Muscles Named by Shape deltoid – triangle Latissimus – wide teres - round trapezius – trapezoid serratus –saw-toothe orbicularis – circular Muscles Named for Origin and Insertion Points sterno = sternum cleiodo = clavicle mastoid = location on the temporal bone sternocleiodomastoid muscle...
Each muscle is given a specific name based on its location, shape, action, or attachment points. For example, the sternocleidomastoid muscle gets its name from its attachments to the sternum, clavicle, and mastoid process. The gluteus maximus is named for its location and ...

Skeletal muscles could be named according to their location, origin, and insertion, number of origins, shape, size, direction, and function. Location— muscles derive their names according to their anatomical region. For example, the rectus abdominis and transversus abdominis are found in the ...
Skeletal muscles are named in different ways: Some are named depending on their location, some depending on their origin or insertion, some based on the number of origins of a single muscle and others on basis of their direction and function. Smooth Muscles These are also called as involuntary...
The muscles are known as vastus lateralis, vastus intermedius, vastus medialis, and rectus femoris muscles. The function of these muscles is to extend the knee and stabilize the knee bone or patella. The rectus femoris muscle also helps to flex the thigh at the hip. This muscle is named "...
There are other muscles throughout the body named by their shape or location. The deltoid is a large, triangular-shaped muscle that covers the shoulder. It is so-named because the Greek letter delta looks like a triangle. The rectus abdomis (rector = “straight”) is the straight muscle ...
Each skeletal muscle is an organ and is named. The names may seem strange but they contain information about the muscle. The name may indicate the location of the muscle in the body (femoris, brachii), the shape of the muscle (deltoid, trapezius), its action (adductor, pronator) or its...
Explain how muscles are named and give examples What is the action of the pectoral muscle in a chest press? (a) Where is the gluteus medius located? (b) Explain its action. What is the relationship between a muscle workload and its threshold of stimulation?
Origin: Middle part of lateral border of the scapula Insertion: Inferior aspect of greater tubercle of humerus Functions: Laterally rotates and adducts (moves toward the body) the upper arm and helps stabilize the upper arm in the shoulder by drawing it toward the scapula ...
