Deep in Forebrain
Questions
| Question | Answer |
|---|---|
| What is the name of the Gray Matter bilateral to the Thalamus, and what does it do? | Basal Nuclei - Adjusts and Subdues MOTOR activity |
| What is the function of the Limbic System? | Regulates BEHAVIORAL aspects of Major Emotions: Pain, Guilt, Rage, Pleasure, Sexual Satisfaction, and LONG Term Memory |
| Where is the Limbic System located? | around Lateral Ventricles deep within the Forebrain |
| What is the Thalamus? | a relay SENSORY point for information to be passed to the Primary Sensory Area of Cerebral Cortex |
| What is the function of the Thalamus? | allows crude Appreciation of MOST Sensations - Directs and Coordinates MOTOR activities |
| Where is the Thalamus located? | deep GRAY Matter medial to the Basal Nuclei |
| What is the function of the Hypothalamus? | 1. Regulates BEHAVIOR associated with FEAR; 2. controls most of the AUTONOMIC nervous system; 3. regulates survival functions: Thermoregulation, Appetite, Sexual Desire; 4. controls secretion of Pituitary gland |
| What structure of gray matter forms the floor of the 3rd Ventricle? | Hypothalamus |
| Where do the 1st and 2nd Ventricles drain into? | into the 3rd Ventricle via INTERventricular Foramen |
| Where are the 1st, 2nd, and 3rd Ventricles located? | deep within the Cerebrum |
| Where is the 4th Ventricle located? | Hindbrain, between the Medulla and Cerebellum |
| What is the Cerebral Aqueduct? | the canal by which the 3rd Ventricle drains into the 4th |
| Where does the 4th Ventricle drain into? | Median and Later Apertures to the Subarachnoid Space (SAS) |
| Which Ventricle(s) reaches into all lobes of the brain? | 1st and 2nd Ventricles |
| How is CSF formed? | secreted from ALL Ventricles by the Choroid Plexus |
| What is the composition of CSF? | similar to blood Plasma, with less Protein |
| How is CSF absorbed? | through the Arachnoid Villi into the Superior Sagittal Sinus |
| What is the function of CSF? | 1. Shock Absorption; 2. Internal Support; 3. Transports Nutrients and Wastes |
| What is the path of CSF? | 1st and 2nd Ventricles --> Interventricular Foramen --> 3rd Ventricle --> Cerebral Aqueduct --> 4th Ventricle --> Median and Lateral Apertures --> Subarachnoid Space |
