25
Where would you find the vital capacity?
Top of the graph to the bottom of the ERV
26
Where would you find the residual volume?
Bottom of ERV to bottom on the graph
27
Where would you find the functional RV?
Bottom of tidal volume to the bottom of the graph
28
How do you manually calculate the TLC (liters)?
Add TV, IRV, and ERV to 1.2L
29
How do you measure the TV?
Top and bottom of the little peaks
30
How would you measure the IRV?
Top of the last TV (before the big peak) to the bottom of the big peak (other side of it- big dip)
31
How would you measure the ERV?
Bottom of the last TV (before the big peak) to the bottom of the big peak (other side of it- big dip)
32
How do you measure the VC?
Top of the big peak to the bottom of the big peak (in the big dip)
33
How do you calculate the number for the RV?
Trick question: its 1200mL or 1.2L
34
In the special senses lab, what is a cutaneous response?
Warmth, cold, touch, and pain
35
What did we use to test the cutaneous response?
A paper clip
36
What is a two point threshold?
How far apart someone can feel 2 points on their body (we used hands)
37
What did we do for the referred pain test?
Tapped the elbow with a mallet to see if you felt tingling or pain in your fingers
38
What was the accommodation test?
We moved a pen towards someone’s eye and measured how far away it got blurry
39
How did we do the blind spot test?
A blue paper with a penny - look at the opposite penny and see when the other disappears
40
What is rinne’s test?
Hearing: bone conduction (behind ear)
41
What is Weber’s test?
Hearing: bone conduction (on head)
42
What is the binaural test?
If you can tell where a sound is coming from
43
How do you calculate hematocrit percentage?
RBC/total x 100% Total being: plasma + RBC
44
Which blood tests did we do?
Hematocrit Blood glucose test Blood coagulation time
45
How did we do the blood coagulation time test?
We put a large drop of blood on a slide and every 30 seconds stirred it with a toothpick to see if it had clotted
46
What is muscle tetanus?
When the muscle no longer relaxes in between contractions
47
What did we do the 2 point test on?
Back of hand Palm Finger tip Upper forearm
48
How did we obtain muscle tetanus?
Increase frequency
49
What muscle did we use on the frog to test tetanus? (the technical name, not the common one)
Gastrocnemius
50
Does acetylcholine increase or decrease heart rate?
Decrease
51
Is acetylcholine parasympathetic or sympathetic?
Parasympathetic
52
What does epinephrine do to the heart?
Increase heart rate
53
In an EKG, what shows ventricular contraction?
QRS
54
In EKG, what shows atrial contractions?
P
55
In EKG, what shoes ventricular repolarizations?
T
56
On a muscle graph, where do you find L?
The gap before the hill
57
On a muscle graph, where do you find C?
First half of the hill
58
On a muscle graph, where do you find R?
Second half of hill
59
On a muscle graph, where do you find A?
Bottom of behind the hill to the top of the hill (it’s the height)
60
If your VC is 5000mL, IRV is 3000, and ERV is 1200, what is the TV?
800 TV+IRV+ERV=VC
61
What does a higher specific gravity mean?
More salt in the urine
62
How do you calculate urine production rate?
mL of how much you peed/Minutes of how long ago you drank
