Unformatted text preview: 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...
