BIOL 207 Lecture Notes - Lecture 1: Thoracic Cavity, Abdominal Cavity, Serous Membrane
Document Summary
Anatomic position facing forward, standing erects, arms by side, hands facing forward. Orientation/ directional terms superior (cranial) - above inferior (caudal) - below. Lateral towards side and away from midline (radius) Nearest to point of attachment/ reference point. Plane/sections sagittal- parts/entire body divided in left/right sections. Describes superior and inferior sections frontal/coronal separates body into anterior or posterior sections. Medullary region inner regions ( ex. medullary cavity in bone) Both terms relate to double layered serous membrane (serosa) found lining walls/organs of ventral cavity. Visceral - covers organs and inner membrane of the 2. Parietal - lines cavity walls (outer membrane) Pericardial - outer membrane, adheres to surface. Parietal membrane - beneath pericardial membrane serous fluid. Allows both membranes to extend/contract and rub against each other consistency of serous membrane is watery. Pleurae membranes visceral and parietal pleurae visceral - outside. Pleurae cavity - middle, filled with serous fluid.
