Is anterolateral and Spinothalamic the same?

The spinothalamic tract (also known as anterolateral system or the ventrolateral system) is a sensory pathway from the skin to the thalamus. From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus.

What tract carries pain and temperature?

The Anterolateral System Lateral spinothalamic tract – carries the sensory modalities of pain and temperature.

Is the spinothalamic tract contralateral or ipsilateral?

Since the dorsal columns and spinothalamic tracts contain ipsilateral and contralateral fibres, respectively, transection of one-half of the spinal cord leads to a characteristic pattern of sensory loss. This is known as Brown–Sequard syndrome or sensory dissociation.

What is the Spinothalamic pathway?

The spinothalamic tract is a collection of neurons that carries information to the brain about pain, temperature, itch, and general or light touch sensations. The pathway starts with sensory neurons that synapse in the dorsal horn of the spinal cord.

What is the function of spinothalamic tract?

The spinothalamic tract is an ascending pathway of the spinal cord. Together with the medial lemnicus, it is one of the most important sensory pathways of the nervous system. It is responsible for the transmission of pain, temperature, and crude touch to the somatosensory region of the thalamus.

What does the spinothalamic tract detect?

Most of the fibres cross at or near the level they enter the spinal cord. The lateral spinothalamic tract carries information about pain and temperature, and the anterior spinothalamic tract carries information about crude touch. The gracile and cuneate tracts carry information about proprioception and light touch.

Is Spinothalamic contralateral?

Lesions of the spinothalamic tract If a lesion occurs in the brainstem or higher, the patient presents with loss of pain perception, crude touch and temperature sensation contralateral (other side) to the lesion.

What do Spinothalamic and Spinoreticular have in common?

Spinothalamic input is thought to effect the conscious sensation of pain, and the spinoreticular tract is thought to effect the arousal and emotional aspects of pain.
