Flashcards in Lab 17-19: Posterior Compartment of Leg Deck (23):
1

most frequent termination of small saphenous v

popliteal v in the back of knee
- however, may continue into thigh and terminate in accessory saphenous v or deep veins of posterior compartment of thigh

2

what n. is formed by the union between medial sural cutaneous n and the peroneal communicating branch of lateral sural cutaneous n.

sural n.

3

origin of peroneal communicating branch of lateral sural cutaneous n.

branch of common peroneal n.

4

origin of medial sural cutaneous n.

branch of tibial n.

5

what n. is found b/w the two heads of the gastrocnemius

medial sural cutaneous n.

6

fabella

- a sesamoid bone in the lateral head of the gastrocnemius m.
- found in 3-5% of cases

7

n. supply to gastrocnemius

sural branch of tibial n.

8

blood supply to gastrocnemius

sural branch of popliteal a

9

tendon of gastrocnemius

tendo calcaneus

10

tendon located b/w soleus and gastrocnemius

tendon of plantaris

11

insertion of tendon of plantaris

calcaneus

12

triceps surae

soleus and gastrocnemius

13

the tendon of origin of the popliteus lies _________ to the arcuate popliteal ligament of knee joint

inferior

14

what does the bundle between the flexor hallucis longus and flexor digitorum longus contain?

neurovascular bundle containing the posterior tibial vessels and the tibial n.

15

the popliteal a. terminates by ...

giving off the anterior and posterior tibial arteries

16

the posterior tibial recurrent a is a branch off of ...

anterior tibial a.

17

from where does the circumflex fibular a. usually originate?

posterior tibial a.

18

course of the circumflex fibular a.

courses laterally through the soleus and around the neck of the fibula to join the circumpatellar anastomosis

19

second branch off the posterior tibial a.

tibial nutrient a. (goes directly into bone) OR peroneal a.

20

largest branch of posterior tibial a.

peroneal a.

21

where would you locate the communicating branch of the posterior tibial a. ?

3 or 4 cm superior to the distal end of the tibia
- this branch courses deep to the tendon of flexor hallucis longus and connect posterior tibial with the peroneal a.

22

what is the origin of the posterior medial malleolar a? posterior lateral malleolar a?

- posterior tibial
- peroneal a.

23

separating the bellies of the flexor hallucis longus and flexor digitorum longus, what m. do you expose?

tibialis posterior m.
