endocrinology

• The hypothalamus influences the production and release of hormones from the pituitary gland and regulates body temperature, metabolism, hunger, thirst, fatigue, and circadian rhythms.
• Thyrotropin-releasing hormone (TRH) stimulates TSH release from the anterior pituitary gland.
• The posterior pituitary gland secretes oxytocin and antidiuretic hormone.
• The anterior pituitary gland is responsible for the secretion of growth hormone (GH), prolactin, adrenocorticotropic hormone (ACTH), follicle-stimulating hormone (FSH), luteinizing hormone (LH), thyroid-stimulating hormone (TSH), and melanocyte-stimulating hormone (MSH).
• The thyroid gland produces hormones that regulate metabolism and energy levels.
• The hypothalamus regulates homeostasis in the body through the release of hormones.
• Oxytocin stimulates uterine contractions during childbirth and milk ejection during breastfeeding.
• The posterior lobe (neurohypophysis) stores and releases two peptide hormones produced by the hypothalamus: oxytocin and vasopressin.
