a. Afferent neuron transmits signal of CNS.
b. The choroid layer is bluish color and is present over the posterior two-thirds of the eyeball.
c. Olfactory bulbs are an extension of the hypothalamus
d. Medulla oblongata have centre to control excretion, circulation, and gastric secretion.
1. One
2. Two
3. Three
4. Four
Which part of the human brain is concerned with the regulation of body temperature?
1. Medulla oblongata
2. Cerebellum
3. Cerebrum
4. Hypothalamus
Select the answer with correct matching of the structure, its location and function:
| A | B | C | |
| 1. | Cerebellum | Mid brain | Controls respiration and gastric secretions |
| 2. | Hypothalamus | Fore brain | Controls body temperature, urge for eating and drinking |
| 3. | Blind spot | Near the place where optic nerve leaves the eye | Rods and cones are present but inactive here |
| 4. | Eustachian tube |
Anterior part of internal ear | Equalizes air pressure on either sides of tympanic membrane |
The nerve centres which control the body temperature and the urge for eating are contained in:
1. hypothalamus
2. pons
3. cerebellum
4. thalamus
1. Corpus callosum and thalamus
2. Limbic system & hypothalamus
3. Corpora quadrigemina & hippocampus
4. Brain stem & epithalamus
Which part of the brain is responsible for thermoregulation?
1. Medulla oblongata
2. Cerebrum
3. Hypothalamus
4. Corpus callosum
Injury localized to the hypothalamus would most likely disrupt:
1. short-term memory
2. co-ordination during locomotion
3. executive functions, such as decision making
4. regulation of body temperature
| Column I | Column II | |
| 1. | Medulla oblongata | controls respiration and cardiovascular reflexes. |
| 2. | Limbic system | consists of fibre tracts that interconnect different regions of brain; controls movement. |
| 3. | Hypothalamus | production of releasing hormones and regulation of temperature, hunger and thirst. |
| 4. | Corpus callosum | band of fibers connecting left and right cerebral hemispheres. |
Which of the following statements are true regarding
association areas of brain?
A. These are the largest areas of forebrain.
B. These are involved in the regulation of sexual
behaviour, expression of emotional reactions
and motivation.
C. These are responsible for complex functions like
intersensory association, memory and
communication.
D. It is a part of cerebral cortex.
1. A & B
