The vascular bundles of the third series are found just away from the ring and separated from it by a few layers of parenchymatous cells.
Two rows of vascular bundles surround a fairly large amount of parenchymatous cells of the ground tissue.
The spaces existing between the vascular bundles and the epidermis are filled with parenchymatous cells.
So the parenchymatous cells of the cortex lying outside the sclerenchymatous ring are divided into small isolated areas.
In the stem of Eriochloa polystachya, all the vascular bundles are more or less peripheral in position leaving a wide area of parenchymatous cells in the centre.
The cortex has a number of fairly large air-cavities separated by bands of parenchymatous cells.
In the transverse sections of these roots we find a fairly broad cortex consisting of thin-walled parenchymatous cells more or less regularly arranged.

Certain diseases affect the parenchymatous tissue in an organ more than the interstitial tissue and again others affect the blood vessels particularly.
Under such circumstances the parenchymatous cells often undergo what is termed pressure atrophy; they are diminished by squeezing.
In support of this assertion, attention is called to certain interstitial and parenchymatous alterations frequently demonstrable in the nerves of the affected part.

The thyreoid is enlarged, but instead of the uniform enlargement which characterises the parenchymatous goitre, it tends to be uneven, with hillocky projections corresponding to the individual cysts (Fig.
The effects upon the trachea are more decided and more progressive than in parenchymatous goitre; it displaces and compresses the trachea and frequently overlaps it, so as to bury the air-passage completely.
The outer one is stated to form the circular and longitudinal muscles; the inner one to give rise to a muscular reticulum, the spaces within which constitute the parenchymatous body cavity.
While the solid parenchymatous digestive canal of Convoluta and Schizoprora and other forms amongst the Turbellarians, though very probably secondary, may perhaps be explained by such a view of their origin.
It arises long before any of the other tentacles as a single anterior prolongation of the prae-oral lobe containing a parenchymatous cavity, which communicates freely with the general perivisceral cavity.

This occurred as surface extravasation and in the form of parenchymatous hæmorrhages.
This condition may be followed by complete disorganisation of the cord, accompanied or not by multiple parenchymatous hæmorrhages into its substance.
As to the causation of the 'radiation' symptoms, it is difficult to discriminate the effects of neighbouring parenchymatous hæmorrhages from those of local vibratory concussion of the nervous tissue.
Inflammations of the kidneys have been differentiated widely, according as they were acute or chronic, parenchymatous or tubal, suppurative or not, with increased or shrunken kidney, etc.
The kidneys may appear normal or anemic and flaccid, but microscopically they usually show a chronic parenchymatous degeneration.
The large medullary rays give to the wood a characteristic parenchymatous or lax appearance, which is in marked contrast to the more compact wood of a conifer.
In the wood of Cypressus, Cedrus, Abies and several other genera, parenchymatous cells occur in association with the xylem-tracheids and take the place of the resin-canals of other types.
When tracheids occur in the medullary rays of the xylem these are replaced in the phloem-region by irregular parenchymatous cells known as albuminous cells.
The characteristic companion-cells of Angiosperms are represented by phloem-parenchyma cells with albuminous contents; other parenchymatous elements of the bast contain starch or crystals of calcium oxalate.
In a radial section of a pine stem each ray is seen to consist in the median part of a few rows of parenchymatous cells with large oval simple pits in their walls, accompanied above and below by horizontal tracheids with bordered pits.
The main anatomical features of a cycad stem may be summarized as follows: the centre is occupied by a large parenchymatous pith traversed by numerous secretory canals, and in some genera by cauline vascular bundles (e.
The majority of the lichens, however, possess a stratified thallus in which the gonidia are found as a definite layer or layers embedded in a pseudo-parenchymatous mass of fungal hyphae, i.
By the fusion of the hyphae in the middle of the mycelium a pseudo-parenchymatous cortical layer has begun to form.
The liver showed a slight degree of parenchymatous degeneration, the congestion making prominent the structure of the organ.
The centres of the acini showed parenchymatousand fatty degeneration.
The cells of the kidney showed various degrees of degeneration, ranging from parenchymatous to fatty infiltration.
The central parenchymatous cells are larger, more loosely attached together, and have more delicate walls than the more superficial cells.
If the impulse travels down the exterior cells, it would have to cross from between twenty to thirty transverse partitions; but rather fewer if down the inner parenchymatous tissue.
The study of the vertebrate embryo asserts that the cartilaginous skeleton arose as simple branchial bars and a simple cranio-facial skeleton, and also that the parenchymatous variety of cartilage represents the embryonic form.
The cartilage so formed was not like hyaline cartilage, but resembled in a striking manner parenchymatous cartilage.
In the connective tissue group, bone is confined to the vertebrates, cartilage is found among invertebrates, and the closest resemblance to vertebrate embryonic or parenchymatous cartilage is found in the cartilage of Limulus.
Of these, the parenchymatous cartilage is looked upon as the most primitive form, because it preserves without modification the characters of embryonic cartilage.

After death post-mortem decomposition rapidly sets in, the blood is sticky, and swelling is found in the various parenchymatous organs.
This becomes relatively greater in the course of time, and the parenchymatous cells become degenerated and absorbed.
These changes Hoffmann,[47] who has specially studied them, is inclined to place by the side of the parenchymatous degeneration of other organs.
It is scarcely severe enough to merit the name desquamative, tubal, or parenchymatous nephritis, though it is a mild form of the same pathological state.
Parenchymatous inflammation is manifested by a degeneration of the cells affected.
Interstitial inflammations are likely to become chronic in character, and, from the outset, are usually associated with parenchymatous changes.
The study of this condition in the kidneys is further of interest as indicating that the border-line between a parenchymatousdegeneration and a parenchymatous inflammation is purely arbitrary.
Kyber,[36] the latest investigator, in opposition to this view maintains that this affection is not limited to the connective tissue, but may also be seated in the parenchymatous cells of organs.
Many authorities regard this granular or parenchymatous degeneration as closely allied to fatty degeneration, since many of the causes which produce the one occasion the other.
When hemorrhage does attend malarial fevers, it may occur from one or another of a variety of surfaces or into shut cavities or in parenchymatous structures.
