Anatomy is the study of structure in the human body
Location of bones
Composition of body
Composition
The body is composed of:

The head is superior to the feet
Inferior: bottom
The feet are inferior to the head
Anterior: front
The eyes are anterior to the back of the head
Posterior: back
The eyes are posterior to the nose
Medial: middle
The heart is medial to the left arm

The left arm is lateral to the heart.
Systems of the body Integumentary: skin, hair, nails
Skeletal: bones supporting body and organs
Nervous: collects and process info through nerves and the brain.
