Positive feedback

Question 3

Name each hormone and gland involved in the secretion of the thyroid hormone cascade.

Answer 3

T4 and T3, the glands are TSH and TRH

Question 4

What hormone decreases the amount of calcium in the bloodstream?

Answer 4

Calcitonin

Question 5

This cranial nerve provides motor function on areas that include lungs, heart, and gastrointestinal track

Answer 5

Vagus

Question 6

Where is the antidiuretic hormone secreted from? What is the target tissue function?

Answer 6

ADH and the hypothalamus

Question 7

What area of the neuron is damaged?

Answer 7

Axon

Question 8

What event most directly causes an action potential calcium release in a muscle cell

Answer 8

Starts with acetylcholine

Question 9

What enzyme is used to convert co2

Answer 9

CA

Question 10

Area of the brain #3

Answer 10

Thalamus

Question 11

What receptor detects pain

Answer 11

nociceptors

Question 12

Atp had been described as the body’s energy currency. How would our body retrieve energy from atp during normal metabolism?

Answer 12

The bonds between the phosphate groups store energy. Energy can be released during metabolism by breaking high energy bonds

Question 13

What is the body’s form source of nitrogenous waste?

Answer 13

urea

Question 14

Where does the blood travel once leaving the right ventricle

Answer 14

lungs

Question 15

What ions is required for the release of neurotransmitters from the vesicles within the synaptic termina?

Answer 15

Ca, K

Question 16

what part of the nervous system does the upper motor neuron belong to?

Answer 16

CNS

Question 17

What is co2 converted into in the bloodstream? How does the conversion affect blood PH?

Answer 17

carbonic acid.

Question 18

Which is correct?

Answer 18

The femur is superior to the pelvis

Question 19

Step by step muscle contraction process

Answer 19

1.Acetylcholine is released onto the muscle cell
2.Acetylcholine causes Na channels to open in muscle cell which results in the
generation of action potential in muscle membrane
3.Action potential travels down t-tubule
4. Arrives at the sarcoplasmic reticulum, opens calcium channel
5.Calcium is put into cytoplasm where it binds to troponin
6.Troponin and tropomyosin uncoil from actin filament to expose the myosin head
7.ATP binds to myosin head allowing for myosin head to bind to myosin head binding
site
8. ATP converts into ADP+pi through hydrolysis, which allows for the myosin head to
swivel

Question 20

What is co2 converted into when it is leaving the cells and free floating in the bloodstream?

Answer 20

carbonic acid

Question 21

Function & structure of #5

Answer 21

Axon- receives signals

Question 22

Where dos co2 move to at the systemic circuit?

Answer 22

alveoli

Question 23

What component of a myocyte covers the myosin binding site on the actin filaments?

Answer 23

tropomyosin

Question 24

What main function takes place at a capillary bed?

Answer 24

gas exchange

Question 25

Where does erythropoiesis take place in the human body? what is the function? how does the kidney play a role?

Answer 25

It takes place in the bone marrow. The function is to make more red blood cells. The kidney detects the amount of oxygen in the blood. If there’s not enough it will release erythropoietin, stimulating the process of erythropoiesis.

Question 26

Identify brain area #5

Answer 26

Axon- transmit signals

Question 27

Where is water moving in a hypertonic solution? How is this related to the blood vessels?

Answer 27

water moves out. so the blood vessels will constrict

Question 28

Pacer cell purpose?

Answer 28

The purpose of pacer cells is to send out an electrical stimuli to allow for the contraction of the ventricles

Question 29

What artery in the body contains high levels of co2?

Answer 29

pulmonary artery

Question 31

Differences between humoral immunity and cell-medicated immunity?

Question 32

#6 structure

Question 33

Function of osteogenesis. what is necessary for the proccess?

Question 34

t/f the pulmonary vein is highly saturated with co2

Question 36

What takes place at the loop of henle? how does it impact the collecting duct?

Question 37

t/f macophages are not a phagocytic cell?

Question 38

Hypertonic solution?

Answer 38
