Understanding Muscle Contraction and Response

The video tutorial demonstrates an experiment where Hannah is connected to an electrode to sense hand contractions. These signals are processed by a Spiker box and sent to a T machine, which applies a shock to Noah, causing his muscles to contract. The experiment aims to show the transfer of muscle signals and the resulting physical response. During the demonstration, unexpected leg movement is observed, leading to a discussion about the sensations experienced and the experiment's outcomes.

What is the role of the Spiker box in the experiment?

• To sense contractions directly

• To apply a shock to Noah

• To transmit signals to the T machine

• To measure the strength of contractions

What should happen when Hannah contracts her hand?

• Noah's hand should contract

• Noah's leg should move

• Hannah's hand should relax

• Noah should feel a shock

What is Noah instructed to do during the experiment?

• Turn his hand over

• Relax his muscles

• Move his leg

• Contract his hand

What unexpected reaction occurs during the experiment?

• Hannah's hand stops contracting

• Noah's leg moves

• The Spiker box malfunctions

• The electrode stops working

What does Hannah describe the sensation of contracting as?

• A tingling feeling

• A sharp pain

• A gentle push

• A leg movement
