Muscular Responses and Interactions

The minimal strength required to cause a contraction is called the __________________________ stimulus

The resulting pattern created by muscle stimulation is called a

• myogram

• twitch

• all or none response

• latent period

Skeletal muscle fibers normally do not contract partially, if it contracts at all it contracts completely

• myogram

• twitch

• all or none response

• latent period

A single contraction that lasts a fraction of a second

• myogram

• twitch

• all or none response

• latent period

The pause between stimulus and muscle contraction is called the______________________.

• myogram

• twitch

• all or none response

• latent period

The result of summation is a forceful, sustained contraction lacking partial relaxation is called _________________ contraction

• origin

• insertion

The movable end of a muscle is called its

• origin

• insertion

The muscle doing most of the moving in a muscle group to complete a body movement
