Practice questions testing deep understanding of the sliding filament theory, muscle contraction, and skeletal joints.
Q1. When a person dies, their body becomes completely stiff within a few hours, a condition known as Rigor Mortis. Using the Sliding Filament Theory of muscle contraction, explain biologically why the muscles lock into a state of permanent contraction after death.
Q2. Explain the critical role of Calcium ions (Ca++) released from the sarcoplasmic reticulum in initiating the contraction of a skeletal muscle fiber.
Q3. Assertion (A): The joint between the atlas (first vertebra) and the axis (second vertebra) in the neck is a pivot joint. Reason (R): A pivot joint allows for rotational movement, which specifically enables you to turn your head side-to-side to indicate "No."
