Chapter 1- Structure & Function Flashcards
the study of internal and external structures of organisms and the relationship of its parts
anatomy
study of structures that need to be magnified
microscopic anatomy
study of structures that can be seen with the naked eye
macroscopic anatomy (gross anatomy)
study of the function of organisms and parts
physiology
structure-> function function eventually influences anatomy of organism
“form follows function”
“same standing”- relative constancy of the normal body’s internal environment
homeostasis
how is homeostasis maintained?
feedback loops
3 basic components of feedback loops and explain each one
- ) sensor: identifies element being controlled, sets change, generates signal to integrator
- ) control (integrator): sends signals to effectors
- ) effectors: responds to integrator
2 types of feedback loops?
negative & positive
negative feedback loop
opposes change to return to normal
ex: increase breathing to replace oxygen
positive feedback loop
temporarily amplifies change to return to normal
ex: labor
what type of feedback loop is the most common in the body?
negative
what is disease?
- means “not at ease”
- body does not function normally
the study of the transmission, frequency, distribution, and control of a disease
epidemiology
a disease that can be spread
communicable
a disease spread from person to person is considered…
contagious
study of disease
pathology
causes disease
pathogenic
infectious disease from medical facility
nosocomial
the prediction of the outcome of the disease
prognosis
what is the anatomical position?
standing, arms at side, palms forward
supine position
patient is on his/her back
prone position?
patient on his/her stomach
right and left sides are mirror images
bilateral symmetry
