Types Of Skeletal Muscles

Question 1

These are fan-like muscles. The fascicles are broad at the origin and taper to a narrow intersection. This arrangement functions to concentrate the force of the muscle contraction into a smaller area.

Answer 1

Convergent

Question 2

The fascicles are attached to a tendon in a feather-like manner. The tendon is the shaft of the feather and the fascicles are the bane.
3 types:
A) The fascicles are attached to one side of the tendon.
B) The fascicles are attached to both sides to the tendon.
C) The fascicles converge on a branching tendon.

Answer 2

Pennate.

A) Unipennate muscle

B) Bipennate muscle

C) Multipennate muscle

Question 3

These are sphincter muscles. The fascicles surround an opening. The action of the muscle increases or decreases the diameter of the opening.

Answer 3

Circular.

Question 4

The fascicles are parallel to the long axis of the muscle. They are generally long strap like muscles that can generate much force. The strongest of these muscles are fusiform in shape. That is, they are wide in the middle and taper at each end.

Answer 4

Parallel
