COMLEX LEVEL 1 PRACTICE QUESTIONS AND
DETAILED SOLUTIONS
◉ Isometric contraction.
Answer: Muscle contraction that results in the increase in tension
without an approximation of origin and insertion. In such a case the
operator's force and the patient's force are equal.
◉ Isolytic contraction.
Answer: Muscle contraction against resistance while forcing the
muscle to lengthen. In such a case the operator's force is more than
the patient's force.
◉ Concentric contraction.
Answer: Muscle contraction that results in the approximation of the
muscle's origin and insertion.
◉ Eccentric contraction.
Answer: Lengthening of the muscle during contraction due to an
external force.
◉ Origin and insertion of anterior and middle scalenes.
,Answer: posterior tubercle of the transverse process of cervical
vertebrae and rib 1
◉ Origin and insertion of posterior scalene.
Answer: posterior tubercle of the transverse process of cervical
vertebrae and rib 2
◉ The _______ will help elevate the 1st rib during forced inhalation..
Answer: anterior and middle scalenes
◉ The _______ will help elevate the 2nd rib during forced inhalation..
Answer: posterior scalene
◉ Alar ligament.
Answer:
◉ The ______ extends from the sides of the dens to the lateral margins
of the foramen magnum..
Answer: alar ligament
◉ The _____ of the atlas attaches to the lateral masses of C1 to hold
the dens in place..
Answer: transverse ligament
,◉ Joint of Luschka (aka uncovertebral joint).
Answer:
◉ The articulation of the superior uncinate process and the
superadjacent vertebra is known as the _________.
Answer: joint of Luschka (aka uncovertebral joint)
◉ Degenerative changes within the joints of Luschka along with
hypertrophy of the intervertebral (facet) joints is the most common
cause of ________..
Answer: cervical nerve root pressure symptoms
