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 ...
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]
Latent period (epidemiology), the time interval between when an individual is infected by a pathogen and when he or she becomes capable of infecting other susceptible individuals. Muscle contraction, the time between a stimulus to the nerve and the contraction of the muscle; Virus latency, a period during which a virus remains dormant in a cell ...
The rate of muscle twitch contractions and relaxations are thermally dependent (Q 10 of 2.0-2.5), whereas maximum contraction, e.g., tetanic contraction, is thermally independent. [6] Muscles of some ectothermic species. e.g., sharks, show less thermal dependence at lower temperatures than endothermic species [4] [7]
This is now known as the Trousseau sign of latent tetany. [8] 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]
“The proportion of slow-twitch to fast-twitch muscle fibers in a particular muscle varies depending on the function of the muscle and the type of training in which an individual participates.
Donald Trump is condemning the alleged actions of Luigi Mangione and the people who defend him.. In a Dec. 17 news conference, the president-elect, 78, denounced the man accused of killing ...
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]
