The dorsal body cavity contains the brain and spinal cord.   The pelvic cavity is the portion of the ventral body cavity inferior to the abdominal cavity.
The dorsal body cavity is subdivided into the cranial cavity, which contains the brain, and the spinal cavity, which contains the spinal cord. Ventral Body Cavity As embryological development proceeds, internal organs grow and their relative positions change.  For example, because they are inside body cavities, the lungs, heart, stomach, intestines, urinary bladder, and many other organs can expand and contract without distorting surrounding tissues or disrupting the activities of nearby organs. The dorsal body cavity contains the brain and spinal cord. A few organs, such as the kidneys and pancreas, lie between the peritoneal lining and the muscular wall of the abdominal cavity. Those organs are said to be retroperitoneal (retro, behind). The pelvic cavity is the portion of the ventral body cavity inferior to the abdominal cavity. The bones of the pelvis form the walls of the pelvic cavity, and a layer of muscle forms its floor. The pelvic cavity contains the last portion of the large intestine, the urinary bladder, and various reproductive organs FIGURE 1-11 Body Cavities. (a) The dorsal body cavity is bounded by the bones of the skull and vertebral column. The muscular diaphragm divides the ventral body cavity into a superior thoracic (chest) cavity and an inferior abdominopelvic cavity. A few organs, such as the kidneys and pancreas, lie between the peritoneal lining and the muscular wall of the abdominal cavity. Those organs are said to be retroperitoneal (retro, behind). The pelvic cavity is the portion of the ventral body cavity inferior to the abdominal cavity. The bones of the pelvis form the walls of the pelvic cavity, and a layer of muscle forms its floor. The pelvic cavity contains the last portion of the large intestine, the urinary bladder, and various reproductive organs Dorsal body cavity. The dorsal body cavity protects organs of the nervous system and has two subdivisions. The cranial cavity is the area within the skull and encloses the brain. The spinal (vertebral) cavity encases the vertebral column and spinal cord. Like the dorsal cavity, the ventral cavity has two subdivisions. The superior division is called the thoracic cavity. The thoracic cavity is surrounded by the ribs and muscles in the chest. It’s further su divided into lateral pleural cavities (each pleural cavity envelopes a lung) and the mediastinum. The mediastinum is the middle section of the chest cavity. The chest cavity contains the left and right lungs, which lie on either side of the heart. The heart is contained in the portion of the chest known as the mediastinum. The mediastinum contains all of the chest organs except the lungs. Organs located in the mediastinum include the heart, the aorta, the thymus gland, the chest portion of the trachea, the esophagus, lymph nodes and important nerves. The much larger ventral body cavity contains organs of the respiratory, cardiovascular, digestive, urinary, and reproductive systems. The relationships among the dorsal and ventral body cavities and their subdivisions are indicated in Figure 1-10 and shown in Figure 1-11. A few organs, such as the kidneys and pancreas, lie between the peritoneal lining and the muscular wall of the abdominal cavity. Those organs are said to be retroperitoneal (retro, behind). The pelvic cavity is the portion of the ventral body cavity inferior to the abdominal cavity. The bones of the pelvis form the walls of the pelvic cavity, and a layer of muscle forms its floor. The pelvic cavity contains the last portion of the large intestine, the urinary bladder, and various reproductive organs A body cavity is any fluid-filled space in a multicellular organism other than those of vessels (such as blood vessels and lymph vessels). The dorsal (posterior) cavity and the ventral (anterior) cavity are the largest body compartments. These cavities contain and protect delicate internal organs, and the ventral cavity allows for significant changes in the size and shape of the organs as they perform their functions. Add a comment.
