Question

Which of the following pairs of structures have similarity of function?
A. Adrenal cortex and sympathetic nervous system
B. Adrenal cortex and parasympathetic nervous system
C. Adrenal medulla and parasympathetic nervous system
D. Adrenal medulla and sympathetic nervous system​

Answer 1

Explanation:

In the above question, we need to identify the pairs which are very similar in function. So, let's see the options and identify theses pairs.

The Adrenal medulla is the modified form of a sympathetic ganglion. Adrenal medulla is the inner portion of adrenal gland. It releases the Epinephrine and Non-epinephrine. They are the emergency hormones.

The Adrenal medulla releases these hormones into the blood by recieving a simulation from the sympathetic nervous system.

Functionally:

Sympathetic nervous system:-

• Involve fight and flight response.
• Prepares the body from outside danger.
• The time of response is faster.
• Increases heart beat.
• The pupil dilates.
• Stimulate to release adrenaline.
• More glycogen converts into glucose.

Adrenal medulla:-

• Released during fight and fright response.
• Increases heart rate and blood pumping.
• Dilates the pupil.
• Increase blood sugar level to give energy etc.

So, most of the functions are matching and similar to each other. Hence, the Correct Option is:

And we are done !!
