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. [5]
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 ...
Older set of terminology shown in Parts of the Human Body: Posterior and Anterior View from the 1933 edition of Sir Henry Morris' Human Anatomy. Many of these terms are medical latin terms that have fallen into disuse. Front: Frons - forehead; Facies - face; Pectus - breast; Latus - flank; Coxa - hip; Genu - knee; Pes - foot; Back: Vertex ...
Trace metals within the human body include iron, lithium, zinc, copper, chromium, nickel, cobalt, vanadium, molybdenum, manganese and others. [ 1 ] [ 2 ] [ 3 ] Some of the trace metals are needed by living organisms to function properly and are depleted through the expenditure of energy by various metabolic processes of living organisms.
The body is made up of approximate 1.5% calcium and this abundance is reflected in its lack of redox toxicity and its participation in the structure stability of membranes and other biomolecules. [6] Calcium plays a part in fertilization of an egg, controls several developmental process and may regulate cellular processes like metabolism or
In human anatomy [ edit ] In the ear, the extremities of the ductus cochlearis are closed; the upper is termed the lagena and is attached to the cupula at the upper part of the helicotrema ; the lower is lodged in the recessus cochlearis of the vestibule .
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.
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 ...
