Cells (Interaction and interdependence)

Cells interact by sending and receiving signals. This group covers neural signalling: resting and action potentials, the speed of nerve impulses and the synapses that link neurons to each other and to effector cells.

Subtopics

Work through them in order. Each one has notes, exam questions and flashcards, and a PDF of each.
