Introduction Flashcards
anatomy
-describes structures of the body
-what the strucutres are made of
-where the strucutres are located
-associated structures
physiology
-study of functions of anatomical structures
-individual and cooperative functions
2 types of anatomy
-gross anatomy
-microscopic anatomy
gross anatomy
-macroscopic
-examines large visible strucutres
-Surface, regional, sectional, systemic, clinical and developmental
surface anatomy
exterior features
regional anatomy
-body areas
systemic anatomy
organ systems
clinical anatomy
-medical specialties
developmental anatomy
-from conception to adulthood including embryology
microscopic anatomy
-examines cells and molecules
-cytology (sudy of cells)
-histology (study of tissues)
signs vs symptoms
-signs are objective
-symtpoms are subjective
levels of organization
-chemical
-cellular
-tissue
-organ
-organ system
-organism
integumentary system mahor organs and functions
-skin, hair, sweat glands, nails
-protection from environment, regulation of body temperature, providing sensory information
skeletal system mahor organs and functions
-bones, cartilages, associated ligaments, bone marrow
-provide support and protection, store calcium and other minerals, form blood cells
muscular system mahor organs and functions
-skeleatl muscles and associated tendons
-provide movement, provide protection and support, generate heat that maintain body temp
nervous system mahor organs and functions
-brain, spinal cord, peripheralnerves, sense organs
-directs immediate responses to stimuli, coordinate or moderate activity of other organ systems, provide and interprets sensory info about external conditions
endocrine system major organs and functions
-pituitary gland, thyroid gland, pancreas, adrenal glands, gonads, endocrine tissues in other systems
-directs long term change in activity of other organ system, adjusting metabolic activity and energy use by the body
-control many structural and functional changes during development
cardiovascular system mahor organs and function
-heart, blood, blood vessel
-distribute blood cells, water and dissolved material
-distribute heat and assist in control of body temp
lymphatic system mahor organs and functions
-spleen, thymus, lymphatic vessel, lymph nodes, tonsils
-defend against infection and disease, return tissue fluids to the bloodstream
respiratory system mahor organs and functions
-nasal cavities, sinuses, larynz, trachea, bronchi, lungs, alveoli
-deliver air to alveoli, provide oxygen to blood, remove carbon dioxide from bloodstream, produce sounds for communication
digestive system mahor organs and functions
-teeth, tongue, pharynx, esocphagus, stomach, SI, LI, liver, gallbladder, pancreas
-process and digest food, absorb and conserve water, store energy reserve
urinary system mahor organs and functions
-kidneys, ureters, urinary bladder, urethra
-excrete waste from blood, control water balance, store urine, regulate blood ion concentration and pH
male reproductive system mahor organs and functions
-testes, epidydmus, ductus deferens, seminal vesicles, prostate, penis, scrotum
-produce male sex cells, seminal fluids and hormones, intercourse
female reproductive system mahor organs and functions
-ovaries, uterine tubes, uterus, vagina, labia, clitoris, mammary glands
-produce female sex cells and hormones, supports developing embryo from conception to delivery
-produce milk to nourish newborn infant, intercourse
what is medical terminology
-terms related to body in health and disease
-most commemorative (emponyms) have been replace by precise
surface anatomy
-locatin structures on or near the body surface
-can be felt or palpated
-anatomical directions help map findings
anatomical position
-hands at sides, palms forward,
supine
-lying down, face up
