Parametal cells
WebSpiny stellate cells received their name from their star-shaped appearance and the presence of a large number of spines on their dendrites. Although spiny stellate cells and pyramidal cells are both glutamatergic cells, the two cell types in layer IV of the cortex greatly differ in their morphology. First, spiny stellate cells do not have ...

Webpyramidal cells: neurons of the cerebral cortex that, in sections perpendicular to the cortical surface, exhibit a triangular shape with a long apical dendrite directed toward the surface of the cortex; there are also lateral dendrites, and a basal axon that descends to deeper layers. WebMay 2, 2014 · In pyramidal cells, there is an abundance of Na+, Ca2+, and K+ channels in the dendrites, and some channels in the soma. Ion channels within pyramidal cell dendrites have different properties from the same ion channel type within the pyramidal cell soma. Voltage-gated Ca2+ channels in pyramidal cell dendrites are activated by subthreshold …
WebPyramidal cells are named as such because their cell body resembles the shape of a teardrop or a rounded pyramid. Of note, dendrites of hippocampal pyramidal cells extend from both the apex (i.e., apical dendrites) and the base of the cell body (i.e., basal dendrites), and connect with other pyramidal cells for a dense array of neural ...

Each of these tracts carry efferent signals to either the spinal cord … WebPyramidal cells have large, pyramid-shaped cell bodies that range from 20–120 µm in diameter. They are excitatory neurons that have numerous apical and basal dendrites …
WebIn geometry, the 5-cell is the convex 4-polytope with Schläfli symbol {3,3,3}. It is a 5-vertex four-dimensional object bounded by five tetrahedral cells. It is also known as a C 5, pentachoron, pentatope, pentahedroid, or tetrahedral pyramid.It is the 4-simplex (Coxeter's polytope), the simplest possible convex 4-polytope, and is analogous to the tetrahedron …
