Study Notes

Body Organization

  • Body organization progresses through several levels: Chemical, Cellular, Tissue, Organ, Organ system, and Organismal.

Life Functions

  • Essential life functions include:
    • Maintaining boundaries
    • Movement
    • Responsiveness
    • Digestion
    • Metabolism
    • Excretion
    • Reproduction
    • Growth

Survival Needs

  • Vital survival needs encompass:
    • Nutrients
    • Oxygen
    • Water
    • Appropriate temperature
    • Appropriate pressure

Oxygen's Role

  • Oxygen is crucial for the release of energy from food via cellular respiration.

Anatomy vs. Physiology

  • Anatomy focuses on the structure and shape of body parts.
  • Physiology examines how these parts function and work together.

Directional Terms

  • Inferior (caudal): refers to a position below.
  • Superior (cranial): denotes a position above.
  • Anterior (ventral): indicates being at the front.
  • Posterior (dorsal): suggests being at the back.
  • Medial: means toward the midline.
  • Lateral: means toward the side.
  • Intermediate: lies between two structures.
  • Proximal: indicates closeness to a reference point.
  • Distal: refers to being far from a reference point.
  • Superficial: describes being on the surface.
  • Deep: indicates a position toward the center.

Planes of the Body

  • Frontal (Coronal) plane: divides the body into anterior and posterior.
  • Sagittal plane: creates a right and left division; can be uneven.
  • Midsagittal plane: produces an equal right and left division.
  • Transverse plane: separates the body into superior and inferior parts.

Anatomical Relations

  • The lungs are lateral to the heart, while the heart is intermediate to the lungs.

Specific Regions

  • The umbilical region contains the navel.

Cavity Separation

  • The transverse plane can separate the thoracic cavity from the abdominopelvic cavity.
