Meanwhile, terrestrial box turtles, which are illegal to breed or keep as pets in more than 20 states, have a potential lifespan of up to 100 years, and an average longevity of 40 to 50 years in captivity. Several decades ago, however, that long lifespan expectation for pet turtles wasnât necessarily the case. In Mitchellâs estimation, many turtles back then likely lived just 4 to 6 years in captivity due to improper care. Now, as our understanding of how to properly care for turtles has grown, we are seeing those decades-long lifespans that make pet turtles such a commitment.
fundus of uterus. Type:Term. Definitions. 1. the upper rounded extremity of the uterus above the openings of the uterine tubes.
The walls of the body are much thicker than those of the cervix as they provide for the protection and support of the developing fetus and contain the muscles that propel the fetus out of the motherâs body during childbirth. Superior to the body is a domed region known as the fundus of the uterus. The fallopian tubes extend laterally from the corners of the fundus. Three distinct tissue layers make up the walls of the uterus: The perimetrium is the outermost layer that forms the external skin of the uterus. It is a serous membrane continuous with the peritoneum that covers the major organs of the abdominopelvic cavity.
