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 |
