Endocrine Gland Locations Flashcards
Exocrine
Glands that screte their products into ducts
Lacrimal glands, sweat glands, salivary glands, liver and pancreas
Endocrine
Directly into the blood stream
Produce hromones that produce their effects upon target organs
Pituitary Glands
Master Gland
Controls the activity of several tissues
Housed within the sella turcica of the sphenoid bone of the skull
Hypothalamus
Controls the pituitary glands by its releasing factors
Nine hormones of the Pituitary gland
Melanocytes stimulating hormone Growth hormon Antidiuretic hormone Prolactin Oxytocin Thyroid stimulating hormone Adrenocorticotrophic hormone Follicle stimulating hormone Luteinzing hormone
Melanocytes stimulating hormone
Activates the melanocytes found within the dermis of the skin
Growth hormone
Promotes expansion of the issue mass within the bones and skeletal muscles
Antidiuretic hormone
Stimulates the kidney to reabsorb water from the urine
Prolactin and Oxytocin
Acts on breast tissue promoting milk production and release respectively
Thyroid stimulating hormone
Activates thyroid gland
Thyroid gland
Control the rate of metabolic activity
Parathyroid glands
Release parathyroid hormone, serving to regulate calciuma nd phosphate concertrations in the bloodstream and skeleton.
CANNOT BE REMOVED
Adrenocorticotrophic Hormone
Stimulates the cortex of the adrenal glands
Adrenal Glands
Release various corticoids that regulate electrolytes, food metabolism and sexual activity.
Adrenal Cortex
Releases corticoids under the influence of the pituitary gland
Adrenal Medulla
Stimulated by the sympathetic nervous system to release epinephrine and norepinephrine
Follicle Stimulating Hormone (Female)
Acts upon the ovaries in females
Stimulates follicle development and production of estrogens and progesterone
Lutenizing Hormone (Female)
Prompts ovulation and the development of the corpus luteum
Follicle Stimulating Hormone (Male)
acts upon the sertoli cells, as well as developing spermatozoa in the seminiferous tubules
Lutenizing Hormone (Male)
interstital cell stimulating hormone
Acts upon the intersitial cells fo leydig to stimulate the release of tesosterone
Pineal Gland
Located posterior to the thalamus and hypthalamus
Responsible for the nocturnal release of melatonin and daytime secretion of serotonin
Controlled by the hypothalamus in response to light enetering the eyes
Melatonin
Regulator role in sexual and repoductive functions and sleep
Thymus Gland
Located over heart
Obtains max size and function prior to puberty
Goes away after puberty
Secrete thymosin
Thymosin
activates thymic lymphocytes (T-cells) that originate in the bone marrorw
