-
Paracrine signal
-
Autocrine signal
-
Endocrine signal
-
Synaptic signal
C
Correct answer
Explanation
Endocrine signals are called hormones. Hormones are produced by endocrine cells and they travel through the blood to reach all parts of the body.
-
adrenaline
-
non-adreanline
-
thyroxine
-
thymosin
D
Correct answer
Explanation
Thymosin is the hormone secreted by the thymus gland that stimulates the maturation and differentiation of T-lymphocytes. The thymus is the primary lymphoid organ where T-cells develop their antigen-specific receptors during fetal development.
-
More of testosterone is produced
-
Less of testosterone is produced
-
There is no effect on the production of testosterone
-
Sperm production will increase
A
Correct answer
Explanation
Luteinising hormone (LH) stimulates the Leydig cells in the testes to produce testosterone. In males, LH is the primary regulator of testosterone synthesis. When exogenous LH is administered, it will stimulate increased testosterone production by these cells. LH does not directly stimulate sperm production - that's the role of FSH.
