Epithelial tissue that can stretch or is subjected to stress would have many tight junctions?
Yes, epithelial tissue that needs to stretch or endure stress typically have many tight junctions. Tight junctions create a seal between adjacent epithelial cells, enhancing their structural integrity and preventing leakage of molecules through the gaps between cells. This is crucial for tissues like the bladder or the skin that need to expand and contract.
Which layer of the basement membrane of epithelial tissues is produced and secreted by cells of the underlying connective tissue?
The lamina densa layer of the basement membrane is produced and secreted by cells of the underlying connective tissue. This layer is primarily composed of collagen type IV fibers and serves as a sturdy foundation for the overlying epithelial cells.
Where in the body can you find epithelial tissue that is peculiar when compared to connective tissue?
The epithelial tissue is peculiar compared to connective tissue because it covers body surfaces and lines body cavities, whereas connective tissue mainly provides support and structure to the body. Epithelial tissue is found on outer surfaces like skin and inner linings like the digestive tract, while connective tissue is found throughout the body supporting organs and connecting tissues.
What criteria are used to classify epithelial tissues?
Epithelial tissues are classified based on the number of cell layers (simple or stratified) and the shape of cells at the apical surface (squamous, cuboidal, or columnar). Additional criteria include the presence of specialized structures such as cilia or microvilli.
Describe the structure of the main tissues of the body and their role in the functioning of two named body organs?
The main tissues of the body include epithelial, connective, muscle, and nervous tissues. Epithelial tissues cover and protect organs, such as the skin acting as a barrier to the external environment. Connective tissues provide support and structure to organs, like in tendons supporting muscles. Muscle tissues facilitate movement in organs such as the heart and skeletal muscles. Nervous tissue enables communication and coordination in organs like the brain and spinal cord.
Why would polarity be important to an epithelium?
Polarity in epithelial cells is important for maintaining the barrier function of epithelial tissues. It helps in the selective transport of molecules and ions across the epithelium and in separating the different compartments of the cell. Additionally, epithelial cell polarity is crucial for cell-cell communication and signaling within tissues.
What are the 4 levels of organazation in the body?
cell, tissue, organ, and organ system
How do you round 33.487 to three decimal places?
33.487 is already rounded to three decimal places. if it were 33.4829, which is four decimal places, you would round it to the nearest three DECIMAL places, which would be 33.487. So, the answer to your question is; 33.487 is already rounded to three decimal places.
What would a group of ciliated epithelial cells be called?
ciliated epithelial tissue
Which tissue would likely contain large amounts of anchoring junctions?
Epithelial tissues, such as skin and mucous membranes, would likely contain large amounts of anchoring junctions. Anchoring junctions help to hold adjacent cells together and provide structural support to tissues that experience mechanical stress or stretching.
What are three places that you would find fungus?
unicorns

Where is the epithelial tissue found in our bodies?
3 classes1. simple endoderm1 layer, few think upper layers dermisa. squamousb. cuboidalc. columman2. stratified ectodermmany layers thika. squamousb. columman3. gland endodermdistirctdig. gland (cottage cheese)-globular: not uniform in textureEpithelial is one of the four types of tissues in the body. There is also muscular, nervous, and connective tissues. The best way to describe epithelial tissues is that they occur in parts of the body that need protection from the external environment. An analogy would the be the tiles on the space shuttle.3 classes1. simple endoderm1 layer, few think upper layers dermisa. squamousb. cuboidalc. columman2. stratified ectodermmany layers thika. squamousb. columman3. gland endodermdistirctdig. gland (cottage cheese)-globular: not uniform in texture1- non penetrable to vessels 2- penetrated by nerves 3- lines cavities and surfaces 4- lie on basement membrane 5 compacted cells with little inter-cellular space.Characteristics of epithelial tissue: Epithelial tissue lies on a basement membrane. That means that underlying the cells that are the cellular component of the epithelial tissue, there is a layer of acellular ("a-" means not, so "acellular" means not cellular) material. This basement membrane can be thought of as a sticky layer to keep the epithelial cells attached to whatever underlies them. The bottom edge of the epithelial tissue abuts the basement membrane; this bottom edge is called the basal surface. The edge of the epithelial tissue that faces the lumen (or the outside world) is called the apical surface.Other characteristics:1. Cells within this tissue readily divide to make more cells. This helps this tissue recover after any sort of abrasions occur.2. This tissue does not have any vasculature. This means that there are no blood vessels within it. This should make sense, since epithelial tissue is likely to get damaged by material moving against it-- and you don't want to bleed everytime something bangs into your skin or everytime you swallow something rough.3. The cells within this tissue are firmly attached to each other. As a border-tissue, if the cells weren't adherent to one another, it would be a leaky border. This would be no good-- liquids from inside of us would drip out! Yuck! So the cells all make the type of junctions with each other called tight junctions.
What is 0.93 rounded to three decimal places?
Doesn't make sense because you only have 2 decimal places in the question. If you want the answer in three decimal places it would be 0.930 but that is not considered rounding.
