Which area of the brain takes over learned, repetitive tasks like riding a bicycle?
Cerebellum
- provides smooth, coordinated body mvmt
Which lobe?
- Voluntary eye mvmt
- Access to sensory data
- Affective response to judgement
- Regulated behavior based upon judgment
- Judgment
- Long-term goals
- Reasoning, concentration, abstraction
Frontal Lobe
Where is the Motor Strip for the opposite side of body located?
Frontal lobe
Where is Broca’s Area?
Frontal lobe
- inferior frontal gyrus
- responsible for MOTOR aspects of speech
What will damage to Broca’s Area cause?
What will damage to auditory center in Temporal lobe cause?
Expressive Aphasia
Receptive Aphasia
Which lobe receives data from skin: pain, heat, cold, pressure?
Parietal
Which lobe processes sensory of spacial awarenes and is used in hand-eye coordination?
Parietal
Which lobe contains the sensory strip for the opposite side of the body?
Parietal
Where is the Auditory center located?
Temporal Lobe
Which lobe has the special senses of taste and smell?
Temporal Lobe
Which lobe?
- Memory
- Understanding Music
- Aggressiveness
- Sexual Behavior
Temporal Lobe
Which lobe is most likely the site of seizure activity?
Temporal Lobe
Which lobe regulates emotion and memory?
Limbic
- involved in formation of long-term memories
- closely associated with olfactory structures
What is the Diencephalon?
posterior part of forebrain that connects the midbrain with the cerebral hemispheres
***encloses the third venticle
What is housed inthe Diencephalon?
Thalamus Hypothalamus Epithalamus Pineal Gland Pituitary Gland
What is referred to as the ‘gateway’ to cerebral cortex and serves as a relay station from sensory inputs to higher levels of brain?
Thalamus
Which area of brain has controls for the following:
- Temp
- Food and Water intake
- Behavior
- Autonomic Responses
- Hormonal Secretion of Pituitary Gland
- Visible Physical Expressions (Limbic System)
Hypothalamus
How many ventricles and what do they contain?
4 total: 2 lateral, 1 central, 1 at bottom of brain
contain CSF
If the longitudinal fissure is not midline, we should suspect what?
increased pressure in one hemisphere shifting it the other way
If the Lateral or Central Fissures look smooth, we should suspect what?
increased pressure
- they should be wrinkled
What are the 12 Cranial Nerves?
I: Olfactory II: Optic III: Occulomotor IV: Trochlear V: Trigeminal VI: Abducens VII: Facial VIII: Vestibulocochlear IX: Glossopharyngeal X: Vagus XI: Accessory XII: Hypoglossal
In the neuro status exam, what is the order of severity?
Alert Confused Delirious Lethargic Obtunded Stuporous Comatose
If pupils have an irregular shape, such as oval-shaped, what should we suspect?
increased pressure on that cranial nerve
