(IEMR1)Overview of the Endocrine System

Question 1

What are the three major systems of intercellular communication?(3 points)

Answer 1

nervous system, endocrine system and immune system

Question 2

What is autocrine communication?

Answer 2

autocrine signaling is a form of cell signaling in which a cell secretes a hormone or chemical messenger (called the autocrine agent) that binds to autocrine receptors on that same cell, leading to changes in the cell.

Question 3

This type of signaling is a form of cell-cell communication in which a cell produces a signal to induce changes in nearby cells, altering the behavior or differentiation of those cells.

Answer 3

paracrine

Question 4

These are endogenous chemicals that transmit signals across a synapse from one neuron (brain cell) to another ‘target’ neuron.

Answer 4

neurotransmitters

Question 5

What is the cell description: are cells that receive neuronal input (neurotransmitters released by nerve cells or neurosecretory cells) and, as a consequence of this input, release message molecules (hormones) to the blood.

Answer 5

neuroendocrine cell
