What is the Function of upper motor neurons?
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.
Where does many upper motor neurons synapse with lower motor neurons?
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.
Why do neurone's decussate?
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.
What are neurons that carry information between sensory neurons and motor neurons?
Interneurons or association neurons.
What are the neurons that serve as links between sensory neurons and motor neurons?
interneuron
