A prolongation or process extending from a nerve cell, e.g. an axon or dendrite. The portion of the plasma membrane surrounding a dendritic spine. Protrusion from a dendrite. Spines are specialised subcellular compartments involved in the synaptic transmission. They are linked to the dendritic shaft by a restriction. Because of their bulb shape, they function as a biochemical and an electrical compartment. Spine remodeling is though to be involved in synaptic plasticity. Any constituent part of a cell, the basic structural and functional unit of all organisms. A prolongation or process extending from a cell, e.g. a flagellum or axon. Any constituent part of a cell projection, a prolongation or process extending from a cell, e.g. a flagellum or axon. A small membranous protrusion, often ending in a bulbous head and attached to the neuron by a narrow stalk or neck. A neuron projection that has a short, tapering, often branched, morphology, receives and integrates signals from other neurons or from sensory stimuli, and conducts a nerve impulse towards the axon or the cell body. In most neurons, the impulse is conveyed from dendrites to axon via the cell body, but in some types of unipolar neuron, the impulse does not travel via the cell body.
