Structure


The adult human brain weighs on the average concerning one.5 kg (3.3 lb) with a volume of around 1130 cuboid centimetres (cm3) in ladies and 1260 cm3 in men, though there's substantial individual variation. medical specialty variations between the sexes haven't been shown to correlate in any easy manner with IQ or different measures of psychological feature performance. The human brain consists of neurons, interstitial tissue cells, and blood vessels. the amount of neurons, in keeping with array imaging, has been shown to be concerning eighty six billion neurons within the human brain with a roughly equal range of non-neuronal cells known as interstitial tissue.The cerebral hemispheres (the cerebrum) type the biggest a part of the human brain and area unit located higher than different brain structures. they're coated with a plant tissue layer (the cerebral cortex) that features a convoluted topography. beneath the neural structure lies the brain-stem, resembling a stalk on that the neural structure is hooked up. At the rear of the brain, to a lower place the neural structure and behind the brain-stem, is that the neural structure, a structure with a horizontally rutty surface, the neural structure cortex, that creates it look completely different from the other brain space. constant structures area unit gift in different mammals, though they vary significantly in relative size. As a rule, the smaller the neural structure, the less convoluted the cortex. The cortex of a rat or mouse is nearly utterly sleek. The cortex of a dolphin or whale, on the opposite hand, is additional convoluted than the cortex of a person's.The living brain is incredibly soft, having a consistency like soft gelatin or soft curd. though stated as substantia grisea, the live cortex is pinkish-beige in color and slightly off-white within the interior.

What Is Melting Points

Most organic compounds have melting points below 200 ºC. Some decompose before melting, a few sublime, but a majority undergo repeated melting and crystallization without any change in molecular structure. When a pure crystalline compound is heated, or a liquid cooled, the change in sample temperature with time is roughly uniform. However, if the solid melts, or the liquid freezes, a discontinuity occurs and the temperature of the sample remains constant until the phase change is complete. This behavior is shown in the diagram on the right, with the green segment representing the solid phase, light blue the liquid, and red the temperature invariant liquid/solid equilibrium. For a given compound, this temperature represents its melting point (or freezing point), and is a reproducible constant as long as the external pressure does not change. The length of the horizontal portion depends on the size of the sample, since a quantity of heat proportional to the heat of fusion must be...

What Is Atomic And Molecular Orbitals

A more detailed model of covalent bonding requires a consideration of valence shell atomic orbitals. For second period elements such as carbon, nitrogen and oxygen, these orbitals have been designated 2 s , 2p x , 2p y   & 2p z . The spatial distribution of electrons occupying each of these orbitals is shown in the diagram below.   Very nice displays of orbitals may be found at the following sites: J. Gutow, Univ. Wisconsin Oshkosh R. Spinney, Ohio State  M. Winter, Sheffield University The valence shell electron configuration of carbon is 2 s 2 , 2p x 1 , 2p y 1  & 2p z 0 . If this were the configuration used in covalent bonding, carbon would only be able to form two bonds. In this case, the valence shell would have six electrons- two shy of an octet. However, the tetrahedral structures of methane and carbon tetrachloride demonstrate that carbon can form four equivalent bonds, leading to the desired octet. In order to explain this covalent bonding,...

Uses OF Alkynes In Nature And Medicine

-
Alkynes in nature and medicine According to Ferdinand Bohlmann, the first naturally occurring acetylenic compound, dehydromatricaria ester, was isolated from an Artemisia  species in 1826 . Polyynes, a subset of this class of natural products, have been isolated from a wide variety of plant species, cultures of higher fungi, bacteria, marine sponges, and corals.  Some acids like  tariric acid  contains an alkyne group. Diynes and triynes, species with the linkage RC ≡ C-C ≡ CR' and RC ≡ C-C ≡ C-C ≡ CR' respectively, occur in certain plants ( Ichthyothere , Chrysanthemum ,  Cicuta ,  Oenanthe  and other members of the  Asteraceae  and  Apiaceae  families).  Some examples are  cicutoxin , oenanthotoxin ,  falcarinol  and  carotatoxin . These compounds are highly bioactive, e.g. as  nematocides .  1-Phenylhepta-1,3,5-triyne is illustrative of a naturally occurring triyne. Alkynes occ...
