Ensure sterile technique and document each step care!.
5.1 Step‑by‑Step Procedure for Cat Dissection
Begin by reviewing the specimen’s labeling and confirming the correct cat. Position the animal on the dissection board, ensuring the ventral side faces upward. Use a scalpel to make a midline incision from the sternum to the pelvic region, carefully cutting through skin, subcutaneous tissue, and fascia. Retract the incision with forceps to expose the abdominal cavity. Identify the diaphragm, then proceed to the thoracic cavity by opening the thoracic inlet. Locate the heart, lungs, and major vessels, noting their arrangement. Carefully dissect the heart’s chambers, valves, and coronary arteries, documenting each structure. Next, expose the digestive tract: isolate the esophagus, stomach, small intestine, and large intestine, noting the pyloric sphincter and cecum. Continue with the urinary system by identifying the kidneys, ureters, bladder, and urethra. Examine the reproductive organs, distinguishing between male and female specimens. Finally, dissect the musculoskeletal system: separate the rib cage, spine, and major muscle groups, labeling each bone and muscle. Throughout the procedure, maintain sterile technique, use proper anatomical terminology, and record observations in the lab notebook. Conclude by cleaning the workspace and disposing of tissues according to institutional guidelines. Students should submit a detailed dissection report, including labeled diagrams, observations, and reflective analysis of anatomical variations observed during the procedure online ASAP Students master identification and documentation skills
