What tissue type has polarity and is avascular?

What tissue type has polarity and is avascular?

What tissue type has polarity and is avascular? Epithelia have polarity, which is to say that there is directionality. There is always an exposed surface and an attached surface. Epithelia are also avascular.

Where is reticular connective tissue found?

Reticular tissue, a type of loose connective tissue in which reticular fibers are the most prominent fibrous component, forms the supporting framework of the lymphoid organs (lymph nodes, spleen, tonsils), bone marrow and liver.

Which tissue type is avascular quizlet?

(3) Cartilage is avascular (blood vessels and underlying connective tissue do not penetrate the basement membrane), so materials needed for repair must diffuse from surrounding tissue.

Which of the 4 tissue types can be described as avascular?

1. All epithelial tissue is avascular, acquiring nutrients through diffusion or absorption. 2. The four primary tissue types are epithelium, connective tissue, muscle and nervous tissue.

What type of tissue is ligaments?

fibrous connective tissue
A ligament is a fibrous connective tissue that attaches bone to bone, and usually serves to hold structures together and keep them stable.

What type of tissue is a tendon composed of?

dense fibrous connective tissue
A tendon is composed of dense fibrous connective tissue made up primarily of collagenous fibres.

Where squamous epithelium is found?

Simple squamous epithelia are found lining the cavities of the body including the pericardial, pleural, and peritoneal cavities, or in areas where passive diffusion occurs, such as glomeruli in the kidney and alveoli in the respiratory tract.

Which of the following mammalian tissues is associated with filtration and diffusion?

Simple squamous epithelia are found in capillaries, alveoli, glomeruli, and other tissues where rapid diffusion is required. Cells are flat with flattened and oblong nuclei. It is also called pavement epithelium due to its tile-like appearance. This epithelium is associated with filtration and diffusion.

What type of cells are found in reticular connective tissue?

The cells that make the reticular fibers are fibroblasts called reticular cells. Reticular connective tissue forms a scaffolding for other cells in several organs, such as lymph nodes and bone marrow.

What tissues are reticular fibers found in?

The reticular fibers are made up mainly of type III collagen (100-150 nm in diameter) synthesized by special fibroblasts, reticular cells. Reticular fibers crosslink, forming a fine meshwork. The reticular connective tissues are found in the kidney, the spleen, lymph nodes, and bone marrow.
