Your friend runs out of gas and you have to help push his car. discuss the sequence of bones and joints that convey the forces passing from your hand through your upper limbe and your pectirak girdle and to your axial skeleton?

Respuesta :

Answer: Metacarpal bones of your hand-Carpal bones at the base of your hand-Midcarpal and radiocarpal joints-Radius and ulna bones of the forearm- Elbow joint-Humerus of the arm-Glenohumeral joint-Scapula-Acromioclavicular joint-clavicle-Sternoclavicular joint- Sternum

Explanation: The process is as follows:

Pushing against the car,lt will cause forces to pass from the metacarpal bones of your hand into the carpal bones at the base of your hand. Again, Forces will also pass through the midcarpal and radiocarpal joints into the radius and ulna bones of the forearm, Which will pass the force through the elbow joint into the humerus of the arm, and then through the glenohumeral joint into the scapula. The force from the scapula will then move through the acromioclavicular joint into the clavicle, and then pass through the sternoclavicular joint into the sternum,a part of the axial skeleton.

The force will start in the metacarpal bones and pass through the midcarpal and radiocarpal joints, reaching the bones of the radius and ulna, passing through the elbow joint. Then, the force will be guided to the humeral bones, reaching the glenohumeral joint, reaching the scapula, the acromioclavicular joint, the clavicle, the sternoclavicular joint, and ending in the sternum bone.

We can arrive at this answer because:

  • When pushing a car, all bones and joints in the shoulders, arms, and hands will be used.
  • This movement will be done with the stimulation of a force that will follow a well-defined path to be able to move the car.
  • This path will be done as shown above and the order of the places where the force hits is important for the movement to be performed efficiently.

It is important to emphasize that during the execution of the movement, a specific amount of force must be used so as not to cause defects in any bone or joint.
