Question

1. list each hormone secreted by the pituitary gland and a short description of what the hormone is responsible for. (we did this in your notes.)hormone from pituitary | function--- | ---8. what are the hormones secreted by the thyroid and what is their function?hormone from thyroid | function--- | ---9. what hormones are secreted by the adrenal medulla and what are they responsible for?10. where is the pineal gland located and what is it responsible for? what hormone?11. where is the thymus gland located and what is it responsible for? why is it larger in children than in adults?12. what are the two different reproductive glands? what do each produce?

Explanation:

For Question 7:

Pituitary hormones are split into anterior and posterior lobe secretions, each with distinct regulatory functions.

For Question 8:

Thyroid hormones regulate metabolism, while calcitonin manages blood calcium levels.

For Question 9:

Adrenal medulla hormones trigger the body's fight-or-flight response.

For Question 10:

The pineal gland is a small brain structure tied to circadian rhythms.

For Question 11:

The thymus supports immune development, which is critical in childhood.

For Question 12:

Reproductive glands are sex-specific and produce gametes + sex hormones.

Answer:

7.

Hormone from Pituitary	Function
Thyroid-Stimulating Hormone (TSH)	Stimulates thyroid hormone release
Adrenocorticotropic Hormone (ACTH)	Triggers adrenal cortex hormone secretion
Follicle-Stimulating Hormone (FSH)	Regulates gamete production & sex hormone release
Luteinizing Hormone (LH)	Induces ovulation/testosterone production
Prolactin (PRL)	Stimulates milk production in mammary glands
Antidiuretic Hormone (ADH)	Regulates water retention in kidneys
Oxytocin	Stimulates uterine contractions & milk ejection

8.

Hormone from Thyroid	Function
Calcitonin	Lowers blood calcium levels by inhibiting bone breakdown

9.
The adrenal medulla secretes epinephrine (adrenaline) and norepinephrine (noradrenaline). These hormones trigger the fight-or-flight response: increasing heart rate, blood pressure, and blood glucose, and directing blood flow to muscles and the brain.

10.
The pineal gland is located deep in the brain, near the center of the cerebrum. It is responsible for regulating circadian (sleep-wake) rhythms, and it secretes the hormone melatonin, which promotes sleepiness and synchronizes the body's internal clock with light-dark cycles.

11.
The thymus gland is located in the upper chest, behind the sternum and between the lungs. It is responsible for maturing T-lymphocytes (a type of white blood cell) that are critical for adaptive immune function. It is larger in children because childhood is a key period for developing and establishing a robust immune system; it shrinks in adulthood as immune development is mostly complete, and its tissue is gradually replaced by fat.

12.
The two main reproductive glands are:

1. Testes (male): Produce sperm (male gametes) and the sex hormone testosterone, which regulates male secondary sexual characteristics and reproductive function.
2. Ovaries (female): Produce ova (female gametes, or eggs) and the sex hormones estrogen and progesterone, which regulate the menstrual cycle, female secondary sexual characteristics, and support pregnancy.
