B. temperature sensation of the right leg.
C. touch sensation of the left leg.
D. touch sensation of the right leg.
3. Sensory receptors that respond to body temperature that is below normal respond to a drop in temperature by _______ frequency to send a stronger message.
A. decreased.
B. increased.
4. When proprioception is being transferred both to the primary somatosensory cortex and the cerebellum, it uses _____________ pathway and it is an example of ___________ circuit.
A. different, divergent.
B. same, divergent.
C. different, convergent.
D. same, convergent.
5. The sense of proprioception is transferred in 2 pathways:
________ pathway that results in conscious perception and
___________ pathway that results in subconscious perception.
A. proprioception only ascends on one pathway.
B. posterior column; spinocerebellar.
C. spinocerebellar; posterior column.
D. spinothalamic; spinocerebellar.
6. The gate-control theory of pain modulation states that:
A. non-painful mechanical signals can inhibit/decrease signals of pain on the 2nd order neuron.
B. non-painful mechanical signals can inhibit/decrease signals of pain on the 3rd order neuron.
C. pain sensation is modified on the level of the sensory receptors.
D. 1st order neurons can act to modify their own pain signal.
