How do signals move from a sensory neuron toward the brain? (1 point)
A.) Interneurons help signals move from one neuron to another toward the spinal cord.
B.) Motor neurons signal for the body to move the signal toward the brain.
C.) The signal is sent through the part of the neuron that is in contact with the spinal cord.
D.) Signals move from dendrite to dendrite towards the brain.
PLEASE I NEED ANSWER ASAP!!!
Hello!
Whoever wants the full answer to the Quick Check -
1: What is a dendrite?
Answer: It is the part of a neuron that carries information to the cell body.
2: What is the term for changes in the internal or external environment that cause a response?
Answer: Stimuli
3: How do signals from sensory neurons reach motor neurons?
Answer: Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons
4: What part of the nervous system is completely protected by bone?
Answer: Central nervous system
5: You see a mosquito land on your hand and swat at it. A signal passes through many parts of different neurons to make this happen. Which component of the nervous system is the last to be involved in this process?
Answer: axons in motor neurons
The answer is D.
@vouqu the answer is not D, its, Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons
also the order might switch, but it will still be Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons
I NEED FULL ANSWERS HALPPPP
Thank you for providing the full answers! Let me know if you need any further assistance.
The correct answer is C.) The signal is sent through the part of the neuron that is in contact with the spinal cord.
To understand how signals move from a sensory neuron toward the brain, we need to understand the basic structure of a neuron. Neurons consist of three main parts: the dendrites, the cell body (or soma), and the axon.
When a sensory stimulus is detected, it triggers an electrical signal called an action potential in the sensory neuron's dendrites. These electrical signals are produced by changes in the balance of ions inside and outside the neuron.
The action potential then travels down the neuron's axon, which is a long, slender extension of the neuron. The axon is covered in a protective layer called the myelin sheath, which speeds up the conduction of the electrical signal.
At the end of the axon, there are tiny branches called axon terminals. These terminals form synapses, which are junctions with other neurons.
In the case of a sensory neuron, the signal is typically transmitted to an interneuron, which is a type of neuron that connects other neurons. The interneuron helps the signal move from one neuron to another, especially toward the spinal cord.
Once the signal reaches the spinal cord, it is further transmitted to other parts of the central nervous system, including the brain. This transmission occurs through a complex network of interconnected neurons.
Therefore, the correct answer is C.) The signal is sent through the part of the neuron that is in contact with the spinal cord.
