my own stack endocrine system and special senses
| Question | Answer |
|---|---|
| Prolactin,TSH, LH, GH, ACH, FSH | all secreted from the posterior pituitary gland |
| glycogenolysis | Breakdown of glycogen into glucose |
| weight gain, mental, slowness, lethargy, bradycardia, constipation | all symtoms of Thyroid hormone deficiency |
| increased basal metabolic rate, hair loss, good appetite, exopthalmos | all symptoms of excess thyroid hormone |
| glucocorticoids | stress causes their release, they stimulate gluconeogenesis, they are hyperglycaemic |
| glycogenesis | formation of glycogen from glucose |
| gluconeogenesis | formation of new glucose from non-sugar molecules |
| mineralcorticoids | they regulate or influence the sodium, potassium, and hydrogen balance, and are made and secreted from the adrenal cortex |
| angiotensin 2 | stimulates adrenals to secrete aldosterone |
| net effect of aldosterone secretion | increases urine output and sodium output |
| Renin converts | Angiotensin 2 to angiotensin 1 |
| low blood sugar volume | stimulates secretion of Renin |
| ACE | hormones made by the lungs |
| Antidiuretic hormone, and oxytocin | made and secreted by the anterior pituitary gland |
| hypoglycaemia | low blood sugar levels |
| hyperglycaemia | high blood sugar levels |
| What controls the amount of light that get in the eyes? | constriction of the pupils |
| this causes the most significant bending of light waves | the lens of the eye |
| Refraction | When light waves pass from a medium of one density to another they bend |
| Have the shortest wavelength | violet light waves |
| speed of light | 300,000 kilometer per second |
| cochlear duct | this structure is outside the vestibule of the inner ear,and is concerned with hearing |
| function of the utricle, and saccule | detecting the position of the head |
| components of the external ear | auricle, cerumen secreting gland, external auditory meatus |
| 1.tympanic membrane 2.hammer, 3.anvil, 4. stirrup 5.oval window | order of sound waves across the middle ear. |
| where is the organ of corti located | coclear duct |
| parts of bony labyrinth | semicircular canal, vestibule, cochlea |
| how many openings are there into the middle ear? | 4 |
| Trophic hormones | target other endocrine glands and stimulate their growth and secretion |
| nonsteroid hormones | oxytocin, calcitonin, and glucagon |
| this gland sends a hormone to stimulate the production of the thyroid hormone | anterior pituitary gland |
| lipogenesis | synthesis and storage of fatty acids |
| this secretes aldosterone (epinephrine) | adrenal medulla |
| FSH | follicle stimulating hormone, causes growth of the ovarian follicle |
| prolactin | helps with milk production |
| link between the hypothalmus, and adenohypophysis | hypophyseal portal system |
| lipid base hormones | oestrogen, testosterone, thyroxine, progesterone, aldosterone |
| peptide hormones | insulin, adrenoline, noradrenaline, glugacon |
| Thymosin | plays role in immunity |
| pancreas | serves both as an exocrine and endocrine capacity |
| histamine | broncoconstrictor, released as a part of the inflammatory response |
| Renin is made by: | kidney |
| lipolysis | breakdown of fats |
| Reabsorption of sodium and water by the kidney tubules is caused by an increase of: | Aldosterone |
| Aldosterone | is a mineralcorticoid secreted by the adrenal cortex |
| Serotonin | a hormone present in platelets |
| secretion of aldosterone controlled by | Renin-angiotensin-aldosterone mechanism: blood potassium concentration |
| What causes near vision to occur | increased curvature of the lens |
| prostaglandins | involved in blood clotting |
| inflammatory response | involves both histamines and prostaglandins |
| Endocrine glands have | higher than normal blood supply |
| functions of endocrine system | control, integration and communication |
| where is the nervous tissue of the eye found | retina |
| Where are the blood vessels in the eye? | choroid |
| serves as storage and release site for antidiuretic hormone and oxytocin | neurohypophysis |
