- 5) Describe what would happen to the myotatic (stretch) reflex in each of the following conditions (get larger,smaller, stay the same, or disappear). Be sure to explain your answers and describe what part of the reflex hasbeen affected by the treatment.a. A complete transection of the spinal cord at the C5 level (look at the dermatome picture in the slides)b. Destruction of the cells in the dorsal root ganglionc. Synaptic depression at the Ia/motor neuron synapsed. Partial destruction of the ventral root1. 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.
