organs and structures (15, 16) Flashcards
brain
contained within the cranium, center for coordinating body activities
cerebrum
largest portion of the brain, divided into left and right hemispheres
ventricles
cavities within the brain that contain cerebrospinal fluid (CSF)
serebellum
located under the posterior portion of the cerebrum
brainstem
stemlike portion of the brain that connects with the spinal cord; contains centers that control respiration and heart rate
pons
literally means bridge –> connects cerebrum with cerebellum and brainstem
medulla oblongata
located between the pons and spinal cord
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
passes through the vertebral canal extending from the medulla oblongata to the level of the second lumbar vertebra
meninges
three layers of membrane that cover the brain and spinal cord
dura mater
though other layer of the meninges
arachnoid
delicate middle layer of the meninges
pia mater
thin inner layer of the meninges
nerve
cordlike structure made up of fibers that carries impulses from one part of the body to another
