what is peripheral nervous system brainly?
479243
Peripheral nervous system: The portion of the nervous system that is outside the brain and spinal cord. Abbreviated PNS. The nerves in the PNS connect the central nervous system (CNS) to sensory organs, such as the eye and ear, and to other organs of the body, muscles, blood vessels, and glands.

The peripheral nervous system consists of two major divisions—the sensory division and the motor division. The sensory division of the peripheral nervous system transmits impulses from sense organs to the CNS. The motor division of the peripheral nervous system transmits impulses from the CNS to muscles or glands.

The parasympathetic nervous system (PSNS) is one of the two divisions, the other being the sympathetic, that together are called the autonomic nervous system, which is a division of another system called the peripheral nervous system (PNS)).

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.

The somatic system is the part of the peripheral nervous system that is responsible for carrying motor and sensory information both to and from the central nervous system (CNS). This system is made up of nerves that connect to the skin, sensory organs, and all skeletal muscles.

The brain and spinal cord make up the central nervous system. The peripheral nervous system is comprised of the somatic and autonomic nervous systems.

The Central Nervous System is the integration and command center of the body. It consists of the brain, spinal cord and the retinas of the eyes. The Peripheral Nervous System consists of sensory neurons, ganglia (clusters of neurons) and nerves that connect the central nervous system to arms, hands, legs and feet.

', 'The peripheral nervous system is subdivided into nerves, the autonomic system, and the somatic system. ...

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body. It is essentially the body's electrical wiring. Structurally, the nervous system has two components: the central nervous system and the peripheral nervous system.

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.

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

Our nervous system is divided in two components: the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which encompasses nerves outside the brain and spinal cord.

Peripheral Nervous System Functions The peripheral nervous system connects the brain and the spinal cord to the rest of the body and the external environment. It regulates the internal homeostasis. It can regulate the strength of the muscle contractility.

The somatic nervous system (SNS or voluntary nervous system) is the part of the peripheral nervous system associated with the voluntary control of body movements via skeletal muscles. The somatic nervous system consists of afferent nerves or sensory nerves, and efferent nerves or motor nerves.

The peripheral system allows the brain and spinal cord to receive and send information to other areas of the body, which allows us to react to stimuli in our environment. The nerves that make up the peripheral nervous system are actually the axons or bundles of axons from nerve cells or neurons.

Introduction. 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.

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.
