Vocabulary - Intro to A&P
| Term | Definition |
|---|---|
| Anatomy | The structure of body parts |
| Sagittal Plane | Median plane |
| Coronal Plane | Frontal plane |
| Transverse Plane | Horizontal plane |
| Axial Parts | Head, neck, and body |
| Appendicular Parts | arms and legs |
| Superior/Cranial | Towards the top |
| Inferior/caudial | Towards the bottom |
| Proximal | Towards the center (trunk) |
| Distal | Farther away from the center (trunk) |
| Physiology | How the parts function |
| Anterior | front, ventral |
| Posterior | back, dorsal |
| Medial | towards mid line |
| Lateral | away from mid line |
| Superficial | towards body surface |
| Deep | away from body surface |
| Frontal | plane divides body into anterior and posterior; also called coronal |
| Thoracic cavity | chest space |
| Pleural cavities | 2 spaces for lungs |
| Pericardial cavity | heart space; also inferior mediastinum |
| Superior mediastinum | space for esophagus, trachea superior and posterior to heart |
| Abdominopelvic cavity – space for digestive and urogenital organs; superior = abdominal; inferior = pelvic | space for digestive and urogenital organs; superior = abdominal; inferior = pelvic |
| Serosa | double membranes covering lining body cavities and organs (parietal= layer along cavity wall; visceral =- layer over organs) |
| Serous fluid | lubrication between visceral and parietal serosa |
| Chemical Bond | attractions between atoms or molecules |
| Chemical reaction | converts reactants to products by breaking and/or building bonds |
| Ion | charged atom due to gaining or losing electrons |
| Ionic bong | joined when electrons transferred from one atom to another to form ions |
| Covalent bond | atoms joined by sharing pair of electrons |
| Hydrogen bonds | attraction between a hydrogen and a polar atom |
| Polar compound | compound with partial positive and negative sides |
| Synthesis reaction | build new molecules; stores energy in chemical bonds |
| Decomposition reaction | break down molecules, release energy |
| Organic compound | compound with C-H bond |
| Acid | releases H+ ions and lowers PH |
| Base | Releases OH- ions and raises PH |
| pH | measuses H+ in concentration |
| buffer | resists pH changes |
