Thalumus
All sensory information is relayed from the?
stress
hypothalumus responds to?
fight or flight
hypothalumus has one response and that is?
epinephrine
whats the hormone that responds to fight or flight?
sodium, glucose in the blood
Cells of adrenal cortex secrets hormones that influence?
good, because hormones are realeased into your blood stream
does endocrine glands have a good or bad blood suply? why?
hypothalumus, adenohypohesis
hypophiseal protal veins connect the capillary bed of the ___________ with the capillary bed of the _____________
T3 and T4
follicle cells release what hormones?
protein synthasis
T3 and T4 help regulate?
basic metablolic rate
protein synthasis is all about?
signal from the hypothalumus
how does the anterior patuitary know to release TSH (thyroid stimulating hormone)
basic metabolic rate

(LH) Luteinizing hormone
mammary glands
(PRL) prolactin
adrenal cortex

1. signals from the nervous system
2. chemical changes in the blood
3. and other hormones
Hormone secretion is regulated by
1.
2.
3.
1. cardiac conduction
2. atrioventricular bundle-bundle of fibers that carry cardiac impulses
3. atrioventricular node- a section of the nodel tissue that delays and relays cardiac impulses
4. purkinje fibers- fiber branches that extend from the atriovenricular bundle
5. sinoatrial node- A section of the nodal tissue that sets the rate of contraction for the heart
1. This is the rate at which the heart conducts electrical impulses: (2-5) the following structures play an important role in causeing the heart to conduct. (List functions too)
Respiratory pump mechanism
Pressure changes occur in the thoracic and abdominal cavities during inspiration and expiration. This compresses veins and assists blood return to the heart.
The muscle pump mechanism
Muscular contractions compress the veins, squeezing blood back towards the heart.
diastole phase- the heart ventricles are relaxed and heart fills with blood.
systole phase- heart ventricles contract and pump blood to artaries
The sequence of events that occurs when the heart beats. (2) list functions
