Which hormone is released during childbirth to stimulate uterine contractions?

Last Updated: 26 Jun 2026

A reliable solution begins by identifying the organ, tissue, cell, hormone, nutrient, pathogen, or biological process named in the stem and then linking it with its precise function or defining feature. Restate the question in your own words, predict the answer before checking the options, and confirm that the explanation and correct-option field both point to Oxytocin.

AOestrogen

BProgesterone

COxytocin

DProlactin

Correct Answer: OxytocinYour Answer: C

Explanation

Therefore option C, Oxytocin, is factually consistent with the stem, the marked correct index, and the explanation.✅ Correct Answer: C — Oxytocin Oxytocin is released by the Posterior Pituitary Gland during childbirth. It stimulates uterine contractions (labour pains) to facilitate delivery of the baby. After birth, oxytocin also stimulates milk ejection (let-down reflex) during breastfeeding. It is also called the 'love hormone' or 'bonding hormone' as it promotes social bonding and maternal behavior. Oestrogen — Oestrogen is the female sex hormone (produced by ovaries); prepares uterus for pregnancy but doesn't directly stimulate uterine contractions during labor. Progesterone — Progesterone maintains pregnancy and inhibits uterine contractions (opposite effect!); levels drop before labor begins. Prolactin — Prolactin (from anterior pituitary) stimulates milk production (not ejection); it doesn't stimulate uterine contractions. 📝 Important Note: Oxytocin = uterine contractions + milk ejection. Prolactin = milk production. Oxytocin is also called 'love hormone' / 'cuddle hormone'. Synthetic oxytocin (Pitocin) used medically to induce or augment labor.

Important Notes

ecord is Oxytocin, corresponding to option C. The answer field, correct index, and both explanations must remain aligned.
Read the complete stem and identify the exact demand: organ, gland, hormone, cell, tissue, nutrient, enzyme, pathogen, vector, deficiency disease, body fluid, or physiological function.
Learn endocrine facts as source–hormone–target–effect–disorder chains. Common errors arise when students confuse the gland producing a hormone with the organ affected by it.
Oestrogen, Progesterone, Prolactin are eliminated here because none satisfies the precise requirement of the stem. Practising the reason for each rejection is more reliable than memorising only the correct choice.

FAQ

SSC CGL Human Body FAQs

Common questions and clear answers for this topic.

Which body systems are most important for SSC CGL preparation?

The digestive, circulatory, nervous, and skeletal systems appear most frequently, along with sensory organs and basic endocrine functions.

How many bones are there in the human body, and is this commonly asked?

Yes, the human body has 206 bones, and questions about the largest, smallest, and total bone count appear fairly often.

What kind of blood-related questions come up in SSC CGL?

Questions usually cover blood group compatibility, the role of platelets in clotting, and basic facts about blood pressure and heart function.

Do I need detailed biochemistry knowledge for the human body section?

No, most questions focus on what each organ does and why, rather than the detailed biochemical processes behind it.

How can I retain human body facts more effectively for the exam?

Linking facts to real-life observations, like why pulse is checked at the wrist, makes them easier to recall than memorizing textbook lines.
