A man wakes from sleep, hears a strange noise, becomes alarmed and runs downstairs. Which of the following describes the corresponding events taking place in his nervous system ?

1)sensory neuron>spinal neuro>brain>motor neuron
2)sensory neuron>brain>spinal cord>motor neurons
3)motor neurons>brain>spinal cord>sensory neurons
4)motor neurons>spinal cord>brain>sensory neurons

I think #1. Can you check?
THANK YOU

Agree

Its wrong....

Yes, you are correct. The correct sequence of events in the nervous system in this scenario would be:

1) Sensory neuron: The man's sensory neurons detect the strange noise as it reaches his ear.
2) Spinal neuron: The sensory information is then passed on to the spinal cord, where it is processed.
3) Brain: The processed information is sent to the brain, which interprets the sound as something strange and potentially alarming.
4) Motor neuron: The brain then initiates a response, sending signals through motor neurons.

Therefore, the correct sequence is: sensory neuron > spinal neuron > brain > motor neuron. This corresponds to option 1.

To determine the correct answer, let's break down the sequence of events in the man's nervous system.

1) The man wakes from sleep and hears a strange noise. This sensory input (auditory stimulus) is picked up by sensory neurons in his ears.

2) The sensory neurons transmit the information to the spinal cord, which is responsible for relaying signals to and from the brain.

3) From the spinal cord, the information is sent to the brain, where it is processed and interpreted to understand the nature of the strange noise. This involves various regions of the brain working together.

4) Once the brain has processed the information and determined that the man should be alarmed, it sends a signal to motor neurons.

5) The motor neurons, which are connected to muscles, receive the signal from the brain and initiate the man's response, which is running downstairs.

Based on this breakdown, we can see that the correct answer is option 2) sensory neuron > brain > spinal cord > motor neurons. This sequence accurately describes the flow of information and the specific order in which events occur in the man's nervous system.
