DescriptionTerm
Several classes of nonneural cells of the nervous system, support and nourish neurons
Networks of paillaries that protrude into the ventriles from the pia mater and produce CSF
Glial cells with extensions that wrap around the azons of some neurons of the CNS
Composed largely of cell bodies and unmyelinated interneurons
Everything but the brain and spinal cord
A membrane (spiderweb-like) directly beneath dura mater
Consists of brain and spinal cord
Protects CNS, fills subarachnoid space, central canal of spinal cord, and cerebral ventricles of the brain
A fatty insulating substance found around axons
Three protective membranes surrounding the brain
A method of measuring brain activity through the scalp
A large, convoluted structure on the brain stem's dorsal surface, important sensorimotor structure
Bundles of axons in PNS
Under arachnoid membrane, a space that contains many large blood vessels and CSF
Bundles of axons in CNS
Clusters of cell bodies in CNS
A class of glial cells that protect and increase speed of axonal conduction in the PNS
The largest, star-shaped glial cells that play a role in allowing the passage of some chemicals from the blood into CNS neurons and in blocking other chemicals, also control establ
Composed largely of myelinayed axons
Large furrows in a convoluted cortex
DescriptionTerm
Four large internal chambers of the brain
The outer meninx, a tough membrane
Cells that are specialized for the reception, conduction, and transmission of electrochemical signals
Large, multipolar neurons with pyramid-shaped cells bodies
Those autonomic motor nerves that project fomr the brain and sacral region of the spinal cord
Located just below the anterior thalamus; plays an important role in the regulation of several motivated behaviors and release of hormones from pituitary
Carry sensory signals from the skin, skeletal muscles, joints, eyes, ears, etc, to CNS
Study of biological processes by comparing difference species
Clusters of cell bodies in PNS
Small furrows in a convoluted cortex
Ridges between fissures and sulci
Those autonomic motor nerves that project from the CNS in the lumbar and thoracic regions of the spinal cord
Sensory(afferent) unipolar neurons with their cell bodies grouped together just outside the spinal cord
A layer of blood vessel cells that are very tightly packed and selectively permeable
12 pairs of nerves that project from the brain
Carry motor signals from the CNS to skeletal muscles
A circuit of midline structures that circle the thalamus; involved in regulating motivated behaviors
Part of PNS that regulates body's internal environment
Innermost meninx, delicate and adheres to surface of CNS
