When you 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. Axons in your motor neurons
B. Dendrites in your motor neurons
C. Dendrites in your sensory neurons
D. Axons in your sensory neurons
C. Dendrites in your sensory neurons
The component involved first in this process is:
C. Dendrites in your sensory neurons
The correct answer is C. Dendrites in your sensory neurons.
When you smell the cookies baking, the scent molecules stimulate the receptors in your nose, which are connected to sensory neurons. These sensory neurons have dendrites that receive the signals from the receptors and transmit them to the cell body.
So, the first component involved in this process is the dendrites in your sensory neurons. They receive the sensory input from the environment and convert it into electrical signals, which then travel through the rest of the neuron, including the cell body, axon, and axon terminals.
After the sensory input is received and processed by the sensory neurons, it is transmitted as an electrical impulse along the axons of those neurons and sent to the brain. Once the signal reaches the brain, it activates the appropriate regions associated with the perception of smell, and you respond by walking toward the kitchen to investigate the baking cookies.
