|
Answer» 1) The peripheral nervous system consists of nerves that arise from the brain and spinal cord.2) The peripheral nervous system has 43 pairs of nerves of these 12 pairs are called CRANIAL NERVES and the rest of 31 pairs are called SPINAL NERVES.3) The grey matter of the spinal cord appears like butterfly or in the shape of letter ‘H’. Each segment of the ‘H’ shaped grey matter is called ‘HORNS’.4) The upper horns are called \'DORSAL HORNS’ and the lower horns are called ‘VENTRAL HORNS’.5) The sensory fibres originate from the dorsal horn of the spinal cord; They carry information from body organs to spinal cord.6) The motor, fibres take their origin from the ventral horns of the spinal cord.

Why carbon can neither form C4, |
|
Answer» Because loose of 4electron required more energy so it can not form c4 In simple words if carbon form c4 then it will be difficult for nucleus to lose 4 electrons or large amount of energy will required to lose 4 electrons so they cannot form c4 Bcoz carbon has four valence electrons in their outer most shell and they can be stable by gaining 4 more electrons to complete its octet Thats why they cannot form c4+ cations or c4- anions. Carbon is unable to form C4− anion as its nucleus with six protons will not be able to hold ten electrons. Thus, carbon achieves noble gas electronic configuration by sharing its four electrons with other elements, i.e. it forms covalent compounds. According to energy conservation carbon is not able to lose four electron or gain another four electron due to its small size.Therefore it shares electron forming covalent bonds |
