Which of the following endocrine gland releases hormone related to puberty in human females?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1: Ovary.
Explanation:
- In human females, the ovary is the primary endocrine gland and reproductive organ responsible for releasing key sex hormones during puberty.
- Key Hormones: Two major steroid hormones are secreted by the ovaries:
- Estrogen: This hormone is responsible for the development of secondary sexual characteristics in females (such as breast development, voice modulation, and the widening of the hips).
- Progesterone: This hormone primarily aids in maintaining pregnancy and regulating the menstrual cycle.
- Puberty: Typically occurring between the ages of 10 and 14, hormones released by the pituitary gland (LH and FSH) stimulate the ovaries, thereby initiating the production of these hormones.
Analysis of Other Options (Quick Revision):
- Pancreas (Option 2): This gland primarily releases the hormones insulin and glucagon, which regulate blood sugar levels within the body.
- Pineal Gland (Option 3): This gland releases the hormone melatonin, which regulates our sleep-wake cycle (Circadian Rhythm).
- Hypothalamus (Option 4): Often referred to as the 'Master of the Master Gland,' it releases regulatory hormones that control the pituitary gland.
