Study Guide on the Nervous System
| Question | Answer |
|---|---|
| Cerebrospinal fluid is made in the structures known as | choroid plexus |
| CSF is in the 2 large spaces inside each cerebral hemisphere know as the | lateral ventricles |
| From the lateral ventricles, CSF then moves through the interventricular foramen into a space known as the | 3rd ventricle |
| From the 3rd ventricle, CSF moves through the | central aqueduct into the 4th ventricle |
| From the fourth ventricle, CSF circulates in the spinal canal which is also known as the | central canal. CSF also moves from the fourth ventricle to the subarachnoid space. |
| CSF eventually is reabsorbed into the bloodstream (cranial venous sinus) by way of projections known as | arachnoid villi |
| The membrane covering the brain is know as the | meninges |
| Inflammation of the covering of the brain is know as | meningitis |
| The grooves or cracks between gyri in the cerebral cortex are known as | sulcus or fissure |
| The four main parts of the brain are | cerebrum, diencephalon, brain stem and cerebellum |
| The 2 structural divisions of the nervous system are | CNS and PNS |
| The 2 functional divisions of the nervous system are | Somatic and Autonomic |
| The parts of the interbrain are | thalamus and hypothalamus |
| The parts of the brain stem are | midbrain, pons and medulla oblongota |
| The functions of the cerebellum are | muscle tone, balance and coordinated voluntary movement. |
| The 8th cranial nerve is attached physically to the | pons |
| The 8th cranial nerve carries info that will be interpreted as hearing in the | temporal lobe of the cerebrum |
| The 8th cranial nerve also carries info that will assist with balance in the part of the brain known as the | cerebellum |
| The 1st cranial nerve carries sensory info to a lobe of the cerebrum known as the | temporal lobe (olfactory-smell) |
| The 10th cranial nerve carries to the thoracic and abdominal cavity organs that have a cholinergic (acetylocholine) affect. This means that the branch of the ANS known as the | parasympathetic branch has been activated. |
| The 7th cranial nerve sometimes is affected by a temporary disorder that causes one side of the face to be paralyzed. This disorder is known as | Bell's Palsy |
| The most frequently occurring disorder of the brain is a stroke, more accurately referred to as a | CVA (Cerebrovascular Accident) |
| In a huge number of cases prior to a stroke, the patient has experience a temporary spasm of the affected vessel, causing signs and symptoms of a stoke that come and then go away. This is highly predictive of a future stroke and is know as a | TIA (Transient Ischemic Attack) |
