What do we call the products of the endocrine gland?
What part of the brain is the master control center of the endocrine system?
What two hormones does the hypothalamus produce?
- antidiuretic hormones
- - reabsorption of water, elevate BP
- oxytocin-labor contractions, milk ejection
What endocrine gland is found in the sella turcica of the spehnoid bone and cosists of two lobes?
Provide the technical name for the
- posterior lobe
- anterior lobe
Neurohypophysis : Posterior lobe
Adenohypophysis: Anterior lobe
What two hormones are distributed from the posterior lobe?
Antidiuretics and oxytocin
What hormones are secreted by the anterior lobe?
- 1. Thyroid stimulating hormones
- 2. Adrenocorticotropic
- 3. Follicle stimulating hormone
- 4. Luteinizing hormone
- 5. Prolactin
- 6. Growth hormone
- 7. Melanocyte stimulating hormone
Thyroid stimulating hormone
release of thyroid hormones
release of steroids from adrenal cortex
Follicle stimulating hormone
Oocyte development and estrogen producing/ sperm production
Ovulation and progestin production/ androgen production
Milk production and mammary gland development
Accerelate protein production
Melanocyte stimulating hormone
What bi-lobed endocrine gland is located anterior to the trachea just inferior to the larynx?
What hormone is secreted by the thyroid gland?
- Triiodothyronine and Thyroxine
Triiodothyronine and Thyroxine
increase cellular metabolism
decrease blood calcium levels
What endocrine glands are located on the posterior aspect of the thyroid gland?
What hormone increases blood calcium levels? (released by the parathyroid gland)
What two layered endocrine glands are located on the superior border of each kidney?
What layer is yellow because of the presence of stored lipids? (on the adrenal gland)
What is the general term for the hormones secreted from the adrenal cortex?
Name 3 types of corticosteroids
- 1. mineralcorticoids
- 2. glucocorticoids
- 3. androgen
conservation of sodium and water
in women promote muscle mass/ libido
What layer, on the inside of the adrenal gland, is composed of modified ganglionic neurons?
What two hormones, secreted by the adrenal medullar, produce effects similar to the sympathetic stimulation?
Epinephrine and norepinephrine
What mixed gland lies deep to the stimach between the C of the duodenum and the spleen?
What two hormones produced by the pancrea are most directly involved with the regulation of blood glucose levels?
alpha cells, increase blood glucose levels
beta cells, decrease blood glucose levels
What form of diabetes, linked to the pancreas, is associated with glucose levels so high that our kidneys cannot reabsorb all of it?
What form of diabetes is not linked to the pancrea at all but rather the lack of anti-diuretic hormones from the posterior pituitary?
What endocrine gland is located deep to the sternum and regresses with age after puberty?
What category of hormones, produces by the thymus, assists in the maturation and fuction of the immune system?
What is the name of the male gonads?
What is the primary androgen, produced by the testes, that promotes skeetal muscle growth and male secondary sexual characteristics?
What is the name of the female gonads?
What is the general term for the hormones that support follicle maturation and growth of the uterine lining as well as producing female secondary sexual characteristics?
What is the general term for the hormones produced by the corpus luteum that causes the uterus to prepare for implantation?
What small endocrine gland is located on the posterior aspect of the diencephalon of the brain?
What hormone, produced by the pineal gland, regulates circardian rhythms and the onset of sexual maturity?
