Systole heart beats—is cued by messages from the brain, reflecting the brain's responses to conditions of the body, such as pain, emotional stress, level of activity, and to ambient conditions including external temperature, time of day, etc. Electrical systole opens voltage-gated sodium, potassium and calcium channels in cells of myocardium tissue. Subsequently, a rise in intracellular calcium triggers the interaction of actin and myosin in the presence of ATP which generates mechanical force in the cells in the form of muscular contraction, or mechanical systole. The contractions generate intra-ventricular pressure, which is increased until it exceeds the external, residual pressures in
Facial Autologous Muscular Injection Facial Autologous Muscular Injection Facial Autologous Muscular Injection is also known as Fat Autograft Muscular Injection, as Autologous Fat Injection, as Micro-lipoinjection, as Fat Transfer and as Facial Autologous Mesenchymal Integration, abbreviated as FAMI. The technique is a non-incisional pan-facial rejuvenation procedure using the patient'own stem cells from fat deposits. FAMI is an Adult stem cell procedure used to address the loss of volume in the face due to aging or surgery repair in restoring facial muscles, bone surfaces and very deep fat pads. The procedure involves removing adult stem cells of fatty tissue from lower body, and refining it
