Which of the following is classified as a pseudounipolar neuron?

• Neurons of the CNS

• Efferent neurons

• Motor neurons

• Sensory neurons

Which of the following is a key difference between the central nervous system (CNS) and the peripheral nervous system (PNS) in terms of their structure and function?

• The CNS is responsible for processing sensory input, while the PNS is responsible for motor output only

• The CNS consists of the brain and spinal cord, while the PNS includes all nerves outside the brain and spinal cord, responsible for both sensory and motor functions

• The PNS is involved in higher cognitive functions such as memory and decision-making, whereas the CNS is responsible for motor control

• The CNS has no role in regulating autonomic functions, while the PNS controls involuntary functions like heart rate and digestion

A patient was in a car accident and experienced a lesion to her anterior spinal cord at the level of L2. Which of the following impairments is most likely to follow this accident?

• Difficulty speaking

• Coordination deficits

• Weakness/paralysis of LE muscles

• Sensory loss of LE limbs
