what is the peripheral nervous system includes?

The peripheral nervous system refers to parts of the nervous system outside the brain and spinal cord. It includes the cranial nerves, spinal nerves and their roots and branches, peripheral nerves, and neuromuscular junctions.

Structure. The peripheral nervous system is divided into the somatic nervous system, and the autonomic nervous system. The somatic nervous system is under voluntary control, and transmits signals from the brain to end organs such as muscles.

The primary function of the peripheral nervous system is to connect the brain and spinal cord to the rest of the body and the external environment.

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. It contains three anatomically distinct divisions: sympathetic, parasympathetic and enteric.

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.

The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 1). The brain is contained within the cranial cavity of the skull, and the spinal cord is contained within the vertebral cavity of the vertebral column.

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. Sensory neurons bring signals into the CNS, and motor neurons carry signals out of the CNS.

The somatic peripheral nervous system is a single neuron system with the motor neurons lying inside the brainstem or spinal cord and the sensory neurons lying in the dorsal root ganglia. The autonomic peripheral nervous system is a two neuron system with a neuron lying outside of the CNS in the autonomic ganglia.

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.

SOMATIC NERVOUS SYSTEM (SNS) OF THE PNS (PERIPHERAL NERVOUS SYSTEM) CONSISTS OF: SENSORY NEURONS, CALLED SOMATIC SENSORY NEURONS, THAT CONVEY INFORMATION FROM SENSORY RECEPTORS IN THE SKIN, SKELETAL MUSCLES, JOINGS, AND FOR THE SPECIAL SENSES (VISION, HEARING, TASTE, AND SMELL) TO THE CNS.

The parasympathetic nervous system is also a subdivision of the peripheral nervous system. Like other subdivisions of the PNS, it also consists of nerve fibers leading to or originating from the brain and spinal cord. It also has neuronal cell bodies located in ganglia.

The Central and Peripheral Nervous Systems. The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else (Figure 1).

The other part of the nervous system is called the peripheral nervous system (PNS). This is made up of all the parts of the nervous system that are not part of the CNS.
