Leg - Coggle Diagram
Leg
Neurovasculature
Outline the neurovascular supply of the leg and what each nerve and artery supplies.
Associated injuries
Lesion of what nerve results in foot drop? What function is lost in foot drop? What compartment performs this function? What sensory loss would be associated with footdrop?
Blood supply
What artery supplies the lateral compartment of the leg?
nerves
Describe the cutaneous innervation of the leg. What nerves contribute and to what regions?
Venous drainage
Why are venous valves clinically important in the lower limb? What is the skeletal muscle pump and how does it support lower limb vein function?
What are varicose veins? What causes varicose veins in the lower limb? How does blood flow differ in varicose veins as compared to normal veins of the lower limb?
What are varicose veins? What causes varicose veins in the lower limb? How does blood flow differ in varicose veins as compared to normal veins of the lower limb?
facia
How does the crural fascia compartmentalize the leg?
Describe the role of deep fascia in the lower limb with compartment syndrome. What structures are vulnerable to compression in compartment syndrome of the lower limb? What clinical intervention relieves this pressure in the affected compartment?
Where is the flexor retinaculum and what is its function?
List the structures that pass deep to the flexor retinaculum and posterior to the medial malleolus.
Where is the extensor retinaculum and what is its function?
Tendons & Joints
Joint actions
Outline the actions at the ankle joint, as well as at the intertarsal joints of subtalar and transverse tarsal joints, along with the muscles that accomplish them. Between what bones is the subtalar joint? The transverse tarsal joint?
Outline the actions at the metatarsophalangeal joints and interphalangeal joints.
Outline the actions at the knee joint, along with the muscles that accomplish them.
What actions do the anterior compartment of the leg perform? What are the attachments of these muscles? Which cross 1 vs 2 joints?
Tendons
What is the calcaneal tendon?
Muscle actions
What actions does the posterior compartment of the leg perform? What are the attachments of these muscles? Which cross 1 vs 2 joints?
What action/s does the lateral compartment of the leg perform? What are the attachments of these muscles?
