Nettet8. aug. 2024 · Introduction to LMNs. The cell body of a LMN lies within the ventral horn of the spinal cord or the brainstem motor nuclei of the cranial nerves which have motor modalities. Therefore, the cell body of a LMN lies within the central nervous system (CNS). The axon of a LMN exits the CNS and forms the somatic motor part of the … NettetThe central nervous system includes the spinal cord and the brain. The brain is divided into 3 main sections—the brain stem, which controls many basic life functions, the cerebrum, which is the center of conscious decision-making, and the cerebellum, which is involved in movement and motor control.The spinal cord of dogs is divided into regions …
