  • Front

3 parts of a neuron
cell body, dendrite, axon
4 parts of CNS
brain, brainstem, cerebellum, spinal cord
Frontal Lobe
contains primary motor strip and Broca's area. lower boundary is lateral fissure, posterior boundary is central fissure
Parietal Lobe
behind central fissure and above lateral fissure. angular gyrus for naming reading, and writing
Temporal Lobe
bottom 1/3 of each hemisphere. center for hearing; contains primary auditory cortex, Heschl's gyrus, and Wernicke's area
Occipital Lobe
Posterior part of each hemisphere; responsible for vision
primary motor cortex
located in front of central fissure, initiates and controls planned voluntary/controlled movements
primary somatosensory cortex
located behind central fissure, sensation of skin, muscles, joints, and tendons
primary auditory cortex
located behind central fissure, responsible for hearing
primary visual cortex
occipital lobe, vision
primary olfactory cortex
frontal lobe; smell
frontal association cortex
plans and initiates volitional movements
parietal association cortex
processes tactile info and visuospatial info
temporal association cortex
process and discriminate auditory info for language
parieto-occipital association cortex
discriminate and process visual info including reading
primary function of the basal ganglia
receives input from multiple sites in cortex, relays info via thalamus to cortex
primary function of the thalamus
relay center for motor info from motor cortex and sensory info being sent to sensory cortex; receives input from many sources; regulates electrical activity and maintains alertness/attention
Causes of Adult Communication Disorders
stroke, intracranial tumor, hydrocephalus, infection, toxemia, metabolic disorders, nutritional disorders, TBI
Trigeminal Nerve (V)
Opens and closes jaw; both
Facial (VII)
controls muscles used in facial expressions; both
Vestibulocochlear nerve (VIII)
controls hearing, balance, and position sense; both
Glossopharyngeal nerve (IX)
controls the muscles in the tongue in swallowing; both
Vagus (X)
controls soft palate, base of tongue, pharynx, and larynx; both
Spinal Accessory nerve (XI)
controls movements of the neck and shoulders; motor
Hypoglossal nerve (XII)
allows tongue to protrude, retract, and curl; motor
Parts of a Neurologist Exam
Interview of patient/family, Neurological Exam, and Laboratory Tests
Radiologic Imaging Studies
Cerebral angiography, CAT scan, MRI, and echo arteriography and transcranial doppler ultrasound
Nonradiologic Imaging Studies
rCBF, PET, EEG, and Evoked Cortical Potentials
