axon terminal The ending of an axon which releases neurotransmitters onto a synaptic space near another neurones, muscle cell or gland. Segen's Medical Dictionary. © 2012 Farlex, Inc. All rights reserved. Want to thank TFD for its existence?Tell a friend about us, add a link to this pa...
We examined motor reinnervation accuracy over time in this model under two conditions: 1) when the two terminal nerve branches to either skin (cutaneous) or muscle (quadriceps) were roughly comparable in size, and 2) when the cutaneous branch was larger than the muscle branch. When the ...
We measured the numbers and lengths of nonreconstructed terminal and preterminal branches and the numbers and locations of axon varicosities. We found significant age-dependent increases in all morphologic measures. At 25 days, corticospinal axon branching was sparse, with only a few scattered varico...

Mutations in rpm-1 Alter the Distribution of Synaptic Vesicle Markers C. elegans NMJs are formed en passant between the motor neuron processes and specialized branches of the muscle cells, called muscle arms (53, 54). To visualize the presynaptic terminals of the GABAergic DD and VD motor neu...
2E). Although the large majority of NMJs were innervated at each time point after tSC ablation, the axon terminals displayed a striking feature at 3 weeks not present at 2 weeks: the existence of numerous terminal boutons, or extremely thin branches of axon culminating in a varicosity ...
The part of the neuron that sends information to other neurons ''branches out'' into smaller fibers, which end in bulb-shaped parts known as \\ a. myelin sheaths. b. ion channels. c. dendrite arcs. d. axon terminals. The nucle...
b. terminal ganglia c. spinal cord d. splanchnic nerves. Autonomic Nervous System: The autonomic nervous system is part of the peripheral nervous system. It has two branches that carry out involuntary functions that are complement...
Total branch length was determined by physically tracing the entire NMJ image with a cursor and then adding up the total length of all visible branches. Two or three NMJs were examined from the majority of larvae sampled although some larvae had only one NMJ examined. Electrophysiology Following...
Although the motor axon is wrapped by myelin sheath formed by Schwann cells, the terminal region is only capped by perisynaptic Schwann cells without myelin formation (Fig. 1B). In mammalian muscles, the nerve terminal branches into multiple grape-like varicosities, called synaptic boutons, which...
