Linea Alba It’s The “White Line” That Runs The Length Of the Thorax and Abdomen - The Linea Alba Serves As a Site of Separation of Bilaterally Symmetric Muscles!

Using your mall probe, tease it away from surrounding muscle. Epitrochlearis Using your mall probe, tease it away from surrounding muscle.

Triceps - Long Head Note: The Epitrochlearis is cut and reflected to reveal the long head of the triceps brachii.

Latissimus Dorsi (7)

The Trapezius Group In man, the trapezius is one muscle. In a cat, the trapezius is subdivided into three muscles: Spinotrapezius Acromiotrapezius Clavotrapezius

Spinotrapezius Note that the spinotrapezius is shaped like a triangle!

Acromiotrapezius A very thin muscle that overlies the supraspinatus.

Clavotrapezius

The Deltoid Group In man, the deltoid is one muscle. In a cat, the deltoid is subdivided into three muscles: Spinodeltoid Acromiodeltoid Clavobrachialis (Clavodeltoid)

#5 Is The Brachioradialis! NOTE: The cat is lying on its back! #5 Is The Brachioradialis!

Flexor Carpi Radialis #9 is the Flexor Carpi Radialis!

Palmaris Longus It’s #10 to the right - the broadest, easiest to locate of the flexors!

Flexor Carpi Ulnaris #11 to the right, it is the flexor that overlies the ulna. Run a pin into it and leave it as a point of reference - we’ll use it in identifying the extensors.
