Lesson 1 Healing Foot
This process repairs body damage and helps the body return to a function or adapt to a change.
healing
This word means the job or role of a body structure.
function
Doctors use these to see structures inside the foot that they cannot see from the outside.
medical images
These structures carry signals between the body and the brain or spinal cord.
nerves
Name one kind of outside support that helped injured structures stay in place or stay together.
pins, stitches, or a cast
A group of interacting parts that work together for a function is called this.
a system
Name one structure besides bone, muscle, or skin that contributes to how a body part works
a tendon, cartilage, fat, a nerve, or a blood vessel
The brain and nerves work together in this body system.
nervous system
A later image shows a smaller gap between damaged bone pieces. What could this suggest?
The smaller gap could be evidence that the bone is healing.
Describe how skin, muscle, and bone are connected in a moving limb.
Skin attaches to muscle, and muscle attaches to bone.
A body structure made of tissues that work together for a function is called this
an organ
After a foot injury, a student loses feeling in one area. Which type of structure might be damaged?
nerve
The skin looks healed, but the student still has trouble walking. Explain why this is possible.
Different structures heal at different speeds
A student’s muscles are healthy, but a broken bone makes movement difficult. Explain why.
Bones and muscles work together as a system
Nerves and blood vessels are found in all three of these body structures studied in the lesson.
bones, muscles, and skin
Describe how information from a touch on the foot can reach the brain.
Nerves carry signals from the foot through the spinal cord to the brain
Why do different structures heal at different speeds?
Different biological structures heal at different speeds mainly because of blood supply, cell turnover rates, and mechanical stress
Name one structure in the foot and explain its function. Then explain how damage to it could affect walking
Example: Bones support the foot. A broken bone can make it hard to support weight and walk.
Why would a doctor compare a view of the whole foot with a closer image of one injured area?
To examine structures at different scales.
A student can see someone touching the foot but cannot feel the touch. Explain how nerve damage could cause this.
Damaged nerves may keep signals from that part of the foot from reaching the brain normally.
