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 human uterus is a pear-shaped organ composed of two distinct anatomic regions: the cervix and the corpus. The corpus is further divided into the lower uterine segment and the fundus. The cervix is a narrow cylindrical passage which connects at its lower end with the vagina. At its upper end, the cervix widens to form the lower uterine segment (isthmus); the lower uterine segment in turn widens into the uterine fundus.
