  2. Neuron - Wikipedia

    en.wikipedia.org/wiki/Neuron

    A neuron, neurone, [1] or nerve cell is an excitable cell that fires electric signals called action potentials across a neural network in the nervous system.They are located in the brain and spinal cord and help to receive and conduct impulses.

  3. Nerve - Wikipedia

    en.wikipedia.org/wiki/Nerve

    A nerve is an enclosed, cable-like bundle of nerve fibers (called axons) in the peripheral nervous system. Nerves have historically been considered the basic units of the peripheral nervous system. Nerves have historically been considered the basic units of the peripheral nervous system.

  4. Nervous system - Wikipedia

    en.wikipedia.org/wiki/Nervous_system

    The nervous system is defined by the presence of a special type of cell—the neuron (sometimes called "neurone" or "nerve cell"). [5]

  5. Brain cell - Wikipedia

    en.wikipedia.org/wiki/Brain_cell

    Brain cells make up the functional tissue of the brain. The rest of the brain tissue is the structural stroma that includes connective tissue such as the meninges, blood vessels, and ducts. The two main types of cells in the brain are neurons, also known as nerve cells, and glial cells, also known as neuroglia. [1]

  6. Synapse - Wikipedia

    en.wikipedia.org/wiki/Synapse

    In the nervous system, a synapse [1] is a structure that allows a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or a target effector cell. Synapses can be classified as either chemical or electrical, depending on the mechanism of signal transmission between neurons.

  7. Nervous tissue - Wikipedia

    en.wikipedia.org/wiki/Nervous_tissue

    It is composed of neurons, also known as nerve cells, which receive and transmit impulses to and from it , and neuroglia, also known as glial cells or glia, which assist the propagation of the nerve impulse as well as provide nutrients to the neurons. [1] Nervous tissue is made up of different types of neurons, all of which have an axon.

  8. Cellular neuroscience - Wikipedia

    en.wikipedia.org/wiki/Cellular_neuroscience

    In a synapse, the neuron that sends the signal is the presynaptic neuron and the target cell receives that signal is the postsynaptic neuron or cell. Synapses can be either electrical or chemical. Electrical synapses are characterized by the formation of gap junctions that allow ions and other organic compound to instantaneously pass from one ...

  9. Ganglion - Wikipedia

    en.wikipedia.org/wiki/Ganglion

    A pseudoganglion is a localized thickening of the main part or trunk of a nerve that has the appearance of a ganglion [2] but has only nerve fibers and no nerve cell bodies. Pseudoganglia are found in the teres minor muscle [3] and radial nerve. [citation needed]
