Balance and coordination
Crude touch and pressure
Which structure in the spinal cord contains sensory fibers for fine touch from the lower limbs?
Fasciculus cuneatus
Fasciculus gracilis
Lateral corticospinal tract
Spinothalamic tract
Dorsal root ganglia
Among the following, which is the location of the dorsal column medial lemniscus tract?
A
B
C
D
Which statement is related to the second order neuron in the dorsal column?
A type of unipolar neuron.
Decussates in the spinal cord.
Receives impulses from the receptor.
Transmits impulses to the cerebral cortex.
What is the pathway for conscious proprioception impulses from the upper trunk?
A
B
C
D
When the foot is touched, the sensation of touch travels to the brain through which structure?
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
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
The first-order neurons of the spinothalamic tract have their cell bodies located in the:
Anterior horn of spinal cord
Posterior horn of spinal cord
Dorsal root ganglion
Thalamus
A patient has loss of pain and temperature sensation on the right side of the body, while vibration is preserved.Which of the following best explains this pattern of sensory loss?
Damage to the right spinothalamic tract before decussation
Damage to the left dorsal column after decussation
Damage to the right dorsal column before decussation
Damage to the left spinothalamic tract after decussation
Which sequence correctly represents the order of neurones in the spinothalamic pathway?
Dorsal root ganglion → thalamus → cerebral cortex
Posterior horn → dorsal root ganglion → thalamus
Dorsal root ganglion → posterior horn → thalamus → sensory cortex
Posterior horn → anterior horn → thalamus → cortex
