Synaptic Communication Flashcards
1
Q
Cerebrospinal fluid (CSF)
A
Maintains pressure between the brain and spinal cord.
Cushions the brain
Plays a minor role in fluid/waste exchange between the brain and spinal cord
2
Q
Myelin
A
Insulation of axon
Several layers wrapped around axons
Oligodendrocytes (Central)
Schwann cell (motor/peripheral)
3
Q
Cranial nerves
A
12 pairs that emerge from the brain, most of which are associated with the head/neck
4
Q
Structuress of the brain
A
Four anatomical regions- Cerebrum Diencephalon Brain stem Cerebellum
Each contains one or more structures.
5
Q
The cerebrum is…
A
About 2/3s of the brains mass
Lies over and around most of the structures of the brain.
Highly folded to increase surface area
Covered in a thin layer of grey matter called the cerebral cortex
6
Q
Functions of the cerebrum
A
Regulation of muscle contraction Memory processing and storage Production of speech Interpretation of taste Sound processing and storage
7
Q
Diencephalon
A
Provides a functional link between the cerebral hemispheres and the CNS Contains three paired structures: Thalamus Hypothalamus Epithalamus
