Q. No.Destruction of the anterior horn cells of the spinal cord would result in loss of?
1. Sensory impulses
2. Voluntary motor impulses
3. Commissural impulses
4. Integrating impulses
Which of the following regions of the brain is incorrectly paired with its function?
| 1. | Medulla oblongata-Homeostatic control |
| 2. | Cerebellum-Language comprehension |
| 3. | Corpus callosum-Communication between the left and right cerebral cortices |
| 4. | Cerebrum-Calculation and contemplation |
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

The human hindbrain comprises three parts, one of which is:
| 1. | Cerebellum | 2. | Hypothalamus |
| 3. | Spinal | 4. | Corpus callosum |
| 1. | equally permeable to both Na + and K+ ions |
| 2. | impermeable to both Na+ and K+ ions |
| 3. | comparatively more permeable to K+ ions and nearly impermeable to Na + ions |
| 4. | comparatively more permeable to Na + ions and nearly impermeable to K+ ions |
The nerve centres which control the body temperature and the urge for eating are contained in:
1. hypothalamus
2. pons
3. cerebellum
4. thalamus
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 |
