Vertebrates

VERTEBRATES According to the molecular clock, a specific method for dating phylogenetic events, vertebrates (Vertebrata) separated from arthropods (Arthropoda) 976±97 Ma (2004HedgesSB_ShoeJL). The latter began to dominate in species diversity with the Cambrian burst of radiation, which occurred 520 Ma (2010EdgecombeGD). This ratio in the fauna of the Earth is still preserved. Approximately 525 Ma, the phylum Chordates separated from the group of bilaterally symmetrical animals (1995ChenJY_ZhouGQ). In turn, the evolution of chordate organisms led to the formation of the first vertebrates at least 500 Ma, from which the jawed mouths 450-400 Ma descended, becoming the ancestors of the placoderms or "armored" fish (Placodermi) (1979 НаумовНП _ КарташевНН ).

On the Role of the Ligamentum Capitis Femoris in the Maintenance of Different Types of Erect Posture S.V. Arkhipov Keywords: ligamentum capitis femoris, ligamentum teres, ligament of head of femur, abductor muscle group, role, function, hip joint, model, biomechanics, walk, gait cycle, single-legged stance ABSTRACT New experimental and clinical data on the function of the ligamentum capitis femoris (LCF) and its participation in maintaining an erect posture were obtained. It was established that this anatomical element is involved in constraining the hip joint adduction and may ﬁ x the joint in the frontal plane, turning it into an analogue of a second-class lever. In both unstrained one-support and asymmetrical two-support orthostatic postures, when the LCF is stretched and the abductor muscle group is exerted, a load equal to the body weight is evenly distributed between the upper and lower hemispheres of the caput femoris. In addition, the LCF fu...

Original in Russian is available at the link: Нижний портал. Часть 1. below is a machine translation edited by a non-native speaker ( version dated 03/02/2025 ) . INFERIOR PORTAL FOR HIP ARTHROSCOPY: A PILOT STUDY PART 1. Background and Hypothesis Arkhipov S.V., Independent Researcher, Joensuu, Finland Abstract: The article presents, theoretically and graphically substantiates the technique of a new arthroscopic approach to the central compartment of the hip joint. It is proposed to introduce the optical system of the arthroscope from below through the acetabular notch without traction. Similar approaches were used for puncture, arthroscopy, arthrography, and arthrotomy of the hip joint. Diagnostics using the described lower portal will exclude complications caused by distraction of the leg and compression of the perineal support during surgery. CONTENTS PART 1.
