Cerebellum
What are ataxia and balance deficits?
This is the name of the crossing fibers of the lateral corticospinal tract.
What is the pyramidal decussation?
This gray matter contains the cell bodies for all peripheral afferent nerve cells.
What is the dorsal root ganglion?
This NT has an inhibitory effect wherever it appears in the basal ganglia
What is GABA?
This type of motor control deficit is characterized by non-velocity dependent resistance to passive stretch of both agonist and antagonist.
What is rigidity?
This layer of the cerebellum includes Purkinje cell bodies and interneurons
What is the cortical/gray matter?
This second order pathway carries information from the nucleus gracilis and cuneatus to the ventral posterolateral nucleus of the thalamus.
What is the medial lemniscal pathway?
This gray matter and location contain the cell bodies of the alpha motor neurons.
What are the anterior horn cells in the anterior horn of the spinal cord?
This NT is found at the neuromuscular junction
What is acetylcholine?
This visual pathology is most likely to lead to left neglect syndrome.
What is left homonymous hemianopsia?
These two pathways both have output from the cerebellum.
This portion of the anterolateral pathway carries information relating to pain and arousal
What is the spinoreticular pathway?
This gray matter and location are where the second order neurons of the DCML from the lower extremities synapse.
What is the nucleus gracilis in the caudal medulla?
The release of this NT from the subthalamic nucleus causes the globus pallidus internus to inhibit the thalamus
What is glutamate?
This phenomenon occurs when there is damage to an axon; axon fibers and target cells deteriorate distal to the injury.
A lesion in this location will cause specifically truncal ataxia
What is the vermis?
This connection in the brainstem communicates vestibular information to the superior colliculi to help mediate the vestibulo-ocular reflex
What is the medial longitudinal fasciculus?
This gray matter and locations contains cell bodies that mediate our fight or flight response
What are the sympathetic ganglia lateral to T1-L2?
This NT is a mediator of pain and inflammation
What is substance P?
Bleeding into this area of the meninges is a medical emergency and can cause a thunderclap headache, sudden unconsciousness and death.
What is the epidural space?
A lesion in this location will cause specifically right sided extremity ataxia.
What is the right intermediate and lateral cerebellar hemispheres?
This portion of the anterolateral pathway synapses in the periaqueductal gray matter and carries information influencing our emotional response to pain.
What is the spinomesencephalic pathway?
This gray matter in the brainstem has six pathways leading away from it, including the medial longitudinal fasciculus.
What is the vestibular nuclei?
This NT, critical for mood, sleep and appetite, is released from the raphe nuclei of the brainstem.
What is seratonin?
This connection between the occipital and parietal lobe is also sometimes called the "where" pathway.
What is the dorsal stream?
