IB Biology Topic C2.2.5 Synapses as Junctions Between Neurons and Between Neurons and Effector Cells Revision Notes (SL/HL) | RevisionDojo

Written by official IB examiners

A synapse is a junction where one neuron passes a signal to another neuron or to an effector cell

Definition

Synapse

A chemical synapse is the point where two neurons meet or where a neuron meets an effector cell.

A synapse is a junction where a neuron connects with another neuron or with an effector cell such as a muscle fibre or gland cell.
The neuron before the junction is the presynaptic neuron, and the cell after it carries the postsynaptic membrane.
A narrow gap called the synaptic cleft separates the two cells, so the electrical signal cannot cross directly.

The presynaptic neuron releases a chemical neurotransmitter that diffuses across the cleft, a process covered in detail in C2.2.6.
