How Do You Spell DECUSSATIO LEMNISCORUM?

1. Decussatio lemniscorum refers to a neurological term used to describe the decussation or crossing-over of the lemniscus fibers in the brainstem. The decussatio lemniscorum specifically occurs in the medulla oblongata, the lowermost part of the brainstem.

   The lemniscus is a band of nerve fibers that transmits sensory information, particularly regarding touch, vibration, and proprioception (sense of body position), from the body to the brain. The sensory information is collected by receptors in the body and then travels through specific nerve pathways to the brain, ultimately reaching the primary somatosensory cortex.

   During the decussatio lemniscorum, the lemniscus fibers cross from one side of the body to the other side of the brainstem. This crossing-over allows sensory information from the left side of the body to be processed by the right side of the brain, and vice versa. The decussation ensures that sensory information is properly relayed and interpreted in the brain, resulting in a coherent perception of the body's sensations.

   The decussatio lemniscorum is a crucial step in the transmission of sensory information through the central nervous system. It is an essential aspect of the overall organization and functionality of the somatosensory pathways within the brain, contributing to the brain's ability to perceive and interpret touch, proprioception, and other related sensory input from the body.

2. Decussation of the lemniscus or fillet, sensory decussation of the medulla oblongata, an intercrossing of fibers in the median plane of the medulla or the dorsal aspect of the pyramids, immediately above the level of the decussation of the pyramids.
