This module covers the anatomy of the spinal cord and spinal nerves. The gray matter nuclei and white matter tracts of the spinal cord and their functions/connections are described. Spinal segmental nerves, nerve plexuses and their targets are discussed. Monosynaptic and polysynaptic reflexes are detailed.

This module describes the components of the motor system, including the direct and indirect motor pathways and the anatomy and circuitry of the basal nuclei and cerebellum. The differences between upper and lower motor neurons are described.

This module describes the components and functions of the autonomic nervous system and its two divisions, sympathetic and parasympathetic. It also contrasts the autonomic nervous system with the somatic nervous system. The central and peripheral neuronal components are detailed.

This module focuses on the pathways carrying sensory information from the periphery to primary sensory cortex. It includes descriptions of sensory modalities and how information concerning the internal and external information is relayed.

This module discusses and characterizes the three regions of the brainstem and the important regulatory systems found in each region. It also describes the distribution and function of the twelve cranial nerves.

This module describes the anatomy and neural pathways of the special senses. It includes the chemical senses, olfaction and taste as well as the gross anatomy of the eye and visual pathway. It also describes the auditory and vestibular apparatus including how vibration becomes sound.

This module discusses the diencephalon, cerebral cortex and limbic system. The diencephalon includes the dorsal thalamus, hypothalamus, epithalamus and subthalamus. These regions are key components of multiple systems. The cerebral cortex is highly varied and is where we think, plan and analyze. The limbic system has been dubbed our emotional brain. It is also involved in motivation and avoidance of danger.
