Study Notes
Anatomical Position
- When describing a proximo-distal axis, the position assumed is with the body upright, feet pointing forward, and arms at the sides.
- In the standard anatomical position, the feet are placed parallel to each other, pointing forward, and in a neutral position.
Arms and Hands
- In the standard anatomical position, the arms are positioned at the sides of the body, with the palms facing forward.
- The hands are placed in a supine position, with the thumbs pointing forward and the palms facing forward.
Penis
- In the standard anatomical position, the penis is positioned upright, with the dorsal surface facing forward.
- The dorsal surface of the penis is actually called the dorsum of the penis when flaccid.
Purpose of Standard Anatomical Position
- The main purpose of using standard anatomical positions is to provide a common reference point for descriptive purposes.
Limbs and Body
- In the standard anatomical position, the limbs are placed in a position reminiscent of the supine position.
- The arms are positioned in relation to the body with the palms facing forward.
Skull and Frankfurt Plane
- The Frankfurt plane is considered to be the anatomical position of the human skull.
- The Frankfurt plane was established in 1884.
- The Frankfurt plane is defined by the points of the inferior margin of the left orbit and the superior margin of each ear canal.
- The Frankfurt plane is also known as the auriculo-orbital plane.
- The Frankfurt plane is considered to be the anatomical position of the human skull in humans and primates.
- In dogs, the anatomical position is different from the Frankfurt plane.
Angles and Base Lines
- The Frankfurt-Mandibular plane Angle (FMA) is a measure used in orthodontics.
- Reid's base line is another name for the Frankfurt plane.
Fields of Use
- The standard anatomical position is used as a reference point in fields such as anatomy, medicine, and orthodontics.
- The Frankfurt plane is used as a reference point in fields such as orthodontics and anatomy.
