GROSS ANATOMY

Detailed explanation-1: -On a human body, dorsal (i.e., posterior) refers to the back portion of the body, whereas ventral (i.e., anterior) refers to the front part of the body. The terms dorsal and ventral are also often used to describe the relative location of a body part.

Detailed explanation-2: -Posterior or dorsal-back (example, the shoulder blades are located on the posterior side of the body). Medial-toward the midline of the body (example, the middle toe is located at the medial side of the foot).

Detailed explanation-3: -Toward the back (not rear): for the pig, dorsal is used; for humans, posterior may also be used. Toward the front/belly: for the pig, ventral is used; for humans, anterior may also be used.

Detailed explanation-4: -Superficial. Towards the surface of the body.

Detailed explanation-5: -The vertebral cavity encloses the spinal cord and is divided into five regions: the cervical, thoracic, and lumbar regions, and the sacrum and coccyx bones. The dorsal cavity is lined by the meninges, which encloses and protects the brain and spinal cord.
