  2. Reflex arc - Wikipedia

    en.wikipedia.org/wiki/Reflex_arc

    Reflex arc demonstrated. When a reflex arc in an animal consists of only one sensory neuron and one motor neuron, it is defined as monosynaptic, referring to the presence of a single chemical synapse. In the case of peripheral muscle reflexes (patellar reflex, achilles reflex), brief stimulation to the muscle spindle results in contraction of ...

    English: Explicative diagram of reflex arc; the journey takes energy and nerve impulse of a stimulus by two or more neurons.The spinal cord(3) receives sensory impulses of the body(2)- here his finger and sent to the central nervous system (afferent pathways(4), which sends impulses to the spinal motor (efferent(5)that sends turn-here the bodies arm muscle through spinal nerves(6).

    In a reflex arc, an action potential never travels to the brain for processing and so results in a much quicker reaction. When a stimulus (pain) is encountered, the signal from that stimulus will travel up the sensory neuron to the spinal column.

  5. Biceps reflex - Wikipedia

    en.wikipedia.org/wiki/Biceps_reflex

    Biceps reflex is a deep tendon reflex (DTR) test (also known as a muscle-stretch reflex test) [1] that examines the function of the C5 reflex arc and the C6 reflex arc. [2] The test is performed by using a tendon hammer to quickly depress the biceps brachii tendon [ 3 ] as it passes through the cubital fossa .

    Hanger reflex - reflex of unclear purpose that causes the head to rotate to the right when the top sides of the head are under pressure, named because it can be easily activated with a coat hanger; Hering–Breuer reflex — is a reflex triggered to prevent over-inflation of the lung

  7. Hiccup - Wikipedia

    en.wikipedia.org/wiki/Hiccup

    The hiccup is an involuntary action involving a reflex arc. [1] Once triggered, the reflex causes a strong contraction of the diaphragm followed about a quarter of a second later by closure of the epiglottis [citation needed], a structure inside of the throat, which results in the "hic" sound. Hiccups may occur individually, or they may occur ...

  8. Somatic nervous system - Wikipedia

    en.wikipedia.org/wiki/Somatic_nervous_system

    A reflex arc is a neural circuit that creates a more or less automatic link between a sensory input and a specific motor output. Reflex circuits vary in complexity—the simplest spinal reflexes are mediated by a two-element chain, of which in the human body there is only one, also called a monosynaptic reflex (there is only one synapse between ...

  9. Golgi tendon reflex - Wikipedia

    en.wikipedia.org/wiki/Golgi_tendon_reflex

    The reflex arc is a negative feedback mechanism preventing too much tension on the muscle and tendon. When the tension is extreme, the inhibition can be so great it overcomes the excitatory effects on the muscle's alpha motoneurons causing the muscle to suddenly relax. [ 1 ]
