What is the difference between lateral spinothalamic and anterior spinothalamic tracts?
Lateral spinothalamic tract = carry pain and temperature sensationsAnterior spinothalamic tract = carry crude touch and light pressure
What do ascending tracts contain?
They are sensory tracts.We have 4 tracts carrying conscious sensations = gracile + cuneate + lateral spinothalamic + anterior spinothalamicAnother 4 tracts carrying unconscious sensations = posterior spinocerebellar + anterior spinocerebellar + spino-olivary + spinotectal
What are nueral tracts that convey life saving information to the brain concerning burning pain?
The spinothalamic tract carries information about burning pain to the brain. This tract is responsible for transmitting sensory information related to temperature, pain, and crude touch from the body to the brain. If there is a burning pain sensation, signals travel along this pathway to alert the brain quickly for appropriate responses.
What is the function lateral corticospinal and anterior corticospinal?
The lateral corticospinal tract controls voluntary movements of the limbs by transmitting signals from the brain to the spinal cord. The anterior corticospinal tract also helps regulate voluntary movements but primarily controls fine movements of the limbs and trunk. Both tracts are part of the corticospinal pathway responsible for motor function.
Two terms for the massive motor tracts serving voluntary movement?
Pyramidal tracts: These are a group of motor pathways that originate in the cerebral cortex and travel through the brainstem to the spinal cord to control voluntary movement. Corticospinal tracts: These are specific pyramidal tracts that pass from the cerebral cortex to the spinal cord, playing a key role in executing voluntary motor commands.

Which spinal cord tracts carry impulses for conscious sensations?
Lateral Spinothalamic

What are the subdivisions of pyramidal tracts?
Vestibulspinal tract (majority of its fibres are uncrossed)Olivospinal tractMedial Reticulospinal tract*mnemonic to memorize: V-O-MER

What tracts of the spinal cord carry sensory information to the brain?
spinothalamic

spinothalamic
What is the function lateral corticospinal and anterior corticospinal?
The lateral corticospinal tract controls voluntary movements of the limbs by transmitting signals from the brain to the spinal cord. The anterior corticospinal tract also helps regulate voluntary movements but primarily controls fine movements of the limbs and trunk. Both tracts are part of the corticospinal pathway responsible for motor function.
Where do the lateral corticospinal tracts cross?
The lateral corticospinal tracts cross at the junction of the medulla oblongata and the spinal cord, specifically in an area known as the pyramidal decussation. This crossing allows motor signals from the brain to control the opposite side of the body, which is crucial for voluntary movement. After crossing, the fibers descend in the lateral column of the spinal cord before synapsing with motor neurons in the anterior horn.
What is the name of the synapse site in the brain for afferent fibers that travel to the sensory cortex?
i think it is the choroid plexus....not for sure though ---- Afferent sensory fibers (those returning to the brain from the periphery) synapse first in the posterior horn of the spinal cord, ascend one to two levels and decussate (cross over) at the anterior white commissure before their axons migrate to the anterior or lateral spinothalamic tracts. These then synapse again in the thalamus for integration before they go on to the post-central gyrus - the sensory cortex - and other sites in the cortex.
What is the difference between pyramidal and extrapyramidal system?
The Similarity: Pyramidal and extra-pyramidal system are the descending tracts (motor tracts) of spinal cord.The Difference:1) Their tracts -Pyramidal system = lateral and anterior corticospinal tracts + corticobulbar tractExtra-pyramidal system = rubrospinal + olivospinal + lateral and medial reticulospinal + tectospinal + vestibulospinal tracts2) "Extrapyramidal tracts" don't reach their targets by traveling through the "pyramids of medulla". Pyramidal tracts go through the pyramids of medulla.3) Pyramidal tracts may directly innervate motor neurons of spinal cord or brainstem (anterior horn cells or certain cranial nerve nuclei). But, extrapyramidal tractsindirectly control the anterior horn cells (for modulation and regulation)4) Pyramidal system is responsible for fine, isolated, precise and specific movements. Extrapyramidal system is responsible for gross, syngergic movements which require the activity of large groups of muscles
Descending tracts within the spinal cord carry what kind of impulses to the muscles?
To make it simple, they are 3 types of descending (efferent) tracts of spinal cord:Pyramidal tracts = lateral and anterior corticospinal tracts + corticobulbar tractExtra-pyramidal tracts= Vestibulospinal + Reticulospinal (Lateral and medial) + Olivospinal + Rubrospinal + Tectospinal tractsDescending autonomic
