The x-rays were conclusive and indicated a bad infection in the lower lobe of one lung.
C antero-posterior direction, its ventral lobe usually concealing the mouth.
Shell ovoid, with short spire, wide aperture and folded columella; inferior pallial lobe thick; visceral commissure still twisted.
3, e) and the outer lobe is convex and soft.
There is only one right and one left lobe, each traversed through its whole length by a mesobronchium, whence arise about ten secondary bronchia; these send off radially arranged parabronchia, which end blindly near the surface.
Ks.a, Anterior superior lobe of the large nephridium.
An epipodium bearing three pairs of tentacles and an operculigerous lobe with two appendages; inhabitants of the Sargasso weed.
Posteriorly the mantle forms a large pallial lobe FIG.
Visceral mass and shell sinistral; inferior pallial lobe very prominent, and transformed into a branchia.
Shell conical, not spiral; inferior pallial lobe transformed into a branchia.
I, C, ca, st) bearing a distinct inner and outer lobe (lacinia and galea, fig.
No other intermediate stages have as yet been noticed between this arrangement and that of the Heteronemertini, in which a separate posterior brain-lobe receives a similar ciliated canal, and in which the oesophageal outgrowths have made their appearance and are coalesced with the nerve-tissue in the organ of the adult animal.
6 a Oligocene of both hemispheres appears Protapirus, which ranges well into the Miocene, and is essentially a tapir, having lost the third lobe of the last lower molar, and being in process of acquiring molar-like upper premolars, although none of these teeth have two complete inner columns.
Median pallial nerve of dorsal each side, just below the lobe of mantle.
These plates are secreted by the ventral lobe of the mantle, and were named by von Buch in 1834 the " deltidium."
The cerebral mass is in Limulus more easily separated by dissection as a median lobe distinct from the laterally placed ganglia of the cheliceral somite than is the case in Scorpio, but the relations are practically the same in the two forms. Formerly it was supposed that in Limulus both the chelicerae and the next following pair of appendages were prosthomerous, as in Crustacea, but the dissections of Alphonse Milne-Edwards (6) demonstrated VI FIG.
B, Longitudinal lobe or stolon of the coxal gland.
In the latter the single pair of antennae springing up from each side of the camerostome or hypostome or upper lip-lobe are seen.
Pa, Post-anal lobe of the male - a conical body with narrow basal stalk.
Pa, Post-anal lobe of the female (compare the jointed filament in Thelyphonus, fig.
Appendages of 2nd pair not underlying the mouth, but freely movable and, except in primitive forms, furnished with a maxillary lobe; the rest of the limb like the legs, tipped with a single claw and quite unmodified (except in a').
The spinning appendages migrate to the posterior end of the opisthosoma and take up a position close to the anus; the inner branches of the anterior pair either atrophy or are represented homogenetically by a plate, the cribellum, or by an undivided membranous lobe, the colulus.
The perianth consists of five or six oblong greenish lobes, within which is found a tuft, consisting of a large number of stamens, each of which has a very short filament and an oblong two-lobed anther bursting longitudinally, and surmounted by an oblong lobe, which is the projecting end of the connective.
Few have any occipital crest, but several have the face ornamented by the outgrowth of a fleshy lobe or lobes.
- In this division the body is partly covered by a broad shield, united in front with the head; the eyes are sessile, the first antennae are small, the second rudimentary or wanting; of the numerous feet, sometimes sixty-three pairs, exceeding the number of segments to which they are attached, the first pair are more or less unlike the rest, and in the female the eleventh have the epipod and exopod (flabellum and sub-apical lobe of Lankester) modified to form an ovisac. Development begins with a nauplius stage.
A, Shark (Lamna cornubica), with long lobe of tail upturned.
B, Ichthyosaur (Ichthyosaurus quadricissus), with fin-like paddles, long lobe of tail down-turned.
First and second upper premolars with compressed crowns and two roots; and the third and fourth with an inner lobe of the crown, and an additional pair of roots.
To the left of the vena cava is the Spigelian lobe, which lies in front of the bodies of the tenth and eleventh thoracic vertebrae, the lesser sac of peritoneum, diaphragm and thoracic aorta intervening.
To the left of this is the fissure for the ductus venosus, and to the left of this again, the left lobe, in which a broad shallow groove for the oesophagus may usually be seen.
Sometimes the left lobe stretches as far as the left abdominal wall, but more often it ends below the apex of the heart, which is 3 in.
The canine was like a premolar, and in contact with the first tooth of that series; and the cheek-teeth were short-crowned, with the premolar simpler than the molars, and a third lobe to the last lower tooth of the latter series.
Lobe-like processes of the t, Cephalic tentacles.
These frail insects, the majority of which have wings of the type described above, are further characterized by the presence of minute but distinct maxillulae, while the inner lobe (lacinia) of the first maxilla is an elongate, hard structure (the " pick," fig.
At the base of each wing projects a dorsal lobe - the jugumand the neuration is predominantly longitudinal, resembling so closely that of the lower Lepidoptera (q.v.) that a nearer relationship of the Trichoptera to that order than to any group of the old Linnean Neuroptera is certain.
Velum or pre-oral (cephalic) lobe ever develops.
To the left of the gall bladder is the quadrate lobe, which is in contact with the pylorus of the stomach.
To the left of this is the left lobe of the liver, separated from the quadrate lobe by the umbilical fissure in which lies the round ligament of the liver, the remains of the umbilical vein of the foetus.
The posterior boundary of the quadrate lobe is the transverse fissure, which is little more than an inch long and more than half an inch wide.
Behind the transverse fissure the lower end of the Spigelian lobe is seen as a knob called the tuber papillare, and from tree right of this a narrow bridge runs forward and to the right to join the Spigelian lobe to the right Vena cava in its fossa lobe and to shut off the transverse fissure from that for the vena cava.
A similar fold passes from the tip of the left lobe as the left lateral ligament, and both these are the lateral margins of the coronary ligament.
When these have united the Spigelian lobe re of ductus venosus mental tuberosity ageal groove End of right suprarenal vein Suprarenal impression R; ght end of caudate lobe Uncovered area of right lobe Renal impression Attachment of right lateral ligament Fissu Portal fissure Umbilical fissure Quadrate lobe Portal vein Gall bladder Duodenal impression 0 Oesoph Cohc impressio; From A.
