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

6. Circular Muscle
• Also known as sphincter muscles which surround an
opening such as the mouth, surrounded by Obicularis
Oris and Obicularis Oculi surrounding the eyes.

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)

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.

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:

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.

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

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.

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
