Chapter 4: Histology Flashcards

1
Q

How do different tissues arise from genetically identical cells?

A

They express their genes differently, allowing them to differentiate into the embryonic tissues that give rise to the adult tissues.

26
Q

Adipose is a type of ___ connective tissue.

A

specialized
