Question

Quizplus · Accepted Answer

The most common method of communication between cells in animal bodies is by secreting chemical messengers that attach to target cells. These chemical messengers can be hormones or neurotransmitters and they travel through the bloodstream or interstitial fluid to reach their target cells. Direct connections between the cytoplasm of neighboring cells (known as gap junctions) are also a method of communication but are less common than chemical signaling. The use of ions to create current flow through the interstitial fluid and producing cell extensions that reach to other cells in order to touch them and pass the message are not common methods of communication between cells in animal bodies.
