Cell to cell communication

Hormones are used in ____ signaling.

• endocrine
• juxtacrine
• autocrine
• paracrine

This is an example of

• paracrine signaling
• synaptic signaling
• long-distance signaling
• all of the above

An example of DIRECT cell communication is:

• White blood cells bumping into each other sharing antigen info

• Neurons communicating across a synapse

• Hormones traveling through the blood stream to target tissues

An example of LONG-DISTANCE cell communication is:

• White blood cells bumping into each other sharing antigen info

• Neurons communicating across a synapse

• Hormones traveling through the bloodstream to target tissues

An example of LOCAL cell communication is:

• White blood cells bumping into each other sharing antigen info

• Neurons communicating across a synapse

• Hormones traveling through the blood stream to target tissues

what type of cell communication is being shown in the image?

• Paracrine

• Endocrine

• Juxtacrine

• Autocrine

What answer best describes the cell communication Autocrine?

• Cell responding to its own chemical message

• Cell responding to a neighboring cell

• Cell responding to hormones circulating in the blood

• Cells responding to signals sent by direct contact

Secret substances into interstitial fluid but affect only nearby cell

• Autocrine gland

• Endocrine gland

• Exocrine gland

• Paracrine gland

Contains specific receptors for a specific hormone to bind to & exert its effect

• Distress

• Eustress

• Stressor

• Target cell

Where does the ligand bind to initiate signal transduction?

• glycolipids

• nucleus

• phosphorylation cascade

• receptor
