Explanation / Answer

16.B

Sella turcica is a depression on the superior(upper) surface of sphenoid bone. This is where the pituitary gland is located.

17.B

Homeostasis: Origin greek. 'Homoios' same and 'Stasis' standing still, state.

Thus homeostasis is the property by which a body/system /cell seeks to maintain or maintains a state of equilibrium within its internal environment inspite of external changes. Thus the maintenance of body temperature in humans to 37 degree Celsius is a mechanism by which the body is seeking to maintain equilibrium. Therefore the correct answer is 'B'.

18.B

The cervical vertebrae alone have 2 transverse foramina (openings) called as 'transverse foramina'. This is the distinguishing feature of cervical vertebrae given in the options.
