Nettet26. apr. 2024 · The nerve impulse triggers the axon to generate neurotransmitters, which then flow into the synaptic gap. The neurotransmitters diffuse across the gap and then bind to chemical … Nettet16. jun. 2024 · Neurons are specialized cells that are capable of sending electrical as well as chemical signals. Most neurons contain dendrites, which receive these signals, and axons that send signals to other neurons or tissues. There are four main types of neurons: unipolar, bipolar, multipolar, and pseudounipolar neurons.
Nettet7. mar. 2024 · Myelin insulates axons and allows quicker transmission of electrical impulses. A bundle of axons (nerve fibers) in the CNS is called a tract. In the PNS this bundle is called a nerve. Besides from neurons, there are other nervous system cells, for … NettetHowever, although c-Jun is expressed by Schwann cells, a direct functional role of AP-1 transcription factors in regulating PNS myelination remains unclear. 174 Similarly, the transcription factor CREB (which becomes activated through phosphorylation) is found in Schwann cells, and a protein kinase A–dependent increase of CREB phosphorylation …
Nettetperipheral nervous system, ganglia, nerve, autonomic, neuropathy, axonal degeneration, myelinopathy, neuronopathy The peripheral nervous system (PNS) is a uniquely positioned network by which the central nervous system (CNS) commu-nicates with all other organ systems throughout the body. Nerves of the PNS not only carry sensory information …
