Question type: Essay

 

 

45) In 1848, a railroad worker named Phineas Gage was seriously injured during an explosion on the job. A tapered metal rod ranging from 0.25 inches to 1.25 inches in diameter and over 3 feet long entered his skull just under his left cheek bone and exited through the top of his skull. The rod was found over twenty feet away. Amazingly, Gage lived even though he suffered massive damage to the left front of his brain. His personality and intellectual abilities changed, however. Before the accident, he was respected as a smart, capable and even-tempered man. After the accident, he was foul-mouthed and bad-tempered and could not make up his mind. In the years immediately preceding his death, he began to have epileptic seizures. Explain the changes observed in Mr. Gage based on your knowledge of the brain.

 

Answer:

 

Difficulty: Hard

Study Objective 1: SO 14.7 Describe the location and functions of the sensory, association and motor areas of the cerebral cortex and the importance of hemispheric lateralization, and brain wave activity.

Study Objective 2: SO 14.7.1 Describe the locations and functions of the sensory, association, and motor areas of the cerebral cortex.

Section Reference 1: Sec 14.7 Functional Organization of the Cerebral Cortex

Solution: The accident apparently damaged the frontal lobe and specifically the prefrontal cortex of the left side of Mr. Gage’s brain. The frontal lobe is involved in memory and intellect. The prefrontal cortex is involved in judgment, ethics, and conscious. The changes Mr. Gage experienced indicate that the right side of his brain could not compensate for the losses on the left side of the brain. It is remarkable that the story doesn’t mention that Mr. Gage lost some motor function on his right side since it is controlled by the primary motor region on left side of the brain. There is also no mention of loss of speech, which is largely processed on the left side of the brain. Perhaps the iron rod just missed those areas. As far as the epileptic seizures are concerned, it is possible that the accident damaged the basal ganglia to some degree. As he aged and lost connections between neurons that damage might have become more evident as the basal ganglia could no longer communicate effectively with the rest of the brain.

 

 

46) Describe the structural and functional relationship between the hypothalamus and the pituitary gland.

 

Answer:

 

Difficulty: Medium

Study Objective 1: SO 14.5 Describe the components and functions of the diencephalon (thalamus, hypothalamus, and epithalamus).

Section Reference 1: Sec 14.5 The Diencephalon

Solution: The hypothalamus releases regulatory hormones into the capillary networks in the median eminence to increase or decrease hormone production and secretion from the anterior pituitary. Axons from the paraventricular and supraoptic nuclei extend through the infundibulum to the posterior pituitary. Their cell bodies produce oxytocin or antidiuretic hormone, which through axonal transport these hormones are moved into the posterior pituitary where they are stored and released from the axon terminals.
