Body Cavities Figure 1.9a

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

Body Cavities Figure 1.9b

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

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

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

Body Cavities In which cavity are the following organs found: Name both the major and minor divisions. Spinal cord Lungs Brain Liver Bladder Small intestine

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

Round 3 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
