|
||||
| Coronal Section | 1. Formed by thalamus and hypothalamus
2. borders 3rd ventricle

🗑
|
||||
| Thalamus | 1. GATEWAY TO CEREBRAL CORTEX
2. makes up 80% of diencephalon
3. every part of brain that communicates with cerebral cortex must relay its signal through a nucleus of thalamus
4. has many nuclei that send axons out through the cerebral cortex
🗑
|
||||
| Hypothalamus | 1. lies below the thalamus
2. dozen nuclei like thalamus
3. in charge of visceral sense (hunger, body temperature, emotions etc.

🗑
|
||||
| Pituitary gland | 1. Controls secretion of HORMONES
-part of hypothalamus that projects inferiorly from hypothalamus
-anterior and posterior parts
🗑
|
||||

2. contains only ONE nuclei
3. PINEAL GLAND
🗑
|
||||
| Pineal Gland | 1. part of epithalamus that produce melatonin by influence of hypothalamus
2. helps regulate sleep-wake cycls
🗑
|
||||

2. Passageway for ALL FIBER TRACTS running between cerebrum and spinal cord
🗑
|
||||
| Brain Stem 3 parts | 1. Midbrain
