The islets of Langerhans are found in pancreas that make the hormones insulin and glucagon. The alpha cells make glucagon and beta cells to produce insulin.

Hyaline means transparent. It is found on many joint surfaces.

the shape of outer ear is like a funnel and it is so as to catch the maximum frequency possible.

hearing impairment can occur due to damage of ear canal.

Tympanic membrane is other name of eardrum.

The epiglottis is a flap that is made of elastic cartilage tissue covered with a mucous membrane attached to the entrance of the larynx. It prevents entry of food in the windpipe.

Trachea is called a windpipe.It is a wide, hollow tube that connects the larynx (or voice box) to the bronchi of the lungs. It is an integral part of the body’s airway and has the vital function of providing air flow to and from the lungs for respiration.

 The Malpighian corpuscle lies in the cortex.They are also known as Renal corpuscles — the initial filtering component of nephrons in the kidneys.

The terminal bronchioles initially have a ciliated columnar epithelium that soon transits to a low cuboidal epithelium.

The basal lamina is a layer of extracellular matrix secreted by the epithelial cells, on which the epithelium sits. It is the thinnest layer.

A pseudostratified epithelium is a type of epithelium that, although comprising only a single layer of cells, has its cell nuclei positioned in a manner suggestive of stratified epithelia.

Reticular and fibrous lamina are visible under electron microscope.

Endothelium of blood vessels and mesothelial lining of coelomic cavities can be classified under squamous epithelium.

The 'Brush Border' of intestines is an example of simple epithelium.

The term given to the single layered epithelia is simple epithelium.
