Aortic arch5
The first aortic arch, on each side, is part of the primitive aorta, and is formed as the head fold is developed and the fore-gut is enclosed. (co.ma)
Vascular rings are formed when one or more aortic arch anomalies, with or without a patent ductus arteriosus or ligamentum, produce a ring that completely encircles the trachea and esophagus, leading to symptoms of tracheal or esophageal constriction. (musculoskeletalkey.com)
The remaining elements of the right aortic arch contribute to development of the right innominate artery and the primitive right subclavian artery. (musculoskeletalkey.com)
When regression of the left arch occurs between the left carotid artery and the left subclavian artery (left fourth primitive aortic arch), the latter arises from the descending aorta and courses posterior to the esophagus. (musculoskeletalkey.com)
A cervical aortic arch probably results from the persistence of the third primitive aortic arch, with regression of the contralateral arch between the carotid artery and the subclavian artery (fourth primitive arch). (musculoskeletalkey.com)
Vertebrates2
The broad picture," Yau says, "is that the local pupillary light reflex appeared early in primitive vertebrates such as jawless fish, even before the brain got involved. (jhu.edu)
The hindbrain is found in even the most primitive vertebrates. (medscape.com)
Cladistic analysis employing a range of primitive eutherian mammals shows that nyctitheres are stem euarchontans, rather than lipotyphlans, with which they had previously been classified based on dental characters. (palaeo-electronica.org)
Pseudomycelia vary in their complexity from very primitive, in which the numbers of cells are limited and where there is little or no differentiation among these cells, to other forms where cells comprising the main chain are rather elongated and the buds arise in clusters on the shoulder of these elongated stem cells. (biologydiscussion.com)
Tyrosine kinase inhibitors (TKIs) are very effective in treating chronic myelogenous leukemia (CML), but primitive, quiescent leukemia stem cells persist as a barrier to the cure. (bvsalud.org)
Tremors1
Before the etiology of Minamata disease was discovered, it plagued the residents around Minamata Bay in Japan with tremors, sensory loss, ataxia, and visual field constriction. (medscape.com)
Aorta1
The aortic arches are the vessels which connect the ventral portions of the primitive ventral aorta with the primitive dorsal aorta. (co.ma)
Prey2
They capable of expanding their jaws to a great extent, have palatal teeth, are large in size and kill their prey through the technique of constriction and suffocation. (animalsake.com)
They would have been similar to pythons , non-venomous and relying on constriction to kill their prey, although they had less flexible skulls than their modern relatives and couldn't easily swallow animals much larger than their own heads. (nixillustration.com)
Genus3
A new genus, Temperocastor, is proposed for E. valentinensis based on its primitive morphology of the cheek teeth and derived cranial morphology. (bioone.org)
Stirton ( 1935 ) viewed the phylogeny of this subfamily to be represented by the most primitive genus Monosaulax during the Barstovian, followed by the more derived Eucastor in the late Barstovian through the Clarendonian, which then gave rise to Dipoides in the Hemphillian. (bioone.org)
A few years earlier, Stehlin (1941) had classified his new genus Saturninia as a primitive member of the family Soricidae (shrews). (palaeo-electronica.org)
19971
Butler (1988), in his revision of the Lipotyphla, regarded the Nyctitheriidae as primitive soricomorphs, but McKenna and Bell (1997) returned the family to the Soricoidea. (palaeo-electronica.org)
Carcinoid1
Carcinoid tumors arise from neuroendocrine cells, which are widespread in the human body, especially in the organs derived from the primitive intestine (see the image below). (medscape.com)
Lateral2
The lateral margins of the primitive uro-genital opening give origin to the labia minora, and the genital eminence becomes the clitoris. (co.ma)
a sulcus which is formed on its cloacal aspect gradually becomes converted into a canal by the closure of the lateral lips of the primitive uro-genital opening. (co.ma)
Tongue2
The overarching goal is to understand the role of the 'mélange tongue' versus sub-shelf melting by ocean forcing in ice sheet stability by coupling a continuum model to simulate the ice flow, a particle model to simulate the breaking of ice and 'mélange tongue' processes and a primitive equation ocean model. (liu.se)
Can set off primitive reflexes such as the gag reflex or tongue thrust. (sunrisemedical.com.au)
Originating back in the mid-Cretaceous (~100 mya), these "primitive" snakes were found mostly in the southern continents of Gondwana (known from South America, Africa, India, and Australia), but a few also spread into Europe. (nixillustration.com)
Plants2
In primitive land plants, two additional unique classes of AQPs, GlpF-like intrinsic protein (GIPs) and hybrid intrinsic proteins (HIPs) have been described and are presumed to have been lost in the course of evolution [ 12 ]. (biomedcentral.com)
These "primitive" plants are living relics of some of the earliest vascular plants. (nynhp.org)
Mass1
For Burning Man, there are conceptions of markets and money, passivity and distance, individualism and selfishness, sexual repression and constriction, artificiality and mass culture, big corporations and oppressive religions to resist. (kozinets.net)
To me it was bizarre because I know that it will not be until settler Canadians stand up en masse to their government regarding Indigenous rights that anything will change. (lynngehl.com)
Could be caused by an overfull bladder (kinked catheter), an impacted bowel, a constriction of blood flow, a change in position, etc. (sunrisemedical.com.au)
Women1
And yet the triangular struggle between the two women has been so fierce and primitive, the terms of it finally so futile and empty, that we follow Ibsen right up to the mill bridge, even if we do not concede the plunge into the waters. (nybooks.com)
Multiple1
The power of primitivism as it occurs in multiple manifestations at Burning Man or within any other notions of the primitive is the power it yields in juxtaposition with other things. (kozinets.net)
Size1
A constriction and tightening of the body that causes shape and size changes, as well as texture changes to the breast. (happehtheory.com)
Wall1
They spring from the ventral aortæ or from the heart, they pass round the side walls of the fore-gut, in the branchial arches, and they terminate, in relation with the dorsal wall of the pharynx, in the primitive dorsal aortæ. (co.ma)
Dorsal6
The aortic arches are the vessels which connect the ventral portions of the primitive ventral aorta with the primitive dorsal aorta. (co.ma)
They spring from the ventral aortæ or from the heart, they pass round the side walls of the fore-gut, in the branchial arches, and they terminate, in relation with the dorsal wall of the pharynx, in the primitive dorsal aortæ. (co.ma)
It passes through the mandibular or first branchial arch, and connects the cephalic parts of the ventral and dorsal portions of the primitive aortæ together (Fig. 821). (co.ma)
In amniotes the elongation starts in the primitive streak stage, so that the body of the embryo is already long and narrow by the time the main axial organs (neural tube, notochord, dorsal mesoderm giving rise to the somites) are laid down. (notesonzoology.com)
The caudal end of the groove soon dilates into a pouch, and then the pouch and groove are separated by a constriction, which passes from the caudal towards the cranial end, from the more dorsal part of the fore-gut, which becomes the œsophagus. (co.ma)
Streak2
The bilaminar disc is divided axially by the primitive streak, at the apex of which is the primitive node. (medscape.com)
Invagination occurs along the primitive streak, giving the embryo (in cross-section) the appearance of an omega. (medscape.com)
Pharynx4
The portion of the wall of the primitive pharynx which lies between each pair of visceral arches and separates the clefts externally from the pouches internally is called the separating membrane. (co.ma)
The first pharyngeal pouch and the adjacent part of the cavity of the primitive pharynx becomes the tympanic cavity and the auditory (O.T. Eustachian) tube. (co.ma)
The third pharyngeal pouch opens like the first and second directly into the cavity of the fore-gut, but the fourth and fifth pouches lie in the lateral wall of a common recess which opens by a single aperture, the pharyngo-branchial duct, into the cavity of the primitive pharynx (Fig. 56). (co.ma)
The stalk of the diverticulum, which extends from what becomes the oral part of the primitive pharynx to the isthmus of the gland, is the thyreoglossal duct. (co.ma)
Ataxia2
Before the etiology of Minamata disease was discovered, it plagued the residents around Minamata Bay in Japan with tremors, sensory loss, ataxia, and visual field constriction. (medscape.com)
The scientific discoveries of health risks resulting from methylmercury exposure began in 1865 describing ataxia, dysarthria, constriction of visual fields, impaired hearing, and sensory disturbance as symptoms of fatal methylmercury poisoning. (nih.gov)
Ventral1
The diverticulum from the ventral wall of the primitive fore-gut, which is situated nearest the cephalic or anterior end of the gut, is the rudiment of the thyreoid gland. (co.ma)
Apex1
Bifurcation or trifurcation may be present only few millimetres above the root apex and pulp usually lacks constriction at cervical level of tooth. (dentalreach.today)
Visual1
To allow visual speech synthesis viseme primitives are identified from the corpus using automatic speech recognition. (surrey.ac.uk)
Body1
The only change that can happen to the ethereal body is constriction on the energy flow through its fibers (also called nadis). (drsmick.com)
State2
You whence more need constriction, state, fever and injured fomentations than a order needs valuable days. (clayalliance.org)
This isn't the result of vestigial genes that are normally "turned off" (as Giberson puts it) being accidentally turned back on when our development regresses to some primitive state. (evolutionnews.org)
Head1
The first aortic arch, on each side, is part of the primitive aorta, and is formed as the head fold is developed and the fore-gut is enclosed. (co.ma)
Layers1
Epiblast cells pour into the primitive node, converting the bilaminar disc into a disk with three germ cell layers. (medscape.com)
Origin1
Modesty therefore is highly conventional, and to discover its origin the most primitive tribes must be observed. (wikisource.org)
