Tendon excursion is the distance that a tendon can move when a muscle contracts and relaxes. It is the length change that occurs in the tendon as the muscle produces movement at a joint. Tendon excursion is important for proper muscle function and joint mobility.
When a muscle contracts, it shortens and tightens, causing movement. This process occurs in the human body when signals from the brain travel through nerves to the muscle, triggering the release of calcium ions. These ions bind to proteins in the muscle cells, causing them to slide past each other and contract. This contraction allows the muscle to generate force and move the body.
Dorsiflexion is the movement that brings the foot closer to the shin. This movement typically occurs at the ankle joint.
Adduction movement occurs when a muscle moves a limb towards the midline of the body. This movement decreases the angle between the limb and the body.
Diffusion.
When the gluteus maximus contracts concentrically, hip extension occurs. This means the thigh moves backward, bringing the leg into alignment with the body.
Flexion
When the rectus abdominis contracts concentrically, it primarily results in the flexion of the trunk. This movement brings the rib cage closer to the pelvis, effectively bending the torso forward. It is commonly engaged during activities such as sit-ups or crunches. Additionally, this contraction helps stabilize the pelvis and lower back during various movements.
The bicep muscle relaxes. It is vice-versa when the bicep muscle contracts.
The extension in the elbow occurs when the triceps muscle contracts, causing the forearm to straighten out. This movement is essential when performing actions like pushing and lifting objects.
When a movement occurs in two planes, it is called turbulence.
dilation
Movement within the cell occurs by microtubules, which act like railroads to help transportation of vessicles and organelles. Movement of the cell itself occurs by either the cilia or the flagella.
A supernova occurs.
A supernova occurs.
The a voluntary muscle contracts involuntarily, you will see a little movement through your skin. These movements are often called Tics, Twitches, and Spasms. If the involuntary contractions are widespread and very energetic, they may be called, "Seizures".
