Skin
Where is Lightly Keratinized epithelia found?
Esophagus & Vagina
What do Stereocilia and MicroVilli have in common?
Both are made up of a core of Actin Microfilaments and Actin-associated proteins
What is the difference between Stereocilia and Microvilli?
Stereocilia are longer, branch, and ends have endocytotic vesicles
