What occurs in Paracrine Signaling? - Cells will release vesicles 
containing signaling ligand that will attach to nearby target cells.
What type of signaling is paracrine signaling? - Local Range 
Signaling
Where does paracrine signaling occur? - Many different types of 
cells and tissues
What is paracrine signaling important for? - Development and 
releasing of growth factors
What occurs in Synaptic Signaling? - An electrical signal is sent to 
the synapse and releases neurotransmitters packaged in vesicles 
that bind to the target cell.
What is a synapse - A small gap between the signaling cell and the 
target cell.
What is the signaling cell also known as? - Pre-synaptic cell
What is the target cell also known as? - Post-synaptic cell
What are ligand molecules released from neurons? -
Neurotransmitters
What type of signaling is synaptic signaling? - Local Range Singaling
Neurotransmitters have a ___________ __________and bind 
__________ to their target to cause a change in the target cell -
Rapid action, quickly
What occurs in autocrine signaling? - A cell signals itself and 
releases a ligand that binds to receptors on its own surface.
In which cell signaling does the cell act as the sender and receiver? 
- Autocrine signaling
What is autocrine signaling most commonly found in? - Immune cells 
and metastasis
What occurs in endocrine signaling? - Ligands are transmitted over 
long distances via the circulatory system.
What moves endocrine ligands around the body? - The circulatory 
system
What is the name of ligands released in endocrine signaling? -
Hormones
Will hormones bind to any cell they meet? - No, they will only bind to 
cells that have specific receptors
During endocrine signaling, hormones regulate what? Give 2 
examples. - Homeostatic mechanisms. 
Blood Pressure
Energy Metabolism
