What is a dendrite? (1 point)
Responses
It is a cell that sends signals to the body to move.
It is a cell that sends signals to the central nervous system based on sensory input.
.
It is the part of the neuron that carries information away from the cell body.
It is the part of a neuron that carries information to the cell body.
The correct answer is: 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? (1 point)
Responses
nerves
messages
stimuli
signals
3. How do signals from sensory neurons reach motor neurons? (1 point)
Responses
Motor neurons signal for the body to move the signal toward them
Signals move from dendrite to dendrite towards motor neurons
Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons
Signals from sensory neurons do not get sent to motor neurons
2. The correct answer is: stimuli.
3. The correct answer is: Through interneurons in the brain and spinal cord that connect sensory neurons and motor neurons.

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? (1 point)
Responses
axons in sensory neurons
axons in motor neurons
dendrites in motor neurons
dendrites in sensory neurons
4. The correct answer is: central nervous system.

- It is the part of a neuron that carries information to the cell body. (1 point)
The correct answer is: It is the part of a neuron that carries information to the cell body.
A dendrite is a specialized structure found on the neuron cell body that receives and carries incoming signals from other neurons or sensory receptors. To arrive at this answer, you can use various sources such as textbooks, academic articles, or reliable websites that provide information on neuroscience or the structure and function of neurons. These sources will provide detailed explanations and diagrams illustrating the different parts of a neuron, including the role of dendrites in receiving signals.
