Summary

Anatomy is the scientific study of the structures of the human body and how those structures relate to one another. This lesson introduces the range of structures anatomists study, the tools used to observe them, and two common ways of organizing anatomical knowledge.

Human anatomy focuses on the body's physical structures, from large organs that can be seen with the unaided eye to tiny structures that require magnification. The word anatomy comes from a Greek root meaning “to cut apart,” reflecting the historical use of dissection to examine the body.

All flashcards

What is anatomy?
Anatomy is the scientific study of body structures and their physical relationships.
How do dissection and medical imaging differ?
Dissection separates structures for direct examination; imaging visualizes internal structures in living people.
What is homeostasis?
Homeostasis is the maintenance of steady internal conditions in living things.
What does neurophysiology study?
Neurophysiology studies how the brain, spinal cord, and nerves work.
How are form and function related?
A structure's shape and arrangement help explain what it can do.

Quiz questions

  1. What does human physiology investigate?Answer: How body structures work and support life.
  2. Which term describes the maintenance of steady internal conditions in a living organism?Answer: Homeostasis.
  3. Which field examines how signals travel along nerves and how the nervous system supports movement?Answer: Neurophysiology.
  4. Which approach can physiologists use to investigate body functions?Answer: Carefully designed experiments with observation and measurement.
  5. How does the position of the thumb opposite the fingers help the hand?Answer: It supports pinching, grasping, and manipulating objects.
