Body Cavities Flashcards
Cranial Abdominal Contains:
• Xiphoid or epigastric region
• Hypochondriac region (L&R)
Middle abdominal Contains:
• Umbilical region
• Lateral regions (L&R)
Caudal abdominal Contains:
• Pubic region
• Inguinal region (L&R)
TWO CAVITIES OF THE BODY:
• Dorsal Cavity
• Ventral Cavity
What cavity of the body contains cranial cavity and spinal cavity
Dorsal Cavity
What cavity of the body contains visceral organs
Ventral Cavity
What are the compartments of the body?
Body cavities
Body cavities are 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
Thoracic cavity bounded laterally by?
Ribs
Thoracic cavity bounded ventrally by?
Sternum
Thoracic cavity bounded dorsally by?
Vertebral column
Thoracic cavity bounded cranially by?
Thoracic inlet
Thoracic cavity bounded caudally by?
Diaphragm
• The space within the trunk between the diaphragm and the pelvic cavity
ABDOMINAL CAVITY
Abdominal cavity bounded cranially by?
Diaphragm
Abdominal cavity bounded laterally and ventrally by?
Muscles of the body wall
Abdominal cavity bounded dorsally by?
Lumbar vertebrae
Abdominal cavity bounded caudally by?
Pelvic inlet
• Or the pelvis; it contains the rectum, the anal canal and the pelvic parts of the reproductive and urinary viscera
PELVIC CAVITY
PELVIC CAVITY has two parts:
- peritoneal part
- retroperitoneal part
the cranial portion lined by pouches of the abdominal peritoneum
Peritoneal part
the caudal portion not lined by abdominal peritoneum
Retroperitoneal part
Pelvic cavity bounded cranially by?
Abdominal cavity
Pelvic cavity bounded dorsally by?
Sacrum
Pelvic cavity bounded laterally and ventrally by?
Pelvis
Pelvic cavity bounded caudally by?
Perineum
The thoracic and abdominal cavities are separated by the?
diaphragm
The abdominal and pelvic cavities are continuous; their junction is referred to as?
pelvic inlet
are all derivatives of the lining of the celomic cavity of the embryo
serous membranes
forms a continuous sac that is usually empty except for a small amount of serous (watery) fluid.
serous membrane
What are not found inside any of the serous sacs, although
most viscera are covered by at least one layer of a serous
membrane
viscera
No viscera are found inside any of the serous sacs, although most viscera are covered by at least one layer of a?
serous membrane
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
What covers the organs?
Visceral pleura
The pleura found in the heart is the?
pericardial pleura or pericardium
