Hindu concept of 'Muscle contraction'
Hinduism views muscle contraction as a vital process, influenced by stimuli and potentially aided by calcium. It is linked to bodily functions, treatments like Arthrothermia, and may be induced through practices like Pranayama.

(1) Muscle contraction is one of the parameters used in assessing muscle power, and it is graded based on the ability of the muscle to contract against gravity and resistance.[1] (2) This is a process that Yavakshara regulates, and it decreases obstructive symptoms, which helps in the treatment.[2] (3) This is a function of vascular tone, which is essential for regulating blood pressure and maintaining proper blood flow, and is a part of the mechanisms that control blood pressure.[3] (4) Muscle contraction is one of the essential functions of the human body that salt plays a role in, and it is absolutely essential for animal life, but can be harmful to animals and plants in excess.[4] (5) Muscle contractions, specifically peristalsis, are waves of muscle contractions that propel food through the esophagus, and are controlled by the esophagus's nervous system.[5]

(1) This process is caused by praziquantel, which increases calcium levels in the muscle cells of parasites, leading to their paralysis and death.[6]

(1) Muscle contraction is a pathology in the development of TTH, and it is a key aspect of the bodily tension associated with the condition, as mentioned in the text.[7]
The concept of Muscle contraction in scientific sources
Muscle contraction is a complex physiological process where muscles shorten and generate force. It involves calcium ions, contractile proteins, and is crucial for various bodily functions. This includes movement, breathing, and is influenced by factors like exercise, pain, and neurological conditions.

(1) This refers to the time, which was 2-3 times longer in red than in white muscles, again varying directly with the fractional blood flow.[8] (2) These are not caused by a constantly flowing direct current at therapeutic amperages, which was a previous assumption regarding its usefulness in the treatment of paralyses, but experimental studies have since proven its beneficial effects.[9] (3) Muscle contraction is the action of the pelvic floor muscles, and the patient's ability to time and control these contractions is evaluated during the assessment process.[10] (4) This refers to the action of a muscle, and the ability to obtain a contraction against resistance was assessed.[11] (5) This is the process where muscles tighten, and it can affect the accuracy of ankle size measurements. Measurements should be done with the foot in a relaxed position so that no muscle contraction would occur.[12]

(1) Muscle contraction is a key element in the examination, where the examiner palpates the muscle to detect any activity or movement, which helps determine the muscle's strength and function, which is an important step.[13] (2) This is detected by placing a finger over the tendon if the reflex is not visible, and it is related to the deep tendon reflexes.[14] (3) Muscle contraction is the process by which muscles generate force, and repetitive muscle contractions during cycling were suggested to impose substantial force on bones.[15] (4) This is the process by which muscles generate force and shorten, which is triggered by an action potential and involves the interaction of actin and myosin.[16] (5) Troponins control the interaction of calcium-mediated actin and myosin for this process, and they are regulatory protein complexes located on the thin filaments of striated muscles.[17]

(1) Muscle contraction is affected by exercise-induced hyponatraemia, and the central role of sodium in this process is crucial, while the Na+/K+-pump is responsible for the adequate concentration of Ca2+ in the sarcoplasmic reticulum of muscle cells.[18] (2) This is the process of a muscle becoming shorter or tighter, and the inhibition of muscle contraction is one of the physical impairments in those affected by rheumatoid arthritis.[19] (3) This effect after ejaculation results in a refractory period whereby immediate restimulation does not result in subsequent vasodilation and arterial filling.[20] (4) Sustained muscle contraction and shortening of sarcomeres lead to local ischaemia and release of several pro-inflammatory chemical mediators that may sensitise peripheral nociceptors, and active MTrPs may develop after an injury to muscle fibres, which may be a single traumatic event or repetitive micro-trauma to muscles, which then is followed by it.[21]

(1) Therapeutic resistance exercises cause this, microscopic damage, and repair, increasing muscle power and endurance.[22]
From: Onderstepoort Journal of Veterinary Research
(1) The coordination of muscle contraction is a significant function of the neural networks in the oviduct, specifically in relation to the transportation of an egg.[23]
From: International Journal of Pharmacology
(1) A solution high in K + induces this by opening the voltage dependent Ca 2+ channels.[24]
From: South African Journal of Psychiatry
(1) These are the tightening of muscles, and chronic dystonia is characterized by persistent and involuntary ones that result in abnormal movements or sustained postures.[25]
From: International Journal of Pharmacology
(1) The shortening of muscle fibers, which can be delayed after nerve regeneration if the nerve repair is significantly delayed, potentially leading to irreversible muscle changes.[26]
