Heh.

So apparently I have more studying to do. I just gave myself an Anatomy exam for the unit based off of my notes, and I got a 39/52. Here's my quiz: Feel free to erase my answers and take it yourself!

QUIZ

1. Seven qualities by which muscles are named:

Size (magnus)
Direction (rectus)
Relative to Axis
Shape (trapezius)
Function (adductor)
Location (brachii)
Origin
Number of origins (biceps)

2. Myofibers are _multinucleated_; they're positioned peripherally. Cardiac fibers are _uninucleated_; it's in the center.

3. Myofibers are composed of _thick_ and _thin_ myofibrils, which comprise _myosin_ and _actin_ respectively.

4. SR = sarcoplasmic reticulum
a. stores calcium

****5. Structure of the Sarcomere.
M line:
Z line:
H Zone:
I band: isotropic
A band: anisotropic

6. Actin comprises:
F Actin stands for: filament
G actin stands for: globular

7. Covers active sites: tropomyosin

8. Holds #7 in place: troponin

****9. 7 kinds of muscle movement:
abduction
adduction
rotation
flexion
extension
circular movement of arms

10. Shaped like golf club: myosin
Head: heavy chain
Tail: light chain

11. Two movements of wrist: supination and pronation
****12. Two movements of ankle:
****13. Two movements of foot: plantar flexion
14. Three movements of head: right rotation, left rotation, flexion

15. Smooth muscle fiber is not _striated_ and therefore is not organized into _sarcomeres_.

****16. Corresponds to Z lines in cardiac muscle:

17. Regulates calcium: calmodulin
****18. Activated by #17: enzymes, fuck!
Does what (P)?
****19. Undoes effect of #18:
Does what?

20. Corresponds to Z lines in smooth muscle: Dense bodies

21. Three components of CV system: arteries, veins, lymphatic

22. Four parts of heart: right atrium, left atrium, left ventricle, right ventricle

23. Heart is cone shaped, and the _apex_ points down and left, _base_ points up and right.

24.

The _right atrium_ receives O2 poor blood, which is pumped into the _lungs_ via the _right ventricle_. _Oxygenation_ occurs in the lungs. O2 rich blood is then pumped through the _left atrium_ into the _left ventricle_, which pumps the blood out to the body.

25. Homeostasis: equilibrium of fluid

26. Membrane surrounding the heart and its two halves: visceral (inner) and parietal (outer) pericardium.

Between two halves: pericardial cavity

27. Musculature of heart = myocardium

28. The atrial walls are known as: auricles

29. Deep groove separating...
the auricles: coronary sulcus
atrium and ventricle: atrioventricular (AV) sulcus
the ventricles: interventricular (IV) sulcus

30. Valves on:

Right side: tricuspid
Left side: bicuspid

31. Three vessels emptying into RA: coronary sinus, superior vena cava, inferior vena cava

32. Fibrous CT ring in heart is called: annulus fibrosis

33. Valve between RA and RV: tricuspid

****34. Valves are controlled by _________ _chordae_ and those are controlled by _papillary_ muscles.

****35. Fleshy columns that allow for contractions in all directions:

****36. Unique funnel to RV:

37. Semilunar valves lack: chordae and papillary muscles

38. Valve between LA and LV (two names): bicuspid, mitral

39. Generic name for valves #33,#38: atrioventricular (AV) valves

40. Three parts of the conducting system:
SA node:
aka: pacemaker
AV node: backs up the SA node
AV bundle of _His_

****41. Muscle fibers that look like nerve fibers, that come down from AV node to IV septum:
...does what?

42. Three components of blood vessels: Tunica interna (intima), tunica media, tunica externa (aventura)

****43. Circulatory system has its own circ system. The vessels are called: vaso vas...

44. Three types of arteries: axial arteries, medium arteries, arterioles

45. Three types of veins: large veins, medium sized veins, venules

46. Tunicae in arteries have this which veins lack: elastic membranes

47. Blood vessel expansion and constriction: vasoconstriction and vasodilation

48. Analyze 120/80 blood pressure:

****49. Openings in the capillaries: F

50. Capillaries are guarded by the _precapillary_ sphincter.
This is big enough for red blood cells to go through in: single file

51. When #50 closes, blood flows through a preferred channel: metarteriole

52. Bypass for blood if its not needed in capillary bed: arteriovenular anastomosis

So yeah. I have more studying to do, cuz that's a C. I can do better than that, and I will because I'll be studying my little Irish balls off tomorrow! Glad there's a study group tomorrow! Hope to see you all there!

And I'll still be cool and send you my notes if you hit me up for them. Shoot me an email.
