SIEMENS LEVEL ONE EXAM 2026 COMPLETE
STUDY GUIDE SOLVED QUESTIONS
◉ What is a sclerotome. Answer: segment of the somite that gives
rise to bone/skeletal tissue
each sclerotome is supplied by a single nerve root
◉ What is odontoidium. Answer: Failure of fusion between dens and
body of axis
◉ When does the apical ossification centre develop between the
odontoid process and body of axis?. Answer: Age 3
◉ Consequences of odontoidium. Answer: CV laxity if not ossified by
second decade of life
◉ Do true myotomes exist in the limb and why. Answer: No
Segmental muscles and their nerves fuse with adjacent muscles
◉ Where do true myotomes exist. Answer: Spine
,◉ Examples of true myotome muscles. Answer: Suboccipitals
Rotatores
Multifidus
◉ Motor fibres are exit the spinal cord via the. Answer: Ventral root
◉ Sensory fibres enter the spinal cord via the. Answer: Dorsal root
◉ Where/what level do each of the nerve roots exit the spinal cord.
Answer: C1-C7: above the corresponding vertebrae
C8-below: below the corresponding vertebrae
◉ 4 lobes of the cerebrum. Answer: Frontal - motor, thought speech,
attention
Parietal - touch/proprioception
Occipital - vision
,Temporal - hearing, memory
◉ Motor area lesion consequences. Answer: paralysis - primary
motor area
apraxia - motor association areas
◉ What are the motor association areas. Answer: supplementary
motor area
- motor maps for posture
premotor area
- higher order processing/integration of motor info
◉ Where is the primary somatosensory area located. Answer: post-
central gyrus of parietal lobe
somatotropin organization of sensory information
◉ Sensory area lesion consequences. Answer: primary area - poor
localization of sensory stimuli
, Sensory association area
- tactile agnosis (significance)
- asterognosis (recognize objects)
◉ Sensory association area location. Answer: adjacent to
somatosensory area
- significance
- proprioception
◉ Right parietal lobe lesions. Answer: left spatial neglect
◉ Temporal association area lesion. Answer: leads to agnosia
can't recognize
◉ frontal association area lesion. Answer: personality changes
◉ Motor cortex location and function. Answer: Posterior frontal lobe
movement production
