A Foot Cramp is an involuntary contraction of muscles in the foot or feet especially the inner arch of the feet, toes and thigh and calf muscles. Pain is usually associated with the contraction of the muscle and even it has subsided one may still encounter aching. Causes of a Foot Cramp ...
Medically, this condition of involuntary muscle contraction is called tetanus. Electricians familiar with this effect of electric shock often refer to an immobilized victim of electric shock as being ”froze on the circuit”. Shock-induced tetanus can only be interrupted by stopping the current throug...
In doing so, the toxin blocks the release of neurotransmitter acetylcholine thus affecting muscle contraction. Within the nervous system, the neurotransmitter is the primary neurotransmitter that sends signals to cells thus contributing to the contraction of the smooth muscle as well as the dilation of...
Methocarbamol is a medication used to relieve muscle spasms, and relax neck and jaw muscle contraction (lockjaw) caused by tetanus, a serious bacterial infection. Common side effects of methocarbamol include slow heart rate (bradycardia), low blood pressure (hypotension), inflammation with blood clots...
This is a bacterium commonly present in the environment. This toxin can cause TMJ muscle spasms. Tetanus is a huge risk factor for lockjaw. When lockjaw is a complication of tetanus, it can take weeks or even months for the condition to clear. Cancer: In some cases, carcinoma removal or ...
Reactogenicity represents the physical manifestation of the inflammatory response to vaccination, and can include injection-site pain, redness, swelling or induration at the injection site, as well as systemic symptoms, such as fever, myalgia, or headach
What are the specific effects of Ca^{2+} in muscle contraction? Why is it necessary for a muscle contraction? Explain why a muscle always works by shortening and cannot actively increase its length unless an external force pulls on it. What effect does increasing the stimulus fr...
To determine the conditions that would produce the maximum tension from any given skeletal muscle fiber, we need to consider several physiological factors that influence muscle contraction. Here’s a step-by-step solution:1. Optimal Len
It is the mechanism by which cells send and receive signals to perform various functions such as regulating body temperature, muscle contraction, or heart rate.Answer and Explanation: Neuronal communication occurs in two ways, electrochemical or electrical and chemi...
Spasms can occur when a muscle is overused and tired, which may result from it being overstretched or being held in the same position for an extended period of time. This causes the muscle cell to run out of energy and fluid, developing a forceful contraction. It can involve part of a ...
