o Anatomical position: body position that is commonly used as a reference. o Plane: imaginary flat field that is used as a point of reference for viewing 3d objects. 3 Major Planes: Frontal/coronal: vertical plane dividing the body anteriorly and posteriorly. Sagittal: vertical, dividing body between left and right positions. Transverse: horizontal dividing superior and inferior positions (top and bottom). o Regions: areas named to give workers the ability to communicate problems. Thoracic: area of the chest. Abdominal: area of the abdomen. o Body Quadrants: Right upper (RUQ) Left upper (LUQ) Right lower (RLQ) Left lower (LLQ) o Trunk: torso o Appendages: limbs o Cavities: spaces partially filled with organs. Dorsal cavity: Cranial cavity Spinal cavity
Exam #1 Notes Hannah Huffman Ventral cavity: anterior part of the body Diaphragm: divides ventral cavity into upper and lower cavities. o Thoracic cavity (superior) Pericardial cavity: along midline 2 Pleural cavities Mediasternum: contains the heart, large blood vessels above the heart, and the thymus gland. o Abdominopelvic cavity (inferior) Abdominal cavity (upper part) Contains liver, pancreas, spleen, most of the small and large intestines. Pelvic Cavity (lower part) Contains urinary bladder, internal reproductive organs, parts of small and large intestines. o Viscera: organs filling the cavities. o Disease: state of the body in which homeostasis has faltered due to any cause. o Pathology: the study of a disease. o Diagnosis: identification of an illness. o Symptoms: experiences of a patient resulting from a disease. o Sign: finding that can be discovered by an objective examination, such as a physical or lab exam. o Acute: disease of short duration. o Chronic: diseases that are of long duration. o Infection: disease caused by organisms such as bacteria, viruses, fungal parasites, or protozoans. o Etiology: the cause of a disease. o Trauma: physical injury. o Traumatic disease: disease resulting from trauma. o Prognosis: prediction of the probable course and probable outcome of a disease. o Diagnostic imaging: noninvasive procedures to observe the internal structures and functions of the body. Endoscopy, CT scan, PET scan, MRI, ultrasound. Endoscopy: long, flexible tube inserted into a patient. CT scan (computed tomography scanning): combines multiple x-rays, and computer enhancement to produce 3d images of internal body structures. PET scan (positron emission tomography): procedure that detects the journey of a radioactive-labeled substance (such as glucose) through the body and creates an image by tracking that pathway (to reveal areas that have a high metabolic rate such as tumors). MRI (magnetic resonance imaging): magnets that respond to hydrogen atoms in the body by sending signals to a computer to create a 3d image. Can diagnose forms of cancer, joint disease, and trauma.
