Lower torso area: Contains urinary bladder, reproductive organs, and rectum

Deep

On the inside; below other tissues; toward the core of the body

Superficial

On the outside; toward the outside edge

Vertebral Cavity (Spinal Cavity)

Spine area: runs within the bony vertebral column, encloses the delicate spinal cord

Anatomical Position

The basic reference position used for all directional terms in Anatomy. Feet forward, face forward, arms at sides palms rotated forward.

Transverse section

Top/Bottom

Frontal/Coronal

Vertical plane that cuts the body in two parts creating a FRONT and a BACK half. Means "*crown*."
