Neurosecretory cells
|
Specialized nerve cells that release hormones into the blood via the extracellular fluid
|
Cytokine
|
Peptide/protein local regulator that plays a role in immune responses
|
Nitric oxide
|
Local regulators. improves blood flow to tissues, is neurotrans in nervous sy, and in immune sy, kills bacteria and cancer cells in body fluids
|
Prostaglandins
|
Local regulator. causes uterus wall to contract, inducing fever and inflammation and intensifying pain.
|
Oxytocin
|
Posterior pit. stimulates contraction of uterus and mammary gland cells
|
Antidiuretic hormone
|
Posterior pit. acts on kidneys, increases water retention
|
Tropic hormones of anterior pituitary gland
|
Follicle-stimulating hormones, luteinizing hormone, thyroid-stimulating hormones, adrenocorticotropic hormone
|
Gonadotropins
|
Fsh and lh. trpic hormone of anterior pit. stimulate activities of male and female gonads
|
Thyroid-stimulating hormones (TSH)
|
Trpic hormone of anterior pit. promote normal development of the thyroid gland and the production of thyroid hormones
|
Adrenocorticotropic hormone (ACTH)
|
Trpic hormone of anterior pit. stimulates production and secretion of steroid hormones by adrenal cortex
|
Nontropic hormones of anterior pituitary
|
Prolactin, melanocyte-stimulating hormone, b-endorphin
|
Prolactin (PRL)
|
Nontrpic hormone of ant. stimulates mammary gland growth & milk synthesis in mamms, regulates fat production in birds, metamorph in amphibs
|
Melanocyte-stimulating hormone (MSH)
|
Nontrpic hormone of ant. regulates activity of pigment-containing cells in the skin of some fishes, amphibs, and repts. inhibits hunger in mamms
|
B-endorphins
|
Nontrpc hormone of ant. dulls perception of pain
|
Growth hormone (GH)
|
Ant. signals liver to release insulin-like growth factors which stimulate bone and cartilage growth
