Question

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?

Answer 1

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.
