Corpus callosum—large bundle of nerve fibers that connects the left and right  
hemispheres of the brain together  
Cerebellum—coordinates body movement and maintains the body’s balance and  
equilibrium; located near the spinal cord  
Pituitary gland—small gland located near the base of the brain that controls the  
endocrine glands and influences growth of the human body  
Skull—skeletal structure of the head that protects the brain and other organs  
Nasal bone—side-by-side bones in the middle and upper part of the face that  
vary in size, depending on the individual  
Nasal cavity—inside area of the nose lined with a mucus membrane that keeps  
the nose moist  
Tongue—muscular organ on the bottom of the mouth that aids in chewing,  
swallowing, and speaking  
Spinal cordpart of the nervous system that extends from the base of the brain

speaking, and more  
B. Corpus callosum—large bundle of nerve fibers that connects the left and  
right hemispheres of the brain together  
C. Eye socket—the cavity of the skull in which the eye is located  
D. Cerebellum—coordinates body movement and maintains the body’s balance

E. Sinus cavity—air-filled spaces within the skull and face that filter and  
moisten ingested air  
F. Optic nerve—sends visual information from the retina (part of the eye) to  
the brain  
G. Jawbone—bone of the lower jaw that holds the lower teeth in place  
H. Teeth—hard, bonelike structures in the upper and lower jaws used for  
chewing and biting  
I. Carotid artery—main artery that supplies the head and neck with  
oxygenated blood

A. Eardrum—thin piece of skin separating the outer and middle ear that  
vibrates and amplifies sound waves before entering the middle ear  
B. Cochlea—spiral-shaped tube of the inner ear that contains nerve endings  
that are needed for hearing  
C. Middle ear—central part of the ear that consists of the eardrum and a cavity  
containing three small bones  
D. Eustachian tube—tube that connects the middle ear to the pharynx and  
equalizes air pressure on either side of the eardrum

Interesting Facts  
• The human skull contains 22 bones.  
Your brain is more active and thinks more at night than during the day.  
• The brain stops growing at age 15, but learning never stops.  
• The spinal cord and nerves—known as the nervous system—let messages flow  
back and forth between the brain and the body.  
• We actually “see” with our brains; the eye is basically a camera.  
• The strongest muscle in the body is the tongue.  
• The average person has 32 teeth.  
• Our eyes are always the same size from birth, but our nose and ears never  
stop growing.  
Your thumb is the same length as your nose.

Suggested Activities  
• Use for classroom demonstration as well as individual student exploration.  
• Allow students to hold the model, take it apart, and put it back together. Ask  
students to make observations about the model and have them discuss what  
they already know about the organs and structures of the human head.  
• Use the section of the model featuring the labeling letters to quiz students on  
which part of the head each letter represents. Make photocopies of the  
diagram on page 4 to use as a quiz or review. (Perform this activity using the  
“ear piece” of the head model and the diagram on page 6.)  
• Discuss the five senses and how they relate to the model. Ask students to name  
one of the senses and then locate the organ(s) that works to support that sense.
