Consists of a large number of nuclei which process motor, sensory, and limbic information and transmit that information to the cerebral cortex.
Thalamus
Receives auditory input from inferior colliculus via the brachium (arm) of the inferior colliculus
Medial Geniculate Body (Nucleus)
Receives visual input from the optic tract
Lateral Geniculate Body (Nucleus)
Receives somatosensory input from the head via trigeminal pathways
Ventral Posteromedial Nucleus (VPM)
Receives somatosensory input from the body via the medial lemniscus and anterolateral system
Ventral Posterolateral Nucleus (VPL)
Receives motor input from basal ganglia
Ventral Anterior Nucleus (VA)
Receives motor input from basal ganglia and cerebellum.
Ventral Lateral Nucleus (VL)
Receives limbic-related input via the mammillothalamic tract and the fornix.
Anterior Nucleus (A)
Much of the pathology of this area has to do with choreoathetoid movements and a disorder called ballismus.
Subthalamic Nucleus
Damage to the pyramid will cause?
Upper motor neuron lesion symptoms
Damage to the cochlear nuclei will cause?
Hearing deficit
Damage to the pyramidal decussating will cause?
Bilateral upper motor neuron lesion deficit
Damage to the oculomotor nerve will cause?
Eye movement deficit
Damage to the hypoglossal nucleus will cause?
Tongue deviated to the ipsilateral side
Damage to the abducent nucleus will cause?
Unable to move ipsilateral eye ball laterally
Damage to the ALS, medial and trigeminal lemniscus will cause?
Contralateral sensory deficit of both face and body
Which controls the internal organs?
- Hypoglossal nerve
- Dorsal Motor Nucleus of Vagus (X)
- Solitary Nucleus
Dorsal motor nucleus of Vagus (X)
Damage to the vestibular nuclei will cause?

- visual deficit
- hearing deficit
- balance deficit
- olfactory deficit
balance deficit
Damage to the motor nucleus of V?

- eye movement deficit
- tongue movement deficit
- uvula movement deficit
- jaw movement deficit
jaw movement deficit
Damage to the spinal trigeminal nucleus/tract?

- ipsilateral face collapsed
- contralateral face collapsed
- ipsilateral face pain and temp deficit
- contralateral face pain and temp deficit
ipsilateral face pain and temp deficit
damange to the medial lemniscus will cause?

contralateral body proprioception deficit
Damage to the mesencephalic tract/nucleus

- face pain and temp deficit
- face tactile deficit
- face/jaw proprioception deficit
- none of the above
face/jaw proprioception deficit
Damage to the facial nucleus will cause?

- unable to close the ipsilateral eye completely
- unable to move ipsilateral eye ball laterally
- unable to stick tongue out ipsilaterally
- unable to stick jaw out ipsilaterally
unable to close the ipsilateral eye completely
Hypoglossal Nucleus & Nerve
Motor innervation of musculature of tongue.

LMNL - tongue deviates toward side of weakness which is SAME side as lesion (IPSI)

UMNL - tongue deviates toward side of lesion which is OPPOSITE side of lesion (CONTRA)
Nucleus Ambiguus
Innervates striated muscles of larynx and pharynx
Provides link between sensory stimuli and emotion
Amygdaloid Nucleus
Primary afferents
Inferior Cerebellar Peduncle

&

Middle Cerebellar Peduncle
Primary efferents
Superior Cerebellar Peduncle
Inferior Cerebellar Peduncle receives:
- spinal cord

- principal olivary & vestibular

- spinocerebellar tract
Middle cerebellar peduncle receives
fibers from pontine nuclei (pontocerebellar fibers)
Cerebral cortex controls cerebellum thru afferent ____
MCP
