Anatomy
Chapter one-introduction and organ systems
| Question | Answer |
|---|---|
| Anatomy | The study of the structure and shape of the body and its parts--comes from the greek word meaning "cutting open" |
| Gross Anatomy | the study of large, easily observable structures without the aid of a microscope |
| microscopic anatomy | the study of very small structures with the aid of a microscope |
| surface anatomy | the study of general form and superficial markings |
| physiology | the study of the function of structures--the study of how the body and its parts work or function |
| pathological physiology | changes in function resulting from disease |
| excercise physiology | studies physiological adjustments to exercise |
| 11 systems of the body | integumentary, skeletal, muscular, nervous, endocrine, cardiovascular, digestive, urinary, reproductive, lymphatic, respiratory |
| integumentary system | skin-forms the external covering of the body, protects deeper tissues, synthesizes vitamin D, location of nerve receptors |
| skeletal system | protects and supports body organs, provides muscle attachment for movement, stores minerals |
| muscular system | 760 muscles, allows locomotion, maintains posture, produces heat |
| nervous system | most complex system, fast acting control system, responds to internal and external short term changes, activates muscles and glands |
| endocrine system | sevretes regulatory hormones for growth reproduction and metabolism directly into the blood stream, slow moving system |
| cardiovascular system | transports materials in the body via blood pumped by the heart, transports oxygen carbon dioxide nutrients and wasts |
| digestive system | breaks down food, allows for nutrients to be absorbed into the blood stream, eliminates indigestible material |
| urinary system | eliminates nitrogenous waste, maintains acid-base balance, regulates materials such as water electrolytes and salts |
| reproductive system | production of offspring, embryology:the study of early developmental processes |
| lymphatic system | protects against infection, monitors the amount of blood in circulation |
| respiratory system | filters air, detects smell, conducts the passageway of aid, traps mucus, and site of gas exchange |
| pathology | study of disease |
| maintaining life | movement, locomotion, responsiceness, digestion |
| metabolism | chemical reactions that take place within the body that aid in the production of energy and maintain body structures |
| excretion | elimination of waste from metabolic reactions |
| reproduction | production of a future generation |
| growth | increasing of cell number and size |
| nutrients | provide the chemicals for energy and cell building |
| oxygen | required for chemical reactions |
| water | 60-80% of body weight is water |
| homestasis | maintenance of a stable internal environment or a dynamic state of equilibrium |
| homeostasis imbalance | a distrubance in homeostasis or disease |
| infection | colonization of pathological organisms |
| brain | recieves and analyzes information and determines the set point of a homeostatic disturbance |
| positive feedback | stops the original stimulus or reduces its intensity |
| negative feedback | increases the original stimulus to push the variable further, labor, blood clot |
| anatomical position | standing upright in the verical position, legs and feet parallel, arms hanging by sides, palms and face are firected forward, thumbs lateral |
| supine | lying face up with palms up |
| prone | lying face down with palms down |
| hypo | too little |
| hyper | too much |
| bilateral symmetry | equal right and left sides |
| parassagital symmetry | unequal left and right sides-not centered |
| cells | basic unit of structure and function in living things that may seve a specific function w/in organisms |
| tissues | made of cells that are similar in structure and function and work together to perform a specific activity |
| prgans | made up of tissues that work together to perform a specific activity |
| organ system | groups of two or more tissues that work together to perform a specific function for the organism |
| organisms | entire living things that can carry out all basic life processes. |
