| Question | Answer |
|---|---|
| what is the purpose of the meninges in the brain | protection |
| does the brain have epidural space? | no |
| which of the following adhears to the skull: dura mater, arachnoid mater, pia mater | dura mater |
| which of the following adhears to the surface of the brain: dura mater, arachnoid mater, pia mater | pia matter |
| What is the percentage of oxygen and glucose that the brain uses | 20% |
| what is the purpose of the blood brain barrier | protection from harmful substances |
| what type of cells make up the blood brain barrier | epithelial cells |
| what can pass through the blood brain barrier | glucose, oxygen, carbon dioxide, alcohol |
| What can't pass through the blood brain barrier without active transport | proteins, most antibiotics |
| where is cerebral spinal fluid found | in subarachnoid apce and ventricles |
| what is the function of the cerebral spinal fluid | to protect the brain and spinal cord |
| what is hydrocephaly | "water on the brain" - condition where brain stops absorption or production of cerebral spinal fluid |
| what absorbs cerebral spinal fluid back into the blood stream | arachnoid villi |
| where is the choroid plexus found and what does it make | lines ventricles and makes cerebral spinal fluid |
| what three things make up the brainstem | medulla oblongata, pons and midbrain |
| what does teh medulla oblongata control | cardiovascular adn respiratory activity |
| what tracts travel through the medulla oblongata | ascending and descending tracts |
| the medually oblongata is the nucleii for what cranial nerves | 8-12 |
| this part of the brain is the relay center for ascending and descinding tracts - helps dictate where neuron impulses go | pons |
| this part of the brain connects the midbrain to the medulla and the right and left hemispheres | pons |
| the pons is the nuclei for which cranial nerves | 5-7 |
| located between the pons and diencephalon | midbrain |
| the midbrain is the nuclei for which cranial nerves | 3-4 |
| the corpora quadrigemina is what part of the brain | midbrain (above pons and cerebelum) |
| what does the quadrigemina include | 4 bumps on the sides of the midbrain: superior colliculi and inferior colliculi |
| what does the superior colliculi do for the body | track movign objects with eyes, head and neck |
| what does the inferior colliculi do for the body | reflex moving head and trunk responding to sound |
| the substantia nigra and red nucleus are both part of this part of the brain | midbrain |
| what does the substantial nigra do for the body | subconscious muscle control |
| what does the red nucleus do for the body | control muscle movement |
| what separates the cerebellum from the cerebrum | transverse fissure |
| what does the cerebellum do for the body | fine muscle movement, regular posture, balance and coordiate complex movements |
