Synaptic Communication Flashcards
(7 cards)
Cerebrospinal fluid (CSF)
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
Myelin
Insulation of axon
Several layers wrapped around axons
Oligodendrocytes (Central)
Schwann cell (motor/peripheral)
Cranial nerves
12 pairs that emerge from the brain, most of which are associated with the head/neck
Structuress of the brain
Four anatomical regions- Cerebrum Diencephalon Brain stem Cerebellum
Each contains one or more structures.
The cerebrum is…
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
Functions of the cerebrum
Regulation of muscle contraction Memory processing and storage Production of speech Interpretation of taste Sound processing and storage
Diencephalon
Provides a functional link between the cerebral hemispheres and the CNS Contains three paired structures: Thalamus Hypothalamus Epithalamus
