The dorsal body cavity, which protects the fragile nervous system organs, has two subdivisions (See figure below, gold areas). The cranial cavity, in the skull, encases the brain. The vertebral, or spinal, cavity, which runs within the bony vertebral column, encloses the delicate spinal cord. The abdominal cavity contains the digestive viscera. The thoracic cavity contains the heart and lungs. The pelvic cavity contains the urinary bladder, reproductive organs and rectum.

Key Terms
Regional Terms in AnatomyRegional terms describe anatomy by dividing the parts of the body into different regions that contain structures that are involved in similar functions. Two primary terms are used to describe the main regions of the body:
These are the two basic categories of regional terms; however, many other terms are used to describe smaller regions within the axial and appendicular regions. For example, the brachial region consists of the arm as a part of the appendicular region, while the abdominal region consists of the abdomen as a smaller part of the axial region. The abdominal region is subdivided into even smaller regions based on different functions of groups of organs and tissues in that region. If a person is experiencing pain in one part of the abdominal region, then the smaller regional divisions can help determine the organs involved in the problem to better treat symptoms. Axes Describe Relative PositionsAnother method for describing region An axis uses a straight line between two parts of the body to describe a region of the body with linear direction. For example, blood can be said to flow Many types of axes can give regional direction. Any pair of corresponding directional terms can be combined to form an axis (such as proximal-distal for an appendage).
Different Directional AP Axes in Three Body Segments of a Horse: Axis (A) (in red) shows the AP axis of the tail, (B) shows the AP axis of the neck, and (C) shows the AP axis of the head. Axes give more clarity and detail for describing the location of an anatomical region. They are commonly used in both zoology and human anatomy, and can be paired with body planes to give even more detail to anatomical direction, region, and location. Which of the following is the correct regional term for calcaneal?Regional Terms for Specific Body Areas. Which of the following regional terms refers to the back of the knee?the popliteal region encompassing the back of the knee, the sural region encompassing the back of the lower leg, the calcaneal region encompassing the heel, the plantar region encompassing the sole of the foot.
Why are directional terms so important quizlet?Why are directional terms so important? They allow us to accurately describe the position of a human body. They enable us to identify an extreme anatomical variation in a human body.
Which usage of a directional term is correct the arms are lateral to the chest?A lateral orientation is a position away from the midline of the body. For instance, the arms are lateral to the chest, and the ears are lateral to the head. A medial orientation is a position toward the midline of the body.
