anyanavicka [17]

Answer:

Pineal gland

Explanation:

The suprachiasmatic nucleus is the paired nucleus made of about 1000 neurons each in the hypothalamus. The suprachiasmatic nucleus is involved in maintaining the endogenous clock or the internal clock.

The suprachiasmatic nucleus controls the circadian rhythm by controlling the amount of melatonin. The melatonin is produced by the pineal gland from the serotonin and tryptophan precursors.  The hypothalamus thus controls the amount of the melatonin by regulating the pineal gland.

Thus, Pineal gland is the correct answer.
