The extensor digitorum longus muscle has a parallel fascicle arrangement where muscle fibers run parallel to the long axis of the muscle. This arrangement allows the muscle to generate a strong pulling force to extend the toes.
Multipennate.
The rectus femoris muscle has a parallel fascicle arrangement, meaning its muscle fibers run parallel to the long axis of the muscle. This arrangement allows for strong contraction forces and efficient movement.
Parallel
Perimysium
They are called circular. Examples include the orbicularis oris and orbicularis oculi.
The fascicles are short and attach obliquely to a central tendon that runs the length of a muscle.
A fascicle is a bundle of muscle fibers within a skeletal muscle. These fascicles are surrounded by connective tissue called perimysium. The arrangement of fascicles within a muscle contributes to its overall structure and function, allowing for coordinated movement and strength.
