Dorsal Muscles

In cats there are three muscles on each side of the dorsal thorax: the clavotrapezius, acromiotrapezius, and spinotrapezius. In humans these three muscles are represented by one muscle, the trapezius.

The clavotrapezius is the most cephalad of the group in the cat. This muscle joins with the clavodeltoid. The acromiotrapezius lies superficial to the scapula. The spinotrapezius is a triangular muscle extending caudally down the vertebral column.

There is one large muscle on each side of the lower back, the latissimus dorsi. This muscle wraps around the side of the body to partially cover the external oblique and the pectoralis group.
