Exam 4 Flashcards
Brains role
Information processing, memory, emotion
97% of nerve tissue
Four major regions of the brain
-cerebrum
-Cerebellum
-diencephalon
-brainstem
Cerebrum
Intellect, memory, personality
Cerebellum
Repeated patterns like walking
Diencephalon
Mid brain, compose of thalamus and hypothalamus
Brain stem
Contains neurons that connect cerebrum and cerebellum
Thalamus
All sensation pass through here (taste, hearing,vision…) , traffic director for impulse
Hypothalamus
Controls homeostatic mechanisms, eating reflexes, hormones
3 structures of the brain stem?
-Midbrain
-pons
-medulla oblongata
Midbrain
Superior part of brain stem, smooth motor function
Pons
Links brain to cerebellum, motor info to cerebellum
Medulla oblongata
Autonomic functions
Ventricals *
-space that makes CSF
- four chambers in the brain
- chorachoid plexus is a region of capillary’s within that makes CSF
- CSF supports and cushions brain, transports waste, nutrients, and chemical messages
Carotid artery
Delivers blood to the brain, high blood pressure
Blood brain barrier
Astrocytes appendages wrap around capillaries
Proprioception
Awareness of body position
