2. Bell Work
What is the horizontal plane that divides the body into a top half and a bottom half?
What are the direction terms that describe body parts close to a point of reference?
Body parts close to the midsagittal plane are called?
Body parts on the front of the body?
Body parts on the back of the body?

3. Play Dough

4. Standard
12) Outline the in-depth normal structure and function of the musculoskeletal, digestive, and cardio-respiratory systems, specifically as they relate to radiology. Review directions, planes, and sections of the body in order to perform radiographic images. Summarize appropriate medical text(s) in order to list signs and symptoms of common diseases and disorders associated with each system

5. Objective Learn Sections (Cavities) of the Body
Review digestive anatomy
Abdominopelvic Quadrants

8. Body Cavities
Dorsal cavity protects the nervous system, and is divided into two subdivisions
Cranial cavity is within the skull and encases the brain
Vertebral cavity runs within the vertebral column and encases the spinal cord
Ventral cavity houses the internal organs (viscera), and is divided into two subdivisions: - Thoracic and Abdominopelvic cavities

9. Body Cavities Pleural cavities – each houses a lung
Thoracic cavity is subdivided into pleural cavities, the mediastinum, and the pericardial cavity
Pleural cavities – each houses a lung
Mediastinum – contains the pericardial cavity, and surrounds the remaining thoracic organs
Pericardial cavity – encloses the heart

10. Body Cavities
The abdominopelvic cavity is separated from the superior thoracic cavity by the dome-shaped diaphragm
It is composed of two subdivisions
Abdominal cavity – contains the stomach, intestines, spleen, liver, and other organs
Pelvic cavity – lies within the pelvis and contains the bladder, reproductive organs, and rectum

11. Other Body Cavities
Oral and digestive – mouth and cavities of the digestive organs
Nasal –located within and posterior to the nose
Orbital – house the eyes
Middle ear – contain bones (ossicles) that transmit sound vibrations
Synovial – joint cavities

20. Game (Round 3) – Row Teams
Write on paper. Identify the body cavities. Use minor classification (not ventral / dorsal).
Where the spinal cord is
Where the lungs are
Where the stomach is
Where the ovaries are
Where the kidneys are
Where the brain is

21. Round 3 Answers Where the spinal cord is Vertebral
Where the lungs are Pleural
Where the stomach is Abdominal
Where the ovaries are Pelvic
Where the kidneys are Abdominal
Where the brain is Cranial
