The extensive dendritic tree of two hippocampal pyramidal neurons (magenta) with all incoming synapses genetically labeled (green spots). [2] Dendrites are one of two types of cytoplasmic processes that extrude from the cell body of a neuron, the other type being an axon. Axons can be distinguished from dendrites by several features including ...
A reconstruction of a pyramidal cell. Soma and dendrites are labeled in red, axon arbor in blue. (1) Soma, (2) Basal dendrite, (3) Apical dendrite, (4) Axon, (5) Collateral axon. One of the main structural features of the pyramidal neuron is the conic shaped soma, or cell body, after which the neuron is named.
A dendritic spine (or spine) is a small membrane protrusion from a neuron's dendrite that typically receives input from a single axon at the synapse.Dendritic spines serve as a storage site for synaptic strength and help transmit electrical signals to the neuron's cell body.
A multipolar neuron is a type of neuron that possesses a single axon and many dendrites (and dendritic branches), allowing for the integration of a great deal of information from other neurons. These processes are projections from the neuron cell body .
The cells in nervous tissue are densely packed and little information on their structures and interconnections can be obtained if all the cells are stained. Furthermore, the thin filamentary extensions of neural cells, including the axon and the dendrites of neurons, are too slender and transparent to be seen with normal staining techniques ...
An apical dendrite is a dendrite that emerges ... which are transparent in early stages of larval development and allow for dye-labeled neurons to be repeatedly ...
Most synapses connect axons to dendrites, [8] [9] but there are also other types of connections, including axon-to-cell-body, [10] [11] axon-to-axon, [10] [11] and dendrite-to-dendrite. [9] Synapses are generally too small to be recognizable using a light microscope except as points where the membranes of two cells appear to touch, but their ...
A dendrite is a branching projection of the cytoplasm of a cell. While the term is most commonly used to refer to the branching projections of neurons, it can also be used to refer to features of other types of cells that, while having a similar appearance, are actually quite distinct structures. [1] Non-neuronal cells that have dendrites:
