1 Advanced Cat Muscles The next exam is worth 120 points!

2 Sternocleidomastoid Pectoralis major Serratus anterior Rectus abdominis External oblique Deltoid Pectoralis minor Superficial Chest Human:

3 Pectoantebrachialis **no homolog in humans 2 Pectoralis major 3 Pectoralis minor Xiphihumeralis **no homolog in humans

4 DeepSuperficial Levator scapulae Teres major Trapezius Deltoid Latissimus dorsi Human:

5 Superficial back Teres minor Rhomboid minor Rhomboid major Latissimus dorsi Deltoid Long head triceps Trapezius

6 Superficial Shoulder, Back, & Forelimb Latissimus Dorsi Spinotrapezius Acromiotrapezius Clavotrapezius Levator Scapulae Ventralis Spinodeltoid Acromiodeltoid Clavodeltoid Triceps brachii Lateral Head Triceps brachii Long Head Group VI Head 

7 Levator scapulae dorsalis (9) is like a thin ribbon that sits on top of splenius (10), which is the thick muscle underneath. Spinalis dorsi (15) is a sheet of muscles that run along the side of the vertebral column UNDERNEATH latissimus dorsi. You have to cut one of the latissimus dorsi flaps and lift it up to see spinalis dorsi. Just learn “Rhomboideus” or “Rhomboids” (11-12) for the cat, but in cadaver you need to specify Rhomboidius major vs. minor.
