CELL COMMUNICATION Flashcards
a fundamental process that allows
cells to coordinate their activities
and respond to environmental
changes.
Cell Communication
Cells communicate through ______ _______, which trigger specific cellular
responses.
signaling molecules
Cell communication
is essential for processes such as
_______, ________ ________, and
____________.
growth, immune responses, and
homeostasis.
how cells respond and connect to one another in order to work together
Cell Communication
Communicates through signaling molecules
Cells
communication process of our cells
Cells Signaling
Giver of the message
Cells signaling
Cells communicate through different types of
signaling mechanisms, depending on the
_________ between the signaling cell and the
__________.
distance, target cell
4 PRIMARY TYPES OF SIGNALING
Autocrine Signaling
Paracrine Signaling
Endocrine Signaling
Juxtacrine Signaling
(Types of Signaling)
a cell produces signaling molecules that bind to receptors on its own surface or receptors within the same cell type.
Autocrine Signaling
This type of signaling is important for self-
regulation, development, and immune system
function.
Autocrine Signaling
The cell targeting its own receptors
Autocrine Signaling
(which type of cell signaling is evident in this scenario?)
A skin cell at the edge of the wound releases growth factors that bind to its own receptors, triggering it to divide and help repair the tissue.
Autocrine Signaling
(Types of cell signaling)
occurs between nearby cells, where signaling molecules diffuse through the extracellular space.
Paracrine Signaling
(Types of Signaling)
plays a critical role in tissue development,
inflammation, and wound healing.
Paracrine Signaling
(Types of Cell Signaling)
Crucial in wound healing
Paracrine Signaling
refers to the general region OUTSIDE of cells
Extracellular Space
(which type of cell signaling is evident in this scenario?)
Nearby skin cells receive those same growth factors, which stimulate neighboring cells to divide and migrate into the wound area. The signal affects only cells close to the source.
Paracrine Signaling
a specific type of material WITHIN that space
Extracellular Matrix
also called as “Nearby Signaling”
Paracrine Signaling
involves the release of hormones into the bloodstream, allowing them to travel long distances to reach target cells.
Endocrine Signaling
Endocrine Signaling is a type of signaling is crucial for maintaining
__________, _________, and ______.
homeostasis, metabolism, and growth.
This type of signaling is important for self-regulation, development, and immune system function.
Endocrine Signaling
(which type of cell signaling is evident in this scenario?)
The pituitary gland in the brain releases hormones like growth hormone into the bloodstream. These hormones travel long distances and reach the injury site to stimulate cell growth and regeneration.
Endocrine Signaling
This type of signaling is mediated by
membrane-bound proteins, gap junctions, or
interactions between cell surface molecules.
Juxtacrine Signaling
In juxtacrine signaling, cells must be in ______ _______ ________ for _________ to occur.
direct physical contact, communication
“Direct Signaling”
Juxtacrine Signaling
Type of signaling wherein it needs to be physically connected with one another
Juxtacrine Signaling
(which type of cell signaling is evident in this scenario?)
Two skin cells in direct contact at the wound edge use membrane-bound proteins to communicate. One cell has a ligand on its surface that binds to a receptor on the adjacent cell, sending signals for healing coordination.
Juxtacrine Signaling
