synatsis of collagen, elastin, and reticular fibers.
forming tendons and at fascia that covers muscles.
D) filling spaces between tissues to keep organs in place.
10 Although all muscle tissue cells have some similarities, smooth muscle (also
. known as involuntary muscle) differs by:
A) having dense bodies attached to actin filaments.
B) containing sarcomeres between Z lines and M bands.
C) having rapid contractions and abundant cross-striations.
D) contracting in response to increased intracellular calcium.
