InfoTerm
Carry nerve impulses away from the central nervous system
Type of glial cell important in peripheral nerve biology— conduction of nervous impulses along axons, nerve development & regeneration, trophic support for neurons
The development of myelin sheaths is known as this
Cells that coat axons in the CNS with their cell membrane, forming a specialized membrane differentiation called myelin
Dielectric material that forms a namesake layer usually around only the axon of a neuron/is an outgrowth of a type of glial cell
The bulbous end of a neuron that contains the cell nucleus, often called the cell body
Small cells of the PNS that surround neurons in sensory, sympathetic, and parasympathetic ganglia. They help regulate the external chemical environment
Set of 12 nerves that emerge directly from the brain and the brainstem/include olfactory, optic, facial, & oculomotor
Responsible for stimulating skeletal muscles, the only consciously controlled part of the peripheral nervous system
Specialized macrophages capable of phagocytosis that protect neurons of the central nervous system, multiply when the brain is damaged
They line the spinal cord and the vetricular system of the brain, they are involved in the creation and secretion of cerebrospinal fluid
Lower half of the brainstem, which is continuous with the spinal cord
Short lasting event in which the electrical membrane potential of a cell rapidly rises and falls, in neurons it plays a role in cell communication
Involuntary part of the Peripheral nervous system
The branched projections of a neuron, they play a critical role in integrating synaptic inputs and in determining the extent to which action potentials are produced by a neuron
Longest and widest single nerve in the human body, going from the top of the leg to the foot on the posterior aspect
Protective coverings of the central nervous system
11th cranial nerve that controls the sternocleidomastoid and trapezius muscles
InfoTerm
Longest nerve of autonomic nervous system & longest cranial nerve/interfaces w/parasympathetic control of heart & digestive tract/historically called pneumogastric nerve
Carry nerve impulses from receptors or sense organs toward the central nervous system
Consists of brain and spinal cord, it integrates information it recieves and influences the activity of all parts of the body
Governs the function of the gastro intestinal system
5 pairs of spinal nerves which exit sacrum at lower end of vertebral column/responsible for part of sensory perception & movements in lower extremities of body
Responsible for the stimulation of rest and digest or feed and breed activites that occur when the body is at rest
Junction between a neuron and another cell
12th cranial nerve that innervates all extrinsic and intrinsic muscles of the tongue, except for the palatoglossus
The most abundant type of macroglial cells in the CNS, they have numerous projection that link neurons to their blood supply while, regulate external chemical environment
Sticky buildup which accumulates outside nerve cells, or neurons/beta-versions damage signaling & contribute to Alzheimer's Disease
Endogenous chemicals that transmit signals across a synapse from one neuron to another neuron, packaged into synaptic vesiscles
Stimulates the bodies flight or fight response
Act as the helper cells of the nervous sytem, the neuroglia protect, feed ,and insulate neurons in the body
Communicate within the body using electrochemical signals
Arise from nueroepithelial cells after the onset of neurogenesis, function as neuronal progenitors and as a scaffold upon which newborn neurons migrate
Function is to transmit information to different neurons, muscles and glands
Largest unprotected nerve in the human body, directly connected to the little finger
