Neurological System Assessment Questions Questions
Question 1 of 5
If an individual has an inability to initiate speech or respond to speech with anything other than simple words is known as
Correct Answer: A
Rationale: Nonfluent aphasia, also known as Broca's aphasia, is characterized by difficulty in initiating speech or producing complex sentences. Individuals with this condition often speak in short, fragmented phrases and struggle with grammar and word order. This type of aphasia results from damage to Broca's area, a region in the frontal lobe responsible for speech production and language processing.
Question 2 of 5
Which of the following is/are type(s) of neurons?
Correct Answer: D
Rationale: Neurons can be classified into three main types: sensory neurons, motor neurons, and interneurons. Sensory neurons transmit signals from sensory receptors to the central nervous system (CNS). Motor neurons carry signals from the CNS to muscles or glands to produce a response. Interneurons, found within the CNS, integrate and process information between sensory and motor neurons. Together, these neuron types enable the nervous system to detect, process, and respond to stimuli.

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
The Central Nervous System is made up of the:
Correct Answer: A
Rationale: The central nervous system (CNS) consists of the brain and spinal cord. It is responsible for processing and integrating sensory information and coordinating motor responses. The brain is the control center for thought, emotion, and behavior, while the spinal cord serves as a conduit for signals between the brain and the peripheral nervous system. The CNS plays a central role in maintaining homeostasis and responding to external and internal stimuli.
Question 5 of 5
________ contain only afferent fibers, long dendrites of sensory neurons.
Correct Answer: B
Rationale: Sensory nerves contain only afferent fibers, which are the long dendrites of sensory neurons. These fibers transmit sensory information from the body to the central nervous system. Cranial nerves and mixed nerves contain both afferent and efferent fibers, while motor nerves contain only efferent fibers. Therefore, sensory nerves is the correct answer as they exclusively carry afferent signals.
