Crayfish Body: A Case Study

5. Using fine pointed scissors, carefully make a shallow incision in the clitellum. Make this incision to the side of the midline; this techniques will prevent you from cutting into the gut. NOTE: It is essential not to cut deeply during the dissection; you will damage the gut tissue. If you tear the gut, obtain another earthworm and start over.

Time out was performed and all information was accurate and confirmed. Skin marker is used to mark incision line. A #10 knife blade on a #3 handle is used to make a vertical suprapubic incision is made through the skin and linea alba extending from below the umbilicus to the symphysis. The rectus muscles are retracted with Richardson retractors to develop the prevesical space. Blunt dissection by the surgeon’s finger is used to reflect the peritoneum superiorly away from the dome of the

It’s second dorsal fin is also tall, but has a strongly concave rear margarine. The posterior edge of the anal fin is deeply notched. The dorsal side of the hammerhead is dark brown, light grey, or olive in color, fading to white on the underside. Juveniles may have dusky second dorsals, but adults do not have any markings.

Depending on the specific abnormality, the surgery may require incisions on the abdomen, the buttocks, or both.

Next I opened the abdominal cavity by making a shallow incision sufficient to cut the abdominal muscles and peritoneum while not cutting any deeper structures. Lifting up I continued to cut the abdominal wall from the dorsum and into the area of the xiphoid cartilage of the sternum and continued to cut the abdominal wall at its dorsal and caudal boundaries down to the inguinal region.

• Rib resection. This is the removal of a small rib bone near the thoracic outlet.

The Pfannenstiel incision is most typically used for cesarean dissection. This is a transverse incision typically carried out two fingers width above the pubic symphysis. The incision is made through the subcutaneous fat, then through the underlying fascia.6 The fascia is then separated from the abdominal muscle bellies, and the abdominal muscles are separated by finger dissection or sharp dissection if necessary.6 The periosteum is then opened with either finger or sharp dissection, and the intraperitoneal cavity is revealed.6 Operations that allow for finger dissection tend to have better outcomes than operations that use sharp dissection of muscle bellies and connective tissue. In the end, surgeons will separate all four layers of the abdominal muscles at the linea alba.6 The separation of abdominal muscles is likely to cause inhibition of the muscles immediately after surgery. Without proper rehabilitation, this inhibition may last for a prolonged period of time.

A Crayfish, which is also known as crawfish are freshwater crustaceans. That means they belong to the same family as lobsters, crabs, and shrimps. There are over 200 different types of crayfish species. They are found across the world besides Africa and Antarctica. Their life spans are quite short, they only live for two to three years.

Once the count is complete the surgeon then scrubs and is gown by the surgical technologist. The surgeon's hands are pulled slightly outside of the knitted cuff. The surgeon's preferred hand is gloved first. Grasp the glove under the cuff and spread the opening with your thumb held away from the glove or tucked securely under the cuff. Orient the glove so that the palm of the glove faces the person you are gloving. Once the surgeon is gowned and gloved, the patient is in the supine position and ready to be draped. The down sheet is placed first. With the surgeon on one side and surgical technologist on the other, the down sheet is opened. Not letting the drape touch the

It is distinguished from other fellow jellyfish from the shape of its bell, which looks cubic, hence the name box jellyfish. When someone talks about deadly box jellyfish, it is most likely that he/she refers to a particular species of box jellyfish known as Chironex fleckeri, which is also known as sea wasp. It has the most potent venom among box jellies or even among any other species known to man. Chinorex fleckeri is the largest among all box jellyfish. The bell itself can grow up to 30 centimeters in diameter, and its tentacles may extend up to 3 meters in length. It has up to a total of 60 tentacles, with a cluster of up to 15 tentacles on each (bottom) corner of its cubic bell. This species is almost transparent, making it even more dangerous, as it is difficult to notice its presence in the water. (Fenner,

When you think of fierce underwater creatures, the tiny shrimp may not come to mind among the water giants such as killer whales, the great white shark, manta rays, and others. But yet, when you are eating that scrumptious thing, don’t you find that shell a bit troublesome?

Signal crayfish has become widespread through Europe in the last century due to human activities. Signal crayfish poses a threat for the endemic noble crayfish in most of the European countries as a vector of the crayfish plague and competition. As an invasive species, signal crayfish can alter the energy flow of the ecosystem through the food webs since, as omnivorous, it can feed from several trophic level, modifying the ecosystem assemblage. On the other hand, the noble crayfish is endangered due to several factors like water pollution, ecosystem alteration and crayfish plague; consequently, their restauration may be not possible. Therefore, this review aims to compile the effects of the invasive signal crayfish in European freshwater

The area of skin to be removed will be marked with a pen. Using a small scalpel or scissors, the surgeon will gently cut around and under the lesion until it is completely removed. The lesion will be placed in a fluid and sent to the lab for examination. If necessary, bleeding will be controlled with a device that delivers heat (electrocautery). The edges of the wound may be stitched (sutured) together, and a bandage (dressing) will be applied. This procedure may be performed to treat a cancerous growth or a noncancerous cyst or lesion.

The techniques of the flapless procedure rely on the experience of the surgeon in predicting

As far as the procedure goes, a sewing machine is utilized to perform the operation. When the
