Study Notes
Human Anatomy Overview
- Human anatomy studies the body's structure, divided into regions: head, neck, trunk, and limbs.
- General anatomy introduces a vocabulary for anatomical positions and structure types.
Anatomical Position
- The anatomical position features an upright stance, arms at sides, palms forward, and eyes straight ahead.
- Dissection terms are always referenced as if the body is in this position.
Terms of Position
- Superior (Cephalic): Closer to the head.
- Inferior: Closer to the feet; can use caudal in the trunk to denote a downward position.
- Anterior: Nearer to the front; posterior means nearer to the back.
- Ventral and Dorsal: Synonyms for anterior and posterior in the trunk; dorsal can indicate posterior in the hand, while ventral is not usually used for the feet.
Planes and Directions
- Median Plane: Imaginary line dividing the body into equal right and left halves.
- Anterior and Posterior Median Lines: Where median plane intersects the body surfaces.
- Medial: Closer to median plane; lateral: further from it.
- Ulnar and Radial: Terms for sides of the forearm; fibular and tibial for the leg.
Surface Terms
- Outer and Inner: Used to describe proximity to the surface, synonymous with external and internal.
- Superficial: Closer to the skin; deep: further away.
- External and Internal: Describe surfaces of hollow organs.
Types of Planes
- Sagittal Plane: Parallel to median plane, dividing body into right and left sections.
- Coronal Plane: Vertical plane at a right angle to median plane.
- Transverse Plane: Horizontal plane cutting across the body perpendicular to median and coronal planes.
- Oblique Planes: Any planes that are not parallel or perpendicular to the median or coronal planes.
Relation of Structures
- Proximal: Closer to the root or origin; distal: further from it.
- Example: The elbow is proximal to the wrist but distal to the shoulder.
