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 ...
Basic ways that neurons can interact with each other when converting input to output. 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 ...
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.
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.

An 18-year-old was arrested in connection to the fatal shooting of a man last month who was reportedly trying to sell his PlayStation 5. On Nov. 24, officers with the Houston Police Department ...
A preliminary investigation by homicide detectives found Mina lived at the location with her boyfriend, Sanchez, and the victim's two children: an 8-month-old infant and a 2-year-old boy.
The Seattle Seahawks are resetting again in 2025, though not at the scale they did the previous year.. The team fired offensive coordinator Ryan Grubb on Monday after just one season, coach Mike ...
A fasciculation, or muscle twitch, is a spontaneous, involuntary muscle contraction and relaxation, involving fine muscle fibers. [1] They are common, with as many as 70% of people experiencing them. [1] They can be benign, or associated with more serious conditions. [1]
