Pituitary gland and thyroid gland?

Pituitary Gland

- Location: Base of the brain (hypothalamus)
- Function: Master endocrine gland that controls other endocrine glands through hormone release
- Hormones secreted:
- Growth hormone (GH)
- Adrenocorticotropic hormone (ACTH)
- Thyroid-stimulating hormone (TSH)
- Follicle-stimulating hormone (FSH)
- Luteinizing hormone (LH)
- Prolactin
- Regulation: Hypothalamic releasing and inhibiting hormones

Thyroid Gland

- Location: Neck, below the larynx
- Function: Regulates metabolism and growth
- Hormones secreted:
- Thyroxine (T4)
- Triiodothyronine (T3)
- Regulation: TSH from the pituitary gland

Relationship between Pituitary and Thyroid Glands

- The pituitary gland releases TSH, which stimulates the thyroid gland to secrete T4 and T3.
- T4 and T3 in turn provide negative feedback to the pituitary gland, inhibiting TSH secretion.
- This negative feedback loop regulates thyroid hormone levels in the body.
