Pre-clinical anatomy curricula must provide medical students with the knowledge needed in a variety of and surgical specialties. But do physicians within specialties agree about what anatomical is most important their practices? And, common core deemed essential by different specialties? Answers to these questions would be useful designing pre-clinical courses. The primary aim this study was assess importance human gross course soliciting opinions from range We surveyed 93 determine specific...
ABSTRACT The tradeoff between force and velocity in skeletal muscle is a fundamental constraint on vertebrate musculoskeletal design (form:function relationships). Understanding how why different lineages address this biomechanical problem an important goal of functional morphology. Our ability to answer questions about the solutions has been significantly improved by recent advances techniques for quantifying morphology movement. Herein, we have three objectives: (1) review morphological...
Abstract During swallowing, a diverse range of mammals — from opossums to humans propel food boluses out the oropharynx via tongue base retraction (TBR). The widespread distribution TBR behavior implies an ancient evolutionary origin, but biomechanical mechanisms remain poorly understood. evolution is further complicated by diversity hyoid and anatomy across mammals: what extent does hyolingual morphology shape mechanism? Using biplanar videoradiography XROMM workflow, we collected...
During primate swallowing, tongue base retraction (TBR) drives the food bolus across oropharynx towards esophagus and flips epiglottis over laryngeal inlet, protecting against penetration aspiration of into airway. Despite importance TBR for swallowing performance, mechanics are poorly understood. Using biplanar videoradiography (XROMM) four macaque monkeys, we tested extrinsic muscle shortening hypothesis, which posits that hyoglossus styloglossus muscles pulls posteriorly, muscular...
Three-dimensional (3D) tongue movements are central to performance of feeding functions by mammals and other tetrapods, but 3D kinematics during poorly understood. Tongue were recorded grape chewing macaque primates using biplanar videoradiography. Complex shape changes in the dominated a combination flexion tongue's sagittal planes roll about its long axis. As hypothesized for humans, macaques retraction, middle (molar region) rolls (working) side simultaneous with flexion, while tip flexes...
Abstract The organization of tissues in appendages often affects their mechanical properties and function. In the fish family Labridae, swimming behavior is associated with pectoral fin flexural stiffness morphology, where fins range on a continuum from stiff to relatively flexible fins. Across this diversity, decreases exponentially along length any given ray, ray chord leading trailing edge. study, we examine morphological rays, including effective modulus bending ( E ), second moment area...
Introduction: Stereolithography, also known as 3D printing (3DP), is a versatile and useful technology with many healthcare applications. While 3DP has gained tremendous popularity, it remains daunting perceptibly time-consuming process for the inexperienced user, most turning to commercially printed products. Commercial vendors are expensive. We propose that feasible user appropriate knowledge tools. Methods: A protocol was created model design using open-source software low-cost desktop...
Sarcomere lengths are widely used to calculate scaled sarcomere models of whole muscle length‐tension curves. Previous studies have shown that fresh tissues accurately predict experimental Diffusible iodine‐based contrast enhanced CT (diceCT) imaging employs iodine staining with Lugol's solution (I 2 KI) improve visualization tissue the level individual fascicles, which holds great promise allow modeling multiple muscles. However, skeletal muscles I KI causes significant volumetric shrinkage...
The primate hyolingual apparatus is a complex composite of muscular hydrostat and floating bone that essential for feeding. In particular, the characteristic elevation (i.e., “squeeze‐back” mechanism) retraction tongue base during swallowing may be important in flipping epiglottis to protect laryngeal inlet. However, link between muscle behavior kinematics poorly supported by vivo data. Tongue could due one or combination three mechanisms thanks its redundant morphology: intrinsic muscles...
The macaque ( Macaca mulatta ) is a promising model organism for the integrated study of neurological and biomechanical basis human feeding disorders. However, while behavior has been extensively studied in macaque, we have limited knowledge about its three‐dimensional hyolingual myoarchitecture, especially intrinsic musculature tongue. This preliminary reports results digital dissection utilizing radiopaque staining techniques micro‐computed tomography. A 1:1 solution 5% Lugols 190 proof...
A competency‐based, pre‐clinical anatomy curriculum must provide medical students with the knowledge needed in a variety of and surgical specialties, such is typically assessed through testing. While conventional testing methods give general sense whether student understood material, they are often unable to determine specific strengths or weaknesses both curriculum. For example, one would not know pass exams by satisfactorily understanding all as opposed ignoring some portion it but...
