Terminologia Anatomica 2nd Edition (underline)

list of 10,000 proper anatomic names for body parts in latin and english

Anatomic position

The universal reference frame used when comparing one body part to another

sagittal plane

any vertically oriented plane that divides the body into right and left portions

Median plane

a sagittal plane that courses through the entire anterior (front) and posterior (back) midlines of the body. it is parallel to other sagittal planes. The median plane is sometimes called the midsagittal plane.

Coronal plane

any vertically oriented plane perpendicular to the median plane which divides the body into anterior (front) and posterior (back) portions. Frontal plane is a former name for this plane

Tranverse Plane

any horizontally oriented plane that divides the head, neck, trunk, or limbs into superior (upper) and inferior (lower) portions. Sometimes this plane is referred to as a horizontal plane.

Directional Terms

Terms used to explain where one body structure is in relation to another

Medial

toward or relatively closer to the median plane

Lateral

away from or relatively farther from the median plane

Anterior

toward or relatively closer to the front side of the body

Posterior

toward or relatively closer to the backside of the body

Superior

toward or relatively closer to the top of the head.

Inferior

away from or relatively farther from the top of the head.

Proximal

toward or relatively closer to a reference point. This term is usually applied to the limbs with the reference point at the attachment of the limb to the trunk. When used on a limb, it has the same general meaning as superior except on the foot where it is equivalent to posterior due to the perpendicular angle at the ankle. When it is applied to the alimentary canal (digestive tube), the reference point is usually the mouth and when it is applied to cardiovascular structures, the reference is usually the heart. Venous blood flows this way in the limbs as it returns to the trunk from the feet and hands.

Distal

Away from or farther from a reference point. Applied to limbs where it means same as inferior (except for feet)

Middle

a position between superior/inferior, anterior/posterior, proximal/distal, or superficial/deep

Intermediate

A side-to-side position between medial and lateral structures

Longitudinal

parallel to the long axis of an elongated structure (lengthwise)

Transverse

perpendicular to the long axis of an elongated structure (across)
