Week 5: Posture and Anterior Thigh

What are the minimum muscles used for standing at ease?

Erector spinae, iliopsoas, triceps surae

What defines the gait cycle?

ONE cycle of swing and stance by ONE limb

Lateral edge of adductor longus

Lateral border of the femoral triangle

Sartorius (medial edge)

Floor of the femoral triangle

Iliopsoas and pectineus

Roof of the femoral triangle

Fascia lata and cribriform fascia

Name the contents of the femoral triangle, lateral to medial

Femoral nerve, femoral sheath (femoral artery, femoral vein, femoral canal with deep inguinal nodes)

What are the components of the femoral sheath?

Femoral artery, femoral vein, femoral canal with deep inguinal lymph nodes

What structures form the femoral sheath?
