Why you report epithelial cells in female urine and not in male urine?
Epithelial cells in urine are often reported in female samples due to the higher likelihood of contamination from the female genital tract, where they are more abundant. In males, the presence of epithelial cells is less common and may indicate pathology, as the male urethra has a different structure and function. Thus, while both genders can have epithelial cells in urine, their significance and interpretation differ, leading to more routine reporting in females.
What organelles are found in epithelial tissues?
Epithelial tissues contain several organelles that support their functions, including microvilli for increased surface area and absorption, cilia for moving substances across the epithelial surface, and tight junctions for preventing leakage between cells. Additionally, they have abundant mitochondria to provide energy for active transport processes. Other organelles such as the endoplasmic reticulum and Golgi apparatus are present for protein and lipid synthesis and secretion.
What is the most abundant mineral in Arkansas?
Quartz is the most abundant mineral in Arkansas, particularly in the Ouachita Mountains. Arkansas is known for its quartz crystals, with the Mount Ida area being a popular destination for rockhounding enthusiasts.
Is mitochondria more abundant in human epithelial cells or in onion epidermal cells?
Yes. In an animal, more mitochondria is needed to allow movement and conduction. In plants, on the other hand, not only is the cell occupied by the large central vacuole, but it is also filled with many plastids such as chloroplasts. Because of this not a lot of mitochondria can fit in.
What is one of the most abundant bacteria in the human intestine A. Streptococcus pneumoniae B. E. coli C. Nitrogen-fixing bacteria D. Rhizobium E. Pseudomonas?
Steptococcus pneumoniae is in the lungs and not all the time, only when your sick. E. coli is in the intestines and is a benefitial resident (most of the time) nitrogen fixing bacteria are in the soil and plant roots.
Most abundant cell type in integument?
Epithelial
What is one of the most abundant bacteria in the human intestine?
E. coli
Is large amount of extracellular matrix a characteristic of epithelial tissue?
No, epithelial tissue is primarily composed of closely packed cells with minimal extracellular matrix. The extracellular matrix is more abundant in connective tissue, which provides structural support and anchorage for epithelial cells.
How do epithelial tissues receive nutrients?
Epithelial tissues receive nutrients through diffusion from nearby blood vessels or from the underlying connective tissue. Nutrients can also be transported through the epithelial cells via active transport mechanisms.
The most abundant cell type in bone is?
Osteocytes are the most abundant bone cell type comprising about 95% of all bone cells. Although relatively inert, they are capable of molecular modification and synthesis.

What are cells abundant within the large intestine called that produce large amounts of lubricating mucus to aid in the passage of feces to the end of the digestive tract?
goblet cells
Explain the structure of the ilium and its ultrastructure?
The ilium is the final section of the small intestine, characterized by its long, narrow, and highly folded structure, which increases the surface area for nutrient absorption. Its wall comprises four layers: the mucosa, submucosa, muscularis externa, and serosa. The mucosa features villi and microvilli, enhancing absorptive capacity through a brush border of epithelial cells, while the submucosa contains connective tissue and blood vessels. Under electron microscopy, the ultrastructure reveals tight junctions between epithelial cells, abundant mitochondria for energy, and specialized cells like Peyer's patches for immune function.
What year did jasper get its name?
Jasper was named in 1886 after the abundant mineral resources found in the area, particularly jasper stones.
Which blood vessels have elastic fibers?
Arteries contain elastic fibres. These are particularly abundant in the large conducting arteries, such as the aorta.
What is the most abundant mineral in Arkansas?
Quartz is the most abundant mineral in Arkansas, particularly in the Ouachita Mountains. Arkansas is known for its quartz crystals, with the Mount Ida area being a popular destination for rockhounding enthusiasts.
In a eukaryotic cell specialized for secretion of hormones which internal organelles would you expect to be particularly abundant?
In a eukaryotic cell specialized for hormone secretion, you would expect the Golgi apparatus and endoplasmic reticulum to be particularly abundant. These organelles are involved in the production, processing, and packaging of hormones before they are released from the cell. Additionally, secretory vesicles would also be abundant as they are responsible for transporting the hormones to the cell membrane for release.
