In normal individuals, there is a constant production of ketone bodies by the liver and their utilization by extrahepatic tissues. The concentration of ketone bodies in blood is maintained around 1 mg/dl. Their excretion in urine is very low and undetectable by routine urine tests (Rothera's test).
A: Examples of involuntary muscles, also known as smooth muscles, are the muscles of the urogenital tract, digestive tract, circulatory system and respiratory tract. Involuntary muscles are not controlled by the organism's will. Their actions are automatic and facilitated by the autonomic nervous system.
a voluntary muscle is a muscle that move when you tell it to Muscles in our hands (skeletal muscle) are called voluntary, because these muscles act according to the impulses (â¦ orders) given by our conscious brain. Heart (cardiac muscle) is an example of an involuntary muscle.It works all the time with impulses from our brain stem, which is involuntary. Some more examples of voluntary muscles in our body are muscles of the chest, neck, abdomen, and legs. Involuntary muscles include the muscles of the digestive system.--- Skeletal muscles, like biceps (the muscles that flex your forearm/wrist toward your shoulder) are voluntary muscles.These muscles will not flex unless you think about flexing them, and your brain sends that signal to your arm.nvoluntary muscles include the muscles of the digestive system. --- Skeletal muscles, like biceps (the muscles that flex your forearm/wrist toward your shoulder) are voluntary muscles.
