Q

Pectineus

A

medial muscle, short, flat muscle located just lateral to the adductor longus and partially covered by the rectus femoris and sartorius. Its proximal attachment is more anterior nd superior that the adductor longus or magnus, allowing it to act as a prime mover for both hip flexion and hip adduction through a large range

Q

Gluteus Maximus

A

largest, most superficial of the gluteal muscles

35
Q

Gluteus Medius

A

largest of the lateral muscles and is most fundamental hip abductor

36
Q

Gluteus Minimus

A

deepest of the three

assist with greater resistance or in specific positions of the joint

37
Q

Iliotibial band (IT band)

A

a strong fascia of the lateral thigh that spans between the pelvis and lower leg

38
Q

Tensor Fascia Latae

A

O- anterior outer crest of ilium; lateral aspect of ASIS
I-lateral tibia via iliotiial tract (a long tendon)
A- Abducts, flexes and medially rotates femur. plays an important role in keeping pelvis in a neutral position, and not laterally rotated or tilted.
***stabilizes the knee joint because it inserts on tibia. stabilizes the trunk on the leg by making the ilitibial tract taut.

39
Q

Hamstring group

A

biceps femoris* why is it asterisked?
semitendinosus
semimembranosus
work horse, most important group

40
Q

Biceps femoris

A

O-long head-ischial tuberosity
Origin of short head- middle of femur
I- head of fibula
A- flexes knee and extends thigh-ALSO laterally rotates lower leg when knee is flexed=control of turn out
-this muscle can be very tight at the insertion on the fibula. stretch by lying on back and using thera-band on flexed foot lifted to 90 degrees- try varying degrees of turn out during this stretch
knee flexion and knee external rotation

41
Q

Semimembranosus

A

Hamstrings
O- ischial tuberosity
I- medial condyle of tibia
A- hip extension, hip internal rotation, knee flexion, knee internal rotation

42
Q

Semitendinosus

A 
Hamstrings
O-ischial tuberosity
I-medial condyle of tibia
A-flex knee and extend thigh
knee flexion and internal rotation
43
Q

Femoral Retroversion

A

good turnout, femur is facing straight our or slightly out

44
Q

Femoral Anteversion

A

this is bad turn out, when toes are slightly turned inward

45
Q

Fofsa

A

flat area of inner hip bone. iliopsoas is by the fofsa

46
Q

OOIA of 6 deep lateral rotators

A

O- anterior sacrum (inside of sacrum) (Piriformis only)
O-on the ischium (all but piriformis)
I- greater trochanter (all)
A- laterally rotates extended thingh (all)

48
Q

differences between male and female pelvis

A

Femail- broader and wider

male- narrower and deeper

49
Q

true pelvis

A

lesser

50
Q

false pelvis

A

greater

51
Q

inguinal ligament

A

joins pubic bone to ilium, is a ligament because when your brn your pelvis is not fully fused

52
Q

Ballet is differentiated from all other forms of dance by the use of?

A

turn out

53
Q

turn out provide

A

stability, range of motion, elongation of muscles

54
Q

*genetic constraints on turn out

MEMORIZE

A
  1. angle of femoral neck and angle at which head of femur is inserted into the socket
  2. orientation and depth of the socket itself
  3. elasticity of the iliofemoral (Y-shaped) ligament
  4. Flexibillity of muscles around the hip and thigh
55
Q

How much rotation occurs in hips?

A

70% is in the hips, what they cant get in the hip they get in the knee down

56
Q

How much takes place in lower leg and ankle

A

20%

57
Q

how can dancers increase range of motion without injury

A

stretching the antagonist that would keep you from turn outand strengthening the agonist

58
Q

What muscles activate turn out?

A

roles of:
Gluteals- actively engaged also engage deep rotators
Deep Outward rotators-
Sartorious-synergistic muscle that helps the quad maintain rotation
iliopsoas-if its short will pull tings inward, if long will allow the other muscles do the turning out
hamstrings-work in circular fashion, hamstring wrap around leg mentally and actively help turn out stay put

59
Q

Square hips in tendu, arabesques, high leg extensions?

A

No, not possible

60
Q

proximal is same as

A

origin

61
Q

distal attachment is same as

A

insertion

62
Q

extension in arabesque? involvement in lordosis?

A

if it is long and stretched out, then it will help with extension in arabesque, short it will not go as high and will pull the back into lordosis, shortening the back

63
Q

placement of pelvis

A

abdominals and gluteals

Both needed for correct placement of pelvis

64
Q

abdominals

A

holds pelvis vertically

65
Q

gluteals

A

feeds into IT band

66
Q

adductors

A 
adductor longus
adductor brevis
adductor magnus-deepest
gracilis
pectineus
67
Q

adductors

A

gluteus medius

gluteus minimus

68
Q

lateral muscles of the hip

A

gluteus medius

gluteus minimus

69
Q

tensor fasciae latae

A

TFL Muscle

why is it important?

70
Q

medial muscles of the hip

A 
inner thigh muscles
adductors
-adductor longus
-adductor brevis
-adductor magnus
