Sensory Pathways Quiz

What is the function of the thalamus in sensory pathways?

• It transmits action potential to the CNS.

• It processes and edits incoming sensory information.

• It extends to the somatosensory cortex.

• It is entirely within the CNS.

What does the secondary neuron carry signals from?

• Sensory receptor

• Thalamus

• Posterior horn

• Somatosensory cortex

What is the role of the sensory receptor in the sensory pathway?

• To process sensory information

• To transmit action potential to the CNS

• To extend to the somatosensory cortex

• To carry signals from the posterior horn

Where does the primary neuron form a synapse in the motor pathway?

• In the primary motor cortex

• In the anterior horn of the spinal cord

• In the medulla oblongata

• In the parietal lobe

What does NMJ stand for in the context of motor pathways?

• Neural Motor Junction

• Neuromuscular Junction

• Neuron Muscle Junction

• Neuro Motor Joint

What is the role of the medulla oblongata in motor pathways?

• It is where neurons originate.

• It is where neurons cross over.

• It is where NMJs are formed.

• It is where neurons terminate.

What type of reflex involves a synapse within the spinal cord?

• Cranial

• Intrinsic

• Spinal
