  2. End-plate potential - Wikipedia

    en.wikipedia.org/wiki/End-plate_potential

    Signal transmission from nerve to muscle at the motor end plate. The neuromuscular junction is the synapse that is formed between an alpha motor neuron (α-MN) and the skeletal muscle fiber. In order for a muscle to contract, an action potential is first propagated down a nerve until it reaches the axon terminal of the motor neuron.

    Hyperfixations — on specific activities, interests and, yes, meals — are a common experience among people with ADHD. They may also hyperfocus on a particular topic, Adler says.

  4. Neuromuscular junction - Wikipedia

    en.wikipedia.org/wiki/Neuromuscular_junction

    A neuromuscular junction (or myoneural junction) is a chemical synapse between a motor neuron and a muscle fiber. [1] It allows the motor neuron to transmit a signal to the muscle fiber, causing muscle contraction. [2] Muscles require innervation to function—and even just to maintain muscle tone, avoiding atrophy.

  5. Association fiber - Wikipedia

    en.wikipedia.org/wiki/Association_fiber

    Association fibers are axons (nerve fibers) that connect cortical areas within the same cerebral hemisphere. [ 1 ] In human neuroanatomy, axons within the brain, can be categorized on the basis of their course and connections as association fibers, projection fibers , and commissural fibers . [ 1 ]

  6. Muscle cell - Wikipedia

    en.wikipedia.org/wiki/Muscle_cell

    Diagram of skeletal muscle fiber structure. Skeletal muscle cells are the individual contractile cells within a muscle and are more usually known as muscle fibers because of their longer threadlike appearance. [10] Broadly there are two types of muscle fiber performing in muscle contraction, either as slow twitch or fast twitch .

  7. Gamma motor neuron - Wikipedia

    en.wikipedia.org/wiki/Gamma_motor_neuron

    Both of these fiber types are part of the intrafusal muscle spindle fibers, where the static gamma motor neurons innervate onto. Nuclear chain fibers' nuclei are organized in longitudinal columns, which is where it gets its name from, whereas the nuclear bag fibers' nuclei are clumped in the midsection of the muscle spindle.

  8. Development of the nervous system in humans - Wikipedia

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

    The development of the nervous system in humans, or neural development, or neurodevelopment involves the studies of embryology, developmental biology, and neuroscience.These describe the cellular and molecular mechanisms by which the complex nervous system forms in humans, develops during prenatal development, and continues to develop postnatally.

    Scrolling on social media is also a way to "disassociate" and give the brain a rest after a long day, Bobinet said. This is an "avoidance behavior," which the habenula controls.
