Which of the following is NOT an action of brachioradialis?

A. Elbow flexion
B. Elbow extension
C. Supination
D. Pronation

Expert Solution

The brachioradialis muscle in our human body specifically originates on our bodies lateral supracondylar ridge of our bodies humerus bone . This specific rough margin of our body is located specifically on the lower end of our humerus bone . From that point the brachioradialis muscle specifically travels the length of our human forearm. It specifically inserts into our bodies distal radius, at the radial styloid process which is a bony projection

This brachioradialis muscle that is located in our human forearm helps in the flexion processs of the elbow joint .so option a is wrong

The brachioradialis muscle in our body will also assists with pronation of our forearm so option d is wrong

The brachioradialis muscle in our body also assist with supination of the forearm.so option c is wrong

Option b is the answer as the brachioradialis muscle will not assist in the elbow extention . The primary extention muscle of our body is the triceps brachi muscle . So it is wrong answer

Which of the following statements about action potentials is true? Action potentials trigger a reversal of...

Which of the following statements about action potentials is true? Action potentials trigger a reversal of the membrane polarity, with the interior of the cell becoming positively charged. Action potentials trigger reversal of the membrane polarity, with the interior of the cell becoming negatively charged. Action potentials trigger depolarization of the membrane by opening potassium voltage-gated channels. Action potentials lead to a sudden impermeability of the membrane to the transport of ions. Action potentials lead to a sudden rush of...
