~ ~ ~ Sentence 414 ~ ~ ~
To the right and left above (in the episoma) are the thick muscular plates (m); below (in the hyposoma) the gonads (g).
~ ~ ~ Sentence 543 ~ ~ ~
(From Boveri) a aorta (here double), b atrium, c chorda, co umlaut coeloma (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 660 ~ ~ ~
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 715 ~ ~ ~
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 (metacoel); in the lower part they remain separate, and afterwards form the segmental gonads.
~ ~ ~ Sentence 760 ~ ~ ~
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 body-cavity.
~ ~ ~ Sentence 856 ~ ~ ~
In the horse and ass it takes a little longer, forty-three to forty-five weeks; in the camel, thirteen months.
~ ~ ~ Sentence 1,611 ~ ~ ~
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 1,628 ~ ~ ~
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 (Figure 2.241 h) and a pair of ovaries (e).
~ ~ ~ Sentence 1,632 ~ ~ ~
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 1,642 ~ ~ ~
The chief advances were the formation of gonads and nephridia, and of the rudimentary brain.
~ ~ ~ Sentence 1,669 ~ ~ ~
Behind are a pair of simple sexual glands or gonads (Figure 2.243 e).
~ ~ ~ Sentence 1,703 ~ ~ ~
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 1,726 ~ ~ ~
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 coeloma.
~ ~ ~ Sentence 2,845 ~ ~ ~
The simple coelom-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 5,518 ~ ~ ~
Gonads, the.
