What is anatomy?

• Study of body structures and relationships among
  them

How do we see these structures?
Dissection
Radiography
Contrast Imaging (microscopy)
MRI

Anatomy and physiology structure and function

• How do you do anatomy?
• Inspection-looking
• Palpation-touching
• Auscultation-listening
• Percussion- tapping and listening
• Gross anatomy (surface, systemic, regional)
• Developmental
• Comparative

• Supports and separates organs
• Principal body cavities are dorsal and ventral
• These are subdivided into smaller cavities

Summary

• Anatomy is the study of body structure and
  organization
• Body organization can be studied at the
  molecular, cellular, tissue, organ, organ system
  and organismal level
• The language of anatomy helps describe the
  specific position and location of body structures
• The body organization can be studied with
  invasive and noninvasive procedures.
