Body Cavities And Membranes

Front 1

Abdominal Cavity

Back 1

Contains the stomach, intestines spleen, liver, and other organs.

Front 2

Abdominopelvic Cavity

Back 2

The abdominopelvic cavity is a body cavity that consists of the and the pelvic cavity. It contains the stomach, liver, spleen, gallbladder, kidneys, and most of the small and large intestines. It also contains urinary bladder and internal reproductive organs.

Front 3

Cranial Cavity

Back 3

The cranial cavity, or intracranial space, is the space formed inside the skull. The brain occupies the cranial cavity, which is lined by the meninges and which contains cerebrospinal fluid to cushion blows.

Front 4

Dorsal Body Cavity

Back 4

The space within the cranium (skull) and the spinal canal, which is surrounded by the vertebrae.

Front 5

Mediastinum Cavity

Back 5

The mediastinum lies between the right and left pleura in and near the median sagittal plane of the chest. It extends from the sternum in front to the vertebral column behind, and contains all the thoracic viscera except the lungs.

Front 6

Spinal/vertebral canal or spinal/vertebral cavity

Back 6

The space in vertebrae through which the spinal cord passes.

Front 7

Ventral Body Cavity

Back 7

The chamber of the human body made up of the thoracic cavity, and the abdominopelvic cavity. The abdominopelvic cavity is further separated into the abdominal cavity and pelvic cavity, but there is no physical barrier between the two. The abdominal cavity contains digestive organs, the pelvic cavity contains the urinary bladder, internal reproductive organs, and rectum.

Front 8

Thoracic cavity/chest cavity

Back 8

The chamber of the human body that is protected by the thoracic wall and includes structures the cardiovascular including heart and great vessels, the respiratory system including trachea, bronchi and lungs, and the digestive system, including the esophagus.

Front 9

Pleural cavity

Back 9

the potential space between the two pleura (visceral and parietal) of the lungs.

Front 10

Pericardial cavity

Back 10

The potential space between the parietal pericardium and visceral layer. It contains a supply of serous fluid.

Front 11

Abdominal cavity

Back 11

The body cavity of the human body that holds the bulk of the viscera.

Front 12

Pelvic cavity

Back 12

The body cavity that is bounded by the bones of the pelvis. It contains the reproductive organs, the urinary bladder, the pelvic colon, and the rectum.

Front 13

Peritoneal cavity

Back 13

The potential space between the parietal peritoneum and visceral peritoneum.

Front 14

Oral Cavity or mouth

Back 14

The cranial cavity that is the first portion of the alimentary canal that receives food.

Front 15

Nasal cavity

Back 15

The cavity that conditions the air to be received by the other areas of the respiratory tract. It is mainly made up by the maxilla, and also includes portions of the perpendicular plate of the palatine bone, the medial pterygoid plate, the labyrinth of the ethmoid and the inferior concha.

Front 16

Orbital Cavity

Back 16

The cavity or socket of the skull in which the eye and its appendages are situated. It is made up of the superior margin of the frontal bone, the inferior margin of the maxilla and zygomatic.

Front 17

Middle ear cavity

Back 17

An air-filled cavity in the cranium behind the ear drum (tympanic membrane), includes the three ear bones or ossicles: the malleus (or hammer), incus (or anvil), and stapes. (or stirrup). The opening of the Eustachian tube is also within the middle ear.

Front 18

Parietal pleura

Back 18

The portion of the pleural serous membrane that lines the inner surface of the chest wall, covers the diaphragm, and is reflected over the structures occupying the middle of the thorax.

Front 19

Visceral/pulmonary pleura

Back 19

The portion of the pleural serous membrane that is attached directly to the lung covering the surface of the lung and the fissures between its lobes.

Front 20

Visceral pericardium

Back 20

The serous membrane portion of the pericardial sac that is attached directly to the heart covering the surface of the heart.

Front 21

Parietal pericardium

Back 21

The portion of the pericardial serous membrane that is the outermost part of the pericardial sac, which is fused to and inseparable from the fibrous pericardium.

Front 22

Parietal peritoneum

Back 22

The abdominal serous membrane that forms the lining of the abdominal cavity or the coelom.

Front 23

Visceral peritoneum

Back 23

The abdominal serous membrane that is wrapped around the internal organs that are located inside the peritoneal space.
