Question

True (A) or False (B): Vision impairment would typically occur (NOT rare exceptions!) if damaged occurred to the: 4. Optic nerve 5. Oculomotor nerve 6. Abducens nerve 7. Occiptal lobe of the cerebrum 8. Hypothalamus True (A) or False (B): Breathing impairment would typically occur (NOT rare exceptions!) if damaged occurred to the: 9. Pons 10. Corpus callosum 11. Medulla oblongata 12. Cerebellum 13. Phrenic nerve 14. Vagus nerve

Answer 1

Vision impairment occur if damage occurred to the occipital lobe of the cerebrum. It is located posterior site of brain and responsible for visual perception. If damage is occurred here then visual capacity become loss and inability to identify color pattern.

Hypothalamus is hormone stimulating organ and present under pituitory. Others such as optic nerve, oculomotor nerve, abdducens nerve all are responsible for proper visualization. If damage occur in any of these some muscle problem will occour and double vision can occour .

If phrenic nerve become damaged breathing impairment will occur. Because this nerve originated from neck pass through lung and heart and finally reach to diaphragm. This nerve is important for breathing.

Vagus nerve runs through thorax and it control thorax muscles. cerebellum present under the brain and it play a role in coordination in movement. Medulla oblongata maintain motor neuron connection between fore brain and mid brain. Cerebellum callosum devide the Cerebral cortex into 2 hemisphere (left & right). Pons present at the upper part of brain and play a role in balancing , hearing.
