A glomus jugulare tumor is a tumor of the part of the temporal bone in the skull that involves the middle and inner ear structures. This tumor can affect the ear, upper neck, base of the skull, and the surrounding blood vessels and nerves. A glomus jugulare tumor grows in the temporal bone of the skull, in an area called the jugular foramen.
In mammals, it consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts: [2] The cochlea, dedicated to hearing; converting sound pressure patterns from the outer ear into electrochemical impulses which are passed on to the brain via the auditory nerve.
In 2015 it was found that the petrous bone has remarkably well-preserved DNA. [2] A 2017 study [3] comparing DNA from different skeletal sites concluded that "The inner part of petrous bones and the cementum layer in teeth roots are currently recognized as the best substrates for (ancient DNA) research ... Both substrates display significantly ...
The endocranium in mammals is much reduced in relative size and number of bones compared to the condition in the ancestral land vertebrates, though the occipital bone occur as one or more stout bony elements in several mammal groups. The occipital bone is also found as several bony elements in birds and reptiles, while the skull of modern ...
Structures found at the base of the skull are for example: Bones. There are five bones that make up the base of the skull: ... Frontal bone; Temporal bone; Exobasis ...
The bones were from a large armored plant-eating mammal named Neosclerocalyptus, part of a group called glyptodonts that inhabited the Americas for more than 30 million years before going extinct ...
In all extant and extinct primates, including humans, the auditory bulla is formed by the petrosal bone (the petrous part of the temporal bone). This is a diagnostic trait that can be used to distinguish primates, including anthropoids, tarsiers, lemurs, and lorises, from all other mammals. [3]
