joints
The point where two bones meet and connect is called joint.

Our joints and muscles allow our bones to move.
The movements of our body originate in our joints.
Marie Jaja T. Roa- SANTA MARIA WEST CENTRAL SCHOOL- Division of Ilocos Sur
Muscles form the fleshy parts of the body.They enable our body to move.
Marie Jaja T. Roa- SANTA MARIA WEST CENTRAL SCHOOL- Division of Ilocos Sur
Muscles expand and contract to help bones move.

They also give shape and forms to our body and protect delicate organs.
Muscles are voluntary or involuntary.
Marie Jaja T. Roa- SANTA MARIA WEST CENTRAL SCHOOL- Division of Ilocos Sur
Voluntary muscles are attached to bones and can be controlled
Voluntary muscles are muscles that you have the ability to control, like your arms, legs, face muscles, etc.
Marie Jaja T. Roa- SANTA MARIA WEST CENTRAL SCHOOL- Division of Ilocos Sur
Examples of actions that you can control
Marie Jaja T. Roa- SANTA MARIA WEST CENTRAL SCHOOL- Division of Ilocos Sur
Involuntary muscles are controlled by the nervous system and cannot be controlled consciously...
…like the smooth muscles in the walls of many internal organs such as stomach, esophagus, diaphragm and walls of blood vessels.

Full of BodiesBy Jennifer Prescott
From my fingers to my toes, I’m full of bones.If you count them all as one, they make a
skeleton.From my fingers to my toes, I’m full of bones.
My smallest bone is found inside my ear.The stirrup helps me hear, many sounds both far
and near.My smallest bone is found inside my ear.
Marie Jaja T. Roa- SANTA MARIA WEST CENTRAL SCHOOL- Division of Ilocos Sur
My longest bone is found inside my leg.My femur’s really great,
‘cause it helps me stand up straight.My longest bone is found inside my leg.
My joints help my bones to move around.My hips, elbows, and knee, oh it’s all so plain to
see,That my joints help my bones to move around.
Marie Jaja T. Roa- SANTA MARIA WEST CENTRAL SCHOOL- Division of Ilocos Sur
Where can you find the smallest bone in your body?Where can you find the longest bone in your body?What are the bones mentioned in the poem? Can you feel them?Are your bones hard? Can they be broken?
