BODY CAVITIES Flashcards
cranial cavity and spinal cavity
Dorsal Cavity
visceral organs
Ventral Cavity
are the compartments of the body
Body cavities
Body cavities is divided into three:
• Thoracic cavity
• Abdominal cavity
• Pelvic cavity
• The space within the thorax containing the thoracic organs, the
pleura and pleural cavities, the pericardium and pericardial cavity
THORACIC CAVITY
is formed by the first pair of rib and the vertebra and sternebra to which they connect
thoracic inlet (cranial thoracic opening)
• The space within the trunk between the diaphragm and the
pelvic cavity
ABDOMINAL CAVITY
• it contains the rectum, the anal canal and the pelvic parts of
the reproductive and urinary viscera
PELVIC CAVITY
the cranial portion lined by pouches of the abdominal peritoneum
Peritoneal part
the caudal portion not lined by abdominal peritoneum
Retroperitoneal part
are all derivatives of the lining of the celomic cavity of the embryo.
serous membranes
surrounds the organs in the thoracic cavity
Pleura
lines the visceral organs in the abdominal and pelvic cavity
Peritoneum
adheres to the walls of the ventral cavity
Parietal serous membranes
adhere to the organs inside the ventral cavity
Visceral serous membranes
covers the organs
Visceral pleura
covers the body wall
Parietal pleura
small cup-shaped bubbles of pleura at the cranial lung that protrude through the thoracic inlet
Pleural cupulae
triangular, transparent double fold of pleura between the caudal lobe of the lung and caudal end of hilus
Pulmonary ligament
