Answer each question with a brief explanation.

Answer 1

Option a is wrong as amygdala will not secrete a specific hormone that will help in the induction and maintaining of sleep

Option b is the answer as melatonin is the main hormone that regualte the circadian rhythm . This hormone is produced from aminoacid trptophan . This process takes place in the pineal gland and so dysfunction of this hormone from the pineal gland is the main cause of sleep deprivation.

Option c is wrong as thalamus usually will not secrete hormone and has no function in the circadian rhythm control

Option d is wrong as hormone balance of circadian rhythm is not a function of pons
