Spinal cord

Compression Myelopathy Practice question 1 Which of the following statements is FALSE regarding intraspinal tumors?
	such tumors may arise from within the substance of the spinal cord or compress it from the outside
	they are classified as intramedullary and extramedullary
	extramedullary tumors may be intra- or extradural
	some are dumbbell-shaped
	none of the above are true

Compression Myelopathy Practice question 2 Which of the following statements is TRUE regarding syringomyelia?
	the spinothalamic tracts on both sides are involved in the lesion
	it occurs most often in the lumbosacral cord
	there is a bilateral loss of vibratory sense
	a cape-like distribution of sensory loss can occur
	none of the above are true

Compression Myelopathy Practice question 3 Which of the following statements is TRUE about the dorsal column system?
	a lesion of the most medial part of fasciculus gracilis at spinal level C2 will result in a sensory loss close to the level of the lesion
	a lesion of this system (most commonly in the cervical cord) results in Lhermitte sign upon bending the spine/neck
	lesion results in loss of two point discrimination
	a lesion involving fasciculus gracilis results in a clumsy hand
	two of the above responses are true

Compression Myelopathy Practice question 4 Which of the following statements is TRUE following a lesion of the lateral corticospinal tract?
	there is no spasticity
	following a lesion at C2, the spasticity predominates in the extensors of the upper extremity
	following a lesion at C2, the spasticity predominates in the flexors of the lower extremity
	a Babinski sign is present
	there is considerable muscle atrophy

Compression Myelopathy Practice question 5 Which of the following statements is TRUE?
	a complete transection of the spinal cord at C2 can result in a spastic bladder
	a complete transection of the spinal cord at T10 can result in acute urinary retention
	a large lesion of the cauda equina will result in incontinence
	a lesion of the spinal cord at C2 can result in acute urinary retention
	all of the above statements are true

Compression Myelopathy Practice question 6 Which of the following statements is TRUE?
	a complete transection of the spinal cord at C2 will interrupt all descending pathways involved in the higher control of respiration
	a patient with complete transection at spinal level L5 will not exhibit breathing difficulties
	a patient with complete transection at spinal level L5 could have urinary retention (acute) and a spastic bladder (chronic)
	a patient with a complete transection at spinal level T1 will have a normal functioning diaphram
	all of the above responses are true

Compression Myelopathy Practice question 7 Which of the following statements is TRUE regarding the deficits that would result from the lesion illustrated below?
	damaged axons arise from dorsal horn cells at spinal level T5
	damaged axons arise from dorsal horn cells at spinal level T1
	damaged axons enter the ALS and travel lateral to those carrying information from the big toe
	there is a bilateral loss of pain and temperature from T5 dermatomes
	there is a bilateral loss of pain and temperature from the T5 and below

Compression Myelopathy Practice question 8 Which of the following statements is TRUE regarding the deficits that would result from the lesions (shaded areas) illustrated below?
	the diaphragm would atrophy
	the intercostal muscles will atrophy
	the diaphragm would not help in respiration, but the intercostals would still function in respiration
	a bilateral lesion in the ventral funiculus at C2 would give the same results
	breathing would be normal

Compression Myelopathy Practice question 9 Which of the following statements is TRUE regarding the lesion illustrated below?
	the diaphragm would atrophy
	the intercostal muscles would atrophy
	the diaphragm would not help in respiration
	the patient would die if not put on a respirator
	a unilateral lesion of these pathways does not result in death

Compression Myelopathy Practice question 10 Which of the following statements is TRUE regarding the lesion illustrated below?
	flaccid bladder always occurs
	spastic bladder always occurs
	overflow incontinence always occurs
	urinary frequency and urgency always occurs
	unilateral lesions like this usually do not result in bladder complications

Compression Myelopathy Practice question 11 Which of the following statements is TRUE regarding the lesion illustrated below?
	flaccid bladder
	spastic bladder
	overflow incontinence
	urinary frequency and urgency
	all of the above are true

Compression Myelopathy Practice question 12 Which of the following statements is FALSE regarding results of the lesion illustrated below?
	flaccid bladder
	hyporeflexive bladder
	overflow incontinence
	urinary frequency and urgency
	full bladder sensation would not be perceived
