  2. Histamine H2 receptor - Wikipedia

    en.wikipedia.org/wiki/Histamine_H2_receptor

    Smooth muscle relaxation (Experimental histamine H 2 receptor agonist used for asthma and COPD) Inhibit antibody synthesis, T-cell proliferation and cytokine production; Vasodilation – PKA activity causes phosphorylation of MLCK, decreasing its activity, resulting in MLC of myosin being dephosphorylated by MLCP and thus inhibiting contraction ...

  3. Histamine agonist - Wikipedia

    en.wikipedia.org/wiki/Histamine_agonist

    A histamine agonist is a drug which causes increased activity at one or more of the four histamine receptor subtypes. H 1 agonists promote wakefulness. [1] H 2: Betazole and Impromidine are examples of agonists used in diagnostics to increase histamine. H 3: Betahistine is a weak Histamine 1 agonist and a very strong antagonist of the Histamine ...

    Agonist muscles are also called prime movers since they produce most of the force, and control of an action. [6] Agonists cause a movement to occur through their own activation. [7] For example, the triceps brachii contracts, producing a shortening (concentric) contraction, during the up phase of a push-up (elbow extension).

  6. Abductor digiti minimi muscle of the hand - Wikipedia

    en.wikipedia.org/wiki/Abductor_digiti_minimi...

    In human anatomy, the abductor digiti minimi (abductor minimi digiti, abductor digiti quinti, ADM) is a skeletal muscle situated on the ulnar border of the palm of the hand. It forms the ulnar border of the palm and its spindle-like shape defines the hypothenar eminence of the palm together with the skin, connective tissue, and fat surrounding it.

  7. Extensor digitorum longus muscle - Wikipedia

    en.wikipedia.org/wiki/Extensor_digitorum_longus...

    This muscle varies considerably in the modes of origin and the arrangement of its various tendons. The tendons to the second and fifth toes may be found doubled, or extra slips are given off from one or more tendons to their corresponding metatarsal bones, or to the short extensor, or to one of the interosseous muscles.

  8. Extrafusal muscle fiber - Wikipedia

    en.wikipedia.org/wiki/Extrafusal_muscle_fiber

    Extrafusal muscle fibers are the standard skeletal muscle fibers that are innervated by alpha motor neurons and generate tension by contracting, thereby allowing for skeletal movement. They make up the large mass of skeletal striated muscle tissue and are attached to bone by fibrous tissue extensions ( tendons ).

  9. Proprioception and motor control - Wikipedia

    en.wikipedia.org/wiki/Proprioception_and_Motor...

    The Golgi tendon organ (GTO) is a proprioceptive organ that lies at the muscle-tendon junction. GTOs relay information through group Ib afferents, and encode active muscle force. As they are connected at one end to motor units, individual GTOs only relay information on a few fibers.
