During the polarization phase (resting potential) of cardiac conduction, the primary extra-cellular cation (positively charged ion) is

Proteins are made up of amino acids. Which of the following statements are true regarding a reaction where amino acids are joined together to make a polypeptide? Select all that apply.

In one of the lab simulations performed during Lab 6, you found that as grip force or strength increases, the number of motor units recruited also increases.

To relax the triceps muscle, the motor neuron that controls it must be:

The ability of a cardiac muscle cell to stretch is known as its

A  change in body temperature will be detected by these sensors:  Type the best answer into the text box below:

To which specific nerve is the GREEN arrow pointing? _______

Why/how does the devil finally come to get Tom Walker?

Imagine that you are a muscle physiologist and studying muscle fatigue in human subjects.  You ask your subject to squeeze a device that measures grip strength with their dominant hand as hard as they can and for as long as they can.  You determine that your subject’s forearm muscles fatigue  at 64 seconds using the same criteria as our virtual lab simulation on this topic in Lab 6.  In a sentence or two, provide a physiological explanation for HOW (mechanistic perspective) this fatigue occurred at around that time with as much detail as you can muster.

Look at this graph carefully: A bright light with a wavelength of 600 nm will appear greenish-yellow.  Which photoreceptor(s) will be triggered or activated and represent this color of light? (YOU MAY CHOOSE MORE THAN ONE ANSWER IF IT IS APPROPRIATE)
