Quiz # 1 Body Cavities and Associated Structures Flashcards
Posterior Cavity
(Dorsal Body Cavity) Made up of the Cranial Cavity and the Vertebral Canal
Cranial Cavity
Houses the Brain (Provides Cushion and Support)
Vertebral Canal
(Spinal Cavity) Cushions and supports the spine made up of bones from the vertebral column
Anterior Cavity
(Ventral Body Cavity)
Diaphram
(Anterior Body Cavity Component) Separates the thoracic cavity (Superior) from the abdominopelvic cavity (inferior)
Thoracic Cavity
“Chest Cavity” formed by the ribs, muscles of the chest, the sternum (breast bone), and the thoracic portion of the vertebral column
Visceral Pleura
Clings to the surface of the lungs
Parietal Pleura
lines the chest wall and covers the superior portion of the diaphragm
Mediastinum
Central portion of the thoracic cavity, between the two medial walls of the two pleurae and extends from the first rib to the diaphragm and sternum to the vertebral column.
Visceral Pericardium
Lines the heart (On the heart Surface)
Parietal Pericardium
Outer lining that lines the fibrous pericardium that lines the heart
Pericardial Cavity
Between the visceral and parietal cardium
Abdominopelvic cavity
Extends from the diaphragm to the groin, encircled by abdominal muscle wall and bones and muscles of the pelvis, two portions abdominal cavity and the inferior pelvic cavity
Visceral peritoneum
Lines the abdominal viscera
Parietal Peritoneum
Lines the abdominal wall and the inferior surface of the diaphragm
