Abstract:
Functioning free muscle transfer to the upper extremity is an extremely complex and difficult procedure. It is useful only in selected cases that require significant skeletal muscle replacement and fulfill stringent criteria. The operation itself is performed by means of a two-team approach. Attention to detail is paramount if success is to be achieved. Careful placement of the muscle origin and insertion under appropriate tension is a key feature of the procedure. Precise microvascular anastomoses and microneural coaptations must be done. A time-intensive rehabilitation program is needed to gain as much function from the muscle as possible. Although not perfect, free muscle transfer does provide substantial improvement from a functional standpoint for these unfortunate patients.

Muscle Coordination and Action
Agonists
Agonist muscles, often called prime movers, are the primary muscles responsible for producing a specific movement.
Motor Unit Stimulation
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Functions of Smooth Muscles
Function of visceral smooth muscles
Visceral smooth muscle is found in the walls of all hollow organs, except the heart, and is a key player in the involuntary movements that drive the functioning of these internal organs. This tissue is arranged in...
Somatic Spinal Reflexes
One of the most well-known somatic spinal reflexes is the stretch reflex, which is activated by the sudden stretching of a muscle. This reflex involves the activation of specialized sensory receptors called muscle spindles, which are located in the muscle tissue and detect changes in the length and speed of muscle contractions. When a muscle is suddenly...
