Below is a link I made on youtube describing the directional terms of the body parts. Not amazing graphics it is my first video but it explains the terms a bit more visually. The actual terms are defined below!
Body Erect- feet slightly apart, palms facing forward, thumbs pointing away from body.
Superior- Towards the head or upper part of the body
Inferior- Away from the head or toward the lower end of the body
Anterior- Toward the front of the body
Posterior- Toward the back of the body
Medial- toward the midline of the body
Lateral- Away from the midline of the body
Intermediate- Between a medial and lateral structure
Proximal- Closer to the origin of the body
Distal- Father from the origin of the body
Superficial- Toward the surface of the body. The skin is more superficial than the heart.
Deep- away from the body surface, more interior
Sagittal- divides the body into right and left parts
Midsagittal- Sagittal plane that lies on the midline
Transverse or horizontal- divides the body to interior and superior parts
Oblique Sections- Cuts made diagnolly
