Group C nerve fibers are one of three classes of nerve fiber in the central nervous system (CNS) and peripheral nervous system (PNS). The C group fibers are unmyelinated and have a small diameter and low conduction velocity, whereas Groups A and B are myelinated. Group C fibers include postganglionic fibers in the autonomic nervous system (ANS ...
Schwann cell. Schwann cells (red, cylindral cells at bottom) on a neuron (yellow) in the PNS. Schwann cells or neurolemmocytes (named after German physiologist Theodor Schwann) are the principal glia of the peripheral nervous system (PNS). Glial cells function to support neurons and in the PNS, also include satellite cells, olfactory ...
The peripheral nervous system ( PNS) is one of two components that make up the nervous system of bilateral animals, with the other part being the central nervous system (CNS). The PNS consists of nerves and ganglia, which lie outside the brain and the spinal cord. [ 1] The main function of the PNS is to connect the CNS to the limbs and organs ...
Schwann cell. 4. Myelin sheath. 5. Neurilemma. Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann's sheath) [ 1] is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron. It forms the outermost layer of the nerve fiber in the peripheral nervous system. [ 2]
This is a list of digicams that contain a 1/1.7″ CCD sensor or larger, include a fixed lens, and support SDHC memory cards and one or more of the following: SDXC memory cards, [ 6] raw image format capture, [ 7] and AA or AAA batteries. [ a] These are features that help make an old camera easy to use today. Notably, no Fujifilm Super CCD ...
Cranial nerves are the nerves that emerge directly from the brain (including the brainstem ), of which there are conventionally considered twelve pairs. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck, including the special senses of vision, taste, smell, and hearing.
The classification of peripheral nerves in the peripheral nervous system (PNS) groups the nerves into two main groups, the somatic and the autonomic nervous systems. [ 1] Together, these two systems provide information regarding the location and status of the limbs, organs, and the remainder of the body to the central nervous system (CNS) via ...
An axon (from Greek ἄξων áxōn, axis) or nerve fiber (or nervefibre: see spelling differences) is a long, slender projection of a nerve cell, or neuron, in vertebrates, that typically conducts electrical impulses known as action potentials away from the nerve cell body. The function of the axon is to transmit information to different ...
