in diameter, with little yolk, and the embryos provided with large trophic vesicles (Willey).
The backward-directed epipods usually carry branchial vesicles.
v, Seminal vesicles.
A viral culture swab from the vesicles will confirm the infection and then either topical or systemic acyclovir will be used as treatment.
cleavage of these proteins precludes fusion of the vesicles with the nerve membrane, thereby preventing release of neurotransmitters into the neuromuscular junction.
Cytosolic entry of bisphosphonate drugs requires acidification of vesicles after fluid-phase endocytosis.
erythema and/or vesicles.
exocytosis of the vesicles in response to calcium entry into the presynaptic terminal.
This calcium entry then triggers exocytosis of the presynaptic vesicles.
fungusn - but not always - the arbuscular mycorrhizal fungi also produce large, swollen vesicles, which are thought to contain nutrient reserves.
intracellular acidic vesicles, called endosomes (Fig.

The pair of seminal vesicles secrete up to 85% of the total volume of seminal fluid.
The antigens are then processed in a series of intracellular acidic vesicles, called endosomes (Fig.
However, membrane vesicles need not be present at the beginning of translation.
gas vesicles are hollow cylindrical tubes, closed by a hollow, conical cap at each end.
Very many species produce similar spherical BS of about 0.5 micron in diameter with characteristic latticework surface, looking like giant clathrin-coated transport vesicles.
The rarer zeolites tend to crystallize in isolation in small vesicles, often with few or no associated species.
Harvey proceeds to contrast this view with that of the " Medici," or followers of Hippocrates and Galen, who, " badly philosophizing," imagined that the brain, the heart, and the liver were simultaneously first generated in the form of vesicles; and, at the same time, while expressing his agreement with Aristotle in the principle of epigenesis, he maintains that it is the blood which is the primal generative part, and not, as Aristotle thought, the heart.

The enlarged cystic goitres show, in the distended vesicles, an abnormal formation and retention of this substance (fig.
They are hollow, brittle, irregularly pyriform, tuberculated or branched vesicles, with thin walls, covered externally with a grey down, and internally with a white chalk-like matter, and insect-remains (see fig.
SCABIES, or Itch, a skin disease due to an animal parasite, the Sarcoptes scabei (see Mite), which burrows under the epidermis at any part of the body, but hardly ever in the face or scalp of adults; it usually begins at the clefts of the fingers, where its presence may be inferred from several scattered pimples, which will probably have been torn at their summits by the scratching of the patient, or have been otherwise converted into vesicles or pustules.
Viral infections normally develop with small vesicles or pustules on the skin as the first signs that are noticed.
Effects of boldine on mouse diaphragm and sarcoplasmic reticulum vesicles isolated from skeletal muscle.
Gas vesicles are hollow cylindrical tubes, closed by a hollow, conical cap at each end.
Herpetic gingivostomatitis-A severe oral infection that affects children under five years of age; vesicles and ulcerations, edematous throat, enlarged painful cervical lymph nodes occur; chills, fever, malaise, bed breath, and drooling.
The vesicles appear first on the face and legs.
When a child has several of these vesicles close together, they may spread to one another.
Even when impetigo is initially caused by strep bacteria, the vesicles are frequently secondarily infected with staph bacteria.
Characteristic appearance of the skin is the usual method of diagnosis, although fluid from the vesicles can be cultured and then examined in an attempt to identify the causative bacteria.
After one to two days, fluid-filled bumps (vesicles) appear on the inside of the mouth, along the surface of the tongue, on the roof of the mouth, and on the insides of the cheeks.
Occasionally, these vesicles may occur in the diaper region.
The vesicles in the mouth cause the majority of discomfort, and the child may refuse to eat or drink due to pain.
The fluid within the vesicles contains large quantities of the causative viruses.
After another 12 to 24 hours the spots typically become itchy, fluid-filled bumps called vesicles, which continue to appear in crops for the next two to five days.
Cultures are usually obtained from skin vesicles, eyes, mouth, rectum, urine, stool, and blood.
Acute lesions: These include extremely itchy reddened papules (small solid eruptions resembling pimples) and vesicles (small blister-like elevations in the skin surface that contain tissue fluid) over erythematous (reddened) skin.
In Fucus vesiculosus they arise in lateral pairs; in Ascophyllum they are single and median; in Macrocystis one vesicle arises at the base of each thallus segment; in Sargassum and Halidrys the vesicles arise on special branches.
Other granules, easily mistaken for the " starch " granules, are also found in the cells of Phaeophyceae; these possess a power of movement apart from the protoplasm, and are considered to be vesicles and to contain phloroglucin.
The vesicles of Fucaceae and Laminariaceae prevent the sinking of the bulkier forms. But why certain Fucaceae favour certain zones in the littoral region, why certain epiphytes are confined to certain hosts, why Red and Brown Algae are not better represented in fresh water or Green Algae in salt, - these are problems to which it is difficult to find a ready answer.
Such a model, properly constructed, that is to say, with the vesicles of the foam microscopic in size, is a marvellous imitation of the appearance of protoplasm, being distinguishable from it only by a greater symmetry.
Smith) bears very definite terminal, or intercalary, spherical vesicles, which may probably be regarded as reproductive organs - either oiigonia or sporangia.
29); secondly, organs commonly termed otocysts, on account of their resemblance to the audi tory vesicles of higher After 0.
In addition to the stems bearing cups, there are found vesicles associated with them, which have been interpreted as gonothecae or as floats, that is to say, air-bladders, acting as hydrostatic organs for a floating polyp-colony.
not lobed or indented; tentaculocysts usually enclosed in vesicles; gonads on the radial canals.
The sense-organs are tentaculocysts which are usually enclosed in vesicles and may be sunk far below the surface.
- Margin of the umbrellalobed, tentacles arising from the ex-umbrella at some distance from the margin; tentaculocysts exposed, not enclosed in vesicles; gonads on the sub-umbral floor of the stomach or of the gastric pouches.
These ducts therefore have not their exact counterparts in the Oligochaeta, unless we are to assume that they collectively are represented by the seminal vesicles of earthworms and the vasa deferentia.

During pairing he thrusts the tip of these organs into the seminal vesicles of the female and the eggs are fertilized as they pass out of the oviduct.
These vesicles are filled with the colloid material (x 90 diam.) J FIG.
The most remarkable feature of this cystic development is the formation in many genera of several internal buds within a common cyst, each of which forms an independent inverted scolex (Coenurus, Polycercus); or these internal vesicles may bud off a large number of scolices on their external surface (Staphylocystis).
It is probable that these vesicles are not reservoirs, as was at one time thought, but form some special secretion which mixes with that of the testes.
- View of the Base of the Bladder, Prostate, Seminal Vesicles and Vasa Deferentia from behind.
They pass out through short vasa deferentia with internal ciliated funnels, sometimes an enlargement on their course - the seminal vesicles - and a minute external pore situated on the side of the tail.
held together by the adhesion of the cell-walls at the surface of Protosiphon and Botrydium, on the one hand, are minute vesicles contact.
The numerous small blisters or vesicles thus derived coalesce, forming a large sac full of "blister-fluid."
From the above-named isopods the present order is strongly differentiated by having heart and breathing organs not in the pleon, but in the peraeon, or middle body, the more or less simple branchial vesicles being attached to some or all of the last six pairs of trunklegs.
A fragment of such a paste brought into a liquid in which the solid particles are soluble, slowly expands into a honeycomb like foam, the walls of the minute vesicles being films of oil, and the contents being the soluble particles dissolved in droplets of the circumambient liquid.
io) consist of a pair of testes (te), a pair of seminal vesicles (v), vasa deferentia (v.d.), and accessory glandular tubules (f).
