Hondros A&P 2 final
chemical messengers –
Endocrine system makes use of hormones
Pituitary hypthal, pineal, thyroid, thymus adreneal, testes&ovaries –
Parts of the endocrine glands
Non steroid(protein hormones) and steroid hormones –
2 major groups of hormones
sex hormones, Cortisol –
Steroid hormones bind to receptors without nucleus
Insulin, epinephrine –
Non steroid hormones bind to receptors on cell membrane
Action of Insulin –
lowers BG level in the pancreas
Action of glucagon –
raises BG level
where is Cortisol(stress hormone) produced? –
Adrenal cortex
Epinephrine produced by? –
Adrenal medulla (fight or flight)
Cortisol has what to do with Addison's disease? –
not enough Cortisol
Cortisol has what to do with crushing disease? –
too much Cortisol
what is the thyroid hormone produced by? –
thyroid metabolic rate
S/S of hypothyroidism –
weight gain
S/S of hyperthyroidism –
weight loss
, TSH stimulates what? –
the thyroid to produce Thyroid hormones (T3,T4)
Hypersecretion –
increased metabolic rate, inability to gain weight, nervousness
Hyposecretion –
low energy, weight gain
Functions of Cortisol –
resistance to stress, inhibits inflammation and immunity, rasies BG levels
Arteries –
carries blood away from the heart
Veins –
carries blood toward the heart
Valves that produce the "lub" –
(AV-valves) tricuspid & bicuspid
Valves that produce the "dub" –
(Semilunar valves) pulmonary and aortic valves
All arteries carry oxygenated except for –
Pulmonary artery
All veins carry deoxygenated blood except for –
Pulmonary vein
P wave –
atrial depolarization
QRS wave –
ventricular depolarization
T wave –
ventricular repolarization
Atrial systole –
depolarization
Pace maker of the heart –
SA node
Effects of sympathetic side –
