Muscles & Bones
Muscles

a tissue composed of bundles of elongated
cells capable of contraction and relaxation
to produce movement in an organ or part
Types of Muscle

Cardiac

Skeletal

Smooth
Smooth Muscle
-
-
The muscle is smooth and NOT striated
Located in the tunica media layer of large
and small arteries and veins, the bladder,
uterus, male and female reproductive tracts,
gastrointestinal tract, respiratory tract, the
ciliary muscle, and iris of the eye
This type of muscle is involuntary
Controls movement in internal organs
Cardiac Muscle
- is a type of involuntary striated muscle
found in the walls of the heart. As it
contracts, it propels blood into the heart
and through the blood vessels of the
circulatory system.
Skeletal Muscle
- most common of the three types of
muscle in the body. Striated muscle is
attached to bone and produces all the
movements of body parts in relation to
each other
- Found throughout the body
- Examples – Pectoralis Major, Quadriceps,
Biceps, Triceps, etc.
- This type of muscle is
Voluntary

BONES


the hard connective tissue forming the
substance of the skeleton of most vertebrates,
composed of a collagen-rich organic matrix in
fused with calcium, phosphate, and other
minerals.
Review: Tendons are tough inelastic bands that
hold and attach muscle to bone. Tendons allow
your muscles to move your bones!
Purpose of Bones in the Body



The main job of the skeleton is to provide
support for our body. Without your
skeleton your body would collapse into a
heap. Your skeleton is strong but light.
Without bones you'd be just a puddle of
skin and guts on the floor.
There are 206 bones in your body!
Newborn babies have over 300 bones,
these bones fuse together to make 206
when they get older
Purpose Cont…



Your skeleton also helps protect your internal
organs and fragile body tissues
The brain, eyes, heart, lungs and spinal cord
are all protected by your skeleton.
Your cranium (skull) protects your brain and
eyes, the ribs protect your heart and lungs and
your vertebrae (spine, backbones) protect your
spinal cord.
Breaking Bones



Bones are tough and usually don't
break even when we have some
pretty bad falls.
Bones will bend a little, but if you fall the
wrong way from some playground
equipment or maybe your bike or
skateboard you can break a bone.
Doctors call a broken bone a
fracture.
Healing



Bones are made of living cells.
When a bone is broken your bone will
produce lots of new cells to rebuild the bone.
These cells cover both ends of the broken
part of the bone and close up the break.
Strengthening your Bones

Strengthen your skeleton by drinking milk
and eating other dairy products (like lowfat cheese, frozen yogurt, and ice cream).
They all contain calcium, which helps
bones harden and become strong.

Activity 2 – Tape Skeleton




Get into groups of 3
Materials: 1 big sheet of paper, 1 roll of
tape, 1 pen/pencil
Your group is to create a skeleton out of
tape and tape it on the sheet of paper.
You are to label each individual bone.
How do you keep your bones
healthy?



Bones need regular exercise to stay as strong as
possible. Walking, jogging, running and other
physical activities are important in keeping your
bones strong and healthy.
Riding your bike, basketball, soccer, gymnastics,
baseball, dancing, skateboarding and other
activities are all good for your bones.
Make sure you wear or use the proper
equipment like a helmet, kneepads, shin guards,
mats, etc... to keep those bones safe.
Bones Song





Get into groups of 3 or 4
Your group is to create a song or rap about the
bones
This activity is to help you remember the names
of the bones and where they are on your body.
At least one member of your group will have to
perform the song for the class.
You will need at least one person to record the
lyrics of the song on a sheet of paper to turn in.
Activity 1: Labeling the Bones
Activity






Get into Groups of 3 or 4
Gather 1 roll of tape & small sheets of paper
In your group you will need 1 model, and 2 or 3
labelers
You are to label each bone on the body on your
model
When you are done raise your hand so the
teacher can check the model
Remember: DO NOT touch any model in their private
parts, if you do you will be sent to the office, given a
referral, and ALL of your points will be lost for the day
