Origin, Insertion & Supply

OriginSuperior medial end of one clavicle
InsertionSuperior medial end of the opposite clavicle, spanning the jugular notch
Biomechanics

Function & Actions

ActionsConnects the two clavicles across the jugular notch; assists in SC joint stabilisation against inferior clavicular displacement
