Table 11-1 from G&F: KNOW THIS! Flashcards
What are the 7 main Gland categories in Table 11-1?
(and sub gland categories if you want)
- Pituitary
- Anterior lobe
- Posterior lobe
- Thyroid
- Parathyroids
- Adrenal
- Cortex
- Medulla
- Pancreas
- Gonads
- Ovaries
- Testes
- Adipose Tissue (I believe it is a typo in the chart that this is listed under gonads based on reading the text on pg 456 which says “Adipose tissue can be classified as an endocrine gland because it secretes several hormones responsible for metabolism, hunger, vasoconstriction, and cellular growth and development. The concept of adipose tissue as an endocrine organ is quite new, but it is clear that molecules secreted into the bloodstreeam by fat, such as adiponectin and leptin, act on target organs at distant sites.”) Also, since when has Adipose tissue been exclusive to gonads?
What are the two sub-divisions of the Pituitary gland?
- Anterior lobe
- Posterior lobe
What are the 6 hormones of the Anterior Pituitary lobe?
- Somatotropin (growth hormone [GH])
- Thyroid-stimulating hormone (TSH)
- Follicle-stimulating hormone (FSH)
- Luteinizing hormone (LH)
- Prolactin (luteotropic hormone)
- Adrenocorticotropic hormone (ACTH)
What is an alternate name for growth hormone?
Somatotropin
What is an alternate name for prolactin?
luteotropic hormone
Somatotropin target tissues (3)
- Bones
- Muscles
- Organs
**Somatotropin = Growth Hormone
Basic action of somatotropin
Retains nitrogen to promote protein anabolism (basically causes growth)
*Somatatropin = Growth hormone
**Anabolism = the constructive phase of metabolism, in which the body cells synthesize protoplasm for growth and repair; the opposite of catabolism.(http://medical-dictionary.thefreedictionary.com/anabolism)
Target of TSH
Thyroid gland
(TSH = Thyroid stimulating hormone)
Basic Action of TSH
Promotes secretory activity
(I think this means it promotes secretion of hormones in thyroid: thyroxine (T4), triiodothyronin (T3) and also Calcitonin)
FSH Target tissues (2)
- Ovaries,
- Seminiferous tubules (located in testes)
FSH Basic Action (3)
Promotes
- development of overian follicle,
- secretion of estrogen, and
- maturation of sperm
Prolactin Target Tissues (2)
- Corpus Luteum
- Breast
**Prolactin = luteotropic hormone
***The corpus luteum is a temporary endocrine structure involved in ovulation and early pregnancy. The corpus luteum develops from an ovarian follicle during the luteal phase of the menstrual cycle or oestrous cycle, following the release of a secondary oocyte from the follicle during ovulation. (wikipedia and radiopaedia.org)
Prolactin Basic Action (3)
- Maintains corpus luteum and
- maintains progesterone sectretion
- stimulates milk secretion
Prolactin = luteotropic hormone
ACTH Target
Adrenal cortex
(cortex of the adrenal gland)
ACTH Basic Action
Stimulates secretory activity [of the adrenal cortex]
**Adrenal cortex produces mineralocoricoids [aldosterone], glucocorticoids [cortisol], and sex hormone [testosterone, estrogen, progesterone]
What are the two hormones of the posterior lobe of the pituitary gland?
- antidiuretic hormone (ADH)
- Oxytocin
ADH Target tissue
Distal tubules of kidney
ADH Basic Action
Resorbs water (into the distal tubules of the kidney - therefore it prevents water loss from the body)
Oxytocin Target Tissue
Uterus
Oxytocin Basic Action
Stimulates contraction (of the uterus)
What are the 2-3 hormones of the thyroid gland?
- Thyroxine (T4) and Triiodothyronine (T3)
- Calcitonin
Thyroxine (T4) and Triiodothyronine (T3) target tissues
Widespread
Thyroxine (T4) and Triiodothyronine (T3) Basic Action (5-8)
- Regulate
- oxidation of body cells and
- growth metaboilism
- influlence
- gluconeogenisis, (creation of new glucose)
- mobilization of fats, and
- exchange of
- water,
- electrolytes, and
- protein
Calcitonin Target
Skeleton
Calcitonin Basic Action (2?)
Calcium and phosphorus metabolism
(encourages lowering Ca2+ levels in the blood, which preserves Ca2+ in the bone)
What are the hormones of the parathyroid glands?
Parathyroid hormone (PH)
Parathyroid Hormone Target (3)
- Bone
- Kidney
- Intestinal tract
Parathyroid hormone Basic Action (1-3?)
Essential for calcium and phoshorus metabolism and calcification of bone.
(incourages Ca2+ levels in the blood by encouraging relase of Ca2+ from the bone, which may reduce Ca2+ in the bone)
What are the two main portions of the Adrenal gland?
- Cortex
- Medulla
What are the three categories of hormones relased by the Adrenal Cortex
- Mineralocorticoids (main example aldosterone)
- Glucocorticoids (main example cortisol)
- Sex hormones (testosterone, estrogen, progesterone)
What is the main example of a mineralocorticoid?
Aldosterone
What is the main example of a glucocorticoid?
Cortisol
What are three sex hormones secreted by the Adrenal Cortex?
Testosterone
Estrogen
Progesterone
Mineralocorticoids Target
Mineralocorticoids, such as Aldosterone
- Widespread, primarily kidney
What is another name for ADH?
Vasopressin
Mineralcorticoid Basic Action
Aldosterone, as the main Mineralcorticoid:
- Maintains fluid/electrolyte balance; reabsorbs sodium chloride; secretes potassium [from the body]
- (water goes where salt [sodium chloride] goes,so it causes fluid retension(
- It increases BP by increasing blood volume through fluid retension.
Glucocorticoid Target
(Cortisol was the example)
Widespread
Glucocorticoid Target (5)
Cortisol was the example
- Concerned with food metabolism and body response to stress
- Preserves carbohydrates and
- mobilizes amino acids
- Promotes gluconeogenesis
- suppresses inflammation
*mobilizing amino acids usualy means breakdown of protein
**gluconeogenesis means creating new glucose
Sex hormones from the Adrenal Cortex: what is the target?
Gonads
Sex hormones from the Adrenal Cortex: What is the basic action?
ability to influence secondary sex characteristics
What are 2 hormones from the Adrenal Medulla
Epinephrine
Norepinepherine
**even though it seems like nor-epinepherine would mean non-epinepherine or anti-epinephrine, this is not true. They actually usually work together.
What is another name for epinephrine?
Adrenaline
Epinephrine Target
Widespread
Epinephrine Basic Action (6)
- Cardiac:
- myocardial stimulation
- tachycardia
- dysrhythmias
- vasoconstriction with increased BP
- increased blood glucose via glycolysis
- stimulates ACTH production
(in general promotes sympathetic NS)
norepinephrine target
widespread
norepinephrine basic action
vasoconstriction
What are two hormones of the pancreas?
Insulin
Glucagon
Insulin Target
widespread
Insulin Basic action
increased utilization of carbohydrate; decreased blood glucose
(allows blood glucose into cells for use as energy)
decreases blood glucose level (opposite of Glucagon)
Glucagon Target
widespread
Glucagon Basic Action
Hyperglycemic factor; increases blood glucose via glycogenolysis
(basically breaks down carbohydrates into glucose so they can enter the blood stream)
Increases blood glucose level (opposite of Insulin)
What are the 2 subdivisions listed under Gonads?
- Ovaries
- Testes
*** The chart also appears to list Adipose Tissue under gonads, but I believe it is a typo and was meant to be listed as a seperate category in the chart that this is listed under gonads. I think this based on reading the text on pg 456 which says “Adipose tissue can be classified as an endocrine gland because it secretes several hormones responsible for metabolism, hunger, vasoconstriction, and cellular growth and development. The concept of adipose tissue as an endocrine organ is quite new, but it is clear that molecules secreted into the bloodstreeam by fat, such as adiponectin and leptin, act on target organs at distant sites.” Plus, since when was Adipose tissue a type of gonad? ><
