| Question | Answer |
| Anatomy levels of organization | Chemical Cellular tissue organs organ system organism |
| Chemical level | atoms and molecules |
| molecule | 2 or more atoms joined together |
| tissue | groups of cells working together to perform function |
| 4 types of tissues | epithelial connective muscular nervous |
| organ level | 2 or more tissues recognizable shape |
| system | group of organs common function |
| organism | most complex all parts and systems |
| how many systems of the body? | 11 |
| I S M N E C D R U R L | I still miss nice elephants, cats, dogs, roosters under rocky ledges |
| I | integumentary |
| S | skeletal |
| M | muscular |
| n | nervous |
| e | endocrine |
| c | cardiovascular |
| d | digestive |
| r | respiratory |
| u | urinary |
| r | reproductive |
| L | lymphatic |
| Life processes | living vs nonliving |
| life processes | metablism catabolism anabolism responsiveness movement growth differentiation reproduction |
| Homeostasis | body's internal environment remains within a sameness |
| 2 systems that try to maintain homeostasis | nervous endocrine |
| loss of homeostasis | stressor(disrupts)>monitored variable(detects)>controlled condition>feedback loop |
| negative feedback loop | works to reverse most feedback systems ex: blood pressure |
| positive feedback loop | reinforces/strengthens ex: labor |
| homeostatic imbalance | results in disease or disorder |
| disease | signs and symptoms |
| signs | objective ex: fever, swelling, rash |
| symptoms | subjective ex: headache, nausea |
| major body regions | head neck trunk upper limbs lower limbs |
| superior/cranial | toward head |
| inferior/caudal | away from head |
| posterior/dorsal | back |
| medial | near midline |
| lateral | further midline |
| ipsilateral | same side |
| contralateral | opposite side |
| proximal | nearer attachment |
| distal | further attachment |
| superficial/external | towards surface |
| deep/internal | away from surface |
| prone | face down |
| supine | face up (on spine) |
| body planes | saggital frontal transverse oblique |
| saggital | midsagittal - midline parasaggittal - unequal |
| frontal/coronal plane | front to back |
| transverse/cross sectional | superior to inferior |
| oblique plane | any angle other than 90 |
| 4 body cavities | 1. cranial 2. vertebral 3. thoracic 4. abdominal |
| thoracic cavity | superior to diaphragm lungs/heart |
| abdominopelvic | inferior to diaphram stomach, liver, intestines |
| abdominopelvic regions | |
| abdominopelvic quadrents |
