Another method to create new tissue uses an existing scaffold. While more traditionally considered engineering materials use linear models, biologically grown materials like the aorta require the use of nonlinear models, similar to paint and toothpaste, and are much more difficult to characterize. !BHY&:~. At the end of the dissection, there should be some hand-in, probably a combination of drawings and text, which shows that the student understands the object, and reassembled items should be inspected to show that they still work.

The changes in culture, society, and the medical curriculum have altered the environment, the focus, and the trends in teaching anatomy. Dissection is used to help to determine the cause of death in autopsy (called necropsy in other animals) and is an intrinsic part of forensic medicine.

Likewise, a dissection kit including all the tools required for dissection may be handed out, the students can be given the list but not the tools, or they may be required to determine independently what tools are needed. After choosing a device, the instructor must disassemble it and reassemble it several times to determine not only how the machine works, but also what tools are required for dissassembly and what parts of disassembly or reassembly are likely to be the most difficult for students. 0 How do tissue engineering and regenerative medicine fit in with current medical practices? << endstream endobj startxref 0000005218 00000 n endstream endobj 39 0 obj <>stream The use of dissection modules in undergraduate medical education not only permits better learning in anatomy but also familiarizes the students with concepts of professionalism, manual dexterity, teamwork, self and peer-evaluation, and ethics [7].

Almost any object can be dissected, but it is best to use objects that are basically mechanical in nature (an electric drill is good, but a calculator is not) and have a reasonable number of parts (3 is not enough; 50 is too many). Unfortunately, the condition is difficult to diagnose and can often be confused with an aneurysm based on current methods of detection, including an MRI, which leaves physicians with no choice but to perform surgery to physically observe the artery.
