First, dissecting and cutting instruments have sharp edges and are used to cut, separate, incise, and excise tissues; they are further classified into sharp and blunt (Phillips, 2016). Second, debulking instruments are used to reduce the bulk of firm tissue; include chisels, curettes, rasps, osteotomes, and gouges. Third, the main purpose of grasping and holding instruments is to grasp the tissue in an atraumatic way, while it remains in a position to allow the surgeon to perform a maneuver, such as suturing (Philips, 2016). Fourth, clamping and occluding instruments are designed to apply pressure at some point during the surgical procedure. Fifth, closure and approximation instruments are required for suture or staple placement and include needle holders, crosshatched jaws, tungsten carbide jaws, staplers, clip appliers, and others.
The radiographs revealed the mass was some kind of fish. The veterinarian immediately proceeded with an emergency surgery. The patient was already anesthetized utilizing the use of isoflurane, by a face mask, proceeding to intubate the patient with a cuffless endotracheal tube. Due to the fact that avian species have a closed cartilage ringed trachea, the use of a
Do you have any past animal husbandry, care, and/or handling experience? If so, elaborate and be specific. As a Pet Care Specialist at PetSmart, I have responsibility for the proper housing of the animals, fish, and aquatic plants in the store, including making sure they have healthy and comfortable environments and preparing food for all animals according to their schedule. I am responsible for monitoring their behavior and making sure they do not express unusual behavior and that they get the best quality veterinary care when needed. This includes removing any dead fish from aquariums and observing the fish to identify any that need to be isolated due to
Part A: Osmosis practical task Aim: To observe the effects of osmosis in rhubarb cells. Hypothesis: Water will be extracted out of the cells in the salt solution causing the cells to look different to the cells in the freshwater solution. Materials: Rhubarb Distilled water in a dropping bottle Salt solution in a dropping bottle Microscope, slides, and coverslips Forceps and razor blades or scalpel Paper Towel Method: Clean and dry a slide and coverslip. Obtain a small sample of the red epidermal cells from the stalk of the rhubarb by carefully peeling away the layer with forceps. Prepare a wet mount slide of the rhubarb tissue in distilled water only.
Biomembrane is irrigated to remove any debris. Then entire void was filled with the graft, care taken not to overstuff the void as this will make closure of biomembrane difficult. The biomembrane was repaired with absorbable vicryl sutures if possible, otherwise the soft tissue over it was repaired making the membrane fall back into place covering the graft completely. Watertight fascial closure was done, followed by skin closure using nylon. Post operative protocol.
We recorded each whether or not the counter actually counted the fish and then determined the percent accuracy for each level of sensitivity. This is important to test before it is actually in real-life use because we need to know the accuracy of the counter itself so we know the limitations when we use the counter to calculate population sizes and migration patterns. We also collected valuable data regarding what happens to the counter when a fish stops swimming and just sits in the tunnel, when a fish swims into the tunnel and then turns around and swims out the same way it entered, or if the fish was swimming really fast or really slow (even though speed should not be a factor). We found that in some cases, if the fish has passed at least two out of the
A well known example of this is the infamous anglerfish (Lophiiformes). Anglerfish posess a modified dorsal fin, the illiceum, at the tip of which is a bulb, the esca, which contains symbiotic luminescent bacteria. This esca is used both as a light to guide the fish, but also to lure prey to the anglerfish’s mouth. (Munk, 1998). The Cookiecutter shark’s bioluminescent cells imitate the faint light of the surface above, camouflaging it when viewed from below and so allowing it to approach its prey without being seen.
The blades of the scissors could have cut or displaced organs inside of the worm Changing the shape or where the organs were found. In future dissecting a sharp scalpel should be used to cut just below the skin. Another source of error in the frog dissection is when pulling out the Fat bodies organs could have been dislodged and removed or moved so that they could not be found and labeled. In future dissections the fat body should be removed by cutting with scissors instead of pulling them out by hand.
Identification of fish larvae Larval fish identification in this study was mainly depended on literature description and book. These guides are the compilation of the obtainable description of larval stages of fish around the world which are a guide to commonly occurring larval stages of fishes in Kenyan Coastal Waters by Mwaluma et al., (2014) and the larvae of Indo-Pacific Coastal fishes: An identification guide to marine fish larvae by Leis and Ewart, (2000). There are 2 main characteristic used to identify fish larvae which include body and gut shape. 2.2.1. Body shape Description and the body shape of fish larvae are very useful for identification (Leis and Ewart, 2000).
