Is the statement below True or False? The myosin in smooth muscle requires phosphorylation before it can bind to ATP.

The portion of the nervous system that conducts impulses from the skin, joints, skeletal muscles, and special senses is the ___________ division.  

Is the statement below True or False? The pia mater lies directly deep to the dura mater.

Neuron Action Potential – Part 2 Take a look again at the graph of an action potential on the membrane of a neuron (given below). Describe what is happening in the voltage-gated sodium channels and the voltage-gated potassium channels during the point in time on your graph 1) when threshold is reached, 2) during the depolarization phase, 3) during the repolarization phase, and 4) during the hyperpolarization phase. What are the two ion channels doing at each of these 4 points/phases? Tip: remember that sodium channels have two gates and three states, whereas potassium channels have one gate and two states.  

In neurophysiology, the term “temporal summation” refers to the additive effect of…

A familiar type of monosynaptic reflex that uses muscle spindle mechanoreceptors to monitor the length of skeletal muscle fibers and causes muscle contraction in response is called the…

In the micturition reflex, high volumes of urine stretch the wall of the bladder. This excites interneurons in the sacral region of the spinal cord. These interneurons cause pelvic splanchnic motor neurons to fire. The bladder contracts and pushes urine against the opening to the urethra. Check the boxes that identify the type(s) of reflex represented by the micturition  reflex. Check all that apply (i.e., there could be more than one right answer).

Match the symptoms to the nervous system structure that is damaged. Choose the ONE BEST ANSWER for each set of symptoms. Note: Not all structures will be used as answers.

Which of the following statements regarding myosin in skeletal muscle is TRUE?  

The increase in muscle tension that occurs with an increase in the intensity (voltage) of a stimulus is called…
