Sensory and Motor Features of Lateral and Anterior Sections
Sensory Perform of Lateral and Anterior Sections
The lateral corticospinal tract, positioned within the lateral portion of the spinal twine, is chargeable for controlling voluntary actions of the limbs. It transmits indicators from the cerebral cortex to the motor neurons within the spinal twine, which then activate the muscle mass of the limbs.
The anterior corticospinal tract, positioned within the anterior portion of the spinal twine, is chargeable for controlling voluntary actions of the trunk and neck. It transmits indicators from the cerebral cortex to the motor neurons within the spinal twine, which then activate the muscle mass of the trunk and neck.
Motor Perform of Lateral and Anterior Sections
The lateral portion of the spinal twine is chargeable for controlling voluntary actions of the limbs. This contains actions resembling reaching, greedy, and strolling. The lateral corticospinal tract, which originates within the motor cortex of the mind, transmits indicators to the motor neurons within the spinal twine, which then activate the muscle mass of the limbs.
The anterior portion of the spinal twine is chargeable for controlling voluntary actions of the trunk and neck. This contains actions resembling bending, twisting, and turning. The anterior corticospinal tract, which originates within the motor cortex of the mind, transmits indicators to the motor neurons within the spinal twine, which then activate the muscle mass of the trunk and neck.
| Tract | Perform |
|---|---|
| Lateral corticospinal tract | Voluntary actions of the limbs |
| Anterior corticospinal tract | Voluntary actions of the trunk and neck |
Medical Findings of the Brown-Sequard Syndrome
The medical findings of the Brown-Sequard syndrome are characterised by a unilateral lack of motor, sensory, and autonomic capabilities on the aspect of the harm, and preservation of motor, sensory, and autonomic capabilities on the alternative aspect. The precise medical image relies on the extent of the spinal twine lesion and the extent of harm to the assorted tracts.
The next desk summarizes the medical findings within the Brown-Sequard syndrome:
| Facet of Harm | Motor Perform | Sensory Perform | Autonomic Perform |
|---|---|---|---|
| Ipsilateral | Loss | Lack of proprioception, vibration, and two-point discrimination | Loss |
| Contralateral | Preserved | Lack of ache and temperature sensation | Preserved |
It is very important notice that the Brown-Sequard syndrome is a uncommon situation, accounting for lower than 1% of all spinal twine accidents. It’s extra frequent in youthful sufferers and in these with penetrating trauma. The prognosis for the Brown-Sequard syndrome relies on the extent and severity of the harm.
Contralateral Lack of Ache and Temperature Sensation (Lateral Part)
The lateral part of the spinal twine accommodates the spinothalamic tracts, which carry indicators for ache and temperature sensation. Injury to the lateral part of the spinal twine leads to contralateral lack of ache and temperature sensation. Which means the affected person will lose the power to really feel ache or temperature on the alternative aspect of the physique from the injury.
The next desk summarizes the consequences of harm to the lateral part of the spinal twine:
| Facet of Twine Injury | Facet of Sensory Loss |
|---|---|
| Left | Proper |
| Proper | Left |
Contralateral lack of ache and temperature sensation is a critical neurological deficit that may considerably influence a affected person’s high quality of life. It could possibly make it troublesome to carry out on a regular basis duties, resembling cooking, consuming, and bathing. It could possibly additionally result in accidents, because the affected person might not be capable to really feel ache or discomfort. There isn’t any remedy for contralateral lack of ache and temperature sensation, however there are therapies that may assist to enhance the affected person’s high quality of life.
Preservation of Proprioception and Contact (Posterior Part)
Brown Sequard Syndrome (BSS) is characterised by the lack of particular neurological capabilities on one aspect of the physique, relying on the extent of spinal twine injury.
Posterior Part
The posterior part of the spinal twine accommodates ascending tracts that carry sensory data to the mind, together with proprioception (place sense) and contact.
Unilateral Lack of Proprioception and Contact
A lesion within the posterior part of the spinal twine leads to the lack of proprioception and contact on the ipsilateral (similar) aspect of the physique under the extent of the lesion.
Unaffected Contralateral Facet
In distinction, proprioception and contact are preserved on the contralateral (reverse) aspect of the physique as a result of the sensory data from that aspect crosses to the opposite aspect of the spinal twine earlier than ascending to the mind.
Desk: Sensory Involvement in Brown Sequard Syndrome
| Facet of Lesion | Ipsilateral | Contralateral |
|---|---|---|
| Proprioception | Loss | Preserved |
| Contact | Loss | Preserved |
Remedy Choices for Brown-Sequard Syndrome
There isn’t any particular remedy for Brown-Sequard syndrome, however therapy might help handle signs and enhance high quality of life. Remedy choices range relying on the severity of the signs and should embrace:
Remedy

- Electrical stimulation of the spinal twine
- Transcranial magnetic stimulation (TMS)
- Glial cell transplantation
| Remedy | Description |
|---|---|
| Electrical stimulation of the spinal twine | Implants ship electrical impulses to the spinal twine to enhance operate. |
| TMS | Magnetic pulses stimulate particular areas of the mind to enhance operate. |
| Glial cell transplantation | Surgeons implant glial cells from a donor into the injured space of the spinal twine to advertise restore. |
