When should radical neck dissection not be used?
Radical neck dissection should not be used when less invasive procedures can achieve the same therapeutic goals, such as modified radical neck dissection or selective neck dissection. It should also be avoided in cases where the risks of surgery outweigh the potential benefits, such as in patients with advanced age or significant comorbidities. Additionally, it may not be appropriate in cases where the patient's quality of life would be significantly compromised by the extensive removal of neck structures.
Can human cells live independently outside the body?
No, human cells cannot survive independently outside the body. They require the specific environment and support provided by the human body to function properly, including nutrients, oxygen, and waste removal. If removed from the body, human cells would eventually die.
Can bacteria express human genes?
Yes, bacteria can be genetically modified to express human genes. This is commonly done in biotechnology and genetic engineering for purposes such as protein production, drug development, and studying genetic diseases. The human genes are inserted into bacterial cells, which then produce the corresponding human proteins.

Can lymph nodes be removed?
Yes, lymph nodes can be removed surgically in a procedure known as lymph node dissection. This is often done to investigate or treat conditions such as cancer or infection. However, removal of lymph nodes can sometimes lead to complications related to lymphatic drainage and potential immune system impairment.

What is the importance of dissection?

What type of doctor does cadaver dissection for scientific research?
All medical schools in the United States include Gross Anatomy in the first year curriculum, and for many schools that entails cadaver dissection. It is deemed by many to be the "right of passage" for every first year medical student to endure on the path to become a physician, whether they become a surgeon or general practitioner. So pretty much every doctor has done cadaver dissection for research/educational purposes; however, many types of surgeons (especially plastic surgeons) use cadavers to hone their skills and to pass re-certification exams.
