Muscles with Fibers That Run at an Angle to the Long

Question

Muscles with fibers that run at an angle to the long axis of the body are called
A)parallel.
B)convergent.
C)circular.
D)pennate.
E)sphincters.

Accepted Answer

Muscles with fibers that run at an angle to the long axis of the body are called pennate. Pennate muscles have shorter fibers than parallel muscles and therefore produce less range of motion but greater force. Examples of pennate muscles include the gastrocnemius in the calf and the deltoid in the shoulder.
