Where do the first order neurons carrying afferent information synapse with second order neurons?
Dorsal root ganglia
Which part of the spinal cord contains ascending fibers from C1-T6 for tactile and proprioceptive information?
Fasciculus cuneatus
Where do the axons of the second-order neurons sweep around after synapsing in the medulla?
Central grey matter
What is the name of the compact bundle through which the fibers ascend after decussating?
Medial Lemniscus
Where do the fibers of the DORSAL COLUMN MEDIAL LEMNISCUS TRACT terminate by synapsing on the third-order neurons?
Ventral posterolateral nucleus of the thalamus
Study Notes
Dorsal Column Medial Lemniscus Tract
- Conveys tactile and proprioceptive sensory information
Synapse of First and Second-Order Neurons
- First-order neurons carrying afferent information synapse with second-order neurons in the medulla
Spinal Cord Components
- The cervical and thoracic regions of the spinal cord (C1-T6) contain ascending fibers for tactile and proprioceptive information
Axons of Second-Order Neurons
- Axons of second-order neurons sweep around the central canal in the medulla after synapsing
Compact Bundle
- The compact bundle is called the medial lemniscus, through which fibers ascend after decussating
Termination of Dorsal Column Medial Lemniscus Tract
- Fibers of the Dorsal Column Medial Lemniscus Tract terminate by synapsing on third-order neurons in the thalamus
Test your knowledge about the conveying of sensory information related to touch, proprioception, vibration, and discrimination through the Dorsal Column Medial Lemniscus Tract. Explore the pathways and synapses involved in this sensory transmission process.
