Q

What characteristics distinguish epithelial tissues from other types?

A
  1. Polarity:
  2. Specialized contacts- cells fit closely together to form sheets of cells
  3. Supported by connective tissue- cells are attached to basement membrane
  4. Avascular but innervated- supplied by nerves but have no blood supply of their own
  5. Regeneration: can easily divide to regenerate tissue
