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.
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.
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.
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

Do Second-order neurons of ascending sensory pathways always decussate.?
No, second-order neurons of ascending sensory pathways do not always decussate. Some pathways decussate at the level of the medulla or spinal cord, while others do not cross over until reaching the thalamus. It depends on the specific sensory pathway and the type of information being transmitted.
What neurons carry motor impulses?
Motor neurons

Sensory neurons and motor neurons are connected by?
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.
What type of neurons are multipolar?
Motor neurons and intern neurons
Are neurons that relay impulses from sensory neurons to motor neurons?
Sensory Neurons
What is A neuron that can cause muscles to contract?
Efferent motor neurons stimulate muscle contractions.
What are neurons that relay impulses from sensory to motor neurons?
Sensory Neurons
What are neurons that carry information between sensory neurons and motor neurons?
Interneurons or association neurons.
What neurons that move impulses from the brain?
MOTOR neurons
