Anterior and Posterior

Front and Back sections

Superior and Inferior

Top and Bottom sections

The study of tissues is called

Divides the body into anterior and posterior sections

gross anatomy

Includes parts of the body that can be seen with the naked eye. Also called Macroscopic Anatomy.

Physiology can be broken into 2 groups

Ventral

On the belly side

Right and Left

Patients Right and Left Sections

Morphology

Biology

Caudad (caudal)

Toward the soles of the feet

Cephalad (cranial)
