Neck and Throat
The Rhomboideus Capitis is the muscle lateral to the Rhomboideus Cervicis on the upper spine of the pig. This muscle helps elevate and rotate the scapula.
The Rhomboideus Cervicis is the most medial muscle of the the three in the video and helps elevate the forelimb. The Splenius lies just deep to the Capitis and the Cervicis. It helps the pig raise and turn its head. |

The deltoid is a superficial muscle. Covering most of the scapula region, this muscle is only present as a few muscle fibers in the fascia that covers the shoulder area. This muscle is underdeveloped in most fetal pigs so if it appears to be developed, it is most likely either the supraspinatus or infraspinatus muscles.

Deltoid
The Sternohyoideus is the most superficial of the three muscles shown and is also the most medial to the ventral side of the pig. These muscles are all found in the front part of the pigs neck where the Cervicis, Capitis, and Spleneus are all on the back part.
The Sternothyroideus is found just deep to the Sternohyoideus and is very skinny. Its noticably smaller than the Sternohyoideus. The Sternomastoideus is the most lateral of the three muscles and helps to flex and rotate the head. |

The Masseter is the muscle that lies on the cheek of the pig's face. It helps open and close the jaw allowing the pig to chew food and
To expose the Masseter, cut the skin from the side of the face and the upper neck. |
