~ ~ ~ Sentence 85 ~ ~ ~
To the right and left above (in the episoma) are the thick muscular plates ( m ); below (in the hyposoma) the gonads ( g ).
~ ~ ~ Sentence 236 ~ ~ ~
(From Boveri ) a aorta (here double), b atrium, c chorda, co umlaut cœloma (body-cavity), e endostyl (hypobranchial groove), g gonads (ovaries), kb gill-arches, kd branchial gut, l liver-tube (on the right, one-sided), m muscles, n renal canals, r spinal cord, sn spinal nerves, sp gill-clefts.
~ ~ ~ Sentence 22 ~ ~ ~
Both kinds of cells pass first into the mantle-cavity after the opening of the gonads, proceed through the gill-clefts into the branchial gut, and are discharged from this through the mouth.
~ ~ ~ Sentence 93 ~ ~ ~
The lower or ventral segments, the hyposomites, corresponding to the lateral plates of the craniote-embryo, fuse together in the upper part owing to the disappearance of their lateral walls, and thus form the later body-cavity (metacœl); in the lower part they remain separate, and afterwards form the segmental gonads.
~ ~ ~ Sentence 142 ~ ~ ~
As regards the remaining organs of the Amphioxus, we need only mention that the gonads or sexual glands are developed very late, immediately out of the inner cell-layer of the [ 196 ] body-cavity.
~ ~ ~ Sentence 93 ~ ~ ~
These gonads are not yet independent sexual glands, but sexually differentiated cell-groups in the medullary substance, or, in other words, parts of the gut-wall.
~ ~ ~ Sentence 116 ~ ~ ~
The earliest of these organs are the sexual organs; they are very variously constructed in the Platode-class; in the simplest case there are merely two pairs of gonads or sexual glands-a pair of testicles (Fig.
~ ~ ~ Sentence 123 ~ ~ ~
The gonads are among the oldest organs, the few other organs that we find in the Platodes between the gut-wall and body-wall being later evolutionary products.
~ ~ ~ Sentence 144 ~ ~ ~
The chief advances were the formation of gonads and nephridia, and of the rudimentary brain.
~ ~ ~ Sentence 165 ~ ~ ~
Behind are a pair of simple sexual glands or gonads (Fig.
~ ~ ~ Sentence 203 ~ ~ ~
From the latter they have inherited: (1) The bilateral type, with incomplete segmentation; (2) the ciliary coat of the soft epidermis; (3) the double rows of gastric pouches, alternating with a single or double row of gonads; (4) separation of the sexes (the Platode ancestors were hermaphroditic); (5) the ventral mouth, underneath a protruding snout; (6) the anus terminating the simple gut-tube; and (7) several parallel blood-canals, running the length of the body, a dorsal and a ventral principal stem.
~ ~ ~ Sentence 229 ~ ~ ~
This olfactory tube would afterwards become the nervous centre, while the expanding gonads (lying to right and left of the primitive mouth) would form the cœloma.
~ ~ ~ Sentence 317 ~ ~ ~
The simple cœlom-pouches divide by a frontal septum into two on each side; the dorsal pouch (episomite) forms a muscle-plate; the ventral pouch (hyposomite) forms a gonad.
~ ~ ~ Sentence 70 ~ ~ ~
At first, male and female individuals differ only in the possession of one or other kind of gonads; in other respects they were identical, as we still find in the Amphioxus and the Cyclostomes.
~ ~ ~ Sentence 82 ~ ~ ~
In the Sponges and lowest Hydropolyps isolated cells are detached from the cell-strata of the two primary germinal layers, and become free sexual cells; but in the Cnidaria and Platodes we find these associated in groups which we call sexual glands ( gonads ).
~ ~ ~ Sentence 89 ~ ~ ~
Particularly interesting in connection with the question of the first origin of the gonads are the lowest forms of the Platodes, the Cryptocœla that have of late been separated as a special class ( Platodaria ) from the Turbellaria proper (Fig.
~ ~ ~ Sentence 97 ~ ~ ~
In the great majority of the Bilateria or Cœlomaria it is the mesoderm from which the gonads develop.
~ ~ ~ Sentence 99 ~ ~ ~
In the real Enterocœla, in which the mesoderm appears from the first in the shape of a couple of cœlom-pouches, these are very probably the original gonads (p. 194).
~ ~ ~ Sentence 125 ~ ~ ~
They only unite afterwards to form a pair of simple gonads.
~ ~ ~ Sentence 136 ~ ~ ~
This ventral gonad then develops into the ovary in the female Craniotes, and the testicles in the male.
~ ~ ~ Sentence 187 ~ ~ ~
m' uppermost end of same (Fallopian hydatid), g gonad (sexual gland).
~ ~ ~ Sentence 202 ~ ~ ~
Quite in harmony with this new conception of the equivalence of the two gonads, or the equal physiological importance of the male and female sex-cells and their equal share in the process of heredity, is the important fact established by Hertwig (1875), that in normal impregnation only one single spermatozoon [ 58 ] copulates with one ovum; the membrane which is raised on the surface of the yelk immediately after one sperm-cell has penetrated (Fig.

Gonads: the sexual glands.
~ ~ ~ Sentence 9 ~ ~ ~
THE ADRENAL GLANDS, GONADS, AND THYMUS IV.
~ ~ ~ Sentence 1,238 ~ ~ ~
CHAPTER III THE ADRENAL GLANDS, THE GONADS, AND THYMUS Like the pituitary, each adrenal gland is a double gland, that is, consists of two distinct portions, united together, one might say, by the accident of birth.
~ ~ ~ Sentence 1,427 ~ ~ ~
THE GONADS (_Sexual, Puberty or Interstitial Glands_) The gonads is the name applied to the generative or reproductive glands considered collectively.
~ ~ ~ Sentence 1,433 ~ ~ ~
A classic example of a gland of internal secretion lodged in the interstices of a gland of external secretion is thus furnished by the gonads.
~ ~ ~ Sentence 1,452 ~ ~ ~
These so-called secondary sexual characteristics are an expression of the influence of the internal secretion of the gonads, or the interstitial glands.
~ ~ ~ Sentence 1,524 ~ ~ ~
Removal of the thymus hastens the development of the gonads.
~ ~ ~ Sentence 2,178 ~ ~ ~
When there is equilibrium between the pituitary and the gonads, the teeth will be regular in shape and position.
~ ~ ~ Sentence 2,582 ~ ~ ~
The masculine personality, the combination of masculine, e.g., adrenal cortex and gonad internal secretion predominance, is built for aggression.
~ ~ ~ Sentence 2,954 ~ ~ ~
EXPRESSIONISM AND EXHIBITIONISM We need a detailed examination of the various forms of expression art has differentiated into, in its relation to exhibitionism and as effects of the circulating libido-producing substance of the gonads.
~ ~ ~ Sentence 2,956 ~ ~ ~
The male's attitude, aggressive pursuit, is instigated by the compound adrenal and gonad endocrines.
~ ~ ~ Sentence 2,957 ~ ~ ~
The female's various emulsions of coyness and display are motivated by posterior pituitary and gonad hormones in alliance.
~ ~ ~ Sentence 2,961 ~ ~ ~
But others display signs of sex differentiation that are to be traced back to an awakening interstitial gonad action.
~ ~ ~ Sentence 2,963 ~ ~ ~
Others will show an intense curiosity spontaneously, a curiosity which perhaps may be explained as a larval precocity, dependent upon the minimum of sex hormone production by the gonads.
~ ~ ~ Sentence 3,220 ~ ~ ~
With the advent of the gonads upon the scene, judgments become the centre of the play's plot undoubtedly.
~ ~ ~ Sentence 3,521 ~ ~ ~
We know also that the thyroid dominant tends to be irritable and excitable, the pituitary deficient to be placid and gentle, the adrenal dominant to be assertive and pugnacious, the thymus-centered to be childish and easy-go-lucky and the gonad deficient to be secretive and shy.
~ ~ ~ Sentence 3,554 ~ ~ ~
The endocrine criteria, more exact and concrete, divide them into the adrenal centered, the thyroid centered, the thymus centered, the pituitary centered, the gonad centered, and their combinations.
~ ~ ~ Sentence 3,958 ~ ~ ~
They may be rather gonad unstable with a corresponding instability of the entire endocrine system.
~ ~ ~ Sentence 4,030 ~ ~ ~
Mumps may achieve the same results because of the inflammation of the gonads that may accompany or follow it.
~ ~ ~ Sentence 4,550 ~ ~ ~
So one may list: Infancy as the epoch of the thymus Childhood as the epoch of the pineal Adolescence as the epoch of the gonads Maturity as the epoch of whatever gland is left in control as the result of the life struggle.
~ ~ ~ Sentence 4,620 ~ ~ ~
This fact, together with a number of others, make clear that while the gonads may be the jeune premier of the drama, the vitality of the plot depends upon the other endocrines.
~ ~ ~ Sentence 4,638 ~ ~ ~
The problem of rejuvenation is the problem of recharging, or replacing all of the glands of internal secretion, at least the most important, the thyroid, the pituitary and the adrenals, as well as the gonads.
~ ~ ~ Sentence 4,777 ~ ~ ~
Mumps is a sickness that sometimes permanently injures the gonads: the testes or ovaries.
~ ~ ~ Sentence 4,816 ~ ~ ~
A woman who is gonad deficient with a superior adrenal will suffer from virilism and specialize in the extreme tactics and mythology of the feminist movement.
~ ~ ~ Sentence 4,917 ~ ~ ~
These traits appear only when the hormones occur which are present in one sex and that only when the gonads of that sex are mature.
~ ~ ~ Sentence 4,929 ~ ~ ~
An increased or decreased representation of it in the reproductive sex cells in the gonads.
~ ~ ~ Sentence 5,085 ~ ~ ~
Upon the basis of these structural, functional and mental differences, the qualitative and quantitative evolution of which in the race as in the individual is guided by the glands of internal secretion, Keith presents a very good case for the view that the white man is an example of relative excess of the pituitary, thyroid, adrenal and gonad endocrines.
~ ~ ~ Sentence 5,093 ~ ~ ~
There is every reason then for believing that the white man possesses more of pituitary, adrenal, gonad, and thyroid internal secretions as compared with the yellow man or black man.
~ ~ ~ Sentence 5,153 ~ ~ ~
