Summary
This on-demand teaching session by Glenn Calvert, a fourth-year medical student, is an intensive and comprehensive course on neuroanatomy. The course resumes next week and includes mock OSCEs organized in collaboration with NeuroSoc and CardioSoc. The topics range from gross anatomy of the brain, covering crucial cortical and subcortical areas, to fine details about the cranial nerves and their functions. It also dives into meninges, the ventricular system, arterial supply of the brain, and spine, with an emphasis on pathologies and various spinal tracts. Join this course to deepen your knowledge and proficiency in neuroanatomy.

Description
Learning objectives
- Identify and describe the gross anatomy of the brain, including major cortical and subcortical areas such as the basal ganglia and limbic system.
- Understand and explain the function of each cranial nerve, including their sensory and motor roles, as well as the implications of dysfunction or disease in these nerves.
- Identify and describe the anatomy of the meninges, ventricles, dural venous sinuses, and arterial supply to the brain.
- Describe the anatomy of the spine and explain the roles of the DCML, spinothalamic, and spinocerebellar pathways, including potential pathologies associated with these structures.
- Understand and describe the anatomy and functions of different spinal pathways, such as corticospinal, reticulospinal, rubrospinal, tectospinal, and vestibulospinal.
