Fun Facts About the Muscular SystemThe muscles in our body are responsible for keeping our heart beating and for all our physical movements. Here are some fun facts about the muscular system.• Muscle is a soft tissue in the body of humans and animals.
Its main purpose is to produce force and motion.• Muscles are responsible for maintaining posture, physical
movement (sitting, walking, eating, etc.), and movement of internal organs (such as keeping the heart pumping to circulate blood and moving food through the digestive system).
• The word muscle is derived from the Latin term musculus, meaning "little mouse". This Latin term could be due to theshape of some muscles or because muscles contracting under the skin can look like a mouse moving under a rug.
• Tendons connect our soft contracting muscle to our hard bones.
• There are around 650 skeletal muscles in the human body.• There are three types of muscle, skeletal, cardiac, and smooth.• Skeletal muscles (or striated) are voluntary muscles that
control nearly every action a person intentionally performs.• Tendons attach the muscle to two bones across a joint, as one
muscle contracts the other relaxes which moves the bones• Smooth muscle (or visceral) is involuntary, its not controlled
by our conscious mind. It is found on the walls of many organs and structures such as the esophagus, stomach, intestines, bladder, and blood vessels. Smooth muscles contract to movesubstances such as food through the organ.
• Cardiac muscle is also an involuntary muscle. It is only found in the heart and is responsible for keeping the heart pumping.
• Muscle makes up around half of the total human body weight. Muscle tissue is also around 15% denser than fat tissue.
• It takes 17 muscles in the face for us to smile and 43 muscles to frown.
• The tongue has 8 muscles, so is technically not the strongest muscle in the body.
• The heart cardiac muscle does the most work of any muscleover a lifetime

Use diagram #1 for the following questions.
1. What body system is represented in the diagram?
2. What is the main purpose of that body system?
3. How many muscles do you think there are in the human body?
1. Think of 5 different muscles in your bodyand list them on your labsheet. You don’t have to use the scientific name.
Muscles can be classified as voluntary, meaning you choose to move them, or involuntary, meaning they move on their own.
The function of the muscular system is to allow for movement within the body.
Without muscles our body could not move. There are approximately 640 muscles in the human body, and they work directly with the skeletal system to allow movement to happen.

1. On your lab sheet classify the muscles as either voluntary or involuntary.
©KeslerScience.com
Muscles are broken into 3 different types.
1. Cardiac – this is an involuntary muscle that controls your heartbeat
2. Smooth (visceral) – these involuntary muscles are found in your organs and perform unique functions like grinding or churning or moving
3. Skeletal – these are voluntary muscles thatyou physically have control over.

Use diagram #2 to help answer the followingquestion.
1. Categorize the muscles as either voluntary or involuntary. Then categorize it as cardiac, smooth, or skeletal.
You should have two terms for each muscle.

Biceps – when contracted the biceps are essential to the forearm for lifting
Deltoid - when all its fibers contract simultaneously, the deltoid is the prime
mover of arm abduction along the frontal plane
Pectoralis Major – often referred to as‘pecs’, these muscles are responsible for
moving the shoulder joint
External Oblique – responsible for pulling the chest downwards to compress the
abdominal cavity
Latissimus Dorsi - responsible for extension, abduction, transverse extension also known as
horizontalabduction, flexion from an extended position,
and(medial) internal rotation of the shoulder joint
Gluteus Maximus – regarded as one of the strongest muscles in the body.
Responsible for movement of hip and thigh
Gastrocnemius - Its function is plantar flexing the foot at the ankle joint and
flexing the leg at the knee joint.
Biceps Femoris - Both heads of the biceps femoris perform knee flexion
