What else can I help you with?
What occurs when the trachealis muscle contracts and in what activities might this action be very helpful?
When the trachealis muscle contracts, it reduces the diameter of the trachea, helping to regulate airflow and adjust resistance in the respiratory system. This action can be particularly helpful during activities that require increased respiratory effort, such as exercise or periods of high air demand like during coughing or sneezing.
What happens to the length of a muscle when it contracts?
When a muscle contracts, it shortens in length.
What is the function of the trachealis muscle?
The primary function of the trachealis muscle is to constrict the trachea, allowing air to be expelled with more force e.g. during coughing.

What is located on the posterior side of the trachea and allows the esophagus to expand anteriorly during swallowing?

What happens when an entire muscle contracts strongly and stays contracted?
when a muscle cramps
If one muscle contracts what happens to the other one?

What happens to the muscle fibers in your biceps when you bend your arm?
it contracts
When the muscle contracts what happens to the tendon and bone?
When the muscle contracts, the tendon pulls on the bone to create movement. The tendon is the connective tissue that attaches the muscle to the bone, so when the muscle contracts, it exerts force on the tendon, which in turn moves the bone.
