Solutions

4. The correct answer is Option C – FSH

FSH stands for follicle –stimulating hormone. It is produced by the pituitary gland at sexual maturity in females. It is chiefly responsible for the development of primordial follicles, which leads to development into oocyte.

LH (Leutenizing hormone) is a mid-cycle pituitary hormone that promotes ovulation.
Prolactin is a pituitary hormone that promotes lactation in response to the suckling stimulus.
ACTH (Adreno cortico tropic hormone) is a hormone secreted by the anterior pituitary to regulate levels of the steroid hormone cortisol.

5. The correct answer is Option B – Penile Erection

Erection is basically a spinal reflex initiated by afferent nervous system. It is not directly affected by gonadotropic hormones. The molecules which affect penile erection are Dopamine, acetylcholine, nitric oxide (NO), and peptides, such as oxytocin and adrenocorticotropin/?-melanocyte-stimulating hormone.
