Brainstem-ing
Name the 3 subdivisions of the brainstem.
Midbrain, Pons, Medulla.
Brainstem.
Name each pair of lobes in the cerebral hemispheres.
Frontal, Parietal, Temporal, Occipital.
This portal allows for the flow of CSF between the third and fourth ventricles.
(Cerebral) Aqueduct of Sylvius.
What part of the nervous system includes the 12 cranial nerves?
Peripheral Nervous System.
This is what RAS stands for and what it is responsible for.
Reticular Activating System impacts consciousness and wakefulness.
This organ gives us the awareness of PAIN.
Thalamus.
This lobe assists with motor function, memory, emotions, executive functions and bladder control.
Frontal Lobe.
These are the 2 sets of arteries that supply blood to the brain.
Internal Carotid Arteries and Vertebral Arteries.
This cranial nerve controls pupil constriction, eye opening, and eye movement.
CN III: Oculomotor.
Prior to apnea testing, the oculocephalic (doll's eye) reflex is stimulated to see if function is lost in this part of the brainstem.
Midbrain.
If a patient is having difficulty with their gait, balance, and can't judge stopping distance, this part of the brain is likely affected.
Cerebellum.
These lobes house Wenicke's area that assists with understanding language.
Temporal & Parietal Lobes.
This is the foramen to which EVD transducers are landmarked to be levelled.
Foramen of Monro (before the 3rd ventricle).
If a patient is experiencing vertigo, this cranial nerve may be injured.
CN VIII: Acoustic.
This structure influences the rate and rhythmicity of breathing.
Pons.
Circadian rhythm is regulated in this organ.
Hypothalamus.
These are the primary vessels that supply blood to the occipital lobe.
Middle Cerebral Artery (MCA) and Posterior Cerebral Artery (PCA).
Patients with SAH may develop this type of hydrocephalus if blood is clogging the villi and CSF absorption is inhibited.
Communicating Hydrocephalus.
Bearing down can stimulate this cranial nerve to increase your intra-thoracic pressure and may cause significant hemodynamic changes.
CN X: Vagus.
Apnea testing assesses whether the brain can detect a rise in CO2 and trigger exhalation using these types of receptors.
Chemoreceptors.
This subcortical structure is in charge of fine motor movement and posture.
Basal Ganglia.
If a patient becomes more impulsive, aggressive, or has persistent talking that is more than baseline, what lobe may be affected?
Temporal Lobe.
This circulation path in the Circle of Willis supplies blood to the brainstem and cerebellum.
Posterior Circulation Pathway.
If a patient reports numbness on part of their face, this cranial nerve may be damaged.
CN V: Trigeminal.
