The synapse is shown enlarged in the inset. In neuromuscular junctions, axons synapse directly on muscles. These help with the conduction of action potentials.Īxoaxonal: Axon is connected to another neuron’s axon Īxodendritic: Axon is connected to another neuron’s dendritesĪxosomatic: Axon is connected directly to another neuron’s soma There are openings between the Schwann cells called Nodes of Ranvier. Myelin acts as insulator to help conduction of action potential. Most are myelinated, i.e., have myelin sheaths that are made by Schwann cells or oligodendrocytes. The space between the terminal boutons and the next cell is known as the synaptic cleft, and is approximately 20 nm thick These swellings at the terminal bouton is where the neuron synapses with another neuron Ĭontains numerous vesicles which hold neurotransmitter Has terminal boutons at the end where the synapse is located. Is relatively long (some reaching several feet) The connection between dendrites that synapse on other dendrites is called dendrodendritic.īegins at the axon hillock, which is a swelling at the junction of the axon and soma where there are many Na + channels and the action potential starts.The connection between axons that synapse on dendrites is called axodendritic.This section will briefly describe why cell types are important. Receive information from other cells at these synapses. You will learn and recognize the key morphological differences between axons and dendrites.May have numerous spines on them to provide a greater surface area for other neurons to synapse on. ![]()
