the somatic and autonomic nervous systems.

Answer: PNS serves as the relay between the central nervous system and the body. Explanation: The peripheral nervous system is a part or division of the nervous system of the animal which is comprised of all the neurons present outside the central nervous system.

The Central and Peripheral Nervous Systems We can anatomically divide the nervous system into two major regions: the central nervous system (CNS) is the brain and spinal cord, the peripheral nervous system (PNS) is the nerves (Figure 12.1.
1134585
The organs of the peripheral nervous system are the nerves and ganglia. ... The peripheral nervous system is further subdivided into an afferent (sensory) division and an efferent (motor) division. The afferent or sensory division transmits impulses from peripheral organs to the CNS.

The peripheral nervous system (PNS), which consists of the neurons and parts of neurons found outside of the CNS, includes sensory neurons and motor neurons.
