Endocrine System: Hypothalamus

The endocrine system is a complex network of glands and hormones essential for regulating various bodily functions. The hypothalamus plays a pivotal role by releasing hormones like GnRH, CRH, TRH, PRH, and GHRH, which influence the pituitary gland.

Endocrine System:

Hypothalamus

Thymus Gland

Thymosin

T-cell production stimulation

Pineal Gland

Melatonin

sleep cycles

Pancreas

Islet of Langerhans

Glucagon
liver converts glycogen to glucose
Insulin
Drives glucose into cells

Abbreviation Key GnRH: gonadotropin-releasing hormone CRH: corticotropin-releasing hormone TRH: thyrotropin-releasing hormone PRH: prolactin-releasing hormone GHRH: growth hormone-releasing hormone LH: luteinizing hormone PL: prolaction FSH: follicle-stimulating hormone ACTH: Adrenocorticotropic hormone GH: growth hormone TSH: thyroid-stimulating hormone T3: triiodothyronine T4: thyroxine PTH: parathyroid hormone
