What are some examples of organs and tissues where mitosis is more frequent, less frequent or practically absent?

Generally in vertebrates mitosis is more frequent in a tissue that needs intense renewing due to their functions, like epithelial tissues and the bone marrow. In plants the meristem tissue has numerous cells undergoing mitosis.

Mitosis take place with low frequency in tissues of slow renovation, like the bones in adults and the connective tissues.

In some adult tissues mitosis is almost absent, like the nervous tissue and the striated muscle tissue (skeletal and cardiac). The nervous tissue develops from stimulus by development of new electrical networks among cells and the striated muscle tissue grows by cellular hypertrophy.
