Brain
Contained within the cranium, the center for coordinating body activities
Cerebrum
largest and most complex part of the brain, made up of the left and right hemispheres
Ventricles
spaces located in the inner brain that contain cerebrospinal fluid
Cerebellum
the "little brain" at the rear of the brainstem; functions include processing sensory input and coordinating movement output and balance
Brainstem
Stemlike portion of the brain that connects with the spinal cord.
pons
literally means bridge; It connects the cerebrum with the cerebellum and brain stem.
medulla oblongata
most inferior portion of brain stem;
regulates vital body functions, such as: heart rate, blood pressure, breathing, swallowing, and wakefulness, and consciousness
Midbrain
most superior portion of the brainstem.
cerebrospinal fluid (CSF)
clear, colorless fluid contained in the ventricles that flows through the subarachnoid space around the brain and spinal cord.
Spinal cord
column of nervous tissue from the brainstem through the vertebrae; responsible for nerve conduction to and from the brain and the body
Meninges
three layers of membranes that cover the brain and spinal cord
dura mater
tough outer layer of the meninges
arachnoid
delicate middle layer of the meninges; the arachnoid membrane is loosely attached to the pia mater by weblike fibers, which allow for the subarachnoid space
Pia mater
the third layer of the meninges, located nearest to the brain and spinal cord
Nerve
whitish cordlike structure that transmits stimuli from the central nervous system to another area of the body or from the body to the central nervous system
Ganglion
group of nerve cell bodies located outside the central nervous system
Glia
Specialized cells that nourish and support neurons.
Neuron
cell that carries messages throughout the nervous system
