The axon reflex was discovered by Kovalevskiy and Sokovnin, two Russian scientists in 1873. [5] They described the axon reflex as a new type of peripheral (or local) reflex where electrical signal starts in the middle of the axon and transmit immediately skipping both an integration center and a chemical synapse as typically observed in the spinal cord reflex.
An axo-axonic synapse is a type of synapse, formed by one neuron projecting its axon terminals onto another neuron's axon. [1]Axo-axonic synapses have been found and described more recently than the other more familiar types of synapses, such as axo-dendritic synapses and axo-somatic synapses.
An axon can divide into many branches called telodendria (Greek for 'end of tree'). At the end of each telodendron is an axon terminal (also called a terminal bouton or synaptic bouton, or end-foot). [20] Axon terminals contain synaptic vesicles that store the neurotransmitter for release at the synapse. This makes multiple synaptic connections ...
Flare, a redness in the surrounding area due to arteriolar dilation mediated by axon reflex. [1] [2] [3] Wheal, caused by exudation of extracellular fluid from capillaries and venules. [1] [2] [3] The red spot emerges within 15 seconds. [4] Flare can take up to 45 seconds to begin. [4] Wheal can take up to 3 minutes to begin. [4] [5]
Hanger reflex - reflex of unclear purpose that causes the head to rotate to the right when the top sides of the head are under pressure, named because it can be easily activated with a coat hanger; Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung
A former TD Bank employee based in Florida was arrested and charged with facilitating money laundering to Colombia, New Jersey's attorney general said on Wednesday, in the first such arrest since ...
Substance P is involved in the axon reflex-mediated vasodilation to local heating and wheal and flare reaction. It has been shown that vasodilation to substance P is dependent on the NK1 receptor located on the endothelium.
Skin conditions in dogs are very common, so it's important to recognize the symptoms and understand the factors that cause them. Dr. Rebecca MacMillan, a vet with over 15 years of experience, says ...
