Anatomical Positions & Directions Anatomists, those in the medical community and others use directional terms to describe body positions and directions
Anatomical Positions & Directions These directional and positional terms are applied using the standard anatomical position
Anatomical Positions & Directions Planes • frontal • transverse • median (sagittal) Frontal Median Transverse
Anatomical Positions & Directions Anatomical directions: • anterior (ventral) • posterior (dorsal) Frontal
Anatomical Positions & Directions Anatomical directions: • superior (cephalic) • inferior (caudal) Transverse
Anatomical Positions & Directions Anatomical directions: • lateral • medial • proximal • distal Median
Anatomical Positions & Directions External regions: • RUQ • LUQ • RLQ • LLQ
Anatomical Positions & Directions • Internal regions: • hypochondriac • epigastric • lateral • umbilical • • hypogastric • • inguinal
Anatomical Positions & Directions • Body cavities: • dorsal • - cranial • - vertebral • ventral • - thoracic • - abdominal • - pelvic
Anatomical Positions & Directions Thoracic cavity: • pleural • pericardial • mediastinum Diaphragm
Body Membranes The membranes that line the body cavities and cover the internal organs are named for the organs or regions that they cover
Body Membranes Membranes that line the body cavities are called parietal membranes Membranes that cover internal organs are called visceral membranes
