Final answer:
Anterior refers to the C. front of the body or the direction toward the front, in contrast to posterior, which refers to the back. It is synonymous with ventral, especially when discussing body cavities such as the ventral cavity.
Step-by-step explanation:
Anterior refers to the C. front part of the body or the direction toward the front of the body. For example, in humans, the toes are anterior to the foot.
This is the opposite of posterior (or dorsal), which describes the back or direction toward the back of the body, such as the popliteus being posterior to the patella. In anatomical terms, anterior is equivalent to ventral.
When referring to the ventral cavity, it is described as the larger body cavity located anterior to the posterior (dorsal) body cavity, which includes the serous membrane-lined pleural cavities for the lungs, pericardial cavity for the heart, and peritoneal cavity for the abdominal and pelvic organs.
