Nerve & Muscles
This nerve innervates the anterior compartment of the leg.
What is the Deep Fibular Nerve?
These two circumflex arteries provide the major arterial supply around the hip.
What are the Medial & Lateral Circumflex Femoral Arteries?
The lateral ligaments of the ankle primarily resist this movement.
What is Inversion?
Name the three major structures of the femoral triangle in lateral-to-medial order.
What is the Femoral Nerve, Femoral Artery, and Femoral Vein?
This cranial nerve provides motor innervation to the muscles of facial expression.
What is the Facial Nerve (CN VII)?
This nerve supplies both the superficial and deep posterior compartments of the leg.
Of the two circumflex femoral arteries, this one provides the major blood supply to the hip joint.
What is the Medial Circumflex Femoral Artery?
This knee ligament resists valgus forces.
What is the MCL?
These two nerves travel through the adductor canal along with the femoral artery and vein.
What is the Saphenous Nerve & Nerve to Vastus Medialis?
This division of the trigeminal nerve supplies the muscles of mastication.
What is the Mandibular Division (V3)?
Weakness of these two muscles produces a positive Trendelenburg sign.
What is the Gluteus Medius and Gluteus Minimus
This artery is the continuation of the popliteal artery and travels in the anterior compartment of the leg before becoming the dorsalis pedis artery at the ankle.
What is the Anterior Tibial Artery?
A blow to the medial side of the knee places this collateral ligament at greatest risk.
What is the LCL?
These four structures pass through the tarsal tunnel beneath the flexor retinaculum.
What are the Tibialis Posterior, FDL, Posterior Tibial Artery/Tibial Nerve, and the FHL?
Name the three major structures contained within the carotid sheath.
What is the Carotid Artery, Internal Jugular vein, and Vagus Nerve?
This nerve innervates the lateral compartment of the leg.
What is the Superficial Fibular Nerve?
The superior and inferior gluteal arteries arise from this major artery within the pelvis.
What is the Internal Iliac Artery?
A positive anterior drawer sign suggests injury to this structure.
What is the ACL?
This opening transmits the obturator nerve and obturator vessels into the medial thigh.
What is the Obturator Canal?
This cranial nerve crosses the posterior cervical triangle on its way to the trapezius.
What is the Spinal Accessory Nerve (CN XI)?
During single-leg stance, the pelvis drops on the unsupported side. Name the affected nerve and the gait pattern.
What is the Superior Gluteal Nerve; Trendelenburg Gait?
In subclavian steal syndrome, proximal subclavian occlusion causes blood to reverse direction through this artery during upper-extremity activity.
What is the Contralateral Vertebral Artery?
Name all three structures classically injured in the unhappy triad.
What is the ACL, MCL, and Medial Meniscus?
Name the nerve and vessels that exit the greater sciatic foramen, wrap around the ischial spine, and then enter the perineum through the lesser sciatic foramen.
What is the Pudendal Nerve & Internal Pudendal Vessels?
The facial nerve passes through the parotid gland, but parasympathetic secretomotor innervation to the gland originates from this cranial nerve.
What is the Glossopharyngeal Nerve (CN IX)?
