Spinal Tracts

Which tracts are involved in transmitting pain and temperature sensations?

• Lateral spinothalamic tracts

• Anterior spinothalamic tracts

• Posterior spinocerebellar tracts

• Anterior spinocerebellar tracts

Which tracts are responsible for crude touch and pressure sensations, And 2nd order enter ventral posterolateral nuclei of the thalamus, synapse with 3rd order and carry information to the primary somatosensory cortex

• Lateral spinothalamic tracts

• Anterior spinothalamic tracts

• Posterior spinocerebellar tracts

• Anterior spinocerebellar tracts

Which tracts are involved in proprioception, And Neither synapse within the thalamus, so this information is not raised to the conscious level?

• Posterior spinocerebellar tracts

• Anterior spinocerebellar tracts

• Lateral corticospinal tracts

• Anterior corticospinal tracts

The Corticospinal Tracts (descending tracts)

• Corticobulbar tracts

• Lateral corticospinal tracts

• Anterior corticospinal tracts

• All of the above

Which tracts are responsible for conscious control over eye, jaw, and face muscles?

• Corticobulbar tracts

• Lateral corticospinal tracts

• Anterior corticospinal tracts

• Vestibulospinal tracts

Which tracts are responsible for conscious control over skeletal muscles?

• Lateral corticospinal tracts

• Anterior corticospinal tracts

• Medial reticulospinal tracts

• Rubrospinal tracts

Lateral corticospinal tracts

• Decussate in the pyramids of the medulla oblongata/control skeletal muscles

• Neither synapse within the thalamus, so this information is not raised to the conscious level

• Consist of four tracts involved in monitoring the subconscious motor control

• None of the above

Anterior corticospinal tracts

• Conscious control over eye, jaw, and face muscles

• Decussate at the level of the lower motor neurons/control skeletal muscle

• Conscious control over skeletal muscles

• Consist of four tracts involved in monitoring the subconscious motor control

Which tracts send information from the inner ear to monitor head position?

• Vestibulospinal tracts

• Tectospinal tracts

• Medial reticulospinal tracts

• Rubrospinal tracts

The Tectospinal Tracts

• Send information to the head, neck, and upper limbs in response to bright lights and sudden movements and loud noises

• The tectum area consists of superior and inferior colliculi

• Superior colliculi: receive visual information

• Inferior colliculi: receive auditory information

• All of the above
