Anatomy Dissection 6 Flashcards
What foot joint is between the talus and calcaneus?
Subtalar joint
What two joints make up the midtarsal joints?
- Calcaneocuboid
2. Talocalcaneonavicular
In relation to the midtarsal joint: what two muscles produce inversion with tibial and deep fibular nerve?
Tibialis anterior and posterior
In relation to the midtarsal joint: what muscles produce eversion with fibular nerves?
Fibularis muscles
What foot joint is between the cuneiforms/cuboid proximally and the metatarsals?
Tarsometatarsal
What synovial joint of the foot allows flexion, extension, abduction, adduction and circumduction of the digits?
MTP
What joint of the foot allows flexion and extension of the toes?
Interphalangeal
What structures of the foot provide shock absorption, push off spring in function and increased weight bearing capacity by weight distribution across the whole foot?
Arches of foot
What two structures support the arches of the foot?
Plantar aponeurosis
Plantar ligaments
What is the thickened central area of the plantar fascia, the deep fascia of the sole of the foot?
Plantar aponeurosis
What arch is composed of bones of the medial aspect of the foot (calcaneus, talus, navicular, 3 cuniforms and metatarsals 1-3)?
Medial longitudinal arch
What is the medial longitudinal arch supported by?
Flexor hallucis longus, attachments of tibialis anterior and fibularis longus
Where does tibialis anterior attach to?
Junction between medial cuniform and base of 1st metatarsal
Where does the fibularis longus tendon attach to?
Medial cuniform and base of 1st metatarsal
What arch is formed by calcaneous, cuboid, metatarsals 4&5 and is usually weight bearing on standing?
Lateral longitudinal arch
What arch consists of cuboid, cuniforms and bases of all 5 metatarsals - also supported by fibularis longus and TA?
Transverse arch
What intrinsic muscles of foot produce flexion of toes?
Sole muscles
What intrinsic muscles of foot produce abduction.adduction of the toes?
Interossei
What is the dorsalis pedis artery a branch of and what does it branch to give?
Branch of anterior tibial artery
Branches to give arcuate artery on dorsum of foot
What are the medial and lateral plantar arteries branches of and what do they both contribute to?
Posterior tibial artery
Deep plantar arch
Where do metatarsal arteries come from?
Deep plantar arch and arcuate artery
What does the dorsal venous arch give rise to?
Great (medially) and small (laterally) saphenous veins
What do deep veins of the foot drain into?
Anterior and posterior tibial and fibular veins
What nerve supplies motor to the sole muscles?
Tibial
What nerve supplies motor to the muscles of dorsum?
Deep fibular
In relation to the sensory nerve supply of foot on dorsum: what supplies the first interdigital cleft?
Deep fibular nerve
In relation to the sensory nerve supply of foot on dorsum: what supplies the proximal lateral border?
Sural nerve
In relation to the sensory nerve supply of foot on dorsum: what supplies the proximal medial border?
Saphenous nerve
In relation to the sensory nerve supply of foot on plantar surface: what supplies heel and majority of sole?
Tibial nerve
In relation to the sensory nerve supply of foot on plantar surface: what supplies proximal lateral border?
Sural nerve
In relation to the sensory nerve supply of foot on plantar surface: what supplies proximal medial border?
Saphenous nerve
