Superior and inferior are two anatomical terms that describe the location of different structures of the body. In humans, the head is the most superior anatomical structure of the body.
Figure 1: Superior and Inferior. Additionally, this term can be used to give the relative position of a particular anatomical structure of the body based on the altitude. For example, the neck is located superior to the chest. The term can describe the structures located below the body. Moreover, the anatomical position the most inferior part of the human body is the feet. The thoracic cavity is bound laterally by the ribs covered by costal pleura and the diaphragm caudally covered by diaphragmatic pleura.
The lower part of the ventral abdominopelvic cavity can be further divided into two portions: abdominal portion and pelvic portion. The abdominal cavity contains most of the gastrointestinal tract as well as the kidneys and adrenal glands. The abdominal cavity is bound cranially by the diaphragm, laterally by the body wall, and caudally by the pelvic cavity. The pelvic cavity contains most of the urogenital system as well as the rectum.
The pelvic cavity is bounded cranially by the abdominal cavity, dorsally by the sacrum , and laterally by the pelvis. The smaller of the two main cavities is called the dorsal cavity. As its name implies, it contains organs lying more posterior in the body. The dorsal cavity, again, can be divided into two portions.
The upper portion, or the cranial cavity , houses the brain , and the lower portion, or vertebral canal houses the spinal cord.

Anatomical position is the description of any region or part of the body in a specific stance. In the anatomical position, the body is upright, directly facing the observer, feet flat and directed forward. This stance should be very familiar to you. If the anatomical position is placed face-down, it is in the prone position.
If the anatomical position is placed face-up, it is in the supine position. Like you use the cardinal directions to explain the location of certain regions north, northwest, southeast, etc. An imaginary vertical line that divides the body equally right down the middle. In many instances, these terms can be paired. For example, a posterosuperior view combines the posterior and superior, giving us a view in which we are looking down at the back of the body, like so:.
