Essay on White Rat Dissection Lab Report

A chest radiograph showed a rounded, well-defined soft tissue density measuring 4.5 x 4.2 cm located in the inferior aspect of the left hilum at the level of the mid chest. The chest x-ray was otherwise unremarkable. Computed tomography of the chest revealed a left hilar 3.2 x

The paws of the rat held resemblance to hands. The rat was probably around 2 years old. Its facial features and jaw suggested that its diet is that of an herbivore.

　　　　What organs are found in the body that rats have in common too? Of course, human organs are bigger than a rat. A rat’s body is tiny compared to the human body. What are those labeled organs are? The rat has a heart like any animal or human has. The heart pumps blood to circulate throughout the body. The rat has a heart in them too and with the same function as well. Rats have a heart so that they could have the blood circulated throughout their

These notes include the history of the animal, description of the veterinarian’s findings, description of what was seen before the animal was euthanized, weight and measurements of the animal, findings, and even photo-documentation. After laying the animal dorsally, the skin was cut the full length from the anus to the chin. All organs were then evaluated for any abnormalities, especially the heart and lungs in the thoracic cavity and the liver, kidneys, and spleen in the abdominal cavity. In collecting the spleen for histopathology, the appropriately sized and labeled containers which are filled with a suitable amount of 10% neutral buffered formalin (NBF) was retrieved, the tissue was removed from the carcass using forceps and scissors and was closely trimmed to remove fat and unnecessary connective tissue, cleaned of blood using saline to rinse it and placed in the container of

There is little definition between his chin and his neck. His ears are pointed and extend past the top of his head. Between his ears is a modest patch of hair. The individual strands are carved and appear to be straight. The patch on which the hair is carved is lighter and more yellow-toned than the rest of his skin.

At some point in the wall of the right atrium neighboring itself to the sinus venarum at the junction where the superior vena cava enters the right atrium, the SA node sits quietly. After sitting on a lab stool hunched over the clean, ebony tables, meticulously carving and stitching the heart, I had finally reached the point of the anatomy lesson that I had been waiting years to do.

It was noted that the frog and the rat had many different external structures. The amphibian had a nicotine membrane over its eye to protect the eyeball while under water. The amphibian also had a tympanic membrane, while the frog had ears. The skin of the organisms was observed: the frog had a smooth, slimy skin for swimming, while the rat had fur to keep it warm. The muscular system of the both seemed

The x-ray shows the boot-shaped characteristic. The aortic arch is on the right side. The boot-shaped is developed due to the upturning of the cardiac apex because the right ventricle hypertrophy and the concavity of the main pulmonary artery.

The heart contains four chambers, the right atrium, the left atrium, the right ventricle and the left ventricle. The right atrium is located in the upper right corner of the heart, above the right ventricle whereas the left atrium which is positioned in the left side of the heart separated from the right atrium and the left atrium. The atria has a very interesting texture, it has a thin, less muscular wall and is smaller in contrast to the ventricles. The atrium is joined to the veins that transport blood out to the heart and is categorized under the four hollow chambers of the heart. The left ventricle is situated in the bottom left portion of the heart. It lies under the left atrium separated by the mitral valve while the right ventricle is located in the lower right portion of the heart below the right atrium and opposite of the left ventricle. The aorta is the largest artery in the body; it begins at the top of the left ventricle. The right pulmonary artery begins at the base of the heart’s right ventricle. The left pulmonary artery passes horizontally in front of the descending aorta and left bronchus. The heart consists of four types of valves, the tricuspid valve located between the right atrium and the left ventricle, the pulmonary valve situated between the right ventricle and the pulmonary artery, the mitral valve positioned among the left atrium and the left ventricle and finally the aortic valve located between the left ventricle and the

The ventro-cranial area of the right lung lobes has a poorly demarcated mottling of black, green and yellow discolouration. The caudal area of the lung lobes is also discoloured with a disseminating mottling of black, green and yellow. The surrounding pleura has also been discoloured in a similar way. The lungs have multifocal, well demarcated, green discoloured circular areas.

Skull: When palpating the head, the skull is round anteriorly and posteriorly and posteriorly, no masses or indentions noted

pericardial cavity. The myocardium at this stage, however, does not completely surround the endothelial tube. Instead, it retains, in its dorsal aspect, continuity with the splanchnic mesoderm of the developing mediastinum, through the structure known as the dorsal

Purpose of this practical is to compare tissues in healthy spleen and thymus with unhealthy spleen and thymus of a mouse.
