What type of neuron sends information TO the brain?
-
Motor neuron
-
Interneuron
-
Sensory neuron
-
None of the above
Correct Answer
A. Sensory neuronExplanation
Sensory neurons are responsible for sending information from sensory receptors in the body to the brain. These neurons detect various stimuli such as touch, temperature, pain, and transmit signals to the brain, allowing us to perceive and interpret our surroundings. Motor neurons, on the other hand, transmit signals from the brain to muscles and glands, while interneurons facilitate communication between different neurons within the central nervous system. Therefore, the correct answer is sensory neuron.Rate this question:

The ________________ of the neuron receives neurotransmitters, then sends an electrical signal down the ________.
-
Axon; axon terminal
-
Dendrites; axon
-
Dendrites; soma
-
Axon; dendrites
Correct Answer
A. Dendrites; axonExplanation
Dendrites are the branch-like extensions of a neuron that receive neurotransmitters, which are chemical messengers, from other neurons. These neurotransmitters bind to receptors on the dendrites and initiate an electrical signal. This electrical signal then travels down the axon, a long fiber-like structure of the neuron, to the axon terminal where it is transmitted to the next neuron or target cell. Therefore, the correct answer is dendrites; axon.Rate this question:

A person who can move their left leg, but cannot feel anything below the left knee, probably has what type of nerve damage?
-
Sensory nerve damage
-
Motor nerve damage
-
Sensory and motor nerve damage
-
Interneuron damage
Correct Answer
A. Sensory nerve damageExplanation
A person who can move their left leg but cannot feel anything below the left knee most likely has sensory nerve damage. Sensory nerves are responsible for transmitting sensations such as touch, temperature, and pain to the brain. In this case, the person's ability to move their leg suggests that the motor nerves, which control muscle movement, are intact. However, the lack of sensation indicates a problem with the sensory nerves, resulting in the inability to feel anything below the left knee.Rate this question:
