Endocrine (Chapter 16) Flashcards
Secretes hormones into the bloodstream
Endocrine System
A chemical messenger secreted into the blood that triggers changes with in its target cells
Hormones
Master gland, takes stimulation from the hypothalamus (control center) and directs it to all the other endocrine glands
Pituitary Gland
Regulates metabolism through the hormones (T3 and T4)
Thyroid Gland
Regulates the body blood calcium levels through the parathyroid hormone. (muscle contraction, bone growth,etc)
Parathyroid Gland
Is where the adrenal corticosteroids (cortisol and aldosterone) are made,
Adrenal Cortex (outer)
Is where the adrenal catecholamines (epinephrine and norepinephrine) are made, fight or flight hormones.
Adrenal Medulla (inner)
Secretes sex hormones progesterone and estrogen in females and testosterone in males.
Gonads (Ovaries and Testes)
Stimulates blood sugar with the hormones insulin and glucagon
Pancreas
Function at the cell that makes them
Autocrine hormones
Function regionally.
Paracrine hormones
Function at a distance.
Endocrine hormones
Small anteroinferior portion of the diencephalon of the brain that transports neural signals from the brain to the pituitary gland.
Hypothalamus
Also called the hypophysis
Pituitary Gland
Connects the hypothalamus to the pituitary gland
Infundibulum
Also called adenohypophysis
Anterior pituitary gland
Also called neurohypophysis
Posterior pituitary gland
A hypothalamic hormone that control water balance
Antidiuretic Hormone (ADH)
A hypothalamic hormone that support reproduction and milk release
Oxytocin
Stimulate or inhibit the release of hormones from the anterior pituitary gland.
Releasing and Inhibiting Hormones
Anterior pituitary hormone that stimulates the production and release of thyroid hormone and growth of the thyroid gland.
Thyroid-stimulating hormone (TSH)
Anterior pituitary hormone that is released by the adrenal cortex that stimulates the production of mostly glucocorticoids from the adrenal cortex.
Adrenocorticotropic hormone (ACTH)
Hormones produced by the anterior pituitary gland that stimulates reproductive functions in males and females.
Luteinizing Hormone (LH)
Hormone produced by the anterior pituitary gland that stimulates reproductive functions in males and females.
Follicle-stimulating Hormone
A hormone produced by the anterior pituitary gland that stimulates the growth of the mammary gland, initial of milk production after childbirth, and the maintenance of milk production for the duration of breastfeeding.
Prolactin (PRL)
Stimulate male and female gonads to produce testosterone in males and estrogen and progesterone in females
Gonadotropin-releasing hormone (GnRH)
A hormone produced by the anterior pituitary gland that promotes fat breakdown and gluconeogenesis, also stimulates the release of insulin-like growth factor, which promotes growth and protein synthesis.
Growth hormone (GH)
Connects the right and left lobes of the thyroid gland
Isthmus
