•
Ciliated pseudostratified columnar epithelium is the type of
respiratory epithelium found in the linings of the
trachea as well as upper respiratory tract, which allows filtering and humidification of incoming air. •
Non-ciliated pseudostratified columnar epithelia are located in the
prostate and membranous part of male
vas deferens. •
Pseudostratified columnar epithelia with stereocilia are located in the
epididymis. Stereocilia of the epididymis are not cilia because their cytoskeleton is composed of actin filaments, not microtubules. They are structurally and molecularly more similar to microvilli than to true cilia. •
Pseudostratified columnar epithelia are found forming the straight, tubular glands of the
endometrium in females. They are also found in the internal part of the
ear. ==Additional images==
