A. Body regions: Anatomically, the human body is divided into eight regions. Directions: Assign a color to each region that is listed below. Color and label each region on the human body figure on the next page. 1. The cephalic region comprises the head and associated organs which are located at the top of the body. 2. The cervical region comprises the neck and the thorax, and associated organs. 3. The dorsal region comprises the back, from below the neck to the area below the waist, not including the shoulders. 4. The thorax comprises areas below the neck and ends just below the ribcage. 5. The abdomen covers the area covering the bottom of the ribcage up to the hips. 6. The pelvis begins at where the abdomen ends and covers the area between the hip bones. 7. The upper extremities include organs such as the shoulders and hands. 8. The lower extremities include the hips, buttocks, and legs. B. Body Cavities: Fluid filled spaces (other than blood and lymph vessels) are called cavities. Cavities in the human body are broadly divided into dorsal and ventral cavities. These cavities house internal organs and allow size and shape changes that occur during normal functioning of the body. Directions: Assign a color to each cavity and apply play dough or clay to your skeleton model where each cavity in bold below is located (total of 6 cavities will be represented. If you do not have a skeleton model, color and label the cavities on the attached skeleton): The Dorsal cavity is comprised of the cranial cavity and vertebral canal. The cranial cavity houses the brain, while the vertebral or spinal cavity houses the spinal cord. The Ventral cavity is comprised of the thoracic cavity and abdominopelvic cavity. The thoracic cavity houses the heart and lungs. The abdominopelvic cavity is further divided into abdominal cavity and pelvic cavity. The abdominal cavity houses the digestive organs, kidneys, and spleen, and the pelvic cavity houses the reproductive organs and urinary bladder.
