Intro to A&P
| Question | Answer |
|---|---|
| Anatomy | The study of internal and external structures of the body and the physical relationships between them. |
| Physiology | The study of hope organisms perform their vital functions |
| Gross anatomy | |
| Examines large visible structures | |
| Surface anatomy | Exterior features |
| Regional anatomy | Body areas |
| Sectional anatomy | Cross section |
| Systemic anatomy | Organ systems |
| Clinical anatomy | Medical specialties |
| Developmental anatomy | Embryology |
| Microscopic anatomy | Examines cells and molecules |
| Cytology | Study of cells |
| Histology | Study of tissues |
| Cell physiology | Function of cells |
| Organ physiology | Function of specific organs |
| Systemic physiology | Functions of organ systems |
| Pathological physiology | Effects of disease on organs or systems |
| Signs/symptoms | Fever/tiredness |
| Scientific method | -form hypothesis -test hypothesis |
| Chemical level | -atoms -molecules |
| Cellular level | Cells (smallest loving units in the body) |
| Tissue level | A group of cells working together |
| Integumentary system major organs | -skin -hair -sweat glands -nails |
| Integumentary functions | -protection -regulate body temp -provides sensory information |
| Skeletal major organs | -bones -cartilages -associated ligaments -bone marrow |
| Skeletal functions | -support -stores calcium and minerals -forms blood cells |
| Muscular system functions | -provides movement -protection/support -generated heat and maintains body temperature |
| Nervous major organs | -brain and spinal cord -peripheral nerves -sense organs |
| Nervous functions | -response to stimuli -coordinates other systems -interprets sensory information |
| Endocrine major organs | -pituitary, thyroid, adrenal gland, pancrease, gonad |
| Endocrine function | -adjusts metabolic activity and energy use -controls changes during development |
| Cardiovascular major organs | -heart -blood -blood vessels |
| Cardiovascular functions | -distributes blood cells, water, nutrients,waste, oxygen and carbon dioxide -distributes heat |
| Lymphatic major organs | -spleen -thymus -lymphatic vessels -lymph nodes -tonsils |
| Lymphatic functions | -defend against disease and infection |
| Respiratory major organs | -nasal cavities -sinuses -larynx -trachea -bronchi -lungs -alveoli |
| Respiratory functions | Delivers air, provides oxygen to bloodstream, removed carbon dioxide from bloodstream, produces communication (speech) |
| Digestive major organs | -teeth -tongue -pharynx -espophagus -stomach -small intestine -large intestine -liver -gallbladder -pancreas |
| Digestive functions | -digest food -absorbs nutrients -stores energy |
| Urinary major organs | -kidneys -ureters -urinary bladder -urethra |
| Urinary functions | -excrete waste products from the blood -controls water balance by regulations volume of urine -stores urine -regulates PH |
| Autoregulation | Automatic response in acell, tissue or organ to and environmental change |
| Extrinsic regulation | Responses controlled by nervous and endocrine systems |
| A homeostasis regulator mechanism consists of? | -receptor (receive stimulus) -control center (processes and send instructions) -effector (carries out instructions) |
| Set point | Desired value for homeostasis |
| Negative feedback | -the response of effector takes care of stimuli -body normalizes |
| Positive feedback | -initial stimulus produces a response that amplifies the original change in conditions -body is moved away from homeostasis -normal range NOT retained -completes a dangerouz process quickly (repairing lacerations) |
| Disease | Caused by the failure to maintain homeostasis |
