A
B
C
D
Which tract is responsible for transmitting pain and temperature sensations?
Spinocerebellar tract
Lateral spinothalamic tract
Medial lemniscus tract
Corticospinal tract
which tract carries proprioceptive sensory information from the upper limbs to the brain?
fasciculus gracilis (medial part of dorsal column)
spinothalamic tract
fasciculus cuneatus (lateral part of dorsal column)
anterior corticospinal tract
Which part of the brain processes fine touch and proprioception?
Thalamus
Cerebellum
Medulla oblongata
Primary somatosensory cortex
What is the primary function of the fasciculus cuneatus?
Transmit pain and temperature from the lower body
Transmit fine touch and proprioception from the upper body
Transmit balance information to the cerebellum
Transmit motor signals to the limbs
Where do the fibers of the DCML pathway decussate?
In the spinal cord
In the medulla oblongata
In the midbrain
In the thalamus
Which of the following is a clinical sign of spinothalamic tract damage?
Loss of proprioception and vibration sense
Loss of pain and temperature sensation
C. Muscle weakness and spasticity
Inability to perform fine motor tasks
Where does the spinothalamic tract decussate (cross over) in the nervous system?
At the level of the Thalamus
At the level of the Medulla
Which of the following correctly describes the parts of the spinothalamic tract and their functions?
The lateral spinothalamic tract carries fine touch, while the anterior spinothalamic tract carries proprioception.
The anterior spinothalamic tract carries proprioception, and the lateral spinothalamic tract carries crude touch.
The lateral spinothalamic tract carries pain and temperature, while the anterior spinothalamic tract carries crude touch and pressure.
Both anterior and lateral spinothalamic tracts carry pain and temperature
At which nervous system level does the spinothalamic tract decussate (cross over)?
At the level of the Thalamus
In the medulla
At the level of the spinal cord near the point of entry
