Abstract Horses revolutionized human history with fast mobility 1 . However, the timeline between their domestication and widespread integration as a means of transport remains contentious 2–4 Here we assemble collection 475 ancient horse genomes to assess period when these animals were first reshaped by agency in Eurasia. We find that reproductive control modern domestic lineage emerged around 2200 bce , through close-kin mating shortened generation times. Reproductive following severe...
Summary This study was undertaken to evaluate the flexion‐extension movements of back in a group sound trotting horses. Using 3‐D kinematic analysis system, 13 clinically horses fitted with 5 skin markers placed on dorsal midline their trunk were recorded while track conditions routine lameness examination. These used calculate 3 angles (thoracic, thoracolumbar and lumbosacral angle). then filtered using Fourier series. To repeatability movements, intra‐ inter‐individual variabilities...
Comprehensive understanding of the 3-dimensional (3D) kinematics distal forelimb and precise knowledge alterations induced by dorsopalmar foot imbalance remains incomplete because in vivo studies performed with skin markers do not measure actual movements 3 digital joints.To quantify effects 6 degree heel or toe wedges on 3D 4 segments horses trotting a treadmill.Three healthy were equipped ultrasonic fixed surgically to left forelimb.

Abstract Objective —To develop a method that allows quantification of the 3 anatomic rotations in digital joints moving horses and measure these when are walking straight line on hard track. Animals —4 healthy French Trotter horses. Procedure —Triads ultrasonic kinematic markers were surgically linked to 4 distal segments digits left forelimb each horse. Three-dimensional (3-D) coordinates recorded line. The three angles rotation joint calculated by use coordinate system as well 3-D...
Summary Reasons for performing study : Sharp turns are suspected to increase expression of several distal forelimb lamenesses even at the walk but biomechanical consequences such a movement remain unknown. Objective To quantify effects sharp turn on 3‐dimensional movements segments forelimb. Methods Kinematics were measured in 4 healthy horses invasively with an ultrasonic system. Three‐dimensional rotations digital joints calculated by use joint coordinate Data obtained compared those...
Twenty‐two magnetic resonance imaging (MRI) brain studies of different breeds dogs were reviewed to assess the anatomy cranial nerve (CN) origins and associated skull foramina. These included five anatomic normal brains using 2‐mm‐thick slices 17 conventional clinical protocols with 3‐ or 4‐mm on both abnormal brains. Images obtained in transverse, sagittal, dorsal planes allow a thorough comparison between studies. CNs II, III, V (and its divisions), VIII observed consistently On thin‐slice...
The purpose of this study was to demonstrate the feasibility surface electromyography in horse and correlate electromyographic activity with kinematic data. Surface seven hindlimb muscles recorded five horses at trot on a treadmill. Simultaneously, analysis performed using three-dimensional system unidirectional accelerometer attached hoof.

Kinematics was measured invasively a system based ultrasonic triangulation. Three‐dimensional rotations joints calculated by use ‘joint coordinate...
Magnetic resonance (MR) images of the brain four normal cats were reviewed retrospectively to assess emergence and course cranial nerves (CNs). Two-millimeter-thick obtained in transverse, sagittal, dorsal planes using a 1.5 T unit. CN skull foramina, as anatomic landmarks for MR imaging, identified by computed tomography performed on an isolated cat thin wire within each foramen. Thin slice (1 mm thickness) with high-resolution bone filter scan protocol. The origins CNs II, V, VII, VIII...
Summary This study was undertaken to describe the symmetry of movements fore‐ and hindlimbs in horses suffering from various spontaneous lamenesses. Two groups were studied: 13 clinically sound 24 lame horses. Using a 3‐dimensional (3‐D) kinematic analysis system, both sides each horse recorded simultaneously while trotting on track. The differences motion between left right homologous joints quantified using indices based an intercorrelation method. Symmetry obtained for then compared with...
