the major ascending pathways
dorsal column-medial lemniscal, spinothalamic, and spinocerebella pathways.
which pathway carries discriminative touch and vibrations
dorsl column-medial lemniscal pathway
what pathway is the following:
1st-dorsal root ganglia
2nd-medulla
3rd-thalamus and then goes to the postsensory gyri
dorsal column-medial lemniscal
which pathway carries the sensation of pain, temperature, coarse touch and pressure
spinothalamic pathway
what pathway is the following:
1st-dorsal root ganglia
2nd-dorsal horn and crosses horn
3rd-thalamus to post central gyri
spinothalamic pathway
which pathway transmits information form the muscle or tendon to the cerebellum to coordinate skeletal muscle activity
spinocerebellar pathway
what pathway is the following:
1st-dorsal root ganglia
2nd-dorsal horn,, does not cross over, goes to cerebellum
spinocerebellar pathway
what are the major types of descending pathways
lateral corticospinal and ventral corticospinal
which pathway is the following:
1st-nerons located in the precentral gyrus (primary motor cortex) crosses over at the level of the pyramid of the medulla oblongata.
2nd-at interneuron
3rd-orginates in the ventral horn of spinal cord and goes to the muscle
descending lateral corticospinal tract
what pathway is the following:
1st-located in precentral gyri, goes to spinal cord and crosses over at the level its going to exist the spinal cord.
2nd-at interneuron
3rd-starts in ventral horn and goes to the muscle
ventral corticospinal
what are the names of the indirect pathways
tectospinal, vestibulospinal, rubrospinal, reticulospinal
