when you get home,you smell cookies baking. you respind by walking toward the kitchen.many signals move through your nervous system in this process.which component is involved first? dendrites in your motor neuron, dendrites in your sensory neurons,axons in your motor neurons,axons in your sensory neurons
Dendrites in your sensory neurons are involved first.
In this process, the component that is involved first is the dendrites in your sensory neurons.
In this process, the first component involved is the dendrites in your sensory neurons.
The sense of smell is known as olfaction, and it involves specialized receptors in the nose that detect various molecules in the air. When you walk into your home and smell the cookies baking, the odor molecules in the air enter your nose and interact with the olfactory receptors located in the nasal cavity.
The olfactory receptors are specialized neurons with dendrites that contain receptor molecules. These dendrites receive the chemical signals from the odor molecules and generate electrical signals in response. The electrical signals are then transmitted to the axons of the sensory neurons, which are connected to the dendrites.
So, the process starts with the dendrites in your sensory neurons receiving the chemical signals from the odor molecules and converting them into electrical signals. These electrical signals will then travel through the axons of the sensory neurons to be further processed and interpreted by the brain, leading to your response of walking toward the kitchen.
