more leg

Question 1

posterior superficial compartment of leg has which 3 muscles and what innervates it

Answer 1

gastronemius, soleus, and plantaris

tibialis n innervates it

Question 2

tricep surae

Answer 2

the three muscles of the posterior compartment that all insert into achilles tendon
gastronemius, soleus, plataris
“three headed calf”

Question 3

retrocalcaneal bursa

Answer 3

between calcaneous and achilles tendon

Question 4

what innervates both the deep and superficial posterior compartment of leg

Answer 4

tibial nerve

Question 5

muscles of the posterior deep compartment

Answer 5

poplitius (screw home mechanism that allows us to flex knee)
tibialis posterior
flexor digitorum longus
flexor hallicis longus

Question 6

tibialis posterior not only does plantar flexion, it also does…

Answer 6

inversion!

Question 7

if tibial nerve is injured what will be very difficult?

Answer 7

plantar flexion, ankle flexion, and inversion

Question 8

explain Tom Dick and Harry muscles

Answer 8

three deep posterior muscles go around the medial malleolus. Tibialis posterior (most medial) flexor Digitorum longus (in the middle) and flexor Hallicus longus (most lateral)
Tom Dick And Now Harry =
tibialis posterior, flexor digitorum longus, posterior tibial Artery, tibial Nerve, and flexor hallicis longus

Question 9

tarsal tunnel syndrome

Answer 9

the flexor retinaculum covers the muscles of the posterior deep compartment. It goes from the medial malleolus to the calcaneal tuberosity.
*if someone is really flat footed, it can leave to excessive compression on this area. It can lead to these tendons or artery being effected. They can show weakness, or numbness and tingling on plantar foot.

Question 10

ankle dorsi flexion is

Answer 10

lifting your toes to your nose, also called extension

Question 11

injury to deep peroneal fibular nerve can lead to this diagnosis

Answer 11

drop foot! they can not actively dorsi flex

Question 12

If fibular head fractures, what nerve can be effected?

Answer 12

common peroneal / fibular N

Question 13

what compartment are your leg dorsiflexors

Answer 13

anterior compartment

Question 14

what compartment are your leg plantar flexors

Answer 14

poster compartment

Question 15

what compartment are your leg everters?

Answer 15

lateral compartment

Question 16

what muscles are your inverters of the leg?

Answer 16

tibialis posterior & anterior and extensor hallicis longus

Question 17

sustenaculum tali

Answer 17

a bump on the medial side of calcaneus

it promotes elevation and maintenance of

Question 18

chassis effect

Answer 18

intertwining flexor digitorum longus and flexor hallicis longus

Question 19

which two muscles create a stir up for transverse arch?

Answer 19

tibialis posterior and peroneus longus

Question 20

pes planus

Answer 20

essentially a flat foot. its caused by failure of the transverse arch, which involves the tibialis posterior and peroneus longus
also tarsal tunnel syndrome makes you have a flat foot

Question 21

popliteal fossa is

Answer 21

the space behind the knee

Question 22

the borders of popliteal fossa:

Answer 22

it makes a diamond shape - first two are superior to 3/4

1. superolateral- bicep femoris
2. superomedial - semitendinosus and semimembinosus
3. med head -medial gastrocnemius
4. lat head - lateral gastrocnemius

Question 23

What is inside of the popliteal fossa?

Answer 23

popliteal fossa is back of knee so:
popliteal artery and veins
and your genicular arteries

Question 24

the femoral artery turns into the

Answer 24

popliteal artery

Question 25

the popliteal artery splits into the

Answer 25

anterior tibial artery at the popliteal fossa and posterior tibial artery

Question 26

once the anterior tibial artery gets to the tibia and fibula it splits and…

Answer 26

the anterior tibial artery stays anterior, and then there’s a posterior tibial artery that breaks off

Question 27

the anterior tibial artery eventually becomes

Answer 27

the dorsalis pedis artery once it hits the ankle joint
