Forelimb Muscle Flashcards
Cutaneo trunci or panniculus twists skin
O; subcutaneous fascia - white connective tissue sheets
I; the skin of the trunk
Synarcosis
Forelimb attached onto side of thorax by muscles alone, it is an articulation at the truncobrachial junction, cursorily specialisation
Panniculus reflex
Reflex of the cutaneous trunci to twitch the skin, locates damage to the spinal cord
latissimus dorsi
O; Spinous process of trunk vertebrae (caudal 2 or 3 ribs)
I; Teres tuberosity medial of humerus
F; Prime retractor of the forelimb
Brachiocephalicus = protactor
Cleidomastoideus
cleidocervicalis
cleidobrachialis
o; skull
o; raphe of neck
i; distal third of humerus shaft
omotransversarius
