Hematology, Pathology And Technology

Explanation
A mielocyte is a type of immature white blood cell that is found in the bone marrow. It is characterized by its large size and a large nucleus that takes up most of the cell's space. Mielocytes are part of the body's immune response and play a role in fighting infections. They eventually mature into granulocytes, which are a type of white blood cell involved in inflammation and immune responses. The arrow in the image is pointing to a cell that matches the description of a mielocyte, hence it is the correct answer.

Explanation
The correct answer is Metamielocyte because it is the only cell type mentioned in the options that could potentially be seen in the center. Metamielocytes are immature white blood cells that are found in the bone marrow and have a characteristic appearance. The other cell types mentioned, such as macrophages, epithelial cells, and fat cells, are not typically found in the center and are not related to the context of the question.

Explanation
The correct answer is "Mielocyte eosinophil" because it is the only option that is a type of eosinophil. Eosinophils are a type of white blood cell that are involved in the immune response, particularly in allergic reactions and parasitic infections. The other options, mature eosinophil, metamielocyte eosinophil, and platelet, do not refer to types of eosinophils.

Explanation
The correct answer is Bone marrow. A histological smear is a sample of tissue that is thinly spread on a slide and stained for microscopic examination. In the case of a bone marrow smear, a sample of bone marrow is collected and smeared onto a slide. This allows for the examination of the cellular components of the bone marrow, including red blood cells, white blood cells, and platelets. By examining the bone marrow smear, abnormalities in the production and maturation of these cells can be identified, aiding in the diagnosis of various blood disorders and diseases.

Explanation
Myeloid leukemia is the correct answer because it is a type of cancer that affects the bone marrow and blood. It is characterized by the overproduction of abnormal white blood cells, specifically myeloid cells. This condition can lead to symptoms such as fatigue, easy bleeding or bruising, and increased susceptibility to infections. The other options, lymphoid leukemia, lymphoma, and sepcemia, are not specific to the overproduction of myeloid cells and do not fit the given pathology.

Explanation
Impedance is a technology that measures the resistance of an electrical circuit to the flow of an alternating current. It is commonly used in various applications such as bioimpedance analysis, where it is used to measure the impedance of biological tissues. In the context of the given question, it is likely that the mechanism being referred to is one that utilizes impedance technology for some purpose, such as impedance-based cell counting or impedance-based detection of biomolecules. However, without further context, it is difficult to determine the exact mechanism being referred to.

Explanation
This machine is applying the technology of flow cytometry. Flow cytometry is a technique used to analyze and measure characteristics of cells or particles as they pass through a laser beam. It allows for the identification and quantification of different cell types based on their size, shape, and fluorescence properties. By analyzing the scattered light and fluorescence emitted by the cells, flow cytometry can provide valuable information about cell populations in a sample.
