Q

what are the two types of ciliated epithelium ( based on motion)
, its characteristics and eg

A

kino ciliated: they keep in motion, microtubule arrangement in 9+2, and examples are tracheae, oviduct, ventricles of the brain

stereo ciliated: they are not in motion, arrangement of microtubule is 9+0 examples are inner ear
