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
