Q

What is the interosseous talocalcaneal ligament’s function?

A

helps to stabilise the subtalar joint along with the cervical ligament. The primary function of the cervical ligament is to resist excessive joint supination whereas the ITC ligament remains taut during pronation.

Q

Name the retinaculum that makes up the roof of tarsal tunnel?

A

flexor retinaculum of the ankle joint

18
Q

What are two muscles that are innervated by the medial plantar nerve?

A

abductor hallucis, flexor hallucis brevis, EDB and first lumbrical

19
Q

What is another name for the plantar calcaneonavicular ligament?

A

spring ligament

20
Q

What is the spring ligament’s function?

A

static restraint of the medial longitudinal arch, it supports the head of the talus from plantar and medial subaxation against the body weight during standing

21
Q

What is the nerve that winds around the neck of fibula?

A

common fibular nerve

22
Q

what vessel continues from the medial end of the subcutaneous dorsal venous arch, just anterior to the medial malleolus?

A

greater saphenous vein (superficial vein)

23
Q

Name the muscle tendon that inserts on the tuberosity of the fifth metatarsal bone?

A

fibularis/ peroneus brevis

24
Q

Name the muscle tendon that inserts on the tuberosity of the navicular bone?

A

tibialis posterior tendon

25
Q

What bony surfaces of the foot make up the calcaneocuboid joint?

A

anterior surface of the head of calcaneus and the proximal surface of the cuboid

26
Q

what type of joint is the distal interphalangeal joint?

A

hinge type of synovial joint

27
Q

What muscle forms the floor of the popliteal fossa?

A

popliteus

28
Q

what is the function of popliteus?

A

when walking, when the foot is in contact with the ground, the muscle externally rotates the femur on the tibia/ unlocks the extended knee

29
Q

A

lateral leg, border of the ankle and foot

30
Q

Where does the great saphenous vein drain it’s poorly oxygenated blood?

A

femoral vein

31
Q

Name one of the major deep branches of the femoral artery?

A

deep artery of the thigh, (profunda femoris artery or deep femoral artery)

32
Q

What makes up the pes anserinus tendon?

A

consists of the conjoined flattened tendons of the sartorius, gracilis and semitendinosus tendon

33
Q

What is a continuation of the femoral artery, passing through the adductor hiatus?

A

popliteal artery

34
Q

Where does the pes anserinus tendon insert and what is it’s function?

A

into the proximal tibia and acts as a secondary valgus restricitng something the medial supporting structures of the knee ***

35
Q

What muscles make up the levator ani?

A

iliococcygeus, puborectalis, pubococcygeus

36
Q

What bony structure gives attachment to the sacrospinous ligament?

A

ischial spine and lateral sacrum

37
Q

What bony structure gives attachment to the sacrotuberous ligament?

A

iliac tuberosity and lateral sacrum and coccyx

38
Q

What bony structure gives attachment to the iliolumbar ligament and what function does it serve?

A

transverse process vertebra, joins the 4th and 5th lumbar vertebrae to the posterior iliac crest

39
Q

What is the function of the sacrotuberous, sacrospinous and iliolumbar vertebra together?

A

stabilisers of the sacroiliac joint and connection of the bony pelvis to the vertebral column

40
Q

what attaches to the lateral border of the anterior superior iliac spine?

A

muscle = sartorius muscle/ and part of tensor fasciae latae muscle
ligament = inguinal ligament
