Single Choice

Select the option that correctly matches the structures with its location and function.

AStructure - Eustachian tube, Location - Anterior part of internal ear, Function - Equalises air pressure on either sides of tympanic membrane
BStructure - Cerebellum, Location - Midbrain, Function - Controls respiration and gastric secretions.
CStructure - Hypothalamus, Location - Forebrain, Function - Controls body temperature, urge for eating and drinking
Correct Answer
DStructure - Blind spot, Location - Near the place where optic nerve leaves the eye, Function - Rods and cones are present but inactive here

Solution

A. Structure- Eustachian tube, Location- Middle ear, Function- Equalise the pressure of air on the two sides of the tympanic membrane.

B. Structure- Cerebellum, Location- Hindbrain, Function- It maintains posture, equilibrium and muscle tone.

C. Structure- Hypothalamus, Location- Forebrain, Function- It contains centres for maintaining homeostasis by regulating body temperature, heartbeat, water balance and blood pressure.

D. Structure- Blind spot, Location- Optic nerve start from this spot, Function- It lacks visual receptors and is insensitive to light.

So, the correct answer is 'Structure- Hypothalamus, Location- Forebrain, Function- Controls body temperature, urge for eating and drinking'.
