Description

Neurosurgery Module 1 - Spine from Delta. I have only included questions on topics I feel need revisited/were not covered in lectures.

Resource summary

Question 1

Question
Sensory afferents of the dorsal column pathway, after passing the medulla, decussate to the contralateral [blank_start]medial[blank_end] lemniscus before eventually synapsing in the thalamus.
Answer
  • medial

Question 2

Question
Which of the following pictures correctly identifies Brown-Séquard syndrome?
Answer
  • 1
  • 2
  • 3

Question 3

Question
Spinocerebellar tracts provide unconscious proprioceptive information to the cerebellum. Do their tracts provide contralateral or ipsilateral information to the cerebellum?
Answer
  • Ipsilateral
  • Contralateral

Question 4

Question
The [blank_start]corticobulbar[blank_end] tracts of the pyramidal system contain the upper motor neurone of the cranial nerves.
Answer
  • corticobulbar

Question 5

Question
Lesions of the facial nerve: [blank_start]Upper motor neuron lesion[blank_end] = Paralysis of lower half of one side of the face only - forehead muscles remain intact [blank_start]Lower motor neuron lesion[blank_end] = Paralysis of one half of the face including forehead muscles
Answer
  • Lower motor neuron lesion
  • Upper motor neuron lesion

Question 6

Question
Bell's Palsy is a lesion of the Facial nerve's [blank_start]lower[blank_end] motor neuron
Answer
  • lower
  • upper

Question 7

Question
In terms of the extrapyramidal tracts: The Vestibulospinal tract originates from the vestibular nucleus in the [blank_start]pons[blank_end].
Answer
  • pons

Question 8

Question
The reticulospinal tracts originate from the reticular formation and control tone. [blank_start]Pontine reticulospinal tract[blank_end]: facilitates voluntary/reflex responses and increases tone [blank_start]Medullary reticulospinal tract[blank_end]: inhibits voluntary/reflex responses and decreases tone
Answer
  • Pontine reticulospinal tract
  • Medullary reticulospinal tract

Question 9

Question
The rubrospinal tract is responsible for exciting flexor muscles and inhibiting extensor muscles of the upper body
Answer
  • True
  • False

Question 10

Question
The tectospinal tract originates from ...
Answer
  • Superior colliculus of the midbrain
  • Inferior colliculus of the midbrain

Question 11

Question
Which is the only vertebrae not to have a spinous process or body? [blank_start]C1[blank_end]
Answer
  • C1

Question 12

Question
In terms of vertebral anatomy, the ligamentum [blank_start]flavum[blank_end] runs vertically connecting the lamina of adjacent vertebrae. It helps maintain an upright posture and assist straightening the spine after flexion.
Answer
  • flavum

Question 13

Question
A lumbar disc herniation is more likely to occur in [blank_start]young[blank_end] patients, due to a strain on the spine (e.g. lifting heavy load). The most common type of disc herniation is a paramedian herniated disc. If a paramedian herniated disc was to occur at the L3/4 level, which nerve would be affected? (L3 or L4) [blank_start]L4[blank_end]
Answer
  • young
  • elderly
  • L4
  • L3

Question 14

Question
The sciatic nerve runs from spinal levels L[blank_start]4[blank_end]-S[blank_start]3[blank_end]
Answer
  • 4
  • 3

Question 15

Question
Sciatica pain is typically exaggerated by coughing/sneezing
Answer
  • True
  • False

Question 16

Question
In the case of an L5/S1 prolapsed intervertebral disc where the S1 root is involved, which reflex would you expect to be absent? [blank_start]Ankle Jerk[blank_end] Reflex
Answer
  • Ankle Jerk
  • Knee Jerk

Question 17

Question
Cauda equina syndrome most commonly occurs due to a midline disc herniation at which vertebral level?
Answer
  • L3/4
  • L4/5
  • L5/S1

Question 18

Question
A PR exam should be conducted only where necessary in a potential Cauda Equina Syndrome patient, as such an invasive exam may worsen the patient's prognosis.
Answer
  • True
  • False

Question 19

Question
If symptoms are tolerable and the walking distance is not significantly affected then conservative treatment should be offered before any surgical intervention.
Answer
  • True
  • False

Question 20

Question
In terms of Cervical Myelopathy, decompressive spinal surgery should only be offered following a trial of analgesia and physiotherapy.
Answer
  • True
  • False

Question 21

Question
How does Brown-Sequard Syndrome present?
Answer
  • Weakness/paralysis on one side of the body and loss of sensation on the opposing side
  • Weakness/paralysis unilaterally
  • Paralysis of both lower limbs
  • Weakness/paralysis and loss of sensation only on one side of the body
