The anterior cruciate ligament consists of two bundles, the anteromedial and posterolateral which are frequently associated with meniscal dysfunction. Despite previous studies investigating relationship between biomechanical instability injury, a comprehensive histological analysis anatomical aspects contributing to injury degenerative changes structural connectivity meniscus is lacking. Masson's trichrome, pentachrome, Safranin-O, modified Verhoeff-Van Gieson stains microcomputed tomography...

Abstract The sacrotuberous ligament (STL) and the hamstrings are important structures that mutually connected influenced by pelvis. However, anatomical connectivity histological characteristics of these remain unclear. present study aimed to comprehensively investigate relationship between STL proximal through analysis. Sixteen specimens were obtained from eight fresh cadavers (mean age at death, 73.4 years). Verhoeff Van Gieson, Masson's trichrome, immunohistochemical staining used analyze...

Combined suprascapular and axillary nerve block could be an analgesic option for shoulder pain control. The current description of this technique requires performing the procedures at two different sites without consideration catheter placement. We hypothesized that a single site injection to interfascial plane between infraspinatus teres minor would result in injectate spread nerves.

The frontal sinus is one of the four paranasal sinuses in humans, and knowledge its anatomy important when performing surgery involving bone or sinus. Although many studies have measured using radiography computed tomography (CT), few evaluated by three-dimensional (3D) analysis. purpose this study was to analyze 3D reconstruction analysis determine differences linear volumetric measurements between sexes, sides, ages. sample comprised 281 facial CT scans: 173 108 from males females,...

The present study is to identify primarily the morphological characteristics in growth proportion of head and face for young Korean (8-24 years) compare magnitude changes sex-related differences. Total 1255 were divided into 3 age groups: childhood (8-10 years), adolescence (14-16 adult (20-24 years). anthropometric assessments performed with 11 landmarks on facial dimensions. standardized frontal lateral photographs analyzed craniofacial proportions features comparison both sexes....

The facial artery is the main supplying blood to face and known have branches of inferior labial, superior lateral nasal angular arteries. These major run medially, however, there are sometimes heading laterally. purpose present study was investigate in face. We dissected 74 cadaveric hemifaces. investigated presence artery. Following parameters were investigated: branch presence, location its origin, diameter. Among branches, we evaluated prevalence diameter premasseteric branch. Lateral...

<title>Abstract</title> Adult neurogenesis may help overcome Alzheimer’s disease; however, knowledge concerning neurogenic markers in the human brain remains limited. Herein, we compared hippocampal single-nucleus transcriptome to other cortical regions verify exclusive dentate gyrus. We analyzed 26,189 of 40,691 nuclei initially extracted from four brains within 16 hours death. Analyses were performed after clustering and annotation elucidate differential expression, gene ontology,...

Introduction: Neurogenesis in the adult brain may play an important role memory and cognition; however, knowledge of neurogenic markers human remains limited. We compared single-nucleus transcriptome hippocampus with that other cortical regions to identify hippocampus-specific markers. Methods: analyzed 26,189 nuclei from four brains collected within 16 h death. Clustering annotation were performed examine differential expression, gene ontology, intercellular communication. DCX expression...

<title>Abstract</title> Purpose The tibialis posterior (TP), flexor digitorum longus (FDL), and hallucis (FHL) are muscles that contribute to the stability of foot ankle movements, playing a crucial role in achieving optimal gait. However, comprehensive examination anatomical characteristics histological variances each muscle has not been conclusively established. Methods A total 10 un-embalmed cadavers were dissected, from cadaver consistently harvested musculotendon junction. ratio...

Accessory nerve (CNXI) has been known to be the primary conduit for motor control of trapezius, while supplementary cervical nerves (C3 and C4) are responsible processing sensory information from muscle. However, lack substantial direct evidence led these conclusions being regarded as mere speculation. This study used immunostaining (using antibodies against neurofilament 200 all axons, choline acetyltransferase cholinergic tyrosine hydroxylase sympathetic alpha 3 sodium potassium ATPase...

The aims of this study were to clarify the extra- and intramuscular branching patterns tensor fasciae latae (TFL) with reference surface landmarks on thigh thus suggest a safe approach for total hip arthroplasty. Sixteen fixed four fresh cadavers dissected subjected modified Sihler's staining method reveal innervation patterns, findings matched landmarks. measured from anterior superior iliac spine (ASIS) patella divided into 20 parts along length. average vertical length TFL was 15.92 ±...

The elevator muscles of the upper lip are levator labii superioris alaeque nasi, superioris, and zygomaticus minor muscles, which function by means their insertions into skin lip. However, many textbooks journal articles state that no muscle fibers present on orbicularis oris in authors attempted to determine whether there is a superficial layer addition lip.The performed gross dissections 10 formalin-fixed cadavers applied micro-computed tomography six cadavers. fine dissection was...

Abstract The seminal vesicles are the glands of male reproductive organs that produce fluid and nutrient constituents semen. It has been believed for a long time lumen vesicle was single‐coiled tubular structure with irregular diverticula. There several previous reports on symmetry, differences in morphological sizes classification vesicles. However, three‐dimensional‐coiled is difficult to understand using classical anatomical methodology, hence, three‐dimensional reconstruction needed...

The zygomatico-orbital artery (ZOA) originating from the superficial temporal and supplying lower region superficially has been reported. Previous studies of this have used definitions that are too ambiguous for results to be directly adapted clinical practice, including since they resulted in marked variations reported incidence ofthe artery. This study dissected 193 hemifaces 123 fixed human cadavers aged 36 102 years (119 males 74 females). authors investigated ZOA based on following...

Abstract This present study was designed to visualize the superior laryngeal nerve (SLN) space and investigate spreading patterns of agent in SLN using three-dimensional (3D) micro-computed tomography (CT), histologic study, cadaveric evaluation. Thirteen non-embalmed human cadavers were used this study. Micro-CT images larynx surrounding structures obtained, 3D reconstructed. The structure verified via histological examination manual dissection. To evaluate anatomical findings, 1 3 mL dye...
