The Endocrine System: Anatomy and Physiology: Introduction (04:27)
The endocrine system regulates metabolic activities within the human body and moderates homeostasis by regulating the other organ systems. Hormones secreted by the endocrine system bind to cells with the appropriate receptor and relay messages to it— amino acid derivatives, peptide hormones, and lipid derivatives compose the three types of hormones present in the human body. Either a change in homeostasis or the hypothalamus prompts the endocrine system to react.
The Pituitary Gland and the Hypothalamus (04:57)
Body temperature, emotions, and sexual activity are initiated by the hypothalamus when negative feedback occurs. Located at the base of the brain, the pituitary gland regulates and controls all the cells in the endocrine system. Hormones produced by the pituitary gland include thyroid-stimulating hormone (TSH), adrenocorticotropic hormone, follicle-stimulating hormone (FSH), prolactin (PRL), luteinizing hormone, growth hormone, antidiuretic hormone (ADH), and oxytocin.
Other Endocrine Glands and Tissues: Part One (03:24)
In addition to the pituitary gland and hypothalamus, the endocrine system is comprised of the pineal gland, thyroid gland, parathyroid gland, thymus glands, and adrenal glands. Parathyroid hormone and calcitonin regulate calcium within our body.
Other Endocrine Glands and Tissues: Part Two (03:59)
Thymosins control the regulation of the immune system. Mineralocorticoids, androgens, and glucocorticoids comprise the corticosteroids. Alpha cells and beta cells on the pancreas regulate blood glucose levels.
