Anatomy Terminology and Body Planes

Vocabulary terms covering anatomical positions, body planes, directional terminology, and mnemonic acronyms as presented in the lecture notes.

Anatomical Position

The standard reference point used to describe all positions and movements, characterized by standing upright, face and feet forward, and arms at the sides with palms facing forward.

Left and Right (Medical Reference)

Directional terms that always refer to the patient’s left and right, regardless of the observer's perspective.

Body Planes

Imaginary flat surfaces that divide the body into portions to allow for detailed views, such as MRI or CT scans.

Sagittal Plane

A vertical plane that divides the body into right and left portions.

Midsagittal (Median) Plane

A plane that passes exactly through the midline, creating equal right and left halves.

Parasagittal Plane

Any sagittal cut that is offset from the midline, resulting in unequal right and left portions.

Frontal (Coronal) Plane

A plane that divides the body into front (anterior) and back (posterior) portions.

Transverse (Axial) Plane

A horizontal cut dividing the body into top (superior) and bottom (inferior) portions.

Oblique Plane

An anatomical slice that passes through the body or an organ at an angle (slant) rather than strictly vertical or horizontal.

SOFT

An acronym used to remember the four major planes: Sagittal, Oblique, Frontal, and Transverse.

Superior (Cranial)

Toward the head or upper part of a structure.

Inferior (Caudal)

Away from the head or toward the lower part of a structure.

Anterior (Ventral)

Toward the front of the body.

Posterior (Dorsal)

Toward the back of the body.

Medial

Toward the midline of the body.

Lateral

Away from the midline; toward the outer sides.

Proximal

Used for limbs to describe a position closer to the point of attachment or the trunk of the body.

Distal

Used for limbs to describe a position farther from the point of attachment or the trunk of the body.

Superficial

Toward or at the body surface.

Deep

Away from the body surface; more internal.

Supine

A body position where the individual is lying face up.

Prone

A body position where the individual is lying face down.

Lateral Recumbent

A body position where the individual is lying on the side (left or right).
