Question | Answer |
---|---|
what is anatomy? | study of bodily structures and their relationships among the body parts. (the actual thing) |
what are the 3 types of anatomy? | 1. gross/macroscopic-LARGE 2. microscopic-VERY SMALL 3. developmental |
what is physiology? | study of how living organisms preform their vital functions. (function) |
gross anatomy: surface | study of general form and superficial markings |
gross anatomy: regional | focuses on organization of specific areas of the body (ex. arm and leg) |
gross anatomy: systematic | study of the structure of organ systems or group or groups of organs that function together in a conditional manner |
gross anatomy: developmental | describes the changes that occur between conception and physical maturity |
gross anatomy: clinical | includes a number of subspecialties important in the clinical practice (pathological, radiographic, and surgical) |
microscopic anatomy: cytology | analysis of the internal structures of an individual cell; or the study of cells |
microscopic anatomy: histology | examination/study of tissues |
developmental anatomy | traces structural changes throughout life |
what is embryology? | study of structural changes and processes that occur during THE FIRST TWO MONTHS OF DEVELOPMENT |
physiology: cell | study or function of cells |
physiology: organ | study of the physiology of specific organs |
physiology: systematic | includes all aspects of the functioning of specific organ systems |
physiology: pathological | study of the effects of diseases on organ or organ system function |
principle of complementarity | anatomical structure that usually reflects the function. (FORM FOLLOWS FUNCTION) |
levels of structural organization: chemical | atoms combine to form molecules |
levels of structural organization: cellular | molecules can interact to form various types of organelles, each with their own functions |
levels of structural organization: tissue | group of cells working together to preform one or more specific functions |
levels of structural organization: organ | made up of two or more tissues working in combination to preform several functions |
levels of structural organization: organ system | consists of different organs that interact and work closely together |
levels of structural organization: organismal | highest level of organization; made up of organ systems combined |
organ systems: integumentary | -largest system; covers the body - composed of hair, skin, nails, sweat and oil glands -protects deep tissues from injury and synthesizes vitamin D |
organ systems: skeletal | -composed of bone, cartilage, and ligaments -protects and supports body -framework for muscles -blood cell formation -stores minerals |
organ systems: muscular | -composed of muscle and tendons -allows manipulation, motion, and facial expressions -maintains posture -produces heat |
organ systems: nervous | -brain, spinal cord, and nerves (CNS) -fast-acting control system of the body -responds to stimuli by activating muscles and glands |
organ systems: endocrine | -pituitary gland, thyroid gland, pancreas, suprarenal glands, and gonads -directs long-term changes in bodily functions -adjusts metabolic activity and energy use by the body -controls many changes during development |
organ systems: cardiovascular | -heart, blood, and vessels -heart pumps blood -vessels disperse throughout body |
organ systems: lymphatic | -bone marrow, thymus, spleen, lymph nodes, lymphatic vessels, and tonsils -picks up fluid leaking from blood vessels and returns to blood -gets rid of waste on lymphatic stream -houses white blood cells (immunity) |
organ systems: respiratory | -nasal cavity, pharynx, trachea, bronchi, and lungs -keeps blood supplies with oxygen and removes carbon dioxide |
organ systems: digestive | -oral cavity, esophagus, stomach, both intestines, rectum, anus, and liver -breaks down food into absorbable units -eliminates indigestible food as feces |
organ systems: urinary | -kidneys, ureters, urinary bladder, and urethra -eliminates waste -regulates water, electrolytes, and pH balance of blood |
organ system: male reproductive | -prostate, penis, testicles, scrotum, and ductus deferens -produces offspring -testes make sperm and male sex hormones -ducts and glands deliver sperm to female reproductive tract |
organ system: female reproductive | -mammary glands, ovaries, vagina, uterine tubes and uterus -reproduction -ovary produces egg and female sex hormones -other part used for fertilization and housing developing fetus -mammary glands produce milk to nourish baby |
organ interrrelationships | basically, systems work together to preform tasks and maintain homeostasis |
what is homeostasis? | stable internal environment; a balance |
what are the two types of homeostasis? | -intrinsic regulation -extrinsic regulation |
what is intrinsic regulation? | when a cell, tissus, organ, organ system adjusts itself to Automatically respond to change |
what is extrinsic regulation? | when nervous or endocrine system must adjust activities...if auto doesn't work it kicks in to help |
what are the three regulatory mechanisms of homeostasis? | receptor, control center, and effector |
what is a receptor? | sensor that receives the stimulus |
what is a control center? | receives and processes the stimulus and sends out commands |
what is the body's control center? | the brain |
what is an effector? | cell or organ that responds to the commands of the control center and either enhances or opposes the stimulus |
what is negative feedback? | provides long term control over conditions and systems |
what is the primary mechanism of homeostatic regulation? | negative feedback |
what is an example of homeostatic regulation =? | thermoregulation |
what is the less common form of homeostatic regulation? | positive feedback |
what is positive feedback? | where the initial stimulus produces a response the exaggerates the change in original conditions rather than opposing it |
