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. Dendrite are thicker as they are close to the cell body. The space between the terminal boutons and the next cell is known as the synaptic cleft, and is approximately 20 nm thick Hi, in culture of 4-5 DIV you can see the outgrowth of the axon over dendrites. 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. axon branch that travel long distances & communicate with different parts of the nervous system. protein composition of axon membrane is fundamentally different from soma membrane. Is relatively long (some reaching several feet) no rough ER extends from axon, few or no ribosomes. 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.Receive information from other cells at these synapses.May have numerous spines on them to provide a greater surface area for other neurons to synapse on.Are numerous, relatively short, and branch extensively in a tree-like fashion.Transfer information to the cell body and axons.Receive information from other neurons or the external environment.
