Final answer:
Curvid Iris and Potts-Smith scissors are used to dissect delicate tissues in surgical procedures, suitable due to their precise and gentle design. Dense connective tissues contain collagen, whereas blood, a type of connective tissue, does not.
Step-by-step explanation:
Curvid Iris and Potts-Smith scissors are frequently used to dissect delicate tissues. These scissors are designed to be precise and gentle, making them ideal for manipulating tissues that can be easily damaged, such as nerves or thin layers of muscle or connective tissue. In medicine, the correct tools must be used for different tissue types in order to ensure the best possible outcomes in surgical or investigative procedures.
Answering related review questions, muscle, nervous, and epithelial are types of tissues, while embryonic is not categorized as a type of tissue in the context given. Under the microscope, a tissue specimen with cells located in scattered spaces within a transparent background is most likely loose connective tissue. Dense connective tissue, whether regular or irregular, is characterized by its collagenous fibers, with regular being parallel and irregular being mesh-like. Additionally, the type of connective tissue that lacks collagen fibers is blood.
