They come in two main subtypes, namely the upper motor neurons and the lower motor neurons. The upper motor neurons originate in the brain and travel downward to connect with the lower motor neurons. The latter localize both in the brainstem and the spinal cord and are the mediators These neurons have large nuclei and well defined cell bodies. In a SPINAL CORD cross section, examine the large, irregularly shaped motor neuron cell bodies found in each anterior horn. The round nucleus in these cells is lighter-staining than the cytoplasm ; identify also the nucleolus , a spherical dark-staining body within the nucleus. Motor pathways involve two neurons, referred to as the upper and lower motor neurons. The pyramidal cells of the motor cortex, as well as the neurons in subcortical motor nuclei that give rise to other descending motor pathways, are called upper motor neurons.

Motor neurons anatomy

The function of lower motor neurons can be divided into two different groups: the lateral corticospinal tract and the anterior corticalspinal tract. The lateral tract contains upper motor neuronal axons that synapse on the dorsal lateral lower motor neurons, which are involved in distal limb control. Motor neurons (MNs) are neuronal cells located in the central nervous system (CNS) controlling a variety of downstream targets. There are two main types of MNs, (i) upper MNs that originate from the cerebral cortex and (ii) lower MNs that are located in the brainstem and spinal cord.
