The layer of the epineurium that extends within the nerve to define the fascicles is termed the internal epineurium. Together, these two layers form the epineurium, which varies in thickness along the course of a nerve. The epineurium is usually most abundant around joints, as its function is to protect the nerves from stretching and subsequent injury.
In addition to the staple of basal cells, ciliated cells and goblet cells, the respiratory epithelium also contains brush cells, endocrine cells (or small granule cells, function not clear) , surfactant-producing cells (or Clara cells) , and serous cells. Epithelium and underlying lamina propria are called the mucosa. The lamina propria consists of loose connective tissue with many elastic fibres, which condense at the deep border of the lamina propria to form an elastic membrane.
