Question | Answer |
---|---|
Positive Feedback | response enhances or exaggerates original stimulus (amplifying effect) |
Positive Feedback Ex | enhancment of labor contactions by oxytocin |
Negative Feedback | response reduces or shuts off original stimulus (changes in opposite direction of initial change) |
Negative Feedback Ex | regulation of body temp and blood glucose |
musclular system | movement, heat, posture (muscles) |
endocrine system | hormones (glands) |
lymphatic system | defense, WBC, fights illness |
cardiovascular system | heart/blood, movement of blood, O2+CO2 |
reproductive system | babies |
integumentary system | skin, protection |
skeletal system | structure, protection, blood pressure (bones) |
nervous system | senses, brain control center (brain) |
digestive system | nutrition, waste (stomach) |
respiratory system | breathing, O2 in & CO2 out (lungs) |
excretory system | waste - urine |
anterior/ventral | front of body |
posterior/dorsal | back of body |
superior | towards the top of the head |
inferior | towards the feet |
medial | toward the midline |
lateral | toward the outside/further from midline |
proximal | closer to the attachment of body |
distal | further away from attachment of the body |
intermediate | centered/middle |
superficial | towards/at the surface of body |
deep | away from surface of body |
anatomical postition | -standing position -feet forward -arms at side w/ palms up |
gross anatomy | anatomy that deals with structures visible to the naked eye |
microscopic anatomy | anatomy that relies on use of microscopes to examine body |
developmental anatomy | anatomy of structural changes from fertilization-maturity |
levels of structural organization | -chemical -cellular -tissue -organ -organ system -organism |
survival needs | -nutrients -oxygen -water -normal body temp |
necessary life functions | -maintaining boundries between internal & external environments -movement of body parts -responsiveness -digestion -metabolism -excretion -reproduction -growth |
homeostasis | maintence of relatively stable internal conditions despite continuous changes in environment; dynamic state of equilibrium |
planes of body | -sagittal plane (right & left) -frontal plane (anterior & posterior) -transverse (horizontal) plane (superior & inferior) |
paricarduim | heart |
