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.
