Which crystals can form in Alkaline urine?

A.

Amorphous phosphates
B.

Calcium Oxalate
C.

Struvite
D.

Amorphous urates
E.

Ammonium biurate
F.

Cystine
G.

Triple Phosphate

Correct Answer(s)
A. AmorpHous pHospHates
C. Struvite
E. Ammonium biurate
G. Triple pHospHate

Explanation
Certain crystals can form in alkaline urine due to the presence of specific substances. Amorphous phosphates, struvite, ammonium biurate, and triple phosphate are all examples of crystals that can form in alkaline urine. Amorphous phosphates are composed of calcium and phosphate and can be seen in alkaline urine. Struvite crystals are composed of magnesium, ammonium, and phosphate, and they typically form in the presence of urinary tract infections. Ammonium biurate crystals are formed from the breakdown of uric acid and are commonly seen in alkaline urine. Triple phosphate crystals, also known as magnesium ammonium phosphate crystals, can form in alkaline urine and are often associated with urinary tract infections.

What kind of crystals can be seen in animals with ethylene glycol toxicity?

A.

Ammonium biurate
B.

Monohydrate calcium oxalate
C.

Amorphous urates

Correct Answer
B. Monohydrate calcium oxalate

Explanation
Monohydrate calcium oxalate crystals can be seen in animals with ethylene glycol toxicity. Ethylene glycol is metabolized into oxalic acid, which then combines with calcium to form calcium oxalate crystals. These crystals can accumulate in the kidneys and other organs, leading to renal damage and other complications. Ammonium biurate and amorphous urates are not specifically associated with ethylene glycol toxicity.

What kind of cell is this?

Correct Answer
Squamous Epithelial Cell

Explanation
This cell is a squamous epithelial cell. Squamous epithelial cells are flat and thin, resembling scales or plates. They are found in the lining of various organs and body cavities, such as the skin, lungs, and blood vessels. These cells provide protection, secretion, and absorption functions depending on their location in the body.

What kind of cells are seen here?

Correct Answer
Epithelial Cells, Renal Tubular Epithelial Cells, Epithelial cell

Explanation
The image shows cells that have a distinct epithelial cell morphology. These cells are arranged in a single layer and have a polygonal shape with clearly defined borders. Additionally, some cells have a brush border on their apical surface, which is a characteristic feature of renal tubular epithelial cells. Therefore, the correct answer is Epithelial Cells and Renal Tubular Epithelial Cells.

WTF is that?!

Correct Answer
Fat Droplets, Lipids

Explanation
The correct answer is Fat Droplets and Lipids. Fat droplets are small globules of fat that are found in various tissues of the body. Lipids are a broad group of organic compounds that include fats, oils, and other substances. Both fat droplets and lipids are related to each other as fat droplets are composed of lipids.

What are these?

Correct Answer
Red Blood Cells, Erythrocytes, RBCs

Explanation
These terms refer to the same thing, which are the cells in our blood that carry oxygen to the body's tissues. They are called red blood cells because they contain a protein called hemoglobin, which gives them their red color. Erythrocytes is the scientific term for red blood cells, and RBCs is the abbreviation for the same.

. What kind of cell is marked in white?

Correct Answer
Renal Tubular Epithelial Cell, Eputhelial Cells

Explanation
The correct answer is Renal Tubular Epithelial Cell. This is because the question asks for the specific type of cell that is marked in white, and the only option that mentions a specific type of cell is Renal Tubular Epithelial Cell. The other options simply mention "Epithelial Cells" or "Epithelial Cell" without specifying a particular type. Therefore, the correct answer is Renal Tubular Epithelial Cell.
