Cutaneous Trunci |
Attachment - Superficial fascia of trunk and skin (covers entire thoracic and lumbar region) Action - Twitches Skin |
|
|
Superficial Transverse and Descending Pectoralis |
Attachments -
Origin: Cranial 2-3 sternebrae Insertion: Greater tubercle of the humerus Action - Adduction (moves limb forward w/out weight) Agonist - Deep Pectoralis Innervation - cranial pectoral nerves |
|
|
Deep Pectoral |
Attachment - Origin: ventral sternum Insertion: lesser tubercle of the humerus (medial side) Action - Ambulation/walking or digging Innervation - caudal pectoral nerves Agonist: Superficial Pectorals Antagonist: Brachiocephalicus |
|
|
Brachiocephalicus |
Attachment -
Origin: Mastoid Process and nuchal crest (skull) Insertion: Proximal cranial surface of the humerus Action - w/ weight: flexes head laterally w/o weight: extends and advances the limb Antagonist - Deep Pectoralis Agonist - Cleidocephalicus Innervation - accessory nerve |
|
|
Sternocephalicus (Attachments) |
Attachments -
Origin: First cranial sternebrae Insertion: Mastoid process, nuchal crest Action - w/ weight: flexes head down w/o weight: same Innervation - accessory nerve and ventral branches of cervical spinal nerves |
|
|
Sterno-thyro-hyoideus |
Attachment - Origin: First cranial sternebrae Insertion: Thyroid cartilage and hyoid apparatus Action - w/ weight: pulls down base of tongue, opens esophagus, lowers thyroid cartilage Innervation - ventral branches of cervical spinal nerves |
|
|
Omotransversarius |
Attachment - Origin: Wing of atlas Insertion: Middle distal third of scapula spine Innervation - Accessory nerve Action - w/ weight: flexes neck laterally w/o weight: ambulation, brings limb cranially Innervation - Accessory nerve |
|
|
Trapezius |
Attachment - Origin: Median raphe to nuchal crest Insertion: Dorsal cranial spine of scapula Innervation - Accessory nerve Action - w/ weight: elevates scapula when walking w/out weight: Abducts limb Innervation - Accessory nerve |
|
|
Rhomboideus |
Attachment - Origin: Median raphe and nuchal crest Insertion: Inside cranial scapula border Action - w/ weight: depresses scapula and elevates it with the trapezius w/o weight: Abducts limb Innervation - Ventral branches of the cervical and thoracic spinal nerves |
|
|
Latissimus dorsi |
Attachment - Origin: Lateral aspect of the ribs Insertion: Teres major tuberosity Action - w/ weight: brings body forward, ambulation w/o weight: draws limb joint caudally Innervation - thoracodorsal nerve |
|
|
Serratus ventralis |
Attachment - Origin: Lateral aspect of the ribs, more ventral than the rhomboideus Insertion: Cervical vertebrae, serrated face of the scapular Action - anti gravity in quadrupeds, attaches limb to the body Innervation - Ventral branches of cervical spinal nerves and the long thoracic nerve |
|
|
Pectoro-antebrachialis (cats only) |
Attachment - Origin: lateral surface of manubrium Insertion: fascia of forearm Action - w/o weight: adduct limb (swatting) |
