They form the lower part of the human back in humans, and the tail end of the back in quadrupeds. In humans, there are five lumbar vertebrae. The term is used to describe the anatomy of humans and ...
Organ replacement in animals. Organ replacement in animals is an emerging field in veterinary science, focusing on improving and prolonging the lives of animals through the replacement or augmentation of damaged or dysfunctional organs. Despite its relative rarity compared to limb prosthesis, strides have been made over the decades, with ...
Dog intelligence or dog cognition is the process in dogs of acquiring information and conceptual skills, and storing them in memory, retrieving, combining and comparing them, and using them in new situations. [1] Studies have shown that dogs display many behaviors associated with intelligence. They have advanced memory skills, and are able to ...
