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 |
Depolarization of axolemma during nerve conduction takes place because of:
1. | Equal amount of Na+ & K+ moves out across axolemma |
2. | Na+ ions move inside |
3. | More Na+ ions are outside |
4. | None of the above |
The limbic system is formed by

2. Hypothalamus, amygdala and hippocampus
3. Corpora quadrigemina and hippocampus
4. Midbrain an hindbrain
Highly vascular and closely investing protective coat around the brain is known as
1. Arachnoid
2. Pia mater
3. Dura mater
4. Sub-arachnoid space
During the process of impulse conduction, the depolarisation of axon takes place because
1. Voltage gated channels open
2. Equal amounts of and are pumped out
3. Voltage gated channels open
4. Equal amounts of and K are pumped in
Hypothalamus does not contain centre for controlling
1. Body temperature
2. Hunger
3. Respiration
4. Osmoregulation
Read the following statements
(A) | Depolarization of an axonal membrane is caused due to rise in stimulus-induced permeability to Na+ and its rapid influx into axoplasm. |
(B) | Diffusion of K+ outside the axonal membrane restores the resting potential of the membrane. |
(C) | Sodium potassium pump maintains active transport of 2Na+ outwards for 3K+ into axoplasm across resting membrane |
