Extensor Tendonitis Tendinopathy The extensor tendons of the toes are actually the fibrous extensions of the muscles that are located on the front side of the lower leg and help to extend the toes. There are two main extensor tendons: the extensor hallucis longus tendon (extends the big toe) and the extensor digitorum longus tendon (extends the four small toes). Both the tendons pass in front of the ankle and travel along the upper surface of the foot, finally inserting into the toe bones.

Normal Adult Colonic Anatomy in Colonoscopy The cecum is usually located in the right iliac fossa. In the pole of the cecum, there is often the appearance of fusion of the three teniae coli around the appendix, giving rise to the tri-radiate fold (‘Mercedes Benz’ sign), but the anatomy can be variable. The most reliable landmarks of the cecum are the appendiceal orifice and ileocecal valve. The appendiceal orifice is usually an unimpressive slit, often crescentic in shape. The ileocecal valve is made up of the superior and inferior lips (usually not seen en face) and is the gateway leading into the terminal ileum.

Flexor & Extensor Muscles in the Forearm Two flexor muscles lie deep in the front of your forearm. The flexor digitorum profundus, or FDP, and flexor pollicus longus, or FPL. Tendons from the FDP travel along your fingers and attach just above the top crease in your index, middle, ring and small fingers. This muscle bends the tip of these fingers. The median nerve powers the tendons to your index and middle fingers, while the ulnar nerve powers the tendons to your ring and small fingers. The FPL muscle bends your thumb with a tendon that attaches just above your thumb crease. This muscle is powered by the median nerve.
