Lecom - Popliteal Fossa, Leg And Foot

Front 1

What major structures run through the popliteal fossa?

Back 1

Popliteal artery and vein
Tibial and common fibular (peroneal) nerve

also included are:
small saphenous vein
Posterior cutaneous nerve of thigh
popliteal lymph nodes and lymphatics

Front 2

From where does the sural nerve arise

Where does it innervate?

Back 2

Medial and lateral sural cutaneous nerves that branch off of the tibial and common fibular respectively and join to form the sural nerve

skin on lateral side of leg and ankle

Front 3

Order the following structures from superficial to deep in the popliteal fossa:

popliteal artery
popliteal nerve
popliteal vein

Back 3

S--> D
Nerve
Vein
Artery

Front 4

Which muscles are in the lateral compartment of the leg?
Attachment
Innervation

Back 4

Fibularis longus
Fibularis brevis

both arise from fibula and send tendons around posterior side of lateral maleolus. Longus passes under foot to medial cuneiform and 1st metatarsal. Brevis attaches on lateral side to 5th metatarsal

Superficial fibular n. (peroneal)

Front 5

Where is the common fibular nerve particularly vulnerable to injury?

Back 5

Where it passes deep to the fibular muscles.

Much more exposed than artery

Front 6

the common fibular nerve divides into the deep fibular nerve which supplies the _______ compartment and the superficial fibular nerve which supplies the _______ compartment.

Back 6

anterior

lateral

Front 7

the lateral compartment of the leg receives its blood supply from

Back 7

perforating branches of anterior tibial artery
branches of fibular (peroneal) a.

Front 8

Give the anterior leg muscles and their innervation and blood supply

Back 8

Tibialis anterior
Extensor Hallucis longus
Extensor digitorum longus
Fibularis (peroneas) tertius

deep fibular nerve
anterior tibial artery

Front 9

What is the distal termination of the anterior tibial artery called?
Posterior tibial?

the anastamosis of these two distal terminations forms what?

Back 9

dorsalis pedis a.
lateral plantar a.

plantar arch of the foot

Front 10

Describe the route of the common fibular nerve starting from its roots in the spinal cord.

Back 10

refer to leg and popliteal fossa lecture slide 25

Front 11

Give the muscles of the posterior compartment of the leg and their innervation

Back 11

Superficial
Gastrocnemius
Soleus
Plantaris
Deep
Popliteus
Flexor halucis Longus
Flexor digitorum Longus
Tibialis posterior

All tibial nerve

Front 12

Posterior to the medial malleolus, some structures enter the foot under the flexor retinaculum

Give these structures from anterior to posterior

Back 12

Tom Dick And very Nervous Harry

Tibialis posterior
Flexor Digitorum Longus
Posterior tibial artery
Posterior tibial vein
Tibial nerve
Flexor hallucis longus

Front 13

Draw the tibial nerve from its origin as the sciatic nerve as well as a line to all the structures it innervates

Back 13

refer to leg and popliteal fossa lecture slide 36

Front 14

In the leg, what separates:

Anterior from deep posterior comp?
Anterior from lateral comp
Deep posterior from superficial posterior?
Superficial posterior from lateral

Back 14

Interosseous membrane
Anterior intermuscular septum
Transverse intermuscular septum
Posterior intermuscular septum

Front 15

Great saphenous vein is anterior/posterior to medial malleolus?

Back 15

anterior

Front 16

What are the three arches of the foot?

Back 16

medial longitudinal
lateral longitudinal
transverse

Front 17

The arches of the foot are supported by which ligaments?

Which tendons assist?

Back 17

plantar calcaneonavicular
Short and long plantar
plantar aponeurosis

tendons of
fibularis longus
tibialis anterior and posterior

Front 18

This is a thickening of deep fascia in the sole of the foot that supports the longitudinal arch.

Longitudinal bands of that thickening are connected distally by these ligaments

Back 18

plantar aponeurosis

Superficial transverse metatarsal ligaments

Front 19

What muscles are in the superficial layer of the plantar foot

Back 19

Adductor hallucis
Abductor digiti minimi
Flexor digitorum brevis

Front 20

The posterior tibial artery branches into what two arteries that supply the plantar foot?
Which one becomes the plantar arch?

Back 20

lateral and medial plantar arteries

lateral

Front 21

This artery is a continuation of the anterior tibial artery on the dorsal surface of the foot.

Back 21

Dorsalis pedis

Front 22

Describe the cutaneous innervation of the dorsum of the foot.

Back 22

The superficial fibular nerve provides most of the dorsal surface.

The proximal dorsomedial side get the saphenous nerve

the distal lateral side gets the sural nerve

The space between the great toe and the 2nd toe gets the deep fibular nerve

Front 23

Describe the cutaneous innervation on the plantar surface of the foot

Back 23

The heel is mostly tibial nerve (cutaneous calcaneal branch) also some of lateral calcaneal branch of sural nerve.

Lateral plantar nerve gets mid to distal 1/3
Medial plantar nerve gets mid to distal 2/3
Split down 4th toe

Front 24

This nerve innervates most of the intrinsic muscles of the foot

Back 24

lateral plantar nerve

Front 25

This nerve innervates
Flexor digitorum brevis
Flexor hallucis longus
Abductor hallucis

Back 25

medial plantar nerve
