Cat skeletal muscle General hint: muscles can be tough to ID. If you are having trouble, look through the pictures for that section of the animal and find the easiest one to identify. Then look for the relationship of your difficult muscle to the easy one. Works for me anyway. 1. Phylum Chordata Subphylum Vertebrata Superclass Gnathostomata Class Mammalia Be able to identify the following: Superficial musculature Platysma/cutaneous maximus Head and Neck Masseter Mylohyoid Digastric Geniohyoid Hyoglossus Sternohyoid Thyrohyoid Temporalis Neck and Pectoral region Sternomastoid Clavobrachialis Pectoralis minor Spinodeltoid Latissimus dorsi Triceps (long/lateral) Cleidomastoid Levator scapulae Splenius Infraspinatus Brachialis Scalenes (ant., med.,post.) Rhomboideus Coracobrachialis Clavotrapezius Pectoralis major Acromiotrapezius Spinotrapezius Epitrochlearis Clavobrachialis Rhomboideus capitis Acromiodeltoid Supraspinatus Teres major Subscapularis Pectoantebrachialis Teres minor Notice that the cat pectoralis major and minor are homologous with portions of the necturus pectoralis. This occurs in many limb and girdle muscles, one muscle evolving into two. How does this relate to locomotion in this case? Forelimb Brachioradialis E. digitorum communis E. carpi ulnaris F. Carpi ulnaris Pronator teres E. Carpi radialis longus E d. lateralis Abductor pollicis longus Biceps brachii F. digitorum profundus F. carpi radialis F. digitorum superficialis Serratus ventralis External abdominal oblique Back Abdomen External abdominal oblique Internal abdominal oblique Transversus abdominis Rectus abdominis Ext./int. intercostal Pelvic region and proximal hindlimb Sartorius Gluteus maximus Biceps femoris Caudofemoralis Semitendinosus Gluteus medius Vastus lateralis Semimembranosus Rectus femoris Vastus intermedius Gracilis Adductor longus Adductor femoris Vastus medialis Iliopsoas Pectineus Tensor fascia latae Distal hindlimb Tibialis anterior Extensor digitorum longus Peroneus group Peroneus tertius Gastrocnemius Tibialis posterior Flexor digitorum longus Check out p. 114-115 of Kardong: Homologies are drawn for several muscles. Be very familiar with these.
