spinothalamic tract

Crude touch, pain and temperature fibers are carried in the spinothalamic tract.

Affective sensory information is transmitted via the spinothalamic tract.

Its fibres are carried in the spinothalamic tract.

Affective sensations are transmitted via the spinothalamic tract through the spinal cord.

The spinothalamic tract is a sensory pathway originating in the spinal cord.

The types of sensory information transmitted via the spinothalamic tract are described as affective sensation.

The lateral spinothalamic tract transmits pain and temperature.

These messages are then relayed to the brain along an ascending pathway, for example the spinothalamic tract.

The spinothalamic tract is damaged, resulting in loss of pain and temperature sensation to the opposite side of the body.

The neurons of the lateral spinothalamic tract originate in the spinal ganglia.

Similarly, afferent fibres from the spinothalamic tract synapse at the periaqueductal grey matter.

There are two main parts of the spinothalamic tract (STT):

Each lateral funiculus transmits the contralateral corticospinal and spinothalamic tracts.

He is brought to a hospital and subjected to a radical treatment which cuts the nerves of the spinothalamic tract so pain is no longer felt.

The spinothalamic tract is the main pathway associated with pain and temperature perception, which immediately crosses the spinal cord laterally.

These second order fibers then cross the cord via the anterior white commissure and ascend in the spinothalamic tract.

VImL also receives axons from the vestibulum and from the spinothalamic tract.

The loss of the spinothalamic tract leads to pain and temperature sensation being lost from the contralateral side beginning one or two segments below the lesion.

The location of the spinothalamic tract is important clinically due of the characteristic sensory deficits that follow certain spinal cord injuries.

Interruption of lateral spinothalamic tracts:

(The facial sensations have similar pathways, and will travel in the spinothalamic tract and the medial lemniscus also).

The substantia gelatinosa is one point (the nucleus proprius being the other) where first order neurons of the spinothalamic tract synapse.

Neurons of the cingulum receive afferent fibers from the parts of the thalamus that are associated with the spinothalamic tract.

The spinoreticular tract is an ascending pathway in the white matter of the spinal cord, positioned closely to the lateral spinothalamic tract.

After synapsing, secondary axons decussate and ascend in the anterior lateral portion of the spinal cord as the spinothalamic tract.
