  2. Tetanic contraction - Wikipedia

    en.wikipedia.org/wiki/Tetanic_contraction

    Fused tetanus is when there is no relaxation of the muscle fibers between stimuli and it occurs during a high rate of stimulation. [5] A fused tetanic contraction is the strongest single-unit twitch in contraction. [6] When tetanized, the contracting tension in the muscle remains constant in a steady state. This is the maximal possible ...

  3. Summation (neurophysiology) - Wikipedia

    en.wikipedia.org/wiki/Summation_(neurophysiology)

    Summation, which includes both spatial summation and temporal summation, is the process that determines whether or not an action potential will be generated by the combined effects of excitatory and inhibitory signals, both from multiple simultaneous inputs (spatial summation), and from repeated inputs (temporal summation).

  4. Tetany - Wikipedia

    en.wikipedia.org/wiki/Tetany

    Also, tetany can be demonstrated by tapping anterior to the ear, at the emergence of the facial nerve. A resultant twitch of the nose or lips suggests low calcium levels. This is now known as the Chvostek sign. [citation needed] EMG studies reveal single or often grouped motor unit discharges at low discharge frequency during tetany episodes.

  5. Neuromuscular junction - Wikipedia

    en.wikipedia.org/wiki/Neuromuscular_junction

    Tetanus toxin, also known as tetanospasmin is a potent neurotoxin produced by Clostridium tetani and causes the disease state, tetanus. The LD 50 of this toxin has been measured to be approximately 1 ng/kg, making it second only to botulinum toxin D as the deadliest toxin in the world. It functions very similarly to botulinum neurotoxin by ...

  6. Muscle contraction - Wikipedia

    en.wikipedia.org/wiki/Muscle_contraction

    Depiction of smooth muscle contraction. Muscle contraction is the activation of tension-generating sites within muscle cells. [1] [2] In physiology, muscle contraction does not necessarily mean muscle shortening because muscle tension can be produced without changes in muscle length, such as when holding something heavy in the same position. [1]
