(1) The invaginations were classified into four easily recognized types: regular, chunky, filigree, and ridge (present only in axon hillock regions).
(2) Sequential recordings of spike amplitudes from the axon hillock, soma, and lateral dendrite suggest that the generator of the axotomy-induced component is localized to the normally passive soma and proximal dendrite.
(3) Examination of the synaptic membranes in calyciform endings of the chick ciliary ganglion has shown tight junctions selectively located on axon hillocks of postsynaptic neurons.
(4) A moderate number of axon terminals, which contained spherical clear or pleomorphic vesicles approximately 25-40 nm in diameter, formed symmetric or asymmetric synapses on the soma, the dendrites, the axon hillock, and the initial segment.
(5) The other schools inspected by Ofsted in recent weeks, according to Bore, were: Welford primary in Handsworth (judged as good by Ofsted in 2013), Adderley primary school in Saltley (judged good in January 2012), Alston primary in Bordesley Green East (judged inadequate in 2013, with an emergency inspection in January saying the school was "making reasonable progress towards the removal of special measures"), Golden Hillock in Sparkhill (judged as requiring improvement, in 2013), Gracelands nursery school (deemed good in May 2013), Highfield junior and infant school (which was said to require improvement according to the June 2013 Ofsted), Marlborough junior school in Small Heath ( judged good last June) and Nansen primary (judged satisfactory in 2010).
(6) Satellite cells covering the axon hillock region and initial axon process of the neurons of rat and mouse trigeminal ganglia contained numerous parallel microtubules and microfilaments.
(7) Spine-like processes were observed from the cell soma, axon hillock and the initial segment of the axon.
(8) Isoforms of ankyrin (ankyrinsR) immunologically related to erythrocyte ankyrin (ankyrinRo) are associated with distinct neuronal plasma membrane domains of functional importance, such as cell bodies and dendrites, axonal hillock and initial segments, and nodes of Ranvier.
(9) In layer V the pyramidal cells are of two sizes, medium and large, and both have a typical morphology, although the larger neurons have thicker apical dendrites and better-developed axon hillocks than the medium-sized pyramids.
(10) In contrast, those with smooth axon hillocks accumulated PAS- floccular inclusions, consistent with storage of oligosaccharides.
(11) Neurons whose axons had been crushed and allowed to regenerate exhibited sprouts that arose mainly from the axon hillock and initial segment of the axon.
(12) Axons could be identified by their characteristic morphology; tapering axon hillocks and initial segments, followed by an increase in caliber at the first myelinated segments.
(13) As has now been observed in studies of serotonergic immunohistochemistry and in our own findings on VIP, histamine terminals were observed to lie in close contact with somata and axon hillocks, all of which suggest that axo-somatic connections in molluscs may be more prevalent than previously considered.
(14) Iontophoretic application of TTX inside the axon cap, a distinctive neuropil surrounding the initial segment and the axon hillock and circumscribed by a glial border, and at various positions along the lateral dendrite confirmed the Na+-dependency of the action potentials recorded in normal and axotomized cells and further demonstrated that the soma generates the additional spike component in the latter.
(15) At later post-treatment intervals (15 and 21 days), there were also alterations in the pericellular basket at the Purkinje cell axon hillock, which was poorly developed in or absent from the majority of cells.
(16) The P terminal occasionally surrounds an axon hillock, making symmetric synaptic contacts.
(17) A simple method is presented for selective cell culture of human mesangial cells using explantation of mesangial cell hillocks.
(18) The other allegation – that Alam and Park View's governing trust has taken over nearby schools – is also dismissed by Alam, who says that it was the DfE that asked Park View to take over two struggling schools: Golden Hillock secondary and Nansen primary, which is right next door.
(19) A few synaptic boutons were found on the surface of the axon hillock.
(20) The results that the cell membrane of axon hillock and proximal stem regions of many sensory large and small neurons may have numerous sodium channels and could affect signal propagation.
Hummock
Definition:
(n.) A rounded knoll or hillock; a rise of ground of no great extent, above a level surface.
(n.) A ridge or pile of ice on an ice field.
(n.) Timbered land. See Hammock.
Example Sentences:
(1) He wondered what had happened to the land, its fish-filled inlets, the shrimp-spawning marsh, the oak groves, the hummocks overrun with white egrets, how a place that fed so richly whoever sailed through it could dissolve, history and graveyard and church and road and home.
(2) Reaching an open area of sparse trees beside the track, we set off across a large clearing of soft hummocks.
(3) Highest densities were located on the sloping banks of hummocks, ponds and potholes.
