What is gross anatomy - answer ...branch of anatomy that deals with
the structure of organs and tissues that are visible to the naked eye.
Define embryology, cytology & microscopic anatomy -
answer ...Embryology- development before birth, Cytology- cells of the
body, Microscopic Anatomy- structures to small to be seen with naked
eye
The main component of the cytoplasm - answer ...Cytosol
What is mitosis - answer ...cell division that results in two daughter cells
each having the same # and kind of chromosomes as the parent
nucleus, typical of ordinary tissue growth.
Role of leptin in the body - answer ...Leptin regulates energy intake and
fat stores so that weight is maintained within a relatively narrow range.
"Leptin is a hormone made by fat cells, that decrease appetite"
