Axons in theCNSoften end in fine branches known asterminal arbors(Fig. 2.5C). In most neurons, eachaxon terminalis capped with smallterminal boutons(boutons terminaux,terminal buttons) (Figs. 2.1 and 2.3C, E). These correspond to functional points of contact (synapses) between nerve cells. In...
However, terminal branches of axon arbors at this age give rise to high variable endings. They terminate in finely divided sprays of finger-like extensions and filopodia bearing small spikes rather than the characteristic clusters and strands of crenulated terminals of adult axons. The bases of ...
On the basis of above, it can be assumed that the proteins that ensure the neurotransmitter exoo cytosis are synthesized in the terminal branches of the axon. Following this hypothesis, in the experiments on the neuromuscular preparation of the rat, we first immunohistochemically detected the ...
Our results show for the first time that terminal and preterminal corticospinal axon branches increase in complexity during a protracted early postnatal period. This developmental period extended beyond the early postnatal period of activity-dependent refinement of the topography of terminations. Comparison...
For the spine/dendrite ratio analysis, secondary branches with similar width of apical dendrites of L2–3 pyramidal neurons in the somatosensory cortex were examined. Spine density was calculated by dividing the total spine number by the dendritic branch length. Spine subtypes were classified based on...
21.In vivoimaging of CC axons has revealed both elaboration of branches in supragranular layers and pruning of axon terminal branches between postnatal days 10–14 (P10-14)6,20. Overall, CC axonal arbors reach their mature region- and layer-specific patterns toward the end of the second ...
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...
The downward motion of the lower lip is controlled by the coordinated action of four muscles (DAOM, DLIM, mentalis muscle and platysma muscle) innervated by the facial nerve branches. ACF are preferably caused by the hypoplasia of the DAOM and less commonly the DLIM. Trauma caused injury ...
