9 Cards in this Set
- Front
- Back
|
What are the basic parts of the brain |
Brain stem (midbrain, pons, medulla oblongata)
Cerebellum
Cerebrum
Diencephalon |
|
|
What is the Cortex?
(Deep gray matter)? |
The most external layer of the brain
Gray matter
(Deep gray matter is also referred to nuclei or ganglia) |
|
|
Ventricles |
Filled with cerebral spinal fluid |
|
|
Medulla oblongata |
White matter-
1. Ascending somatic sensory tracts - axons carrying signals up
2. Descending corticospinal tracts- motor -coming from Cortex going to spinal cord
Gray matter controls involuntary functions |
|
|
Pons |
Relay station between cerebrum and cerebellum
Control of breathing |
|
|
Midbrain |
Controls eye movement |
|
|
Cerebellum |
Works with other parts of the brain to direst movement
Makes movements smoother more coordinated
Helps maintain posture and equilibrium
Motor memory
( Has propioceptors that tell you where you are without having to see .. Like having arms out ) |
|
|
Cerebellar peduncles |
2 way tracts-
Superior - connects cerebellum to midbrain
Middle - connects cerebellum to pons
Inferior - connects cerebellum to medulla oblongata |
|
|
Diencephalon: thalamus, hypothalamus, epithalamus |
Thalamus
Paired- receivers sensory info from all senses except olfaction
Relay center, processing, receives motor info from cerebellum
Hypothalamus
Homeostasis center
Center for behavioral drives (hunger, thirst)
Influences endocrine system
Influences autonomic Division of NS
Epithalamus
Pineal gland- secrets melatonin (wake sleep cycle)
