WebJan 10, 2024 · Summary. Neurons are responsible for transmitting signals throughout the body, a process that allows us to move and exist in the world around us. Different types of neurons include sensory, motor, and interneurons, as well as structurally-based neurons, which include unipolar, multipolar, bipolar, and pseudo-unipolar neurons. WebApr 6, 2024 · Motor Neurons. Motor neurons transmit electrical impulses and information from the CNS to muscles in the body. Motor neurons control all of our body movements. There are two main motor neurons subtypes: 4. Upper motor neurons: Send data from the brain to the lower motor neurons. Lower motor neurons: Send data from the upper … Upper motor neurons originate in the motor cortex located in the precentral gyrus. The cells that make up the primary motor cortex are Betz cells, which are giant pyramidal cells. The axons of these cells descend from the cortex to form the corticospinal tract. Corticomotorneurons project from the primary cortex directly onto motor neurons in the ventral horn of the spinal cord. Their axons synapse on the spinal motor neurons of multiple muscles as well as on spinal interneurons. … lincolnshire rights of way map
