DescriptionTerm
A large, convoluted structure on the brain stem's dorsal surface, important sensorimotor structure
Glial cells with extensions that wrap around the azons of some neurons of the CNS
A class of glial cells that protect and increase speed of axonal conduction in the PNS
Innermost meninx, delicate and adheres to surface of CNS
Several classes of nonneural cells of the nervous system, support and nourish neurons
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
The outer meninx, a tough membrane
Part of PNS that regulates body's internal environment
Composed largely of myelinayed axons
Protects CNS, fills subarachnoid space, central canal of spinal cord, and cerebral ventricles of the brain
Three protective membranes surrounding the brain
Study of biological processes by comparing difference species
12 pairs of nerves that project from the brain
Carry sensory signals from the skin, skeletal muscles, joints, eyes, ears, etc, to CNS
Cells that are specialized for the reception, conduction, and transmission of electrochemical signals
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
Networks of paillaries that protrude into the ventriles from the pia mater and produce CSF

A method of measuring brain activity through the scalp
Clusters of cell bodies in CNS
Sensory(afferent) unipolar neurons with their cell bodies grouped together just outside the spinal cord
A fatty insulating substance found around axons
Clusters of cell bodies in PNS
Under arachnoid membrane, a space that contains many large blood vessels and CSF
Consists of brain and spinal cord
