                    cranial and dorsal borders that characterize the hearts of most small rodents such as the rat. Note that because of obliquity the vertebral
                    bodies have been projected on the upper part of the lung, creating the misimpression of an abnormally tall heart (also termed increased
                    apicobasilar dimension).
