Study Notes
Anatomical Position
- The body is in a standing position with head, eyes, and toes directed forward.
- Upper limbs are positioned by the sides with palms facing forward.
- Lower limbs are kept close together, feet parallel, and toes directed forward.
Anatomical Terms
- Anterior (frontal): Refers to the front of the body.
- Posterior (dorsal): Refers to the back of the body.
- Superior: Indicates a position towards the head.
- Inferior: Indicates a position towards the feet.
Proximity Terms
- Proximal (nearest): Indicates a point closer to the root; for example, the elbow is proximal to the wrist.
- Distal (remote): Indicates a point farther from the root; for example, the elbow is distal to the shoulder joint.
Plane and Position Terms
- Median: Describes a point on the midsagittal or median plane.
- Medial: Refers to a position closer to the midsagittal plane than another point.
- Lateral: Indicates a position farther from the midsagittal plane; for instance, the outer side of the elbow is lateral to its inner side.
Studying Anatomy
- Regional anatomy involves organizing the body into specific parts: head, neck, trunk (further divided into thorax, abdomen, pelvis/perineum, and back), and paired upper and lower limbs.
