Bones enable you to do this
What is move?
One of the three things that muscles permit you to do.
What are movement of the body, maintain posture and circulates blood throughout the body.
The two main parts of the nervous system
What are central nervous system and the peripheral nervous system?
Light enters the eye though the ___________
What is the cornea?
Sound waves move down ear canal causing the eardrum to vibrate. Those vibrations then move though these three small bones.
What are the hammer, anvil, and stirrup?

What is water?
The three types of muscles in human body
What are skeletal, cardiac, and smooth?
The main parts of the central nervous system.
What are the brain and the spinal cord?
The amount of light that passes through the pupil is regulated by ______, or the colored part of your eye.
What is the iris?
The vibrations then move into the cochlea causing these things to move. It is there movement that create neural signals. Those located at one end of the cochlea transfer low pitch sound information and those at the opposite end transfer high pitch sound information.
What are hair cells?
Bones protect these
What are internal organs?
The function of skeletal muscles
What is
• Directly attached to the skeleton by tendons.
• Aid in movement.
• Are voluntarily activated.
The main parts of the peripheral nervous system
What are the cranial, spinal, and peripheral nervous?
This is the transparent structure inside the eye which focuses light rays onto the retina.
What is the lens?
This moves signals to the brain where they are then translated into recognizable and meaningful sounds. It is the brain that “hears”.
What is the auditory nerve?
These link bones together and allow for movement. You can find them in your knee and elbow for example.
What are joints?
The function of cardiac muscles
What are
• Contract involuntarily. Regulated by autonomic part of nervous system.
• Found in walls of hollow structures, including veins, arteries, and intestines.
• Maintain flow of fluid and food along hollow structures.
Cells that carry information through your nervous system.
What are neurons?
This is the light-sensitive nerve layer that lines the back of the eye, where the image appears inverted.
What is the retina?

What is a cochlear implant?
The total number of bones in an adult human body.
What is 206
The function of cardiac muscles.
What is
• Found only in heart and at cardiac ends of main blood vessels.
Allow the heart to function correctly
How the nervous system works
Neurons in the peripheral nerves send messages to the spinal cord that go to the brain. The brain makes a decision on how to respond and sends that message back down to that part of the body telling it how to act.
This carries signals of light, dark, and colors to the area of the brain (the visual cortex), which assembles the signals into images (our vision).
What is the optic nerve?
How does the ability to see and hear point us to a creator God?
