The peripheral nervous system (PNS) is the part of the nervous system outside the CNS. The PNS consists mainly of nerves (bundles of axons) that extend from the brain and spinal cord, and ganglia (collections of neuron cell bodies). Spinal nerves carry impulses to and from the spinal cord, and cranial nerves carry impulses to and from the brain.

The central and peripheral nervous system (CNS and PNS, respectively) are composed of distinct neuronal and glial cell types with specialized functional properties. However, a small number of select cells traverse the CNS-PNS boundary and connect these two major subdivisions of the nervous system.This pattern of segregation and selective

The functional classification of neurons is based on electrophysiological properties (excitatory or inhibitory) and the direction in which the AP is conveyed with respect to the CNS. Sensory or afferent neurons convey APs into the CNS through cranial or spinal nerves. Most are unipolar. Motor or efferent neurons convey APs away from the

The nervous system has two major subdivisions: the central nervous system (CNS) consisting of the brain and spinal cord, and the peripheral nervous system (PNS), consisting of everything outside the CNS. The CNS can be thought of as the command-and-control portion of the nervous system. The PNS represents a

The sensory division is the division that contains the nerve fibers that carry impulses to the CNS from sensory receptors that are located throughout the body. There are two types of sensory fibers. The somatic afferents convey information from the skin, skeletal muscles, and

- PNS is responsible for functions #1 (monitoring) & #3 (motor output). * Monitors changes, sends info to the CNS, then carries motor output. - Divided into functional regions: 1) SENSORY or AFFERENT ( towards ); info from receptor to CNS. 2) MOTOR or EFFERENT ( away ); info from CNS to effectors. The Motor System can be further subdivided:

Functional classification:according to the direction of the impulse a. Sensory (afferent): the impulse direction is toward the CNS 1) Cell bodies:located in clumps called ganglia in the PNS 2) All sensory neurons are unipolar 3) They typically possess a long dendrite b. Motor (efferent): the impulse direction is away from the CNS

PNs in mice. Through immunological, genetic and viral labeling, we identify three groups of PNs that correspond to the known functional subtypes (Ia, Ib and II) and provide long-awaited genetic markers to target them individually. We also unveil subtypes within Ia- and II-PNs (Ia 1/2/3-PNs and II 1/2/3/4

Human Physiology/The Nervous System

The nervous system is comprised of two major parts, or subdivisions, the central nervous system (CNS) and the peripheral nervous system (PNS). The CNS includes the brain and spinal cord. The brain is the body's control center The CNS has various centers located within it that carry out the sensory, motor and integration of data.
