See, my organs cannot be damaged and my metabolism processes liquor much faster than yours.
The eggs of the female give rise to embryos within the body of the mother; her other organs undergo a retrogressive change and serve as food for the young, until the body-wall only of the mother remains as a brown capsule.
The juntas are in this respect organs of~the administrative jurisprudence created in Italy by the law of the 1st of May 1890, in order to provide juridical protection for those rights and interests outside the competence of the ordinary tribunals.
(2) Sensory cells, which may be fairly numerous in places, especially on the tentacles, but which occur always scattered and isolated, never aggregated to form sense-organs as in the medusa.
The sense-cells form, in the first place, a diffuse system of scattered sensory cells, as in the polyp, developed chiefly on the manubrium, the tentacles and the margin of the umbrella, where they form a sensory ciliated epithelium covering the nerve-centres; in the second place, the sense-cells are concentrated to form definite sense-organs, situated always at the margin of the umbrella, hence often termed " marginal bodies."
29); secondly, organs commonly termed otocysts, on account of their resemblance to the audi tory vesicles of higher After 0.
In Hydromedusae the sense-organs are always exposed at the umbrellar margin (hence Gymnophthalmata), while in Scyphomedusae they are covered over by flaps of the umbrellar margin (hence Steganophthalmata).
Beyond this simple condition the visual organs of the Hydromedusae do not advance, and are far from reaching the wonderful development of the eyes of Scyphomedusae (Charybdaea).
Organs of Hydro FIG.
Brooks regards these organs as sensory, serving for the sense of balance, and representing a primitive stage of the tentaculocysts of Trachylinae; Linko, on the other hand, finding no nerve-elements connected with them, regards them as digestive (?) in function.
In this way the medusa sinks from an independent per sonality to an organ of the polyp-colony, becoming a so-called medusoid gonophore, or bearer of the reproductive organs, and losing gradually all organs necessary for an independent existence, namely those of sense, locomotion and nutrition.
Here the medusoid, attached by the centre of its ex-umbral surface, has lost its velum and sub-umbral muscles, its sense organs and mouth, though still retaining rudimentary tentacles.
To sum up, the entocodon is a precocious formation of the umbrella, closing over to protect the organs in the umbrellar cavity.
Balfour put forward the view that the polyp was the more primitive type, and that the medusa is a special modification of the polyp for reproductive purposes, the result of division of labour in a polypcolony, whereby special reproductive persons become detached and acquire organs of locomotion for spreading the species.
She continued to exercise her vocal organs mechanically, as ordinary children do.
Associated with these males are neuter zooids, which usually possess no functional repro ductive organs, but have in I -...
They are composed of only from ' six to nine segments, which are beset with prominent spines, some of the latter appearing to be organs of special sense.
Uzel, with the majority of students, regards the paired organs as mandibles and the unpaired as an epipharynx.
Varese is the seat of active silkspinning, tanning, paper-making and the manufacture of organs and vehicles.
This observation led him to further work, and he succeeded in showing that in vascular organs the presence of cells in inflammatory exudates is not the result of exudation but of multiplication of pre-existing cells.
The classification into epithelial organs, connective tissues, and the more specialized muscle and nerve, was largely due to him; and he proved the presence of neuroglia in the brain and spinal cord, discovered crystalline haematoidine, and made out the structure of the umbilical cord.
The nerves conduct the animal spirits to act upon the muscles, and in their turn convey the impressions of the organs to the brain.
But, on the other hand, the vital spirits cause a movement in the gland by which the mind perceives the affection of the organs, learns that something is to be loved or hated, admired or shunned.
Any note may be a pitch note; for orchestras custom has settled upon a' in the treble clef, for organs and pianos in Great Britain c 2, and for modern brass instruments b flat'.
But a positive identity of pitch cannot be claimed for any period of time, and certainly not for the early organs; the foot-rule of the organ-builder, which had to do with the lengths of the pipes, and which varied in every country and province, could easily cause a difference of a semitone.
Nearly all the German organs in his time were tuned to this higher pitch.
Sir Frederick Gore Ouseley (vide Ellis's lecture) regarded the French ton de chapelle as being about a minor third below the Diapason Normal, a' 435, and said that most of the untouched organs in the French cathedrals were at this low pitch.
Ellis quotes an organ at Lille, a' 374.2, but no other instance of the very low Schlick pitch is recorded, although trial of the French cathedral organs might perhaps result in the finding of examples.
Silbermann's 18th-century Dresden pitch, a' 415, and the organs of Renatus Harris, a' 428.7.
The high pitch remains only where there are large concert organs not yet lowered, and with the military and brass bands.
The actual piercing organs are the mandibles, while the upper lip or labrum forms a sucking tube.
The maxillae are not piercing organs, and their function is to protect the mandibles and labrum and separate the hairs or feathers of the host.
Organs used to be regarded as contrary to New Testament example, but their use is now all but universal.

We pass on to the other curious order of non-placental mammals, that of the Monotremata, so called from the structure of their organs of evacuation with a single orifice, as in birds.
It but remains to call attention to the fact that the earlier view of the liver as the seat of the soul gave way among many ancient nations to the theory which, reflecting the growth of anatomical knowledge, assigned that function to the heart, while, with the further change which led to placing the seat of soul-life in the brain, an attempt was made to partition the various functions of manifestations of personality among the three organs, brain, heart and liver, the intellectual activity being assigned to the first-named; the higher emotions, as love and courage, to the second; while the liver, once the master of the entire domain of soul-life as understood in antiquity, was degraded to serve as the seat of the lower emotions, such as jealousy, anger and the like.
Similarly the giant cells are produced at their periphery into a number of branching processes which bear similar end-organs on their surface and in some cases terminate in them.
From the shape and position of the phagocytic organs it is obvious that they form admirable strainers through which the fluid of the body-cavity filters (figs.
- One of the phagocytic organs of Sc. armatum, highly magnified.
2, One of the processes and end organs of the same.
The worm inhabits the lung of the frog and toad, and is hermaphrodite (Schneider) or parthenogenetic (Leuckart); the embryos hatched from the eggs find their way through the lungs into the alimentary canal and thence to the exterior; in a few days they develop into a sexual larva, called a Rhabditiform larva, in which the sexes are distinct; the eggs remain within the uterus, and the young when hatched break through its walls and live free in the perivisceral cavity of the mother, devouring the organs of the body until only the outer cuticle is left; this eventually breaks and sets free the young, which are without teeth, and have therefore lost the typical Rhabditis form.
The reproductive organs do not begin to appear until the larva has twice cast its skin.
After the second larval moult, he passes through a passive stage comparable to the pupa-stadium of an b insect, and during this stage, which occurs inside the root, the reproductive organs are perfected.
As in other cases where animal colonies are formed by organic union of separate individuals, there is ever a tendency for the polyp-colony as a whole to act as a single individual, and for the members to become subordinated to the needs of the colony and to undergo specialization for particular functions, with the result that they simulate organs and their individuality becomes masked to a greater or less degree.

Is it possible to replace all our organs with freshly grown new ones created from our own cells?
The reproductive individuals have undergone an extraordinary simplification of the organs concerned with the collection and digestion of food.
When her vocal organs needed exercise, which was usually toward seven o'clock when she had had an after-dinner rest in a darkened room, the pretext would be the retelling of the same stories over and over again to the same audience.
The reproductive organs of Rhabdopleura have but seldom been observed.
Before describing the process of teaching Helen to speak, it may be well to state briefly to what extent she had used the vocal organs before she began to receive regular instruction in articulation.
