Studies of Human Physique and Sexual Attractiveness: Sexual Preferences of Men and Women in China
AMERICAN JOURNAL OF HUMAN BIOLOGY 19:88–95 (2007) Original Research Article Studies of Human Physique and Sexual Attractiveness: Sexual Preferences of Men and Women in China 1 2 3 1 BARNABY J. DIXSON, ALAN F. DIXSON, * BAOGUO LI, AND M.J. ANDERSON 1Department of Conservation and Research for Endangered Species, Zoological Society of San Diego, San Diego, California 2School of Biological Sciences, Victoria University of Wellington, Wellington, New Zealand 3College of Life Sciences, and Key Laboratory Resource Biology and Biotechnology in Western China, Ministry of Education, Northwest University, Xi’an, China ABSTRACT Men and women at Northwest University (n ¼ 631), Xi’an, China, were asked to rate the attractiveness of male or female figures manipulated to vary somatotype, waist-to- hip ratio (WHR), secondary sexual traits, and other features. In study 1, women rated the aver- age masculine somatotype as most attractive, followed by the mesomorphic (muscular), ecto- morphic (slim), and endomorphic (heavily built) somatotypes, in descending order of preference. In study 2, the amount and distribution of masculine trunk (chest and abdominal) hair were altered progressively in a series of front-posed figures. Women rated figures with no or little trunk hair as most attractive. Study 3 assessed the attractiveness of front-posed male figures which varied only in length of their nonerect penis. Numerical ratings for this trait were low, but moderate lengthening of the penis (22% or 33% above average) resulted in a significant increase in scores for attractiveness. In study 4, Chinese men rated the attractiveness of back- posed female images varying in waist-to-hip ratio (WHR from 0.5–1.0). -

MR Imaging of Vaginal Morphology, Paravaginal Attachments and Ligaments
MR imaging of vaginal morph:ingynious 05/06/15 10:09 Pagina 53 Original article MR imaging of vaginal morphology, paravaginal attachments and ligaments. Normal features VITTORIO PILONI Iniziativa Medica, Diagnostic Imaging Centre, Monselice (Padova), Italy Abstract: Aim: To define the MR appearance of the intact vaginal and paravaginal anatomy. Method: the pelvic MR examinations achieved with external coil of 25 nulliparous women (group A), mean age 31.3 range 28-35 years without pelvic floor dysfunctions, were compared with those of 8 women who had cesarean delivery (group B), mean age 34.1 range 31-40 years, for evidence of (a) vaginal morphology, length and axis inclination; (b) perineal body’s position with respect to the hymen plane; and (c) visibility of paravaginal attachments and lig- aments. Results: in both groups, axial MR images showed that the upper vagina had an horizontal, linear shape in over 91%; the middle vagi- na an H-shape or W-shape in 74% and 26%, respectively; and the lower vagina a U-shape in 82% of cases. Vaginal length, axis inclination and distance of perineal body to the hymen were not significantly different between the two groups (mean ± SD 77.3 ± 3.2 mm vs 74.3 ± 5.2 mm; 70.1 ± 4.8 degrees vs 74.04 ± 1.6 degrees; and +3.2 ± 2.4 mm vs + 2.4 ± 1.8 mm, in group A and B, respectively, P > 0.05). Overall, the lower third vaginal morphology was the less easily identifiable structure (visibility score, 2); the uterosacral ligaments and the parau- rethral ligaments were the most frequently depicted attachments (visibility score, 3 and 4, respectively); the distance of the perineal body to the hymen was the most consistent reference landmark (mean +3 mm, range -2 to + 5 mm, visibility score 4). -

Six days after the radiofrequency procedure, she noticed a facial asymmetry during smiling. Physical examination revealed immobility of the mouth drawing upward and laterally on the left. Routine nerve conduction studies and needle electromyography (EMG) in facial muscles did not suggest electrodiagnostic abnormalities. We assumed that the cause of facial asymmetry could be due to an injury of zygomaticus muscles, however, since defining the muscles through surface anatomy was difficult and it was not possible to identify the muscles with conventional electromyographic methods. Sono-guided needle EMG for zygomaticus muscle revealed spontaneous activities at rest and small amplitude motor unit potentials with reduced recruitment patterns on volition. Sono-guided needle EMG may be an optimal approach in focal facial nerve branch injury for the specific localization of the injury lesion.

The Anatomy, Biological Plausibility and Efficacy of Visceral Mobilization in the Treatment of Pelvic floor Dysfunction
Journal of Pelvic, Obstetric and Gynaecological Physiotherapy, Autumn 2015, 117, 5–18 CLINICAL REVIEW The anatomy, biological plausibility and efficacy of visceral mobilization in the treatment of pelvic floor dysfunction R. C. Horton Rehabilitation Services, Asante Rogue Regional Medical Center, Medford, Oregon, and Faculty, Herman & Wallace Pelvic Rehabilitation Institute, Seattle, Washington, USA Abstract This paper provides an overview of the technique of visceral mobilization. Founded on the principles of osteopathic manipulative therapy, this modality is employed by manual therapy practitioners throughout the world. Advancements in the field of pelvic physiotherapy have generated a better understanding of how the components of the abdominopelvic canister work synergistically to support the midline of the body and contribute to normal function. The walls of this canister are occupied by and intimately connected to the visceral structures found within the abdominal cavity. These midline contents carry a significant mass within the body, and affect the function of the somatic frame in three ways: referred visceral pain; central sensitization; and changes in local tissue dynamics. The evidence supporting visceral mobilization therapy (VMT) is limited, and there is an overabundance of case reports and observational studies in the literature. How- ever, there is some higher-level clinical evidence that supports the inclusion of VMT within a comprehensive treatment programme for a number of pelvic physiotherapy diagnoses, including lower urinary tract dysfunction, chronic constipation and irritable bowel syndrome. The evidence supporting VMT for the treatment of adhesion-related disorders such as infertility shows promise, and further studies are currently in progress. Keywords: fascia, manual therapy, osteopathy, pelvic dysfunction, visceral mobilization. -
Atlas of the Facial Nerve and Related Structures
Rhoton Yoshioka Atlas of the Facial Nerve Unique Atlas Opens Window and Related Structures Into Facial Nerve Anatomy… Atlas of the Facial Nerve and Related Structures and Related Nerve Facial of the Atlas “His meticulous methods of anatomical dissection and microsurgical techniques helped transform the primitive specialty of neurosurgery into the magnificent surgical discipline that it is today.”— Nobutaka Yoshioka American Association of Neurological Surgeons. Albert L. Rhoton, Jr. Nobutaka Yoshioka, MD, PhD and Albert L. Rhoton, Jr., MD have created an anatomical atlas of astounding precision. An unparalleled teaching tool, this atlas opens a unique window into the anatomical intricacies of complex facial nerves and related structures. An internationally renowned author, educator, brain anatomist, and neurosurgeon, Dr. Rhoton is regarded by colleagues as one of the fathers of modern microscopic neurosurgery. Dr. Yoshioka, an esteemed craniofacial reconstructive surgeon in Japan, mastered this precise dissection technique while undertaking a fellowship at Dr. Rhoton’s microanatomy lab, writing in the preface that within such precision images lies potential for surgical innovation. Special Features • Exquisite color photographs, prepared from carefully dissected latex injected cadavers, reveal anatomy layer by layer with remarkable detail and clarity • An added highlight, 3-D versions of these extraordinary images, are available online in the Thieme MediaCenter • Major sections include intracranial region and skull, upper facial and midfacial region, and lower facial and posterolateral neck region Organized by region, each layered dissection elucidates specific nerves and structures with pinpoint accuracy, providing the clinician with in-depth anatomical insights. Precise clinical explanations accompany each photograph. In tandem, the images and text provide an excellent foundation for understanding the nerves and structures impacted by neurosurgical-related pathologies as well as other conditions and injuries. -
