SUMMARY

• The Soma and Dendrites form a receptor compartment where inputs (synapses) from other neurons are collected to produce all or none axonic responses.

• The dendritic compartment can also receive inputs that operate voltage-gated calcium channels to directly activate all or none action potentials.

• Receptors on dendrites or teledendroglia are both excitatory or inhibitory axonal inputs as well as metabotropic transmitters.
