Overall Function of the System
http://www.innerbody.com/image/musfov.html
The main function of the muscular system
is movement. Muscles are the only tissue in the
body that has the ability to contract and
therefore move the other parts of the body.
The muscular systems second function: the
maintenance of posture and body position.
Organs in the System
● smooth muscular tissue - the tissues that line the blood vessels and organs such as
the stomach. not connected to the bones and are controlled by the autonomic
system.
●
skeletal muscles - helps hold the skeletal frame together, provides strength and
mobility, and allows humans to walk upright. skeletal muscles are the most well
known and familiar of muscles organ systems. some of the most common muscles
in the body are the abdominals, pectorals, booty, and quadriceps. each of these are
connected to tendons, ligaments, or skeletal tissues.
●
cardiac muscle - made up of the heart which is 1 out of 650 muscles found in the
human body. the heart is also one of the strongest muscles and beats at an average
of 72 times per minute. the heart is made up of cardiac tissues and is one of the
most muscular organs in the body.
Function of Individual Organs
Within the System
Smooth Muscular Tissue - A muscle that controls itself and a person has no control over it which
means mobility is involuntary
Muscles are not connected to bones
Smooth muscle tissue pushes food along the digestive tract and controls the flow of blood through
blood vessels.
Skeletal Muscles - Provide extension and contraction movements to the limbs, provide strength
and support for the body, protect our internal organs and enable us to walk, jump, sit, run and
carry.
Cardiac Muscle ( Heart Muscle ) - The heart is made up exclusively of cardiac tissues and is one
of the most muscular organs in the body, beating at an average of 72 times per minute
Individual Cells, Enzymes, and Hormones
Hormones:
➢Growth Hormone
○ Cause of growth stimulation
➢Insulin
Growth
○ Your body uses sugar (glucose) from carbohydrates in food that you consume for energy
Hormone
or to store glucose for future use
Cells:
➢Cardiac Muscle Cell

Interaction with two Other Systems
Skeletal System:
Receptors in muscles provide the brain with information about body position
and movement. The brain controls the contraction of skeletal muscle.
Nervous System:
The nervous system regulates the speed at which food moves through the
digestive tract.
