Study Notes

Anatomy and Physiology

  • Anatomy: The study of body structures and their relationships.
  • Physiology: The study of how body parts work together to function.
  • Complementarity of Structure and Function: The form of a biological component (e.g., cell, organ, organism) dictates its function.
  • Homeostasis: Maintaining stable internal conditions despite external changes.

Hierarchy of Organization

  • Chemical Level: Atoms form molecules.
  • Cellular Level: Molecules combine to form cells.
  • Tissue Level: Similar cells form tissues.
  • Organ Level: Different tissues combine to form organs.
  • Organ System Level: Organs work together in organ systems.
  • Organism Level: All organ systems work together in the organism.

Directional Terms

  • Sagittal Plane (Median Plane): Divides the body vertically into left and right halves.
  • Parasagittal Plane: Parallel to the sagittal plane but off to one side.
  • Coronal Plane (Frontal Plane): Divides the body vertically into front and back sections.
  • Transverse Plane (Horizontal Plane): Divides the body horizontally into top and bottom sections.

Body Parts

  • Axial Parts: Head, neck, and trunk (midline structures).
  • Appendicular Parts: Arms, legs, and appendages attached to the axial skeleton.
