Q

The navicular bone is sandwitched between which bones?

A

Talus and 3 cuniform bones

26
Q

The navicular bone has a tuberosity on its lateral side.

What attaches to this?

A

Tibialis posterior

27
Q

The tuberosity at the base of the 5th metatarsal has which muscle attach to it?

A

Fibularis (peroneus) brevis

This can be felt halfway along the lateral border of the foot

28
Q

What muscle runs in the groove on the underside of the cuboid?

A

Tendon of the fibularis longus

29
Q

Which muscles flex the hip joint from lateral to medial?

A

Sartorius
Iliopsoas
Pecineus

30
Q

What are the attachments of the sartorius?

A

ASIS to medial surface of tibia

31
Q

The iliopsoas attaches to what part of the femur?

A

Lesser trochanter

32
Q

What are the actions of the pectineus?

A

Flexion and adduction of the hip

33
Q

Psoas major arises from where?

A

Lumbar vertebrae

34
Q

What is the action of the rectus femoris?

A

flexes the hip and extends the knee

35
Q

The fibrous structure in which the patella is embeded in arises from the quadraceps femoris.

Above the patella what is this called?

Below the patella to the tibial tuberosity what is this called?

A

Patella tendon

Patellar ligament

36
Q

What are the attachments of the gracillis?

A

Pubis to tibia

(inserts between the sartorius above and semitendinosis below) -> girl between two sailors

37
Q

Adductor longus arises from where?

38
Q

What are the attachments of the adductor brevis?

A

Pubis to linea aspira

brevis so shorter course

39
Q

What muscle usually covers the adductor brevis?

40
Q

What are the two parts of the adductor magnus?

A

Hamstring part -> attaches to adductor tubercle

True adductor part -> attaches to linea aspira

41
Q

What nerve innervated the gluteus maximus?

A

Inferior gluteal nerve

42
Q

What 3 muscles abduct the hip joint?

What nerve supplies them?

A

Gluteus medius
Gluteus Medius
Tensor fascia lata

Superior gluteal nerve

43
Q

What are the attachments of the piriformis?

A

Sacrum to the greater trochanter

44
Q

The superior and inferior gluteal nerves are named in relation to what?

A

Superior gluteal nerve superior to piriformis

Inferior gluteal nerve inferior to piriformis

45
Q

The obturator internus passes through which pelvic foramen?

A

Lesser sciatic foramen

46
Q

Name the lateral rotators of the hip from superior to inferior

A 
Piriformis
Superior gemellus
Obturator internus
Inferior gemellus
Quadratus femoris
47
Q

The sciatic nerve lies on the quadratus femoris midway between which two bony markers?

A

Ischial tuberosity

greater trochanter

48
Q

The hamstrings arise from where?

A

Ischial tuberosity

short head of biceps actually comes from the femur

49
Q

What are the names of the hamstrings?

A

Semitendinosus
Long head of biceps femoris
Short head of biceps femoris
Semimembranosus (proximal part is membranous)

50
Q

What nerve supplies the hamstrings?

A

Tibial portion of the sciatic nerve

51
Q

Which muscle isnt really a hamstring?

A

Short head of biceps femoris

Doesnt actually cross the hip joint so has no action here like the others do

Also different nerve supply -> common fibular branch of the sciatic nerve

52
Q

Name the muscles of the anterior compartment of the LEG from medial to lateral.

(medial to lateral in relation to the order they lie in at the ankle)

A

Tibialis anterior

Extensor digitorum longus

53
Q

Where does the tibialis anterior insert?

A

Medial cuniform and base of the 1st metatarsal

54
Q

What are the actions of the tibialis anterior?

A

Dorsiflexes
Inverts the foot

(supports the medial longitudinal arch of the foot)

55
Q

What are the actions of extensor digitorum longus?

A

Dorsiflexion

Extends the lateral 4 toes

56
Q

What muscle lies just between the tibialis anterior and the extensor digitorum longus and is quite hard to see?

A

Tibialis anterior
extensor Hallucis longus
(dorsalis pedis Artery)
Extensor digitorum longus

(talkative husbands are (not) efficient)

57
Q

Which muscle of the leg arises from the most inferior part of the EDL. It is not present in all individuals, and is considered by some texts as a part of the extensor digitorum longus?

A

Fibularis tertius (peroneus tertius)

58
Q

What nerve supplies all the muscles of the anterior leg?

A

deep fibular nerve

59
Q

What easily visible vein arises on the dorsum of the foot and passes anterior to the medial malleolus up the leg?

A

great saphenous vein

60
Q

Most if the muscles of the posterior compartment of the leg are supplied by which nerve?

A

Tibial nerve

61
Q

The popliteus performs which action

A

Unlocks the knee

Lateral rotation of the fumur with the foot planted on the ground

62
