A construction worker was lifting a heavy beam when he experienced a sharp pain in his back. Later on he experienced a dull throbbing ache that is not well localized. Which of the following pathways were used for the transmission of the type of pain that he perceived?

Back 2

The anterior spinothalamic pathway and the lateral spinothalamic pathway

Front 3

Neuron that is proximal to autonomic ganglion is a

Back 3

preganglionic neuron

Front 4

As you are doing an experiment to measure the resting voltage of two neurons of the same type, neuron A and B, you notice that both neurons have a resting membrane potential of -65 mv. After an Action Potential in the presynaptic neurons to those two neurons you measure the voltage in Neuron B and notice that neuron B's membrane potential is now -75mv. What is the reason for this increase in negativity of the membrane?

Back 4

Neuron B has been hyperpolarized by the neurotransmitter released from the presynaptic neuron

Front 5

A construction worker was lifting a heavy beam when he experienced a sharp pain in his back. Later on he experienced a dull throbbing ache that is not well localized. Which of the following pathways were used for the transmission of the type of pain that he perceived?

Back 5

The spinothalmic pathways and the spinolimbic pathway

Front 6

Front 7

In a typical multipolar neuron which part of the neuron provides the greatest surface area for synaptic reception?

Back 7

Dendritic process

Front 8

A 21 year old soldier had a spinal cord injury in combat that resulted in a hemisection of the spinal cord, on the right side, at spinal level T10. Which of the following sensory deficit would be picked up on examination below the level of the lesion?

One of your patients had a stroke one week ago. The focus of your treatment is to have him lift his partially paralyzed arm to place it on the table. Your strategy is to rely on repetitive movements of the same type to master the task. Which of the following aspects of neuroplasticity would be the basis of your treatment strategy?

Back 14

Long-term potentiation
