The innermost meningeal layer is the 4. The gland associated with the hypothalamus is the 5. What two brain structures are characterized by inner white matter surrounded by gray matter called the cortex? Introduction There are four major divisions of the brain: cerebrum, diencephalon, cerebellum, and brainstem Figure 10. 100 illustrates these four divisions. There are 12 pairs of cranial nerves associated with the brain that will be studied separately in Section 10.3 of the Nervous System Unit 10 L N1. Amanda Momoni, was involved in a brutal fight at Kwame Nkrumah circle and had his posterior part of his skull damaged. Upon his arrival at the hospital, his blood pressure was 180/100 mmHg. He was quickly injected intravenously with cholinergic drug that reduced the blood pressure to normal. He was also found to lose his vision sense upon his wake. Several electrocardiogram results and other Heart function test indicated he could probably have a congenital heart disease (hole in heart); I. Describe how the blood pressure was regulated.II. Briefly explain the cause of his vision problems. III. Describe anatomical how he had this congenital heart defect (use diagrams to support your descriptions.IV. List the components of the heart conduction system .Identify TRUE or FALSE 1. The cells that conduct messages towards the brain are the interneurons.2. Nerves impulses always travel to the brain through nerve fibers.3. The presence of myelin gives a nerve fiber its white color and increased rate of impulse transmission.4. Saltatory conduction involves Schwann cells and occurs at greater speed than onunmyelinated fibers.5. The neuron cannot be stimulated during the absolute refractory period.6. The speed of a nerve impulse is independent of the presence of myelin.7. The tightly packed coil of neurolemmocyte membrane that encircles certain kinds ofaxons is called a node.8. Depolarization of the membrane of a nerve cell occurs by the rapid influx of organic ions.9. In a resting neuron the outside is negatively charged.10. The interior surface of a membrane of a nonconducting neuron differs from the exteriorsurface in that the former is negatively charged and contains more sodium.
