This document discusses different types of muscles in the body. It describes circular muscles that surround openings like the mouth. Convergent muscles have a wider origin point than insertion point, like the deltoid muscle. Parallel muscles cause large movements and have parallel fibers, like the teres major. Pinnate muscles resemble feathers and can be unipinnate, bipinnate, or multipinnate in their fiber arrangement. Unipinnate muscles have diagonal fibers inserting on a tendon. Bipinnate muscles have two rows of diagonal fibers facing opposite directions. Multipinnate muscles have multiple branching tendons. Fusiform muscles are spindle-shaped like the biceps brachii. The document provides examples

- 7. Convergent Muscle These are muscles where the origin (the attachment to a fixed bone, usually the proximal attachment) is wider than the point of insertion. A large triangular muscle that covers the shoulder joint and serves to raise the arm laterally (deltoid) Free powerpoint template: www.brainybetty.com 7
- 8. Parallel Muscle They are normally long muscles which cause large movements and have parallel fibers and broad attachments (Teres major). Sometimes called strap muscles or Fusiform muscles . Examples include Sartorius and Sternocleidomastoid. Free powerpoint template: www.brainybetty.com 8
- 9. Pinnate Muscles Pinnate muscles have a large number of muscle fibers per unit and so are very strong, but tire easily. Resembling a feather especially in having similar parts arranged on opposite sides. They can be divided into three; Unipinnate, Bipinnate and Multipinnate: Free powerpoint template: www.brainybetty.com 9
- 10. Unipinnate These muscles have their fibers arranged to insert in a diagonal direction onto the tendon, which allows great strength. Examples include the Lumbricals and Extensor Digitorum Longus. Free powerpoint template: www.brainybetty.com 10
- 11. Bipinnate Bipinnate muscles have two rows of muscle fibers, facing in opposite diagonal directions with a central tendon, like a feather. This allows even greater power but less range of motion. An example is the Rectus Femoris Free powerpoint template: www.brainybetty.com 11
- 12. Multipinnate As the name suggests Multipinnate muscles have multiple rows of diagonal fibers, with a central tendon which branches into two or more tendons. An example is the Deltoid muscle which has three sections, anterior, medius and posterior. Free powerpoint template: www.brainybetty.com 12
- 13. Fusiform Muscle These muscles are more spindle shaped, with the muscle belly being wider than the origin and insertion. Sometimes included in the parallel muscle group, Examples are Biceps Brachii and Psoas major Free powerpoint template: www.brainybetty.com 13
