Test 4 Flashcards
This ligament connect sacrum and ilium posteriorly and blends with the sacrotuberous
Posterior SI ligament
Where does saphenous cutaneous nerve originate from
Femoral nerve, descends through adductor canal and supplies skin on medial side of leg and foot

Superficial peroneal and sural nerves
What does superficial peroneal cutaneous nerve supply
Skin on distal 1/3 of anterior surface of leg and dorsum of foot
What ligament is known as the spring ligament
Plantar calcaneonavicular ligament
What is the angle called for the plane of acetabular rim (common for X-rays)
Angle of Wisberg
Blood supply lateral compartment of leg
Peroneal Artery
What does anterior intermuscular septum separate
Anterior and lateral compartments of leg
What does arcuate artery give rise to
Digital arteries for digits 2-5
What does medial plantar nerve Innervate
Abductor hallucis flexor hallucis brevis Flexor digitorium brevis Medial lumbrical Sensory to medial sole of foot and medial 3.5 digits
Where does sural nerve originate
Tibial portion of sciatic nerve and common peroneal nerves to supply the skin of posterior and lateral aspects of leg and foot
What nerve innervates the anterior compartment of leg
Deep peroneal nerve
What is the plantar aponeurosis
Thickening of plantar fascia
What does plantar aponeurosis span
Medial process of calcaneus to heads of metatarsals
What is purpose of retinacula
To keep tendons in place
What does the transverse crural septum separate
Posterior septum into deep and superficial layer
What runs posterior to the medial malleolus
Tibial Posterior Flexor digitorium longus Posterior tibial artery Tibial nerve Flexor hallucis longus
What bursae are extensions of hip joint synovial capsule
Under ilipsoas and under tendon of Obturator externus
Where does the medial plantar artery pass through
Distally between abductor hallucis and flexor digitorium brevis between layers 1 and 2
What happens during plantar fasciitis
Arches fall
What innervates posterior compartment of leg
Tibial n
What cutaneous nerve supplies the medial side of the foot
Saphenous
What is fascia known as in leg
Crural fascia
Where does the lateral plantar artery pass through
Laterally between flexor digitorium brevis and quadratus plantae (layers 1 and 2) to the base of the 5th metatarsal where it turns to go between the 3rd and 4th layers to the base of the 1st metatarsal where it is then the plantar arch
What are the arches of the foot
Medial longitudinal
Lateral longitudinal
Transverse
What is pathway of anterior tibial artery
Branches off popliteal artery and passes between tibia and fibula to descend down anterior compartment where it turns into dorsalis pedis Artery as it reaches dorsum of foot
What is fascia known as in the thigh
Fascia lata
Where does tibial nerve travel
With posterior tibial artery down posterior leg, passing posterior to medial malleolus where it divides into medial and lateral plantar nerves in sole of foot
Where does deep peroneal nerve travel
With anterior tibial artery and ends by branches that Innervate the ankle joint and skin between first and second digits.
What does the plantar arch give rise to
Metatarsal and digital arteries to supply tarsal joints, digits 1-5 and surrounding musculature
What does dorsalis pedis artery give rise to
Deep plantar artery and arcuate artery
What does posterior intermuscular septum separate
Lateral and posterior compartments of leg
What nerve innervates lateral compartment of leg
Superficial peroneal
Ligaments of SI joint
Interosseus SI ligament Posterior SI ligament Anterior SI ligament Iliolumbar ligament Sacrotuberous Sacrospinous
Where does posterior tibial artery pass
Posterior to medial malleolus where it divides into medial and lateral plantar arteries
What tendons form stirrup mechanism
Tibialis Anterior
Tibialis Posterior
Peroneus longus
Blood supply posterior compartment leg
Posterior tibial artery
What does deep peroneal cutaneous nerve supply
Skin on first interdigit space (flip flop toes)
What is blood supply for anterior compartment of leg
Anterior tibial artery
What does peroneal artery branch off of
Posterior tibial artery
What does the plantar arch join with
Deep plantar branch of dorsalis pedis artery
