There are three main types of muscle in the human body: skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle is striated, attached to bones by tendons, and under voluntary control. It allows for movement and posture. Smooth muscle is found within internal organs and structures like the stomach, intestines, and blood vessels. It is involuntary and not striated. Cardiac muscle makes up the heart and is striated but not voluntarily controlled.

2. INVOLUNTARY MUSCLES
involuntary muscle - a muscle that contracts
without conscious control and found in walls of
internal organs such as stomach and intestine
and bladder and blood vessels (excluding the
heart) smooth muscle.

4. SKELETAL MUSCLE
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
MUSCLE
 Smooth muscle, neither striated in structure
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.
