Fun Facts About the Muscular System

The 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 the

shape 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 move

substances 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 muscle

over a lifetime

The main purpose of the muscular system is to .

A. Lift heavy things

B. Allow for movement

C. Allow for structure

D. Rid the body of unwanted waste

KeslerScience.com

What is the purpose of tendons?

A. They attach to our internal organs to control breathing and heartbeat

B. They connect nerves to muscles

C. The connect muscles to organs

D. They attach the muscle to two bones and allow for movement

KeslerScience.com

Which type of muscle controls our digestive system?

Why do people say its easier to smile than frown?

A. Smooth (visceral)

B. Cardiac

C. Digestive

D. Skeletal

KeslerScience.com

A. We are often more happy than sad

B. More muscles are used in smiling

C. We use less muscles to smile

D. Frowning causes muscular problems

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. (KeslerScience.com)How many muscles do you think there are in the human body?

1. Think of 5 different muscles in your body

and list them on your lab

sheet. You dont 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.

KeslerScience.com

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 that

you physically have control over.

question.

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 horizontal

abduction, 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
