Anatomy Basics
Anatomic PositionFrame of Referenceanatomic positionstanding, feet togetherarms slightly away from bodypalms out
Anatomic PositionSpecific names are more
precise
superior/inferiorabove or below
same as caudad/cepalad
medial/lateraltoward or away from midline
proximal/distalcloser or further away
superior
inferior
medialmedial lateral
proximal
distal
Anatomic PositionSpecific names are more
precise
anterior/posteriorfront and back
same as ventral/dorsal
superficial/deepclose to body surface/deep to body surface
skin is superficial to muscle
posterioranterior
Anatomic PositionPlanesfrontal plane
divides the body into anterior and posterior parts
transverse planecross section dividing the body into superior and inferior parts
sagittal planedivides the body into right and left parts“midsagittal” plane
runs exactly through the middle

Body Cavities“Hollow” areas that
contain and protect organs
Dorsal Cavitycontain brain and spinal cord
Ventral Cavitythoracic cavityabdominopelvic cavity
Body CavitiesSerous Membranes
body cavities covered with a thin, double layered membrane
wraps around cavity surface and around organs
cavity serosa=parietal layerorgan serosa=visceral layer
secretes a thin fluid that reduces friction of moving body parts
Body CavitiesSerous Membranes
have different names depending on cavity
Thoracic Cavity (3 divisions)Pleural Cavity
between lungs and chest walllined with pleura
Pericardial Cavitysurrounds heartlined with pericardium
Mediastinumcavity that contains heart, trachea, esophagus, aorta, etclined with parts of pleura and pericardium
Body CavitiesSerous Membranes
have different names depending on cavity
Abdominal Cavityarea between the abdominal organs and the abdominal walllined with peritoneum
Abdominal QuadrantsAbdomen divided into 4
equal areas
Right Upper Quadrant (RUQ)
gallbladder/liverLeft Upper Quadrant (LUQ)
stomach and spleenRight Lower Quadrant (RLQ)
appendixLeft Lower Quadrant (LLQ)
diverticulitis
Abdominal RegionsAbdomen divided into 9
equal areasMedically the midline regions are most significant
Epigastric Regionstomach
Umbilical Regionarea of referred pain
Hypogastric Regionbladder infection
