LESSON 7 Flashcards
WHY DO CELLS COMMUNICATE?
DURING DEVELOPMENT AND CELL DIFFERENTIATION
WHY DO CELLS COMMUNICATE
CELLS NEED TO KNOW WHETHER TO LIVE, DIE OR DIVIDE
WHY DO CELLS COMMUNICATE
NEUROTRANSMISSION
REGULATION OF METABOLISM
Cells communicate through ___________
signaling molecules
The ____ molecule could be protein, lipids, hormones, growth factors, or neurotransmitters
signaling
T-CELLS
IMMUNE CELLS
TYPES OF CELL COMMUNICATION
Autocrine
Juxtacrine
Paracrine
Endocrine
Cells can sometimes produce signals that bind to receptors on their own surface
Autocrine signaling
It ensures correct cell division and maintaining their their cell identity
autocrine signaling
a cell that targets itself
autocrine signaling
Cells that are in direct contact or are very close communicate each other through gap junctions
(Juxtacrine signaling)
a cell targets a cell connected by gap junctions
juxtacrine signaling
Cells can send signals to other cells that are not connected
paracrine signaling
Signaling molecules are able to diffuse across short distances to pass the message
paracrine signaling
a cell targets a nearby cell
paracrine signaling
