Vestibular
respond to head movement (turning) by detecting angular acceleration
What are the semicircular canals?
The main output cells from the cerebellar cortex
What are Purkinje cells?
Makes up 80% of the diencephalon
What is the thalamus?
What are Trigeminal, Glossopharyngeal, vagus, hypoglossal and facial
Part of the brain responsible for autonomic, endocrine, emotional and somatic functions
What is the hypothalamus?
The eyes are driven to edge of orbit (slow phase), and then reverse direction rapidly (quick phase).
What is right nystagmus?
The functional division of the cerebellum involved in muscle tone and postural control, especially of the limbs
What is the spinocerebellum?
Function of the ventral posteriolateral nucleus
What is somatosensory relay from the body?
Cranial nerves involved in pharyngeal phase of swallowing
What are Glossopharyngeal and vagus?
Thalamic nuclei responsible for regulation of thalamic activity
What is the reticular nucleus
Projections from spinal cord to the vestibular nuclei
What are spinovestibular fibres (traveling with the posterior spinocerebellar tract) carrying info about posture and body orientation?
Arise from the contralateral inferior olivary nucleus and are thought to be involved with motor error signals and motor learning
What are climbing fibers?
Afferents of the pulmonary and lateral posterior nuclei
What are the retina and superior colliculus?
Assessing facial symmetry, taste and saliva production are assessing this nerve
What is Facial?
The structure that is damaged in someone with diabetes inspipidus
What is a lesion to the hypothalamus?
Displaced otoliths from the utricle or saccule in the semi circular canal leading to inappropriate firing of the vestibular nerve
What is benign paroxysmal positional vertigo?
The functional division of the cerebellum that receives the corticopontocerebellar pathway from the contralateral cortex
What is the neocerebellum?
Damage to posterior thalamus
What is thalamic pain syndrome where somatosensory stimuli causes pain.
Dysarthria, Ataxia of tongue and difficulty moving food in the mouth are results of impairment to this cranial nerve.
What is Hypogossal?
Hormones produced in the thalamus that are released from posterior lobe of pituitary gland
What are oxytocin and ADH (Antidiretic hormone)
Positive Romberg sign and what it is due to
When a person stands with feet together and eyes closed they sway or fall, due to proprioceptive deficits.
results from damage to lateral hemispheres of the cerebellum. Motor problems occur ipsilaterally (decrease in tone, reduced stretch reflexes, problems in coordination of voluntary movements)
What is posterior lobe syndrome?
The afferent and efferent of the Anterior thalamic nuceli
What is the mamillothalamic tract (afferent) and the efferent to the cingulate gyrus
The role of glossopharngeal cranial nerve in the oral preparatory phase of swallowing
What is salivation and taste from the posterior 1/3 of tongue?
Frontal ataxia, loss of equilibrium, staggering wide based gait.
Results of medulloblastoma which is damage to the floculonodular lobe of cerebellum
