Fermium is a synthetic chemical element; it has symbol Fm and atomic number 100. It is an actinide and the heaviest element that can be formed by neutron bombardment of lighter elements, and hence the last element that can be prepared in macroscopic quantities, although pure fermium metal has not been prepared yet.

Parts-per-million cube of relative abundance by mass of elements in an average adult human body down to 1 ppm. About 99% of the mass of the human body is made up of six elements: oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus. Only about 0.85% is composed of another five elements: potassium, sulfur, sodium, chlorine, and magnesium ...

Similar balance receptors called statocysts can be found in many invertebrate groups but are not contained in the structure of an inner ear. Mollusk statocysts are of a similar morphology to the displacement -sensitive organs of vertebrates; [ 5 ] however, the function of the mollusk statocyst is restricted to gravity detection and possibly ...
In humans, it is a small tubercle on the visible part of the ear, the auricle. The antitragus is located just above the earlobe and points anteriorly. It is separated from the tragus by the intertragic notch. The antitragicus muscle, an intrinsic muscle of the ear, arises from the outer part of the antitragus. [1] [2]
In 2020, doctors found a Japanese beetle inside the ear of a 14-year-old girl in Pennsylvania. She had been swimming in a pool, then detected a crawling sensation in her right ear.
The ear canal (external acoustic meatus, external auditory meatus, EAM) is a pathway running from the outer ear to the middle ear.The adult human ear canal extends from the auricle to the eardrum and is about 2.5 centimetres (1 in) in length and 0.7 centimetres (0.3 in) in diameter.
