Hyperreflexia
Paresis/paralysis
Disuse atrophy
Babinski
What is the function of the occipital lobe?
Vision
What is the function of the frontal lobe?
Behavior
Executive function
Personality
Motor cortex
What is the function of the temporal lobe?
Hearing
What is the function of the parietal lobe?
Attention
Primary somatosensory cortex
Where do axons from the radial nerve start or terminate at?
Homunculus
What is the function of the cerebellum?
Coordination
Where would the lesion occur if someone had a stroke and is having difficulty with vision?
Posterior cerebral artery
Ataxia
Damage to cerebellum
What does the Brainstem allow you to do?
Breath
What does the Brainstem house?
Nuclei of cranial nerves
What structures make up the Brainstem?
Pons
Midbrain
Medulla
What are the two types of strokes?
Transient ischemic attack
Hemorrhage
What part of the brain does the anterior cerebral artery supply?
Medial frontal and parietal lobes
What part of the brain does the medial cerebral artery supply?
Lateral side of the brain
What part of the brain does the posterior cerebral artery supply?
Lateral frontal and parietal lobes
What are the layers of the brain from internal to external?
Pia mater
Arachnoid mater
Dura mater
What are the functions of the frontal lobe?
Motor output and executive function
What are the functions of the parietal lobe?
Sensory perception
Spatial awareness
Language (left)
What is the function of the temporal lobe?
Auditory perception
What is the function of the occipital lobe?
Vision perception
Precentral gyrus
Primary motor cortex and is responsible for control of voluntary movement
Where is the precentral gyrus found?
Lateral surface of frontal lobe
Post central gyrus
Primary somatosensory cortex
Where is the post central gyrus located?
Lateral side of parietal lobe
What does the central sulcus serve as a boundary between?
Frontal and parietal lobes
What does the lateral sulcus separate?
Temporal lobe from the frontal and parietal lobes
Parieto-occipital sulcus
Separates parietal and occipital lobes
Corpus callosum
Connects each side of the brain and allows them to communicate
What is the function of the hypothalamus?
Homeostasis
What cranial nerves is the midbrain associated with?
3 and 4
What cranial nerve is the pons associated with?
5
What cranial nerves is the medulla associated with?
9,10 and 12
What cranial nerves are associated with the junction between the medulla and pons?
6 and 8
What are the ventricles of the brain responsible for?
Production, transport, and removal of cerebrospinal fluid
Where is the main site for cerebrospinal fluid absorption?
Arachnoid granulations
What does the cerebrospinal fluid provide cushioning for?
Blows to the head
What is the function of the cerebrospinal fluid?
Provides buoyancy that prevents brain from compressing cranial nerves and blood vessels
What is the only way for the cerebrospinal fluid to enter the subarachnoid space?
Apertures
