A body cavity is any space or compartment, or potential space, in an animal body. Cavities accommodate organs and other structures; cavities as potential spaces contain fluid. The two largest human body cavities are the ventral body cavity, and the dorsal body cavity. In the dorsal body cavity the brain and spinal cord are located.
Ventral body cavity. The ventral body cavity is a human body cavity that is in the anterior (front) aspect of the human body. [1] It is made up of the thoracic cavity, and the abdominopelvic cavity. The abdominopelvic cavity is further divided into the abdominal cavity and pelvic cavity, but there is no physical barrier between the two.
These two terms, used in anatomy and embryology, describe something at the back (dorsal) or front/belly (ventral) of an organism. [2] The dorsal (from Latin dorsum 'back') surface of an organism refers to the back, or upper side, of an organism. If talking about the skull, the dorsal side is the top. [38] The ventral (from Latin venter 'belly ...
The abdominopelvic cavity is a body cavity that consists of the abdominal cavity and the pelvic cavity. [1] The upper portion is the abdominal cavity, and it contains the stomach, liver, pancreas, spleen, gallbladder, kidneys, small intestine, and most of the large intestine. The lower portion is the pelvic cavity, and it contains the urinary ...
The dorsal body cavity is located along the dorsal (posterior) surface of the human body, where it is subdivided into the cranial cavity housing the brain and the spinal cavity housing the spinal cord. The brain and spinal cord make up the central nervous system. [1] The two cavities are continuous with one another. [2] The covering and ...
FMA. 9680. Anatomical terminology. [edit on Wikidata] In human anatomy, the spinal canal, vertebral canal or spinal cavity is an elongated body cavity enclosed within the dorsal bony arches of the vertebral column, which contains the spinal cord, spinal roots and dorsal root ganglia. It is a process of the dorsal body cavity formed by alignment ...
The abdominal cavity is a large body cavity in humans [1] and many other animals that contain organs. It is a part of the abdominopelvic cavity. [2] It is located below the thoracic cavity, and above the pelvic cavity. Its dome -shaped roof is the thoracic diaphragm, a thin sheet of muscle under the lungs, and its floor is the pelvic inlet ...
Thoracic diaphragm. The thoracic diaphragm, or simply the diaphragm (/ ˈdaɪəfræm /; [1] Ancient Greek: διάφραγμα, romanized: diáphragma, lit. 'partition'), is a sheet of internal skeletal muscle [2] in humans and other mammals that extends across the bottom of the thoracic cavity. The diaphragm is the most important muscle of ...
