Skeletal muscle, striated in structure and under
voluntary control, is anchored
by tendons to bone and is used to
effect skeletalmovement such as locomotion and
to maintain posture. An average adult male is
made up of 42% of skeletal muscle and an
average adult female is made up of 36% (as a
percentage of body mass). It also has striations
unlike smooth muscle.

5. SMOOTH MUSCLE & CARDIAC

nor under voluntary control, is found within the
walls of organs and structures such as
the esophagus, stomach, intestines,bronchi, u
terus, urethra, bladder, blood vessels
 Cardiac muscle (myocardium), found only in
the heart, is a striated muscle similar in
structure to skeletal muscle but not subject to
voluntary control.
