You lift, bro. Answer the following about your favorite lift, the bicep curl, for 10 points each.
[10e] The bicep is this type of muscle, which is built through weightlifting. This type of muscle is one of the three types of vertebrate muscle tissue along with cardiac muscle and smooth muscle.
ANSWER: skeletal muscle
[10h] Curling involves both concentric and eccentric muscle contractions. According to this theory, muscle contraction is facilitated by myosin in the A-band pulling on actin in the I-band in a “power stroke” movement.
ANSWER: sliding filament theory [accept crossbridge cycling or the crossbridge cycle]
[10m] The actin–myosin crossbridge shortens these units to facilitate muscle contractions. These repeating units are found between two Z-lines and give cardiac and skeletal muscle their striated appearance.
ANSWER: sarcomeres
