Explanation / Answer
as.1)d- anterior pituitory
reason- long term negative feedback is given by T3 and T4 to both pituitory gland and hypothalamus. but short loop is given by anterior pituitory to hypothalamus
ans.2)e- melatonin
reason- melatonin is secreted by pineal gland and is responsible for circadian rhythm
ans.3)c- increased mobilisation of fuel sources
reason- to increase energy level to compensate stress on body including activation of sympathetic nervous system
ans. 4 ) c. Primary hyposecretion disorder
reason- the tumor is not letting thyroid to secrete normal levels of hormone
