Sectional View
What kind of sectional view (plane) could you call the diagram above?
Dorsal Body Cavity
1. Cranial Cavity Contains the brain and CSF.Protects this delicate tissue.
2. Spinal Cavity Contains the spinal cord and CSF.Protects this delicate tissue.
Ventral Body Cavity1. Thoracic Cavity
Contains: a) Plural cavities (lungs inside).b) Mediastinum
i) Pericardial cavity (heart).
2. Abdominopelvic Cavity Contains: stomach, intestines, gallbladder,liver, spleen, bladder, reproductive organs.
B. Pericardium - lines the pericardial cavity.
MediastinumContains: Heart, thymus, trachea, esophagus, vessels (aorta), nerves.
A. Pleura - membrane lining the pleural cavities.
Serous Membranes - line ventral body cavities, has 2 portions:
VisceralParietal
Peritoneum - lines the peritoneal cavity (this is inside the abdominal cavity).
The Abdominopelvic cavity contains the Peritoneal cavity
Mesenteries - support and stabilize the digestive organs in abdominal cavity.
