Anatomy&Physiology
| Question | Answer |
|---|---|
| Anatomy | The study of the structure of the body |
| Physiology | The study of the function of the body parts. Referenced systems directions, planes, cavities, and structural units. |
| Gross Anatomy | The study of the structures of the human body that can be seen, examined, and dissected with the naked eye. |
| Microscopic Anatomy | The study of biological structures that are too small to be seen with the unaided eye, requires magnification. |
| Histology | Is the branch of biology and medicine focused on the detailed study of tissues. |
| Cytology | Is the branch of science that studies individual cells and their structures, function, internal chemistry and life cycles. |
| Development Anatomy | Is the branch of anatomy that investigates the structural changes an organism undergoes throughout the life span of a single celled zygote. |
| Comparative Anatomy | Is the study of similarities and differences in the anatomical structures of different species. |
| Systemic Anatomy | Is an approach to studying gross anatomy that organizes the human body by functional organ systems. |
| Terms of Direction | Standardized medical terms used to describe the location of one body part relative to another. |
| Anatomical Planes | Are imaginary flat 2D surfaces passed through the body in standard anatomical position. |
| Body Cavities | Are fluid filled fluid internal spaces within the human body that house, protect and cushion internal organs. |
| Cranial Cavity | Formed by the skull bones, encloses and protects the brain. |
| Vertebral Cavity | Spinal - Formed by the bones of the vertebral column; encloses and protects the spinal cord. |
| Thoracic Cavity | Is enclosed by the ribs, chest muscles, and sternum. |
| Pleural Cavity | x2 each surround one lung. |
| Pericardial Cavity | Surrounds the heart. |
| Mediastinum | The central region between the lungs, containing the heart, esophagus, trachea, thymus, and the major blood vessels. |
| Abdominopelvic Cavity | Extends from the diaphragm down to the floor of the pelvis. |
| Posterior Body Cavity | Located near the back of the body. lined by protective membranes called meninges. |
| Anterior Body Cavity | Located near the front of the body, which is physically divided into two main sections by a dome-shaped skeletal muscle called the diaphragm. |
| Abdominal Cavity | Contains the stomach, liver, gallbladder, spleen, pancreas, small intestine, and most of the larger intestine. |
| Pelvic Cavity | Enclosed by the pelvic bone, contains the urinary bladder, reproductive organs and the rectum. |
| Serous Membranes | The walls of the ventral body cavity and the surfaces of the organs inside it are lined by a double layer of membrane that secretes lubricating serous fluid |
| Serous Fluid | Is a thin watery, slippery fluid produced by the serous membrane. This fluid helps reduce friction between organs and surrounding body parts. |
| Parietal Layer | Lines the outer wall of the body cavity |
| Visceral Layer | Covers the surface of the internal organs. |
| Pluera | Surrounds the lungs. |
| Pericardium | Surrounds the heart. |
| Peritoneum | Surrounds many abdominal organs. |
| Abdominal Quadrants | There are 4 quadrants; divided by a vertical line and a horizontal line that intersects at the umbilicus. |
| Umbilicus | Is an anatomical term for the navel or belly button. |
| Right Upper Quadrant | RUQ: Houses key organs like the liver, gallbladder, duodenum, head of the pancreas, right kidney, right adrenal gland, hepatic flexure of the colon. |
| Left Upper Quadrant | LUQ: Houses key organs like the stomach, spleen, body/tail of the pancreas, left kidney, left adrenal gland, and the splenic flexure of the colon. |
| Right Lower Quadrant | RLQ: Houses key organs like the cecum, appendix, ascending colon, right ovary, right fallopian tube/right spermatic cord, and right uterer. |
| Left Lower Quadrant | LLQ: Houses key organs like the sigmoid colon, descending colon, left ovary, and left fallopian tube/left spermatic cord, and the left uterer. |
