types of muscle skeletal which are voluntary‚ smooth muscle which are involuntary and cardiac muscle. Muscle is made up of protein filaments‚ myosin and actin. These filaments slide past each other to produce a contraction which changes both the length and shape of the cell. The primary function of the muscle is to produce both movement and force. Skeletal muscle is composed of bundles of muscle fibres containing myofibrils of thick and thin filaments (myosin and actin). Skeletal muscle have distinct

Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex‚ pose a significant health risk to the patient‚ or fail to heal properly.Bone generally has the ability to regenerate completely but requires a very small fracture space or some sort of scaffold to do so. Bone grafts may be autologous harvested from the patient’s own body‚ often from the allograft or synthetic with similar mechanical properties to bone. Most bone grafts

Skeletal Muscle Lab Introduction: Motor neurons and muscle fibers are the building blocks of motor units and where they intersect is called the neuromuscular junciton. The region where the flattened end of a motor neuron transmits neural impulses to a muscle is the motor end-plate. The end plate potentials depolarizes skeletal muscle fibers caused by neurotransmitters binding to the postsynaptic membrane in the neuromuscular junction. The process of contraction of the muscle cell is called excitation-contraction

Cortical Bone Trajectory Screws for Middle Upper Thoracic: a Anatomico-Radiological Study Introduction Pedicle screw fixation system has been widely used in spinal surgery due to its biomechanical advantage in three-dimensional fixation and short-segment fixation. However‚ Complications such as screw loosening‚ pullout and broken‚ often lead to loss of surgical construct stability‚ particularly in patients with poor bone quality [1-4]. The cortical bone trajectory (CBT)[5] technique is a theoretical
