This series of brilliant photographs shows the dissection of the cat musculature. It is designed for use in conjunction with the third edition of Hyman's Comparative Vertebrate Anatomy, edited by Marvalee Wake, although it can be used with other textbooks. Every possible step has been taken to make the photographs easy to interpret and to follow. Reference indications to the Wake texts are included, and also concise data on the origin, insertion, and action of each muscle. The scale is such that in most cases no more than five muscles are shown per photograph, thus simplifying the task of visualizing the individual muscles. An invaluable aid for every student of cat anatomy.

CAT MUSCULATURE: A PHOTOGRAPHIC ATLAS

This guide coincides with the organization of the material in Hyman's Comparative Vertebrate Anatomy, third edition, edited by Marvalee Wake. Information on the origins, insertions, and actions of the muscles are also from Wake. Numbers following the names of individual muscles refer to plates in this atlas.

Pectoral Girdle and Forelimb Muscles

Superficial Chest Muscles (pages 355 and 356 in Wake)

Pectoantibrachialis 2, 15

Origin: Manubrium

Insertion: Fascia of forearm

Action: Draws arm towards chest

Pectoralis major 2, 15

Origin: Sternum and median ventral raphe

Insertion: Pectoral ridge on ventral side of humerus

Action: Draws arm towards chest

Pectoralis minor 2, 15

Origin: Sternum

Insertion: Ventral side of humerus, distal to pectoralis major

Action: Drawn arm toward chest

Xiphihumeralis 2, 15

Origin: Xiphoid process

Shoulder Muscles (pages 356 to 359 in Wake)

Latissimus dorsi 3

Origin: Neural spines of last thoracic and lumbar vertebrae and lumbodorsal fascia

Insertion: Medial surface of humerus

Action: Pulls forelimb dorsally and caudally, by retracting humerus

Trapezius muscles

Spinotrapezius 3

Origin: Spines of thoracic vertebrae

Action: Draws scapula dorsad and caudad Acromiotrapezius 3

Origin: Spines of cervical and first thoracic vertebrae

Insertion: Metacromion process, spine of scapula, and fascia of spinotrapezius

Action: Draws scapula dorsad and holds scapulae together

Clavotrapezius 3

Origin: Superior nuchal line and median dorsal line of neck

Insertion: Clavicle

Action: Draws clavicle dorsad and craniad

Levator scapulae ventralis 3

Origin: Transverse process of atlas and occipital bone

Insertion: Metacromion process of scapula and neighboring fascia

Action: Draws scapula craniad

Rhomboideus 4

Origin: Neural spines of vertebrae and ligaments

Insertion: Vertebral border of scapula

Action: Draws scapula dorsad and medial

Rhomboideus capitis 4

Origin: Superior nuchal line

Insertion: Scapula

Action: Draws scapula craniad or raises head Deltoids

Clavodeltoid (clavobrachialis) 3

Origin: Clavicle and fiber...
