3. CCA Aplasia. A research of the cause of the CCA absence was the topic of many works over the centuries. Macalister in [] has noted that a persistence of the DC and an obliteration of the transverse part of the third PAA cause the ICA to arise independently from the opinion was supported 50 years later by the facts that no carotid sinus nor sinus nerve were presented, Author: L.

Vasović, M. Trandafilović, S. Vlajković. In mammalian species, the carotid body is localized in the carotid bifurcation and innervated by the carotid sinus nerve consisting of sensory fibers from the glossopharyngeal nerve.

However, I later decided to place the entire page under the Yun Peng Huang Collection umbrella, both to highlight the contribution of Dr.

Huang and his colleagues to the small body of venous embryologic knowledge, and to place their work in appropriate and clinically-relevant context.

The head and neck is not really a "system", but structurally quite different in origin from the body. The head and neck are one of the most complicated structures that the embryo forms, with special intermediate structures (the pharyngeal arch) and contributions from all 3 embryonic layers (ectoderm, mesoderm, endoderm), and significantly, a major contribution from the neural crest.

The cranial cervical ganglion (CCG), which is a paravertebral cervical sympathetic ganglion, is the site of the cell bodies for all postganglionic neurons innervating the target organs of the head and high cervical levels (Jenkins, ).Although gross anatomical studies on the CCG and its branches have been described in detail on cats (Billingsley and Ranson, ), dogs (Mizeres, Cited by: 1.

In an attempt to describe the morphofunctional consequences of uni- and bilateral aplasia of the common carotid artery (CCA), which is usually a vascular source of the external carotid (ECA) and internal carotid (ICA) arteries, we investigated online databases of anatomical and clinical papers published from the 18th century to the present : L.

Vasović, M. Trandafilović, S. Vlajković. Carotid body (CB) chemoreceptors transduce low arterial O2 tension into increased action potential activity on the carotid sinus nerves, which contributes to resting ventilatory drive, increased.

From a developmental point of view, several considerations apply. To understand the developmental background of SS and its contribution to the morphology and embryology of the carotid sinus and the carotid body book malformations, first the relevant processes in embryonic development will be described.

These comprise the formation of the embryonic germ layers, including the splanchnic mesoderm with the cardiac, lung, and early vascular plexus formation.

Keywords: sphenoid sinus, endoscopic sinus surgery, internal carotid artery, optic nerve. Development of the sphenoid sinus Current theories consider that the skull base originates predominately from cartilaginous precursors with a small contribution from membranous bone [1, 2].

The sphenoid bone consists of the body, the lesser and. The left sinus horn regresses and persists as the main vein of the heart, the coronary sinus, whose valve arises from the inferior part of the right venous valve.

The right sinus horn is incorporated into the right atrium, where it forms the smooth-walled part. The portal vein does not send blood to the sinus. The last final fibers terminate to give rise to the nerve to the carotid sinus, or Hering’s nerve, which carries visceral afferent innervation from the carotid baroreceptors.

When de Castro entered the carotid body (CB) field, the organ was considered to be a small autonomic ganglion, a gland, a glomus or glomerulus, or a paraganglion. In his paper, de Castro concluded: “In sum, the Glomus caroticum is innervated by centripetal fibers, whose trophic centers are located in the sensory ganglia of the glossopharyngeal, and not by centrifugal [efferent] or Cited by: 9.

In the first part of the study, de Castro develops the idea of the carotid sinus baroreceptor reflex as described by Hering and describes experiments on the structure and innervation of the carotid sinus area in several mammalian species giving full support to the notion that the origin of the reflex is the carotid sinus and its profuse Cited by: 9.

Kevin Coward and Dagan Wells. The third PAA becomes the carotid sinus, and with the cranial DA forms the internal carotid artery (ICA), while the cranial ventral aorta becomes the ECA [7].

However, the root of the ECA can originate only from the proximal portion of the third PAA, which normally becomes the CCA [3].

The ninth edition of Langman’s Medical Embryology adheres to the tradition established by the original publication—it provides a concise but thorough description of embryology and its clinical. Aim of the course is to present basic chemical and physical properties of Dental materials as they are related to its manipulation to give a sound educational background so that the practice of the dentistry emerged from art to empirical status of science as more information through further research becomes available.

Abstract. The modern or living reptiles comprise four different orders: the Chelonia (turtles), the Rhynchocephalia (the tuatara, Sphenodon, from New Zealand), the Squamata (amphisbaenians, lizards and snakes) and the Crocodilia (alligators and crocodiles).Reptiles, birds and mammals together form the amniotes and are distinguished from amphibians by the evolution of a reproductive pattern.

What causes heart disease. We, Homo sapiens, cause heart disease by living and eating in a manner that is alien to our history. By ignorance or choice many of us consume foods that are a poor source of the nutrients we need to provide health and typically promote ill health.

Valvular heart disease (VHD) is frequent is industrialized countries and its prevalence increases with age due to the predominance of degenerative aetiology. Clinical approach is paramount for evaluation of the patient’s history, symptoms and for the detection of VHD by auscultation.

Echocardiography plays a major role in diagnosis and assessment of severity and : Bernard Iung. Embryology provides an understanding of the process by which the human body develops.

The study of embryology is essential for understanding topographical relationships in gross anatomy, and for. The morphology of the cranial endocast of Pawpawsaurus is, in general, similar to that described for other ankylosaurs [9–11, 13–17], being anteroposteriorly short and having a globose forebrain and enlarged internal carotid arteries that transversely enter the distal end of the pituitary fossa (except in Kunbarrasaurus).

Mitral regurgitation is the second most frequent indication for valve surgery in Europe. Echocardiography is essential to assess the aetiology of mitral regurgitation, as well as valve anatomy and function.

An integrative approach is needed to assess the severity of mitral regurgitation. Indication for intervention in primary mitral regurgitation is guided by symptoms and risk stratification Author: Raphael Rosenhek.

The baroreceptors are densely situated on the walls of the arch of aorta and the carotid sinus. The carotid sinus is present on the base of internal carotid artery at the level of bifurcation of the common carotid artery. The sinus area is slightly dilated as the tunica media which is normally comprised of muscles, is relatively thin.

Results: These combined anatomical methods successfully visualized bony landmarks, vessels (e.g. sinus cavernosus, internal carotid artery, Willis‐circle), nerves (trigeminus, abducens, oculomotorius, trochlearis) and pituitary gland in the middle cranial fossa.

We also performed a successful transsphenoidal brain surgery on a dog who had a. This book is the first significant contribution to thoroughly examine the potential hazards associated with snakes of the former family, Colubridae. This family contained >65% of living snake species (approximately 3, taxa) and has recently been split into multiple families.
