	Extensor Carpi Radialis Longus \| massagetoday.com
		The extensor carpi radialis longus and brevis muscle-tendon units work together to extend the wrist and abduct the hand.
		To get a sense of this motion, imagine a traffic cop putting his hand out to say, “Stop.” The extensor carpi radialis brevis originates on the lateral epicondyle of the humerus and inserts at the base of the third metacarpal bone.
		The extensor carpi radialis longus lies lateral to the brevis.

		The extensor carpi radialis longus is a short, flat muscle that originates from the supracondylar ridge of the humerus and extends down the arm.
		The extensor digiti minimi (extensor digiti quinti proprius) is a small, slender muscle that originates from the lateral epicondyle of the humerus, and lies between the extensor digitorum and the extensor carpi ulnaris.
		The extensor pollicis longus originates deep in the forearm from the shaft of the ulna (the forearm bone on the index finger side), crosses over the tendons of the extensor carpi radiales brevis and longus and descends along the back of the thumb and inserts in the last phalanx of the thumb.

		Extensor carpi radialis longus is one of the five main muscles that control movement at the wrist.
		As the name suggests, this muscle is an extensor at the wrist joint, and travels along the radial side of the arm, so will also abduct the hand at the wrist.
		Being an extensor contained in the forearm, it is innervated by the radial nerve.

	Muscle Associations : Ipsilateral association
		We have found that a pathology to an organ, joint, or bone will reveal itself by a dual imbalance of the proximal and distal agonistic and antagonistic muscles, tendons, or joint structures associated with it.
		Cystitis, for instance, will reveal a double imbalance of the flexors and extensors of the foot, the hand, the neck, and locally of the lower abdominals and the last lumbars.
		It is also an internal rotator and extensor when contracting the anterior muscle fibers and is an external rotator and extensor when contracting the posterior muscle segment.

		The term 'tennis elbow' was introduced in the 1880s but it was not until 1979 that pathology of the extensor carpi radialis brevis tendon was associated with lateral tennis elbow [62].
		At surgery in over 600 cases of lateral tennis elbow, Nirschl found the extensor carpi radialis brevis tendon to contain disrupted collagen fibres, increased cellularity and neovascularisation [63].
		Examples include paratenonitis of the abductor pollicis longus and extensor pollicis longus (De Quervain's disease), and of the flexor hallucis longus as it passes the medial malleolus of the tibia [5, 86].
