The brain is the center of the nervous system in all vertebrate and most invertebrate animals — only a few invertebrates such as sponges, jellyfish, adult sea squirts and starfish do not have one, even if diffuse neural tissue is present.

Nonvascular plants are embryophytes that do not have vascular tissue: mosses, liverworts, and hornworts.

The morphologic variations in the size, shape, volume, tissue density, pectoral locale, and spacing of the breasts determine their natural shape, appearance, and configuration upon the chest of a woman ; yet such features do not indicate its mammary-gland composition ( fat-to-milk-gland ratio ), nor the potential for nursing an infant child.

As they do not have bone marrow, red blood cells are produced in the spleen and the epigonal organ ( special tissue around the gonads, which is also thought to play a role in the immune system ).

A major problem has been that bacteria do not consume all parts of the malignant tissue.

Although the teeth do not consist of tissue commonly found in other bones, the teeth are considered bones and are a member of the skeletal system.

Even when tracheids do take a structural role, they are supported by sclerenchymatic tissue.

In contrast, substances that destroy tissue but do not absorb, such as lye, are classified as corrosives rather than poisons.

It is presumed that this complex apparatus, including the barbs on the sting, evolved specifically in response to predation by vertebrates, as the barbs do not usually function ( and the sting apparatus does not detach ) unless the sting is embedded in fleshy tissue.

Fluids do not compress, while the tissue surrounding the organs of these animals will compress.

An exception to this is animals with regeneration, which do not form scars and the tissue will grow back exactly as before.

For example, scars in the skin are less resistant to ultraviolet radiation, and sweat glands and hair follicles do not grow back within scar tissue.

This scar type is sunken, because the collagen bundles do not overextend the tissue.

Sweat glands do not form in scar tissue, which impairs the regulation of body temperature.

In unwounded tissue, these fibers are not overexpressed with thick collagen and do not contract.

However, drugs delivered directly to the CSF do not effectively penetrate into the brain tissue itself, possibly due to the tortuous nature of the interstitial space in the brain.

Contrary to a common misconception, echinoderms do not possess an exoskeleton, as their test is always contained within a layer of living tissue.

Usually, males ' nipples do not change much past this point ; however, some males develop a condition known as gynecomastia, in which the fatty tissue around and under the nipple develops into something similar to a female breast.

Benign adenomas typically do not invade other tissue and rarely metastasize.

These enzymes can cause localized tissue necrosis ( which may be similar to that caused by a recluse bite ), though the symptoms are less severe and do not result in the systemic effects occasionally seen with recluse envenomations.

" Flesh-eating bacteria " is a misnomer, as the bacteria do not actually " eat " the tissue.

The flukes ( lobes of the tail ) and dorsal fin are formed of dense connective tissue and do not contain bone or muscle.

If these procedures do not yield enough tissue, more extensive diagnostic surgery may be necessary.

The technical distinction between the two types of mushrooms is that polypores do not have the spore-bearing tissue continuous along the entire underside of the mushroom.

`` What is it you want me to do, Mr. Brenner ''??

`` All I have to do to set the record is to go on down.

It is not good, Mr. Waddell: you will do him great harm ''.

`` All right, if you can't do your arithmetic during school hours you can do it after school is out '', Miss Langford said firmly, not smiling.

It became the sole `` subject '' of `` international law '' ( a term which, it is pertinent to remember, was coined by Bentham ), a body of legal principle which by and large was made up of what Western nations could do in the world arena.

On Fridays, the day when many Persians relax with poetry, talk, and a samovar, people do not, it is true, stream into Chehel Sotun -- a pavilion and garden built by Shah Abbas 2, in the seventeenth century -- but they do retire into hundreds of pavilions throughout the city and up the river valley, which are smaller, more humble copies of the former.

But more important, and the thing which the casual traveler and the blind sojourner often do not see, is that these places and activities are often the settings in which Persians exercise their extraordinary aesthetic sensibilities.

Since it is not far from Viareggio, he will visit Puccini's house, as he never fails to do, to pay his respects to the memory of the composer of La Boheme, which he considers one of Puccini's masterpieces.

So great a man could not but understand, too, that the thing that moves men to sacrifice their lives is not the error of their thought, which their opponents see and attack, but the truth which the latter do not see -- any more than they see the error which mars the truth they themselves defend.

He catches criminals not merely because he is paid to do so ( frequently he does not receive a fee at all ), but because he enjoys his work, because he firmly believes that murder must be punished.

The assumptions upon which the example shown in Figure 3 is based are: ( A ) One man can direct about six subordinates if the subordinates are chosen carefully so that they do not need too much personal coaching, indoctrinating, etc..

What I am here to do is to report on the gyrations of the struggle -- a struggle that amounts to self-redefinition -- to see if we can predict its future course.

`` The Moral Creed '' and `` The Will To Risk '' live happily together, if we do not examine where the line is to be drawn.

But because it is the function of the mind to turn the one into the other by means of the capacities with which words endow it, we do not unwisely examine the type of distinction, in the sphere of politics, on which decisions hang.

Incest is still a durable theme, but if it wants to get written about it will have to find ways to surprise the emotions, and there is no better way to do this than that of concealment and symbolic representation.

`` The Rocking Horse Winner '' is a fantasy with extraordinary power to disturb the reader -- but we do not know why.

Even if people do, in a not far distant future, begin to read one another's minds, there will still be the question of whether what you find in another man's mind is especially worth reading -- worth more, that is, than what you can read in good books.

The first thing to do is get her some money by a temporary but definite adjustment pending a final disposition of the case.

When I take over Taliesin, the first thing I'll do is fire you ''.

Not for a moment do we forget that our own fate is firmly fastened to that of these countries ; ;

I do not know that this is true ; ;
