Anatomical Position and Body Planes
Introduction
- Purpose: Discuss anatomical position and body planes, and provide memory tricks.
- Next Video: Will cover anatomical directional terms.
Anatomical Position
- Definition: Standard body orientation for anatomical reference.
- Position Details:
- Standing upright
- Head and eyes forward
- Upper limbs at sides, palms forward, thumbs out
- Feet together, flat on ground, facing forward
- Right and Left: Refer to the patient's perspective, not the observer's.
Body Planes and Sections
- Body Planes: Imaginary lines dividing the body.
- Vertical or Horizontal: Divide body into sections.
- Body Sections: Result from cuts along planes.
Major Body Planes
Sagittal Plane
- Definition: Vertical plane dividing body into right and left.
- Mid-sagittal Plane: Divides body into equal right and left portions.
- Parasagittal Plane: Divides body into unequal right and left portions.
- Memory Aid: "Sagittal" and "side view" both start with "S".
- Examples:
- Sagittal suture in skull.
Coronal Plane (Frontal Plane)
- Definition: Vertical plane dividing body into front and back.
- Memory Aid: "Frontal plane" gives front view.
- Examples:
Transverse Plane (Axial or Horizontal Plane)
- Definition: Horizontal plane dividing body into top and bottom.
- Memory Aid: "Transverse" and "T" for upper body.
- Examples:
- X-axis runs horizontally.
Minor Body Planes
Longitudinal Plane
- Definition: Any plane perpendicular to transverse plane.
- Includes: Sagittal and coronal planes.
- Memory Aid: Longitudinal lines on a globe.
Oblique Plane
- Definition: Any plane not vertical or horizontal.
- Memory Aid: "Oblique" and "odd" both start with "O".
By understanding these concepts, you can have a clear framework when discussing and studying human anatomy. Watch future videos for more related topics.
