Which of the following correctly differentiates the types of muscles based on the type of movement that they produce?
a. smooth is voluntary; skeletal and cardiac are involuntary
b. skeletal is voluntary; smooth and cardiac are involuntary
c. cardiac is voluntary; skeletal and smooth are involuntary
d. smooth, skeletal, and cardiac are all involuntary

The correct answer is B: Skeletal is voluntary, smooth and cardiac are involuntary.

Explanation:

Muscles are of three types: Skeletal muscles which can be moved consciously or voluntarily. Smooth muscles as seen in walls of most of the internal hollow organs. Smooth muscles are seen in the wall or digestive tract and urinary tract which are not in our control. These are involuntary muscles. Cardiac muscle is found in heart which is definitely involuntary as we know that heart contracts and relax rhythmically on its own.

i dont know it at allnow im just getting points at this pint

interphase

the period of cell growth when the cell synthesizes new molecules and organelles. the cell is not dividing and it constitutes the majority of the time spent in the cell cycle

prophase

changes occur in the nucleus and cytoplasm. the chromatin condenses to form structures (sister chromatids) visible with a light microscope and the mitotic spindle begins to form, but the nucleus is still in tact

prometaphase

the nuclear envelope fragments and the spindle microtubules attach to the kinetochores of the sister chromatids

metaphase

all the cell's duplicated chromosomes are lined up at an imaginary plane equidistant between the poles of the mitotic spindle

anaphase

begins when sister chromatids separate from each other and ending when a complete set of daughter chromosomes arrives at each of the two poles of the cell

telophase

the daughter nuclei form at the two poles of a cell

cytokinesis

the division of a cytoplasm to form two separate daughter cells. usually occurs during telophase during mitosis. this and mitosis make up to mitotic (m) phase of the cell cycle
