When two atoms bonded by a covalent bond have the same electronegativity the electrons will be equally shared. This is called pure (non-polar) covalent bonding. For example, the chlorine molecule, Cl 2.or example, sodium (a metal) combining with chlorine (a non-metal). Covalent, polar covalent and ionic bonding can be considered as forming a spectrum.As the difference in electronegativity increases the bonds become more polar then ionic. 1  Page. 2  1. 3  2. 4  3.
For the vein, see Superficial temporal vein. In human anatomy, the superficial temporal artery is a major artery of the head. It arises from the external carotid artery when it bifurcates into the superficial temporal artery and maxillary artery. Its pulse is palpable superior to the zygomatic arch, anterior and superior to the tragus.
Temporal arteritis is a condition that causes inflammation of arteriesâthe blood vessels that carry oxygen-rich blood from the heart. The exact cause of temporal arteritis is unknown, but the in-flammation appears to be a result of the immune system overreacting and attacking the bodyâs own tissues.hen a patient has temporal arteritis, the biopsy shows inflammation and narrowing of the artery. This is a simple procedure done in a doctorâs office. After a small injection of anesthesia, an incision is made just above the ear. A piece of the temporal artery (usually one or more centimeters) is then cut and removed.
