Study Notes
Naming Skeletal Muscles
- Muscle names reveal various attributes such as fiber direction, location, size, number of origins, shape, origin and insertion, and action.
Fiber Directions
- Rectus fibers are oriented parallel to the body's midline.
- Transverse fibers are aligned perpendicular to the midline.
- Oblique fibers run diagonally to the midline.
Location-Based Muscle Names
- Temporalis muscle is located near the temporal bone.
- Tibialis anterior is situated at the front of the tibia.
Size Indicators in Muscle Names
- Maximus denotes the largest muscle.
- Minimus signifies the smallest muscle.
- Longus refers to a long muscle.
- Brevis indicates a short muscle.
Number of Origins
- Biceps Brachii has two origins.
- Triceps Brachii consists of three origins.
- Quadriceps Femoris is characterized by four origins.
Shape-Related Names
- Deltoideus describes a triangular shape.
- Trapezius indicates a trapezoid shape.
- Serratus denotes a saw-toothed appearance.
- Rhomboideus refers to a rhomboid or diamond-shaped structure.
Origin and Insertion Naming
- Sternocleidomastoid originates on the sternum and clavicle and inserts on the mastoid process of the skull.
- Styloyoid starts at the styloid process of the skull and inserts on the hyoid bone in the neck.
Action-Based Muscle Names
- Flexor carpi radialis denotes a muscle that flexes the wrist.
- Pronator teres refers to a muscle that pronates the hand.
