1. Even when a muscle appears to be at rest, a certain amount of sustained contraction is occurring in its fibers. This is called muscle tone. (Muscle tone is a response to nerve impulses that originate repeatedly from the spinal cord and stimulate a few muscle fibers.) A tetanic contraction is when a forceful sustained contraction lacks even partial relaxation.

∙ 13y agoThe strength of summated contractions is always greater than the strength of individual twitches, since twitches are responses to less-frequent stimulations. Summation can culminate in tetanus, a state of sustained maximum contraction. For example, making a fist places the muscles into a state of tetanus.
Another characteristic of muscle function is the ability to achieve muscle tone, or tonus. Tonus is a condition in which a muscle is kept partially contracted over a long period of time. It is produced when one set of fibers, then another set, is briefly stimulated so that some part of the muscle is always contracted, although most of the muscle remains relaxed. Normal posture in the presence of gravity is achieved by tonus. Exercising increases the tonus of muscles used.

What the difference between tetanus and tig?
Tetanus is a disease that affects the muscles and the respiratory system. The difference between tetanus and TIG or tetanus immunoglobulin is that the latter is a form of preventative vaccine for tetanus.
Is there a difference in tonus between dominant and non dominant forearms?
Yes, tonus is another expression of muscle readiness. More dominant forearm mean that it's more ready to do an activity
What are the 4 stages of a muscle cell?
Tonus (relaxation), Excitation (neural stimulation, Clonus (contraction), Tetanus (prolonged contraction), return to Tonus (relaxation) Or Excitation, Excitation-Contraction Coupling, Contraction, Relaxation
What is the Difference between haemophilus b meningococcal conjugate and haemophilus B tetanus toxoid conjugate?
One combines the HIB vaccine with meningococcal vaccine, and the other with tetanus vaccine.
What is the difference between unfused tetanus and fused tetanus?
Unfused tetanus-"the relaxation time between successive twitches will get shorter as the strength of contraction increases in amplitude." On the other hand, Fused tetanus-"Smooth, sustained muscle contraction."
What is tonus?
Tonus is muscular or body tone. Tonus is defined as the continuous contraction of a muscle in the skeleton system which aids in the return of blood to the heart.
What is called a constant muscle contraction?
Tonus is the continous baseline muscle tone in the body.
Does sex influence the tonus in EMG?
Yes
What is tonus also called?
Muscle tone
Where is the center for muscle tonus?
spinal cord
What is the difference between complete tetany and tetanus?
compelete is applying stimuli at a rate that the cell can not relax between subsequent contractios. The max force will allow the cell to freeze, incompete is when the cell can not be compelety relaxed after contraction
What are the indications for anti tetanus vaccine?
The CDC has issued standard recommendations for the anti tetanus vaccine. keep in mind there is a difference between the vaccine (TD) and the immunoglobulin (TIG). If the individual has had 3 or more vaccinations in the past, then you would give the vaccination only if they had not received their last vaccination within the past 10 years (for non tetanus prone wounds) or 5 years (for tetanus prone wounds. he immunoglobulin (TIG) is given only to individuals with tetanus prone wounds who have had less than 3 previous vaccinations (or unknown status). Hope this helps. Shaun Cole
