And Way Down We GO (Descending Tracts)
Muscles that are innervated by LMNs that synapse with medial UMNs.
What are postural and girdle muscles?
The number of neurons that ascending tracts typically involve.
What is 3?
I am the location of the columns for the Spinothalamic tracts.
What is anterolateral?
Parasympathetic response to high BP is triggered by these receptors.
What are baroreceptors?
I receive info about head movement/position from the vestibular appparatus.
What is the Medial Vestibulospinal Tract?
I am where the crossing for the DCML occurs.
What is the lower medulla?
I am where the 3rd neuron synapses for the spinothalamic pathway for the body.
What is the VPL of thalamus?
Preganglionic nerves travel through this cranial nerve to synapses in ganglia in parasympathetic efferent innervation to the heart.
What is the vagus nerve?
The percent of lateral corticospinal tract axons that cross to the contralateral side at the pyramids of the medulla.
What is 88%?
I am the 2nd order neuron for the DCML of the LOWER body.
What is the nucleus gracilis?
I am where decussation occurs for the trigeminothalamic/spinothalamic tract for the face.
What is the lower medulla?
Sympathetic efferent preganglionic neurons enter the sympathetic chain via these.
What are white ramus communicans?
I am where the rubrospinal tract originates.
What is the red nucleus of midbrain?
I am the 3rd order neuron for the DCML pathway from the face.
What is the VPM nucleus of thalamus?
I transmit slow pain information to the superior colliculus and the periaqueductal gray.
What is the spinmesencephalic tracts?
Parasympathetic efferent postganglionic nerves terminate here?
What are the SA node, AV node, and musculature of the heart?
I am the neurotransmitter that the raphespinal tract releases.
What is serotonin?
I am the somatotopic organization of DCML for the LE in the spinal cord.
What is medial?
I am where the first neuron of the dorsal spinocerebellar pathway synapses.
What is nucleus dorsalis (Clarke’s nucleus)?
I am the muscle that gets activated at the end of the sympathetic pathway of pupil dilation by postganglionic fibers that join long ciliary nerves.
What is the dilator papillae?
