'''''Common Digital Extensor Tendon'''''  

*'''Origin''': Common digital extensor muscle on the lateral humeral epicondyle

*'''Origin''': Common digital extensor muscle on the lateral [[Bones and Cartilages - Horse Anatomy#Humerus|humeral]] epicondyle

*'''Insertion''': Extensor process of [[Phalanges - Horse Anatomy#Distal Phalanx|distal phalanx]]

*'''Insertion''': Extensor process of [[Phalanges - Horse Anatomy#Distal Phalanx|distal phalanx]]

*'''Action''':  Extends [[Joints and Ligaments - Horse Anatomy#Thoracic Limb|carpus]] and digit

*'''Action''':  Extends [[Joints and Ligaments - Horse Anatomy#Thoracic Limb|carpus]] and digit

The common digital extensor tendon passes over the dorsolateral aspect of the [[Joints and Ligaments - Horse Anatomy#Thoracic Limb|carpus]] , continuing distally over the dorsal [[Joints and Ligaments - Horse Anatomy#Thoracic Limb|metacarpus]]. The branches of the interosseous muscle (suspensory ligament) join the common digital extensor tendon before its insertion on the extensor process of the [[Phalanges - Horse Anatomy#Distal Phalanx|distal phalanx]].  A minor branch inserts on the [[Phalanges - Horse Anatomy#Middle Phalanx|middle phalanx]] and some fibres insert on the [[Hoof - Horse Anatomy#Ungual Cartilages|hoof cartilages]]. The common digital extensor tendon is surrounded by the extensor retinaculum and a protective synovial sheath. The tendon sheath begins approximately 10cm proximal to the carpus, extending distally to the level of the [[Joints and Ligaments - Horse Anatomy#Thoracic Limb|metacarpus]].

*'''Origin''':  Lateral digital extensor muscle on the lateral [[Bones and Cartilages - Horse Anatomy#Humerus|humeral]]  epicondyle

*'''Insertion''': Dorsolateral aspect of [[Phalanges - Horse Anatomy#Proximal Phalanx|proximal phalanx]]

*'''Insertion''': Dorsolateral aspect of [[Phalanges - Horse Anatomy#Proximal Phalanx|proximal phalanx]]

*'''Action''': Extends the [[Joints and Ligaments - Horse Anatomy#Thoracic Limb|carpus]] and [[Joints and Ligaments - Horse Anatomy#Thoracic Limb|metacarpophalangeal]] joint

*'''Action''': Extends the [[Joints and Ligaments - Horse Anatomy#Thoracic Limb|carpus]] and [[Joints and Ligaments - Horse Anatomy#Thoracic Limb|metacarpophalangeal]] joint

The lateral digital extensor muscle arises from the lateral humeral epicondyle and forms the lateral digital extensor tendon on the lateral aspect of the antebrachium; caudal to the common digital extensor tendon. The tendon is enclosed within a synovial sheath as it extends distally over the [[Joints and Ligaments - Horse Anatomy#Thoracic Limb|metacarpus]] to insert on the dorsolateral aspect of the [[Phalanges - Horse Anatomy#Proximal Phalanx|proximal phalanx]].
