What is a Non-dihydropyridine calcium channel blockers?
Diltiazem and verapamilBoth act centrally at heart muscle contraction
What does curare act by in the neuromuscular junction?
Curare acts by blocking nicotinic acetylcholine receptors at the neuromuscular junction, preventing the binding of acetylcholine to these receptors. This leads to muscle paralysis since acetylcholine is unable to initiate muscle contraction.
What is Generalisability?
act of generalizing; general statement or conclusion; (Psychology) act of reacting to a new stimulus as to a similar stimulus
What structure is found in cardiac muscle tissue but not skeletal muscle tissue?
Intercalated discs are unique to cardiac muscle tissue, providing a strong connection between adjacent cells and allowing for coordinated contraction of the heart. Skeletal muscle tissue lacks intercalated discs since individual muscle fibers act independently.
What is the term that describes the muscles ability to maintain a slight contraction keeping the muscle firm?
Synergy is the term for the ability of muscles to be slightly contracted at all times to be ready to act. Most of the muscles are usually in this form.
Why muscle contraction doest not occur below threshold stimulus?
Muscle contraction does not occur below the threshold stimulus because the stimulus is not strong enough to trigger an action potential in the muscle fiber. Without reaching the threshold stimulus, the depolarization of the muscle cell membrane is not significant enough to initiate the series of events leading to muscle contraction.
To which part of the mind does a suggestion act as a stimulus?
Emotion
Is the stimulus bill the same as the American Recovery and Reinvestment Act of 2009?
yes the American recovery and reinvestment act (ARRA) is the same thing as the stimulus package. the (ARRA) is the real name.
What movements act on the food from the time it leaves the mouth to the time it is digested?
Peristaltic movement of the muscle propels the food ingested further in the digestive system. This movement occurs by rhythmic contraction and relaxation of the muscles.
Do muscle act on surrounding fat?
no muscle not act on surrounding fat. muscle act on moving. fat accquired from laziness. laziness=muscle not acting. Studies have shown that muscle do in fact act upon its surrounding fat. Muscle that has been developed allow a 12% increase for the surrounding fat to become muscle! Muscle act as an inner furnace for your body and burns your fat as well throughout the day! That's why people with more muscle need to eat more often.
What is the contraction of the word comrade?
