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
|
|

|
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
|
|
