when u get home, you smell cookies baking. you respond by walking toward the kitchen. many signals move through your nervous system in this process. which component is involved first?
A dendrites in your sensory neurons
B axons in your motor neurons
C axons in your sensory neurons
D dendrites in your motor neurons
The correct answer is A: dendrites in your sensory neurons.
When you get home and smell cookies baking, sensory receptors in your nose detect the odor molecules in the air. These sensory receptors are connected to sensory neurons, which have dendrites that receive the signals from the sensory receptors. Therefore, the first component involved in this process is the dendrites in your sensory neurons.
