Cadaver sketches: Deep back muscles and Dorsal Scapular Nerve
The diagrams above show muscles in the mouth area that are not strictly speaking muscles of facial expression. There are more muscles in these areas than illustrated here. Top: Pterygoids and Hyoids. 2nd: Pterygoids. 3rd: Pterygoids from inside jaw. Last: Hyoids and hyoid bone.
The Pterygoid muscles, internal and external, are muscles of mastication and function to position the jaw. The Mylohyoid and Geniohyoid help position the hyoid bone and larynx, and are important in swallowing.
Dissection of the neck, shoulder and axilla.
By Joseph Maclise
Dissection of the neck, shoulder and axilla, deep dissection, shown in 2 numbered illustrations. 1 illustration showing thoracic and shoulder muscles divided to show brachiocephalic vein, axillary artery, brachial plexus, and axillary lymph nodes. Male cadaver, in vivo, anterior view. 1 illustration of dissection of axilla shown in isolation, showing brachiocephalic veins, axillary artery and axillary lymph nodes. Anterior view.

Muscle attachments of the human skull. Origins are in red and insertions are in blue.
The attachment of a muscle is the place where it is connected to a tissue, usually on a bone. The fixed place of attachment is also known as the origin. These diagrams show some insertions, which is a place where the muscle goes to and which the muscle moves. In facial muscles, most insertions are into skin tissues, but some insert into bone, e.g., the masseter. The action of the muscle is to pull the skin where the muscle inserts toward the origin.
