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

hypothalumus has contorl over?

A buffer

limits the potential change in PH is called?

Melonocyte (MSH)

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
