| Extraocular muscles are important references in strabismus surgery and in placement of intraorbital devices. We analyzed extraocular muscles morphometry and possible anatomical variances of 20 orbits. We report the length, width, and points of insertion of the extraocular muscles. No anatomical variations in length, width and points of insertion were found. With regard to the rectus muscles, it was found that the superior rectus and lateral rectus are the longest muscles and that the width difference between the superior and inferior rectus is greater than that between the medial and lateral rectus and that the point of insertion of the rectus muscles has a variable morphology. The superior oblique muscle was smaller in caliber than the inferior oblique,... |

| Las arterias más importantes de la mano son la radial y ulnar, las que forman los arcos palmares superficial y profundo. La descripción detallada de las características anatómicas de los arcos palmares ha contribuido al desarrollo de nuevas técnicas microquirurgicas en la mano. Los objetivos de este estudio fueron establecer el patrón arterial de la mano, así como determinar el diámetro luminal de las arterias que contribuyen a la formación de los arcos. Se realizó un estudio descriptivo, utilizándose 25 manos de cadáveres embalsamados. Se seccionaron las arterias en diferentes puntos para su tinción y observación al microscopio de luz. El arco palmar superficial completo fue observado en 14 (56%) muestras y en 11 (44%) se presentó de manera incompleta. El... |

| Knowing the dimensions of the vertebral elements is very important for the development of instrumentation related to the cervical spine. Ethnic variations have been reported in these dimensions and, to date, there have been no morphometric studies of this area performed on the Mexican population. We conducted a morphometric study of 150 cervical vertebrae (C3-C7) obtained from a northeastern Mexican population to determine the dimensions of the bodies, pedicles, laminae, spinous processes, and superior and inferior articular processes. We did not find significant differences (p<0.05) in measurements taken of the left and right sides. The dimensions of the vertebral bodies were larger at lower levels. The pedicles of the C3 vertebra were larger in all... |
