Types of Cell Signaling exam Flashcards

The maintenance of stable internal conditions in an organism.

Local signaling between cells that are in direct contact with each other.

Junctions that connect the cytoplasm of two animal cells, allowing exchange of nutrients and signaling molecules.

Plasmodesmata connect the cytoplasm of plant cells, allowing them to exchange nutrients, materials, and signaling molecules.

When cells make direct contact via membrane proteins, leading to a cellular response.

Distant signaling between cells that are not in direct contact, often using hormones.

Signaling molecules released by a cell or gland that can travel and affect distant cells.

Hormones that travel short distances and act on nearby cells.

Hormones released into the bloodstream, traveling long distances to their target cells.

A type of paracrine signaling where neurotransmitters are released across a synapse to activate a target cell.

Chemicals released by the end of a neuron to transmit a signal or convert it into a cell response.

A small junction between the end of a neuron and another cell.

They allow the exchange of nutrients and signaling molecules between connected cells.

Paracrine signaling acts on nearby cells, while endocrine signaling involves hormones traveling through the bloodstream to distant cells.

A series of events triggered by a receptor that leads to a cellular response.

It involves direct physical contact between the signaling and target cells.

It involves signaling between cells that are not in direct contact, often using hormones.

They transmit signals across the synapse to activate the target cell.

They facilitate the direct exchange of signaling molecules and nutrients between neighboring cells.

The cell that receives the signal and generates a response.

They allow cells to recognize and respond to each other through direct contact.

Gap junctions are found in animal cells, while plasmodesmata are found in plant cells.

To travel through the bloodstream and signal distant target cells.

To signal nearby cells within the vicinity of their synthesis.

It is the junction where neurotransmitters are released to transmit signals to the target cell.

It is crucial for maintaining homeostasis and coordinating cellular activities.

To release signaling molecules that affect the target cell.

To receive neurotransmitters and generate a cellular response.

To facilitate communication between cells to maintain homeostasis and coordinate functions.
