Unit 6b Flashcards
4 Regions of brain (BCCD)
- Brainstem (midbrain, pons, medulla oblongata)
- Cerebrum - largest (at top)
- Cerebellum - most neurons (at base)
- Diencephalon - between crerubrum and mdibrain)
gyRi are __ of the brain
Ridges
Suchi are _ of the brain
stems
Longitudinal fissue is a deep _ that divides the _ into left and right hemispheres
deep groove
divides cerebrum
Corpus callosum is a bundle of _ that connects the left and right _
bundle of NERVES
connects left & right HEMISPHERES
Gray matter is _ of the brain: responsible for _
surface
learning
White matter is underneath the _ _
cerebral cortex
Two mater has two layers. The P_ later is attached to _;
The M_ layer covers the _
Periosteal - attached to SKULL
Meningeal layer covers the BRAIN (continues to spinal later)
SUBDURAL space separates the dura mater from the a_ mater
Arachnoid
SUARACHNOID space spearates the archnoid mater from the p_ mater
pia
CerebroSPINAL fluid fills the the v_ and the c_ canal. It also bathes _ (inside or outside) of brain and spinal cord
ventricles
and central canal
bathes OUTSIDE of brain
Blood brain barrier are formed as a_cytes wrap around c_
ASTROCYTES wrap around CAPILLARIES
Blood brain barrier p_ brain from foreign substances
protects
MIDBRAIN is part of brain stem which relays SENSORY and MOTOR i__:
MIDBRAIN also has auditory and visual r_ and clusters of n_ important for muscle growth
impulses
audio and visual REFLEXES
clusters of NEURONS
PONS is part of the brain stem that contains tracts that convey s_ to and from diff parts of brain
conveys SIGNALS
