What type of tissue is transitional epithelium?
stratified tissue
Transitional epithelium is a stratified tissue in which the cells are all have a fairly round shape when the organ it lines is not distended (stretched out). The image shows the wall of the urinary bladder in the relaxed state (not distended).
Is transitional epithelium a connective tissue?
All transitional epithelial cells are covered in microvilli and a fibrillar mucous coat. The epithelium contains many intimate and delicate connections to neural and connective tissue. These connections allow for communication to tell the cells to expand or contract.
How do you identify transitional epithelium histology?
Transitional epithelium is an epithelial tissue which in a relaxed state appears as a stratified cuboidal epithelium. The cells in the transitional epithelium are pear-shaped or round, but as tissue is stretched, cells become flattened, giving the appearance of stratified squamous epithelium.
Where is transitional epithelial tissue found?
urinary bladder
Transitional epithelia are found in tissues such as the urinary bladder where there is a change in the shape of the cell due to stretching.
What are the transitional epithelial cells?
Transitional epithelium is a layer of cells that forms the mucosal lining of your ureters, a portion of your urethra, and your urinary bladder. These cells are called transitional because they can undergo a change in their shape and structure.
Why is transitional epithelium called transitional epithelium?
Lesson Summary Transitional epithelium is a layer of cells that forms the mucosal lining of your ureters, a portion of your urethra, and your urinary bladder. These cells are called transitional because they can undergo a change in their shape and structure.
Why transitional epithelium is called urothelium?
The transitional epithelium is also called urothelium because it lines urinary ducts, such as renal calyxes (2 cell layers), urethers (3 to 5 cell layers), urethra (4 to 5 cell layers) and urinary bladder (up to 6 cell layers). These cells form the impermeable barrier to diffusion between urine and blood.
Which of the following are characteristics of transitional epithelium?
Transitional epithelium is a stratified tissue made of multiple cell layers, where the cells constituting the tissue can change shape depending on the distention in the organ. When the organ is filled with fluid, cells on the topmost layer of this epithelium can stretch and appear flattened.
Why transitional epithelial tissue is called transitional?
What is the function of the transitional epithelial tissue?
The cells of the transitional epithelia are specialized to protect underlying tissues from the hypertonic and potentially cytotoxic effects of urine. The morphological features of the cells allow distension of transitional epithelium as the urinary bladder fills and stretches.
