Chapter 49: Q49-2TYU (page 1104)

Which of the following structures or regions isincorrectlypaired with its function?

(A) limbic system鈥攎otor control of speech

(B) medulla oblongata鈥攈omeostatic control

(C) cerebellum鈥攃oordination of movement and balance

(D) amygdala鈥攅motional memory

Short Answer

Expert verified

(A)The option 鈥渓imbic system鈥攎otor control of speech鈥� iscorrect.

(B)The option 鈥渕edulla oblongata鈥攈omeostatic control鈥� isincorrect.

(C)The option 鈥渃erebellum鈥攃oordination of movement and balance鈥� iscorrect.

(D)The option 鈥渁mygdala鈥攅motional memory鈥� is correct.

Step by step solution

01

Central nervous system

The central nervous system is the system that controls and coordinates the body. The body's balance, posture, movement, and all the voluntary and involuntary actions of the body are governed by the central nervous system.

02

Explanation of option ‘(A)’

The limbic system oversees controlling the body's speech and voice. Speech and emotional vocals such as laughing or sobbing are influenced by the limbic vocal motor circuit. While the limbic system is activated, the speech's purpose is also activated.

Thus, the limbic system and motor control are correctly paired.

Therefore, the given option is correct.

03

Explanation of option ‘(B)’

The medulla oblongata is present in the brain stem that regulates the blood pressure of the body. The endocrine system of the body regulates the homeostatic control of the body.

Thus, the medulla oblongata and homeostatic control is an incorrect pair

Therefore, the given option is incorrect.

04

Explanation of option ‘(C)’

The function of the cerebellum in the brain is the control and coordination of the body. The other function of the cerebellum includes control over balance, walking, standing, and other mechanical functions of the body.

Thus, the cerebellum and its function control and coordination are correctly paired.

Therefore, the given option is correct.

05

Explanation of option ‘(D)’

Amygdala has a key role in emotional memory. It supports memory for emotionally arousing experiences. The activity of the amygdala is observed in the formation of long-term memory for emotional events.

Thus, the amygdala and emotional memory are correctly paired.

Therefore, the given option is correct.

How can studying individuals with damage to a particular brain region provide insight into the normal function of that region?

What general trends does the graph above reveal about the circadian cycle period of the transplant recipients? Do the trends differ for the wild-type and 饾洉 recipients? Based on these data, what can you conclude about the role of the SCN in determining the period of the circadian rhythm?

Consider an individual who had been fluent in American Sign Language before suffering an injury to his left cerebral hemisphere. After the injury, he could still understand that sign language but could not readily generate sign language that represented his thoughts. Propose two hypotheses that could explain this finding. How might you distinguish between them?

Suppose you examine two groups of individuals with CNS damage. In one group, the damage has resulted in a coma (a prolonged state of unconsciousness). In the other group, it has caused paralysis (a loss of skeletal muscle function throughout the body). Relative to the position of the midbrain and pons, where is the likely site of damage in each group? Explain.

The cerebral cortex doesnotplay a major role in

(A) short-term memory.

(B) long-term memory.

(C) circadian rhythm.

(D) breathholding.
