What are examples of fusiform muscle?

Fusiform muscles are characterized by a spindle-like shape, with a central belly that tapers at both ends. Examples include the biceps brachii, which flexes the elbow, and the brachialis, which assists in elbow flexion. Another example is the sartorius, the longest muscle in the human body, which aids in hip and knee flexion. These muscles are efficient for producing movement due to their arrangement of fibers.
