8/25/09 Introduction Organization of the Human Body Chemical - atoms, combine in variable ways to form molecules Cellular -molecules arranged into specific patterns or forms to form the cellular level Tissue - cells form tissue, collection of similar cells that perform a common function Organs - various tissues make up organs, stomach as example System Level - made up of different organs, very different functions that come together for one purpose Organismic Level - systems combine to make an organism Systems Integument system - skin, don’t need to know Skeletal system - how bones are formed, osseous tissue, beginning as cartilage, bone markings (file), function (protects the body), bones of the body Muscle system - muscles of the body, structure of muscle, function (produce motion), microstructure Nervous system - nerve cells, spinal cord, brain, function to respond to stimuli, formulate and produce response Cardiovascular system - heart and lungs, structure, how they are formed, blood vessel system, function to carry nutrients to all parts of the body Urinary system - kidneys, filters blood, gets rid of waste Respiratory system - bring in oxygen form the atmosphere, lungs Anatomical Names - Become familiar with the anatomical names* Planes of the Body - Frontal plane- separates anterior and posterior, can be transient, not fixed* - Transverse plane- superior and inferior, transient* - Sagittal plane- right and left, lateral medial, fixed, cannot move, equally divides body* - Parasagittal plane- separates the body into a right and left side, transient, don’t really use this one - Oblique plane- lies on an angle to all of the others, will never see again Directional Terms - Proximal/distal- extremities, shoulder is proximal to the elbow - Superior/inferior- trunk of the body, head is superior to the lung - Lateral/Medial- closer to the midline is medial - Definition slide*** o Anterior/posterior Toward the front/ toward the back o Ipsilateral/contralateral/bilateral Same side/opposite sides/on both sides o Superficial/deep Toward the service/away from the surface

o Parietal/visceral Pertaining to the outer wall of body cavity/ Pertaining to the covering of an organ (more deep) Membranes - Serous- lines a body cavity that is not open to the external environment o Lung slide- pleural cavity Parietal pleura- more superficial Visceral pleura- more deep o Always separated by a space - Mucous- lines a body cavity that does open to the external environment o Eyes, mouth, nose Cavities of the Body - Dorsal body cavity o Cranial portion o Vertebral portion - Ventral body cavity o Viscera of the body- all organs of the body o Thoracic cavity- heart and lungs o Abdominopelvic cavity (AP)- separated by the diaphragm, down through the pelvis Abdominal cavity- contains most of the digestive system Pelvic cavity- reproductive systems, some digestive Subdivisions of the Thoracic Cavity - Right and left pleural cavity o Surrounds lungs - Pericardial cavity
