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.
(Giant Cell Arteritis). Temporal arteritis, also known as giant cell arteritis, is an inflammatory condition that affects the medium to large arteries in the body. It is a systemic condition, which means that any medium to large artery in any part of the body can be affected. This includes the eye, brain and heart.emporal artery biopsy: This is performed under local anesthesia and can take up to 40 minutes. It involves shaving hair from your temple and then making a 1 to 2 inch incision. A small piece of your superficial temporal artery is removed and sent to the laboratory for histopathological analysis.
