Study Notes
Directional Terms
- Used to describe the location of body structures in relation to each other
- Essential for accurate communication in anatomy and medicine
Types of Directional Terms:
- Anterior (ventral): towards the front of the body
- Posterior (dorsal): towards the back of the body
- Superior: towards the head or upper part of the body
- Inferior: towards the feet or lower part of the body
- Medial: towards the midline of the body
- Lateral: away from the midline of the body
- Proximal: towards the point of attachment or origin
- Distal: away from the point of attachment or origin
- Cephalad: towards the head
- Caudad: towards the tail or feet
Body Planes
- Imaginary planes that divide the body into sections
- Used to describe the location and orientation of body structures
Types of Body Planes:
- Sagittal plane: divides the body into left and right halves
- Frontal (coronal) plane: divides the body into front and back halves
- Transverse (horizontal) plane: divides the body into top and bottom halves
- Oblique plane: at an angle to the sagittal, frontal, and transverse planes
Additional Concepts
- Medial plane: passes through the midline of the body, dividing it into left and right halves
- ** Parasagittal plane**: parallel to the sagittal plane, but not passing through the midline
- Longitudinal section: a cut along the long axis of the body
- Cross-section: a cut perpendicular to the long axis of the body
