What is included in the posterior dorsal body cavity?
Includes a cranial cavity containing the brain and a spinal cavity containing the spinal cord.
What is included in the anterior ventral body cavity?
Includes the thoracic cavity which is subdivided into a mediastinum containing primarily the heart, esophagus., lungs, and trachea with the longs located on either side of the mediastinum. Also included is the abdominal pelvic cavity composed of an abdominal cavity and pelvic cavity.
What is the main function of the diaphragm?
Seperates thoracic and abdominal cavities.
What are the smaller cavities within the head?
Oral Cavity, Nasal Cavity with connected sinuses, Orbital Cavity, Middle Ear Cavity.
What is stored in the orbital cavity?
Houses eye and associated structures.
What is stored in the middle ear cavity also known as tympanic cavity?
air filled and contains auditory ossicles.
What are serous membranes?
Composed of mesodermally derived epithelium called mesothelium (supported by connective tissue)
Line cavities that do not open to the outside and cover organs located within those cavities
HAVE TWO LAYERS.
What are the two layers of serous membranes?
Visceral and Parietal.
Define visceral:
inner layer that covers internal organs
Define Parietal
Outer layer that lines body cavity wall`
What is parietal pleura?
It lines the outer cavity containing the lung.
What is visceral pleura?
Inner layer of plueral cavity, covers the lung.
What is the plueral cavity?
Space between visceral pluera and parietal pluera.
What is the parietal pericardium?
Outer layer of the pericardial cavity, attaches to the sternum and diaphragm.
What is the visceral pericardium?
Inner layer of the pericardial cavity. It covers the heart.
What is the pericardial cavity?
The space between the visceral pericardium and the parietal pericardium.
What is the visceral peritoneum?
The inner layer of the abdominal cavity, it covers the organs.
What is the parietal peritoneum?
The outer layer of the abdominal cavity, it lines the cavity wall.
