Skeletal Muscle Contraction

Summary
Skeletal Muscle Contraction
is a complex
Physiological process
initiated by the
Nervous System
, where an
Action Potential
triggers the
Release of calcium ions
, leading to the
Sliding of actin and myosin filaments
and resulting in
Muscle shortening
. This process is highly regulated by the
Troponin-Tropomyosin Complex
and requires ATP for both
Contraction and relaxation phases
.
