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 uterus varies considerably in size, shape and weight depending on the status of parturition and estrogenic stimulation. The uterus is a fibromuscular organ that can be divided into the upper muscular uterine corpus and the lower fibrous cervix, which extends into the vagina. The upper part of the uterus above the insertion of the fallopian tubes is called the fundus. The narrow portion situated between corpus and cervix is known as the isthmus and lies approximately at the level of the course of the uterine artery and the internal os of the cervix.
