Connections between postparotid terminal branches of the facial nerve: An immunohistochemistry study.

It has been assumed that connections between the postparotid terminal branches of the facial nerve are purely motor. However, the nature of their fibers remains unexplored. The aim of this study is to determine whether these connections comprise motor fibers exclusively.

The incidence and shape of the digital pulleys: a study of 192 fingers in 48 cadaveric hands.

We dissected 192 fingers in 48 fresh cadaveric hands (23 right and 25 left hands from 26 female and 22 male donors) and analysed the incidence, location, length and structure of the five annular and three cruciform pulleys. No statistically significant differences were found between left and right or between male and female hands. The A1, A2 and A4 pulleys were present in all fingers, while the incidence of other pulleys varied.

Anatomic mapping of the collateral branches of the external carotid artery with regard to daily clinical practice.

Background: To identify the anatomical variations of the main branches of the external carotid artery (lingual, facial, occipital, ascending pharyngeal and sternocleidomastoid), giving information about the calibers and origins with the aim of creating a new classification useful in clinical practice.

Material And Methods: 193 human embalmed body-donors were dissected. The data collected were analyzed using the Chi² test.

Comparative anatomo-radiological study of intrahepatic venous vascularization in the Spain.

Background: Anatomic variations in the hepatic venous system are the least understood aspect of hepatic anatomy. The variations are diverse, and data are lacking with respect to the population of Spain and methods of detection. The objective was to examine morphological patterns of variations in hepatic venous vascularization using cadaveric dissections vs.

Body Donation, Teaching, and Research in Dissection Rooms in Spain in Times of Covid-19.

The state of alarm due to Covid-19 pandemic in Spain stopped all educational and most university research activities. The Spanish Anatomical Society (SAE) Consensus Expert Group on Body Donations piloted a study based on a questionnaire to know the status of body donations and dissection activities during the lockdown, as well as the future implications of Covid-19 pandemic for body donation programs and anatomy teaching. The questionnaire results show that Spanish Universities refused body donations and stopped all dissection research and teaching.

Network analysis: An indispensable tool for curricula design. A real case-study of the degree on mathematics at the URJC in Spain.

Content addition to courses and its subsequent correct sequencing in a study plan or curricula design context determine the success (and, in some cases, the failure) of such study plan in the acquisition of knowledge by students. In this work, we propose a decision model to guide curricular design committees in the tasks of course selection and sequencing in higher education contexts using a novel methodology based on network analysis. In this work, the local and global properties stemming from complex network analysis tools are studied in detail to facilitate the design of the study plan and to ensure its coherence by detecting the communities within a graph, and the local and global centrality of the courses and their dependencies are analyzed, as well as the overlapping subgroups and the functions and different positions among them.

Extracranial Course of the Facial Nerve Revisited.

Introduction: The extrapetrous course of the facial nerve has been a matter of study and debate since XIX century. Two different classifications have been classically proposed and widely accepted by most of the authors. Nevertheless, there are reported cases which do not fit in any of those.

Arthroscopic Scapholunate Ligament Reconstruction, Volar and Dorsal Reconstruction.

Arthroscopic scapholunate volar and dorsal ligament reconstruction achieves an anatomic reconstruction, avoids an open approach and capsular detachment, and provides a strong construct for early mobilization. Clinical results are discussed. Detailed "surgical tips" and technical modifications are provided.
