Term
What is signal transduction?
Definition
is a mechanism that converts a mechanical/chemical stimulus to a cell into a specific cellular response.[1] Signal transduction starts with a signal to a receptor, and ends with a change in cell function.

Term
What 3 places are gap junctions usually found?
Definition
epithelial
smooth
cardiac muscle
nerve
and certain connective tissue
Term
What are gap junctions?
Definition
a specialized intercellular connection between a multitude of animal cell-types.[1][2][3] It directly connects the cytoplasm of two cells, which allows various molecules and ions to pass freely between cells
Term
What type of tissue is composed of closely packed cells of mostly uniform type where cells are also anchored by a basement membrane?
