Brain |
Major portion of the central nervous system
|
|
Cerebrum |
Largest portion of the brain, into left and right hemispheres. The cerebrum controls the skeletal muscles, interpret general senses, and contain centers for sight and hearing. Intellect, memory, and emotional reactions also take place in the cerebrum.
|
|
Ventricles
|
Spaces within the brain that contain a fluid called cerebrospinal fluid. The cerebrospinal fluid flows through the subarachnoid space around the brain and spinal cord.
|
|
Cerebellum
|
Located under the posterior portion of the cerebrum. Its function is to assist in the coordination of skeletal muscles and to maintain balance.
|
|
Brain stem
|
stemlike portion of the brain connects with the spinal cord. 10 of the 12 cranial nerves originate in the brainstem.
|
|
Pons
|
Literally means bridge. It connects the cerebrum with the cerebellum and brain stem.
|
|
Medulla oblongata
|
Located between the pons and the spinal cord. It contains centers that control respiration, heart rate, and the muscles in the blood vessel walls, which assist in determining blood pressure.
|
|
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. It cushions the brain and spinal cord from shock, transports nutrients, and clear metabolic waste.
|
|
Spinal cord

|
|
Meninges
|
Three layers of membranes that cover the brain and spinal cord
|
|
Dura mater
