18
Q

Tendons of the quadriceps form the quadriceps tendon which continues as

A

The patellar ligament

19
Q

The patellar ligament is attached to the

A

Tibial tuberosity

20
Q

Large sesamoid bone (triangular shape)

A

Patella

21
Q

Formed intrtendinously within quadriceps tendon, articulates with femur but not tibia

A

Patella

22
Q

When the patellar ligament is tapped briskly contraction of quadriceps is elicited resulting in extension of knee joint

A

Quadriceps reflex

23
Q

Exaggeration, slowing, or absense of the quadriceps reflex suggests that there may be

A

Damage to the central nervous system

24
Q

The patella causes the force generated by the quadriceps femoris to be

A

More parallel to the line of action on the tibia

25
Q

The patella is cartilagenous at birth and becomes ossified

A

Between 3rd to 6th year of age

26
Q

Stretching, straining, and tearing away of tendinous origin of adductors

A

Pulled groin

27
Q

Adductor longus origin and insertion

A

O: pubis, inferior to pubic crest
I: middle third of linea aspera

28
Q

Adductor longus and brevis nerve and action

A

N: obturator nerve
A: adducts thigh

29
Q

Adductor brevis origin and insertion

A

O: body and inferior ramps of pubis
I: pectineal line and proximal linea aspera

30
Q

Obturator externus origin and insertion

A

O: outer surface of obturator membrane, bony boundaries of obturator foramen
I: trochanteric fossa of femur

31
Q

Obturator externus nerve and action

A

N: obturator nerve
A: lateral rotation of thigh

32
Q

Adductor magnus origin and insertion

A

O: inferior ramus of pubis, ramus of ischium, ischial tuberosity
I: gluteal tuberosity, linea aspera, adductor tubercle

33
Q

Adductor magnus nerve and action

A

N: obturator nerve (adductor part) tibial part of sciatic nerve (hamstring part)
A: adducts thigh (adductor part) extends thigh (hamstring part)

34
Q

Opening at inferior insertion of adductor magnus, forms the inferior end of adductor canal through which passes the femoral vessels

A

Adductor Hiatus

35
Q

Gracilis origin and insertion

A

O: body and inferior ramus of pubis
I: superior part of medial surface of tibia

36
Q

Gracilis nerve and action

A

N: obturator nerve
A: adducts thigh, flexes and medially rotates leg

37
Q

The gracilis is a weak adductor and the only one in the group to

A

Cross the knee joint
