26
Q

Where is the glenohumeral joint and what type of joint is it?

A

A ball-and-socket joint in the shoulder

27
Q

What are the two joints in the elbow and what do they connect? What do they do?

A

One is between the trochlea and the trochlear notch, which allows for flexion and extension.

The other is between the capitulum and the radial head, which allows for pronation and supination.

28
Q

Which 4 wrist bones attach to the arm bones (in order, starting with the thumb side)?

A

Scaphoid, Lunate, Triquetrum and Pisiform (but the pisiform is a pea-shaped bone that rests on top of the triquetrum)

29
Q

Which 4 bones attach to the fingers? (in order, starting with the thumb side)?

A

Trapezium, Trapezoid, Capitate, Hamate

30
Q

What are the fingers called?

A

metacarpals

31
Q

How many phalanges does each finger have?

A

The thumb has 2 phalanx and the fingers has 3.

32
Q

Does abduction or adduction translate to the direction of a “sickle” in dance?

A

adduction

33
Q

Why is the first metacarpal (thumb) so mobile and able to perform opposition?

A

Because the joint between it and the trapezium is saddle-shaped, which allows for movement.

34
Q

What is the os coxae?

A

The hip bone

35
Q

Which three os coxae bones fuse in the middle?

A

The illium, iscium and pubis.

36
Q

Where is the illiac crest?

A

On the superior side of the hip bone.

37
Q

What is the auricular surface?

A

A large joint for the sacral illiac

38
Q

Where is the greater sciatic notch?

A

On the posterior side of the hip bone

39
Q

What is another name for the sitz bone?

A

Ischial tuberosity

40
Q

What is the acetabulum?

A

The circular area where the hip joint forms

41
Q

What is the pubic symphysis?

A

The joint where the right and left pubic bones meet.

42
Q

What is the difference between a male and female pelvis?

A

The female’s cavity is much larger to allow for childbirth.

43
Q

Where are the greater and lesser trochanters located in the femur?

44
Q

What attaches to the intertrochanteric line?

A

A ligament

45
Q

Which muscles attach to the linea aspera?

A

The adduction muscles

46
Q

What do the medial and lateral condyles in the femur attach to?

A

The knee joint

47
Q

What does the patellar surface attach to?

A

The knee cap joint

48
Q

The hip is very stable. Why is this strange and what makes this so?

A

Strange because it’s a ball-and-socket joint, but it is very stable due to strong, thick ligaments.

49
Q

What is the iliofemoral ligament?

A

The ligament that provides stability in extension (ie. back bends)

50
Q

The tibia is ____ and the fibula is ____ (medial/lateral)

A

Tibia = medial, fibula is lateral

51
Q

What attaches to the tibial tuberosity?

A

The quadriceps tendon

52
Q

What does the fibula’s head touch?

A

The tibia’s medial condyle

53
Q

What do the lateral and medial malleolus do?

A

They link the leg to the foot.
