Descending superficial pectoral = 1st sternebrae Transverse superficial pectoral = 1st, 2nd, 3rd sternebrae, raphe Brachiocephalicus = Clavicular intersection Omotransversarius = Distal end of scapular spine

Superficial pectoral = Crest of the greater tubercle of the humerus Cleidobrachialis = Brachium Cleidocephalicus pars mastoidea = Mastoid process of the temporal skull bone Cleidocephalicus pars cervicalis = Dorsal midline of the neck

Superficial pectoral = Adduct limb when weight bearing; prevent abduction when not Deep pectoral = Pull trunk cranially, extend shoulder when limb is advanced; pull limb caudally, flex shoulder when not Brachiocephalicus = Advance limb, extend shoulder, draw head and neck to the side Omotransversarius = Advance limb, flex neck laterally
