Main Functions of LCF

Version: 20240419

MAIN FUNCTIONS OF LCF

1. Mechanical

2. Trophic

3. Sensory

4. Synthetic

5. Conductor

The mechanical function of LCF involves the ability to perform work, change the direction and magnitude of movements, and convert potential energy into kinetic energy, which manifests in effects. The mechanical function is realized by the stroma of LCF.

The trophic function of LCF involves providing nutrition and gas exchange in the medial part of the femoral head through the vascular system.

The sensory function of LCF involves synthesizing and transmitting information to the central nervous system about the magnitude of mechanical stresses in the stroma and attachment areas, as well as about the parameters of the intra-articular environment of the joint. The sensory function is provided by nerves and receptors of LCF, in conjunction with analyzers of the spinal cord and brain.

The synthetic function of LCF involves the production of synovial fluid, which reduces friction in the joint and participates in the nutrition and gas exchange of the articular cartilages. It is provided by the synovial membrane.

The conductor function of LCF involves supporting and directing nerves, blood vessels, and lymphatic vessels.

Effects of the Mechanical Function of LCF

1. Autolateralization effect

2. Autorotation effect

3. Autostabilization effect

4. Joint locking effect

Autorotation effect: rotation of the pelvis forward relative to the supporting leg.

Autostabilization effect: inclination of the pelvis forward and its adoption of a specific stable position in the sagittal plane.

Autolateralization rffect: pressing the acetabulum of the pelvis against the femoral head.

Joint locking effect: locking of the hip joint in the frontal plane and its transformation into an analogue of a second-class lever.

The effects of LCF are described in more detail in our dissertation research and abstract 2012ArkhipovSV (text, presentation).

ALTERNATIVE TYPES OF LCF FUNCTIONS

1. Physical

2. Biochemical

3. Biological

4. Informational

It is proposed to subdivide the functions of LCF into hierarchical units similar to the elements of the taxonomy of living organisms: type, order, family, genus, species. The identification of alternative functions is based on the participation of LCF in various processes occurring in the body: physical, chemical, biological, and informational.

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 ).

Fragment from the book Bauhin C. Theatrum anatomicum (1605). The author writes about the attachment, function, possible elongation and damage of the ligamentum capitis femoris (LCF). Lameness after dislocation is mentioned and its cause is explained. In the margins of the page are references to the works of other authors Vesalius , Laurens , Arch ang ( Archangelo Piccolomini ??? ) . Quote p. 1244. Liber IV.

50 TABLES OF EVIDENCE

Ancient Egypt is the birthplace of the Book of Genesis Arkhipov S.V. 50 Tables of Evidence for the Composition of Genesis in Late Second Intermediate Period Egypt: The Protograph Before the Oral Tradition. Joensuu : Author's Edition, 2026. GGKEY: ZPYTRNR69CB https://play.google.com/store/books/details?id=Dw7PEQAAQBAJ http://books.google.com/books/about?id=Dw7PEQAAQBAJ ASIN: B0GXWTLSLK https://www.amazon.com/dp/B0GXWTLSLK Synopsis This monograph presents a fundamental revision of the dating and origin of the Book of Genesis , challenging the dominant hypothesis, which dates the text to the mid-first millennium BCE. Through a systematic analysis presented in 50 comparative tables, the author argues that the protograph of Genesis was a deliberate literary compilation created in Egypt during the late Second Intermediate Period (ca. 17th–16th centuries BCE), shortly after the Minoan eruption. The core of the research concerns the non-oral origin of the text. By ident...
