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.
Three types of muscle tissue are cardiac, smooth, and skeletal. Skeletal muscle tissue is the only voluntary muscle, the other two are involuntary.Also, cardiac and skeletal â¦ muscles are striated.   The three main types are skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle has a striped appearance earning its other name striated muscle. It is â¦ designed to work at a moments notice but it tires easily. Smooth muscle is not striped.
