Study Notes
Planes of the Body
- Sagittal Plane: Divides the body into left and right sections; portions do not need to be equal.
- Midsagittal Plane: A specific sagittal plane that separates the body into equal left and right halves.
- Frontal Plane: Divides the body into anterior (front) and posterior (back) parts.
- Transverse Plane: Separates the body into superior (top) and inferior (bottom) portions.
Directional Terms
- Superior: Refers to a position that is higher or above another part.
- Inferior: Indicates a position that is lower or below another part.
- Anterior: Denotes a position toward the front of the body.
- Posterior: Refers to a position toward the back of the body.
- Cephalic: Indicates a direction toward the head; varies for different species (top in humans, front in quadrupeds).
- Caudal: Points toward the tail or lower end of the body; also varies by species.
- Ventral: Refers to the stomach area; front in humans, ground level in quadrupeds.
- Dorsal: Indicates the back or spine, top in quadrupeds.
Positioning Relative to the Midline
- Medial: Closer to the body's midline.
- Lateral: Further away from the body's midline.
- Contralateral: Refers to the opposite side of the midline.
- Ipsilateral: Pertains to the same side of the midline.
Limb and Attachment Reference
- Proximal: Closer to the point of origin or where an attachment occurs.
- Distal: Further away from the point of origin or attachment.
Depth Orientation
- Superficial: Toward or on the surface of the body.
- Deep: Away from the surface, toward the core of the body.
