Anatomy Ch 1 Test
| 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 |
| pleurae | lungs |
| peritoneum | abdominopelvic cavity |
| serous membrane/serosa | thin, double-layered membranes |
| paietal serosa | lines internal body cavity walls |
| visceral serosa | covers internal organs |
