Chap 13 part III
Diencephalon and onward
| Question | Answer |
|---|---|
| Diencephalon | 1. forms center core of forebrain 2. Three parts: Thalamus, Hypothalamus, and Epithalimus |
| Coronal Section | 1. Formed by thalamus and hypothalamus 2. borders 3rd ventricle 3. made mostly of grey matter |
| 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. 4. PITUITARY GLAND |
| Pituitary gland | 1. Controls secretion of HORMONES -part of hypothalamus that projects inferiorly from hypothalamus -anterior and posterior parts |
| Epithalamus | 1. most dorsal part of diencephalon 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 |
| Brain Stem | 1. produces automatic behavior necessary for survival 2. Passageway for ALL FIBER TRACTS running between cerebrum and spinal cord |
| Brain Stem 3 parts | 1. Midbrain 2. Pons 3. Medulla Oblongata |
| Midbrain | 1. most superior structure of brain stem |
| Midbrain seven parts | 1. Periaqueductal Gray Matter 2. Cerebral Peduncles 3. Superior Cerebellar Peduncles 4. Corpora quadrigemina of tectum 5. Substantia Nigra 6. Red nucleus |
| Periaqueductal Grey Matter | 1. Part of Midbrain of brainstem 2. related to fight/flight reaction |
| Corpora quadrigeminaof tectum | 1. Two parts: Superior Colliculi and Inferior Colliculi |
| Superior Colliculi | part of Corpora quadrigeminaof tectum of midbrain of brainstem that is responsbile for visual reflexes |
| Inferior Colliculi | part of Corpora quadrigeminaof tectum of midbrain of brainstem that are responsible for reflexes to sound |
| Substantia Nigra | degradation of this is linked to Parkinson's disease |
| Pons | 1. under midbrain in brainstem 2. above medulla oblongata 3. Pontine Nucleus 4. Contains nuclei of Cranial Nerves 5-7 |
| Middle cerebellar peduncle | -connects pons to cerebellum |
| Medulla Oblangata | -continuous with spinal cord at forament magnum -contains cerebral nerves 8-12 |
| Medulla Oblangata 3 Parts | 1. Pyramids of Medulla 2. Reticular Formation 3. Inferior Cerebellar Peduncle |
