  6. 6. 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
  7. 7. 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.

  8. 8. 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
  9. 9. 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
  10. 10. 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
  11. 11. 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.

  12. 12. 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
