Muscular System
Muscular System- is an organ system consisting of skeletal muscle. It
move the body and circulates blood throughout the body
There are four type of muscles: Skeletal muscles, cardiac or heart
muscle, and smooth muscle.
Muscles provide strength, balance, posture, movement and heat for
the body to keep warm.
Cardiac muscles
Cardiac muscle- the muscle tissue of the heart
 Heart muscles are distinct from skeletal muscles because the
muscle fibers are connected to each other. Furthermore, just as
with smooth muscles, they are not controlling themselves. Heart
muscles are controlled by the sinus mode influenced the
autonomic nervous system.
 Unlike other types of muscle, cardiac muscle never gets tired. It
work automatically without ever pausing to rest.
Smooth muscle
 Smooth muscle- is found in the walls of hollow organs
like your intestines and stomach
 Smooth muscles are also found in the bladder.
 When someone goes to the bathroom, they contract,
which pushes urine out of the bladder.
Skeletal muscles
Skeletal Muscle- produces movement, maintains posture, stabilises
joints and generates heat.
Skeletal muscle tissue is the most common thought of as muscle.
Skeletal muscle are soft and fragile. Each organ or muscle consists of
skeletal muscle tissue, connective tissue, nerve tissue, and blood or
vascular tissue.
Muscular system quiz
 1.TRUE OR FALSE
Each muscle has two endings that attach to the other structures (such as
bone or soft tissue) and they are categorized according to their role in
movement.
 2.TRUE OR FALSE
Muscles shorten during manual control, causing soft tissue and bony
structures to move.
3.TRUE OR FALSE
In some bones, moving point could be at either end.
 4.TRUE OR FALSE
These muscles work with the TMJ to accomplish movement of the
mandible
Answer to the Muscular quiz
 1.TRUE
 2.TRUE
 3.TRUE
 4.TRUE
