'Yank': A new term in biophysics

Biologists and biomedical engineers are proposing to define the term "yank" for changes in force over time, something that our muscles and nerves can feel and respond to.

How do muscle and tendon connections last a lifetime?

Muscles are connected to tendons to power animal movements such as running, swimming or flying. Forces are produced by contractile chains of the proteins actin and myosin, which pull on muscle-tendon connections called attachments. ...
