Muscle is a soft tissue found in most animals. Muscle cells contain protein filaments of actin and myosin that slide past one another, producing a contraction that changes both the length and the shape of the cell. Muscles function to produce force and motion There are three types of muscle, skeletal or striated, cardiac, and smooth. Muscle action can be classified as being either voluntary or involuntary. Cardiac and smooth muscles contract without conscious thought and are termed involuntary, whereas the skeletal muscles contract upon command.

3. MUSCULAR SYSTEM
The muscular system is an
organ system consisting of
skeletal, smooth and cardiac
muscles.

4. Muscular System permits movement
of the body, maintains posture and
circulates blood throughout the body
Muscles provide strength, balance,
posture, movement and heat for the
body to keep warm..
PURPOSE

6. Skeletal muscle
Skeletal muscle is a specialized contractile tissue found in
animals which functions to move an organism’s body.
Skeletal muscle is comprised from a series of bundles of
muscle fibers, surrounded by protective membranes
This arrangement allows skeletal muscle to contract
quickly and release quickly without subjecting the
individual fibers to too much friction
Skeletal muscle tissue can be found across the
animal kingdom, in most multi-cellular forms of life.

9. CARDIAC MUSCLE
It is one of the three main types
of muscle in vertebrates
It is involuntary: a person cannot control it
consciously
Also, it is a striped muscle in the walls of
the heart
It makes up the tissue called the
myocardium.

11. FUNCTIONS OF CARDIAC
MUSCLE
Cardiac muscle tissue works to keep
your heart pumping through involuntary
movements
This is one feature that differentiates it
from skeletal muscle tissue, which you can
control
It does this through specialized cells
called pacemaker cells
These control the contractions of
your heart.

12. SMOOTH MUSCLE
Smooth muscle, also called
involuntary muscle, muscle that shows no
cross stripes under microscopic
magnification
It consists of narrow spindle-shaped cells
with a single, centrally located nucleus.
Smooth muscle tissue, unlike
striated muscle, contracts slowly and
automatically.

FUNCTIONS OF SMOOTH MUSCLES
Smooth muscles move food through the
digestive tract
In one's eye the pupillary
sphincter muscles is responsible for
shrinking the size of the pupil
In arteries, smooth muscle movements
maintain the arteries' diameter
Smooth muscle regulates air flow in lungs.
