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