Answer 13

Ext. dig. Long. Is on anterior side of lower leg, lateral from tibialis anterior. Inserts into distal phalanges of digits 2-5 and extension of digits 2-5

Flexor digitorum longus - most medial side of deep calf (Part of TOM, DICK, and HARRY), insertion to inferior surfaces of the distal phalanges of digits 2-5

Question 14

T or F

Splenius capitis involves ipsilateral rotation of the head

Answer 14

T

Question 15

T or F

Semispinalis cervicis action involved so trilateral rotation of the head

What is contralateral rotation

Answer 15

T

Turning the head away from the side of the body that contains the muscles performing the action

Question 16

Name some muscles that contralaterally rotate the head

Answer 16

SCM, multifidus, semispinalis cervicis,

Question 17

Name some muscles involved in ipsilateral rotation of the head

Answer 17

Splenius cervicis, splenius Splenius capitis, obliquus capitis inferior, rectus capitis posterior major, obliquus capitis superior

Question 18

The femoral artery divides into what artery and then they artery divides into what two arteries?

Answer 18

Popliteal artery

Then divides into the posterior tibial artery and anterior tibial artery

Question 19

Name the O: and I: of the biceps femoris long head and then short head

Answer 19

Long head
O: Lateral surface of the head of the fibula

I: Lateral surface of the dead of the fibula

Short head
O: Linea aspera of the femur

Answer 20

O: anterior side of sacrum between S1 and 4

I: greater trochanter

A: Lateral rotation, abduction of the thigh at the high

Question 21

Differentiate Tibialis posterior from fibularis tertius.

Answer 21

TP- inserts on navicular bone

FT- inserts on dorsal surface of the bast os metatarsal 5 (Anterior side of calf region)

Question 22

What are Tom, dick, and harry? Where do they insert?

Answer 22

*All go behind medial malleolus
Tom - tibialis posterior, inserts tuberosity on navicular bone and slips to cuneiforms metatarsals 2-4

Dick - Flexor digitorum longus (MUSCLE IS MOST MEDIAL, but crosses tibialis, posterior tendon), Inserts inferior surfaces of the distal phalanges of digits 2-5

Harry - flexor hallucis longus (most lateral of the three) inserts inferior surface of the distal phalanx of digit 1 (great toe)

Answer 24

O: AIIS
I: common tendon fo the quadriceps
A: extension of the leg at the knee joint, flexion of the hip

Answer 25

Sartorius, adductor longus, inguinal ligment

Femoral artery and nerve run through this triangle
