1Sensory 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.
- Amedial
2Which of the following pictures correctly identifies Brown-Séquard syndrome?
- A1
- B2
- C3
3Spinocerebellar tracts provide unconscious proprioceptive information to the cerebellum. Do their tracts provide contralateral or ipsilateral information to the cerebellum?
- AIpsilateral
- BContralateral
4The [blank_start]corticobulbar[blank_end] tracts of the pyramidal system contain the upper motor neurone of the cranial nerves.
- Acorticobulbar
5Lesions 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- ALower motor neuron lesion
- BUpper motor neuron lesion
6Bell's Palsy is a lesion of the Facial nerve's [blank_start]lower[blank_end] motor neuron
- Alower
- Bupper
7In terms of the extrapyramidal tracts:
The Vestibulospinal tract originates from the vestibular nucleus in the [blank_start]pons[blank_end].- Apons
8The 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- APontine reticulospinal tract
- BMedullary reticulospinal tract
9The rubrospinal tract is responsible for exciting flexor muscles and inhibiting extensor muscles of the upper body
- AVerdadero
- BFalso
10The tectospinal tract originates from ...
- ASuperior colliculus of the midbrain
- BInferior colliculus of the midbrain
11Which is the only vertebrae not to have a spinous process or body?
[blank_start]C1[blank_end]- AC1
12In 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.
- Aflavum
13A 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]- Ayoung
- Belderly
- CL4
- DL3
14The sciatic nerve runs from spinal levels L[blank_start]4[blank_end]-S[blank_start]3[blank_end]
- A4
- B3
15Sciatica pain is typically exaggerated by coughing/sneezing
- AVerdadero
- BFalso
16In 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- AAnkle Jerk
- BKnee Jerk
17Cauda equina syndrome most commonly occurs due to a midline disc herniation at which vertebral level?
- AL3/4
- BL4/5
- CL5/S1
18A 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.
- AVerdadero
- BFalso
19If symptoms are tolerable and the walking distance is not significantly affected then conservative treatment should be offered before any surgical intervention.
- AVerdadero
- BFalso
20In terms of Cervical Myelopathy, decompressive spinal surgery should only be offered following a trial of analgesia and physiotherapy.
- AVerdadero
- BFalso
21How does Brown-Sequard Syndrome present?
- AWeakness/paralysis on one side of the body and loss of sensation on the opposing side
- BWeakness/paralysis unilaterally
- CParalysis of both lower limbs
- DWeakness/paralysis and loss of sensation only on one side of the body
