- Extensor carpi radialis brevisExtensor radialis brevis carpiThe short radial wrist extensor runs from the lateral epicondyle on the humerus to the third metacarpal, lifting the wrist.
- Extensor carpi radialis longusExtensor radialis longus carpiExtensor carpi radialis longus runs from the lower humerus down the thumb side of the forearm to the second metacarpal, extending and abducting the wrist.
- Extensor digiti minimiExtensor digiti minimi is a slender muscle on the back of the forearm that straightens the little finger independently of the others.
- Extensor digitorumExtensor digitorum is the main finger extensor on the back of the forearm, sending a tendon to each of the four fingers.
- Extensor digitorum brevisExtensor brevis digitorumExtensor digitorum brevis is the small, fleshy muscle on top of the foot that straightens toes two to four.
- Extensor digitorum longusExtensor longus digitorumExtensor digitorum longus is the feather-shaped muscle on the outer front of the leg whose tendons straighten the four lesser toes.
- Extensor hallucis brevisExtensor brevis hallucisExtensor hallucis brevis is the small medial slip of the short toe extensor, lying on top of the foot and lifting the big toe.
- Extensor hallucis longusExtensor longus hallucisExtensor hallucis longus is the thin muscle in the front of the leg whose tendon lifts the big toe and helps raise the foot.
- Extensor indicisExtensor indicis is a narrow deep muscle of the back of the forearm that lets the index finger straighten on its own.
- Extensor pollicis brevisExtensor brevis pollicisExtensor pollicis brevis is a short deep forearm muscle that extends the thumb at its knuckle and borders the anatomical snuffbox.
- Extensor pollicis longusExtensor longus pollicisExtensor pollicis longus is a deep forearm muscle whose tendon hooks round a radial tubercle to straighten the tip of the thumb.
- External abdominal oblique muscleMusculus obliquus externus abdominisThe external oblique is the outermost and largest flat muscle of the side and front of the abdominal wall.
- External anal sphincterSphincter externus aniThe external anal sphincter is the ring of voluntary skeletal muscle around the lower anal canal that keeps the anus closed.
- External carotid arteryCarotis externaOne of the two terminal branches of the common carotid artery, supplying the neck, face, scalp and much of the skull.
- External iliac arteryArteria iliaca externaThe larger terminal branch of the common iliac artery, following the pelvic brim to pass under the inguinal ligament as the femoral artery.
- External iliac veinVena iliaca externaA paired pelvic vein continuing the femoral vein from the inguinal ligament along the pelvic brim to the front of the sacroiliac joint.
- External intercostal membraneMembrana intercostalis externaA thin aponeurotic sheet in the front of each intercostal space, continuing the external intercostal muscle forwards to the sternum.
- External intercostal musclesMusculi intercostales externiThe external intercostals are the outermost layer of muscle filling each space between neighbouring ribs, used mainly in breathing in.
- External jugular veinVena iugularis externaA large superficial vein that crosses the side of the neck from the angle of the jaw to the subclavian vein.
- External part of thyro-arytenoid musclePars externa musculi thyreoarytenoideiThe external part of thyro-arytenoid is the main outer sheet of that laryngeal muscle, lying beside the vocal fold.
- Facial arteryArteria facialisA winding external carotid branch that hooks over the mandible and runs across the face to the inner corner of the eye.
