|
|
|
Fascicles that run parallel to the long axis of a muscle
|
|
|
Examples Include the Satorius
|
|
|
The fibres are short, attaching obliquely to become a central tendon that runs the full length of the muscle
|
|
|
Are Strap like
|
Detailed explanation-1: -There are three types of parallel muscles: Strap muscles, that have a narrow belt-like or strap-like belly; for example the sartorius muscle of the thigh. Fusiform muscles, with a spindle-shaped and extended belly, like the biceps brachii muscle of the arm.
Detailed explanation-2: -Fusiform muscles These are strap-like and occur where muscle fibres lie parallel to each other and a tendon occurs at either end of the muscle belly. They have fewer fibres that are longer, but cannot achieve as great a force as pennate muscle shapes (although they can generate a higher limb velocity).
Detailed explanation-3: -Parallel muscles have fibres that, as the name suggests, run parallel to each other and are sometimes called strap muscles. They are normally long muscles which cause large movements, and are not very strong but have good endurance. Examples include Sartorius and Sternocleidomastoid.
Detailed explanation-4: -The biceps brachii is an example of a fusiform parallel muscle, and is responsible for flexing the forearm.
Detailed explanation-5: -Fusiform muscles are those in which all the muscle belly fibers are arranged parallel to each other. An example of the fusiform muscle is m. biceps brachii.
