Where can the cerebellar tonsils herniate through, why do they herniate and what is it called.

What are the classic histological features of Meningioma
Rounded masses with well­defined dural bases that compress underlying brain tissue. The surface is usually encapsulated with thin, fibrous tissue and may have a polypoid appearance. Whorled pattern of cell growth is also seen, as well as calcified psammoma bodies. Presence of syncytial, fibroblastic, and transitional cells is also possible.

explain the pupillary light reflex
1. Upon reception of bright light, photoreceptors of the retina are activated, which relay the information to optic nerve. 2. Optic nerve carries afferent fibers to the midbrain on BOTH sides and synapses on efferent fibers 3. Pre­ganglionic parasympathetic fibers travel with the oculomotor nerve and synapse on ciliary ganglia 4. Lastly, postganglionic parasympathetic fibers innervate the pupillary constrictor muscles 5. Constrictor muscles contract, thereby reducing the size of the pupil.
