(23 cards)
Describe the process of neurulation
What are neural crest cells and what do they develop into?
Describe the development of the alar plate and the basal plate
Describe the function of the extra ocular muscles as assessed clinically in the H-test and name the cranial nerves innervating these muscles
Describe the wiring of horizontal gaze for both saccades and pursuit movements
Differentiate between vertical and horizontal gaze and where they are located in the brainstem
Explain convergence and divergence movements and the role of this assessment in the differential diagnosis of gaze disorders
Describe the principles of the pupillary light reflex and accommodation
Relate the surface markings including cranial nerve roots of the brainstem and how they relate to the tracts and structures within the brainstem
Compare the corticobulbar tract with the corticospinal tract
Define the modalities carried by CN V and its respective nuclei in the brainstem
Define the modalities carried by CN VII and its respective nuclei in the brainstem
Discuss what a lesion to CN VII would result in
Describe the key anatomical characteristics and functions of the spinal cord
Describe the main descending motor tract: corticospinal tract
Differentiate between upper motor neuron and lower motor neuron lesions
Describe the visceral motor innervation of the bladder
Differentiate the main sensory tracts in the brainstem: the posterior column medial lemniscus pathway and the anterolateral system
Apply the neuroanatomy of the spinal cord to a clinical approach to spinal cord lesions
Describe the expansion of the CNS in the development of the nervous system
Relate the development of segmented somites to the organization of the nervous system, in particular the spinal cord
