decussation of pyramids
Upper motor neurons are responsible for initiating voluntary movements by sending signals from the brain to the lower motor neurons in the spinal cord. They play a crucial role in coordinating and executing motor functions throughout the body. Dysfunction of upper motor neurons can result in symptoms such as muscle weakness, spasticity, and impaired coordination.
Neurons decussate, or cross over, at different points in the nervous system to allow for communication between the two hemispheres of the brain. This crossing helps with functions like coordination, sensory processing, and motor control in the body.
Many upper motor neurons synapse with lower motor neurons in the ventral horn of the spinal cord. This is where the cell bodies of lower motor neurons are located, allowing for the direct control of muscle function.
Interneurons or association neurons.

No! Only neurons of the specific (lemniscal) & non-specific (anterolateral) pathways decussate and sensation is therfore interpreted in the opposite cerebral hemisphere.Spinocerebellar ascending pathways transmit proprioceptive sensory stimuli to the same side of the cerebellum.

Motor neurons and intern neurons
Sensory neurons and motor neurons are connected by interneurons in the central nervous system. Interneurons help relay signals from sensory neurons to motor neurons, allowing for the coordination of sensory input and motor output in response to various stimuli.
Sensory Neurons
Efferent motor neurons stimulate muscle contractions.
