Fundamentals of Medical Neuroscience

Understand the meninges: dura mater, arachnoid mater, and the innermost layer, their spaces including subdural and subarachnoid, plus the falx cerebri, tentorium, and safe lumbar puncture.

Explore the meninges' potential spaces: epidural, subdural, and subarachnoid. Learn how middle meningeal artery injury causes epidural hemorrhage, lens-shaped, and how subdural and arachnoid hemorrhages lead to intracranial bleeding.

Blood fills the subarachnoid space and mixes with CSF, spreading through the space and to the spinal cord, caused by ruptured circle of Willis aneurysms or vascular malformations.

Explore the neural architecture, from grey and white matter and neuron anatomy to receptors and dorsal column pathways for fine touch and proprioception.

Explain the basic nervous system, including motor and sensory neurons, grey and white matter, cranial nerves, and white matter tract classifications such as commissural, association, and ascending and descending tracts.

trace olfactory and optic pathways from nose and retina to cortex, and summarize oculomotor and trochlear control of eye muscles for gaze.

Examine the trigeminal nerve and its three branches—ophthalmic, maxillary, and mandibular—and their sensory and motor roles, alongside the facial and vestibulocochlear nerves for eyes, tears, hearing, and balance.

Explore cranial nerves IX, X, XI, XII—the glossopharyngeal, vagus, accessory, and hypoglossal—and their mixed sensory and motor fibers, parasympathetic roles, and innervation of the tongue, pharyngeal muscles, and neck.

Explore the brain's blood supply, from vertebral arteries forming the basilar artery to the posterior cerebral and cerebellar arteries, and from internal carotid arteries to the anterior circulation.

Trace the internal carotid artery from the aorta through the cavernous sinus to subarachnoid space, noting the ophthalmic artery and the anterior and middle cerebral arteries, and Circle of Willis.

Explore the nervous system's sensory and motor pathways, differentiating special and general, somatic and visceral sensations, their cortical destinations, and autonomic versus somatic motor responses.

Explain visceral sensations and visceral pain, including receptor signaling and reflex pathways via the nucleus of the solitary tract. Map gustatory, olfactory, visual, and auditory processing to cortical areas.

Explore cognitive functions and language, map left-hemisphere brain regions like Broca's and Wernicke's areas, and discuss declarative vs. nondeclarative memory, priming, and conditioning.

Understand how the cortex's frontal, parietal, temporal, and occipital lobes support morality, memory, language, attention, and visual-spatial processing.
