Question

25 true or false 0.7 points the secondary or second order neuron is the neuron that decussates in the somatosensory pathway. true false 26 multiple choice 0.7 points in gustation the type i cells detect sour spicy is a submodality of taste taste information is carried to the parietal lobe the receptor cells are capable only of producing a graded potential 27 multiple choice 0.7 points hydrogen ions activate which taste sensation? umami sweet salty sour bitter

Explanation:

• For question 25: In the somatosensory pathway, the secondary (second - order) neuron is the one that decussates (crosses over to the opposite side of the body).
• For question 26: Taste receptor cells can only produce a graded potential. Type I cells detect salty, spicy is not a sub - modality of taste (it's a pain response), and taste information is carried to the gustatory cortex, not the parietal lobe.
• For question 27: Hydrogen ions ($H^+$) are associated with the sour taste sensation.

Answer:

1. True
2. The receptor cells are capable only of producing a graded potential
3. Sour
