What is the function of Oxytocin hormone?
Options
- AStimulation of water and electrolyte resorption
- BStimulation of contraction of uterus and milk ejection
- CStimulation of growth hormone secretion
- DStimulation of steroid hormone secretion
Correct answer
B. Stimulation of contraction of uterus and milk ejection
Step-by-step solution
FSH stimulates growth and development of the ovarian follicles in females. MSH acts on the melanocytes (melanin containing cells) and regulates pigmentation of the skin. Oxytocin acts on the smooth muscles of our body and stimulates their contraction. In females, it stimulates a vigorous contraction of uterus at the time of child birth, and milk ejection from the mammary gland. Vasopressin acts mainly at the kidney and stimulates resorption of water and electrolytes by the distal tubules and thereby reduces loss of
