Bell Work 4-6-18 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?

Play Dough Make Three – 3 dimensional little Men and wait for instructions.

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

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

Body Cavities Figure 1.9a

Body Cavities Figure 1.9b

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 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

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 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
