  2. Neurovascular unit - Wikipedia

    en.wikipedia.org/wiki/Neurovascular_unit

    The neurovascular unit is made up of vascular cells (including endothelium, pericytes, and smooth muscle cells), glia (astrocytes and microglia), and neurons with synaptic junctions for signaling. [1] Cerebral vessels, namely arterioles and the perivascular compartment, form the network of the NVU. [7]

  3. Neuron - Wikipedia

    en.wikipedia.org/wiki/Neuron

    Neurons communicate with other cells via synapses, which are specialized connections that commonly use minute amounts of chemical neurotransmitters to pass the electric signal from the presynaptic neuron to the target cell through the synaptic gap. Neurons are the main components of nervous tissue in all animals except sponges and placozoans.

  4. Synaptic vesicle - Wikipedia

    en.wikipedia.org/wiki/Synaptic_vesicle

    These proteins do not share a characteristic that would make them identifiable as synaptic vesicle proteins, and little is known about how these proteins are specifically deposited into synaptic vesicles. Many but not all of the known synaptic vesicle proteins interact with non-vesicular proteins and are linked to specific functions. [4]

  5. Nerve - Wikipedia

    en.wikipedia.org/wiki/Nerve

    The axons are bundled together into groups called fascicles, and each fascicle is wrapped in a layer of connective tissue called the perineurium. The entire nerve is wrapped in a layer of connective tissue called the epineurium. Nerve cells (often called neurons) are further classified as either sensory or motor.

  6. 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]

  7. Grey matter - Wikipedia

    en.wikipedia.org/wiki/Grey_matter

    Grey matter, or gray matter in American English, is a major component of the central nervous system, consisting of neuronal cell bodies, neuropil (dendrites and unmyelinated axons), glial cells (astrocytes and oligodendrocytes), synapses, and capillaries.

  8. Development of the nervous system - Wikipedia

    en.wikipedia.org/wiki/Development_of_the_nervous...

    The first postmitotic cells must leave the stem cell niche and migrate outward to form the preplate, which is destined to become Cajal–Retzius cells and subplate neurons. These cells do so by somal translocation. Neurons migrating with this mode of locomotion are bipolar and attach the leading edge of the process to the pia.

  9. 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.
