Which of the following secrets leutenizing hormone

Options

A. Adenohypophysis
B. Corpus luteum
C. Neurohypophysis
D. Pars nervosa

Answer

To solve the question "Which of the following secretes luteinizing hormone?" we need to analyze the options provided:

1. **Adenohypophysis**: This is the anterior pituitary gland. The anterior pituitary is known to secrete several hormones, including luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

2. **Corpus luteum**: This structure forms after ovulation from the ruptured Graafian follicle and primarily secretes progesterone, not luteinizing hormone.

3. **Neurohypophysis**: This is the posterior pituitary gland. The neurohypophysis does not secrete hormones; instead, it stores and releases hormones produced by the hypothalamus, such as oxytocin and vasopressin.

4. **Pars nervosa**: This term refers to the posterior part of the pituitary gland, which is synonymous with neurohypophysis. Like the neurohypophysis, it does not secrete hormones but stores them.

From the analysis above, we can conclude that the only option that secretes luteinizing hormone is:

**Answer: Adenohypophysis (anterior pituitary)**
