|
Neurons that relay information within the CNS and are the location of information processing are called |
interneurons |
|
|
From medial to lateral, what are the muscles of the hamstring group? |
semimembranosus, semitendinosus, biceps femoris |
|
|
The main immediate source of ATP (lasting about 10 seconds) as muscle contractions begin comes from: |
creatine phosphate. |
|
|
If oxygen is not available, the muscle fiber will produce ATP by |
anaerobic catabolism |
|
|
Through which ATP-generating mechanism can long-lasting muscle contractions be sustained? |
oxidative catabolism |
|
|
Wave summation, in which the muscle can only partially relax between contractions, will lead to |
unfused tetanus |
|
|
The type of contraction represented by a single stimulus/contraction/relaxation sequence is a(n) |
twitch |
|
|
Compared to Type I fibers, Type II fibers |
can generate faster, more powerful contractions |
|
|
During the absolute refractory period, production of another action potential is not possible. |
True |
|
|
Axons with a smaller diameter can conduct nerve impulses more quickly than axons with a larger diameter. |
False |
|
|
The majority of synapses in the nervous system are: |
chemical |
|
|
Which of the following must happen first in the order events at a chemical synapse? |
Calcium ion channels in the axon terminal open. |
|
|
Which of the following is most likely to produce an action potential? |
excitatory postsynaptic potential (EPSP) |
|
|
When a second EPSP arrives at a single synapse before the effects of the first have disappeared, what results? |
temporal summation |
