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.
The trunk of the body contains, from superior to inferior, the thoracic region encompassing the chest [1] the mammary region encompassing each breast; the sternal region encompassing the sternum; the abdominal region encompassing the stomach area; the umbilical region is located around the navel; the coxal region encompassing the lateral (side ...
The ventral (from Latin venter 'belly') surface refers to the front, or lower side, of an organism. [ 38 ] For example, in a fish, the pectoral fins are dorsal to the anal fin , but ventral to the dorsal fin .
The body of the penis is made up of three columns of tissue: two corpora cavernosa on the dorsal side and corpus spongiosum between them on the ventral side. The urethra passes through the prostate gland , where it is joined by the ejaculatory ducts , and then through the penis.
Hence, what is technically a transverse (orthogonal) section with respect to the body length axis of a rat (dividing anterior from posterior) may often be referred to in rat neuroanatomical coordinates as a coronal section, and likewise a coronal section with respect to the body (i.e. dividing ventral from dorsal) in a rat brain is referred to ...
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.
The hypaxial muscles are located on the ventral side of the body, often below the horizontal septum in many species (primarily fish and amphibians). In all species, the hypaxial muscles are innervated by the ventral ramus (branch) of the spinal nerves, while the epaxial muscles are innervated by the dorsal ramus.
Examples: The thumb is on the radial side of the hand (the same as saying the lateral side); the ulnar side of the wrist is the side toward the little finger (medial side). Ventral and dorsal, which describe structures derived from the front (ventral) and back (dorsal) of the embryo, before limb rotation.
