MSK/OPP Comlex exam with complete
solutions 2024/2025
for FPR and CS.
Decreased gamma gain to muscle spindle:
Cervical sensory
Read More
supine, E hip + Adduct
ME inf pubic shear:
heavy P.
Meissner corpuscle:
Vibration.
Pacinian corpuscle:
heavy touch.
Merkle disc:
stretch.
Ruffini end organ:
1) Aff sensory neurons in intrafusal muscle -> CNS. 2) Alpha motor neurons from
spinal cord -> Agonist muscle (contract) and inhibit Antagonist muscle (relax). 3)
Gamma motor neuron from spinal cord -> continued "Gamma Gain" of intrafusal
fiber as muscle shortens to finish contraction.
Muscle load phys:
highly excitable spinal segment: less aff stimulation required to stimulate the
nerve, higher resting membrane potential, hyper-excitable neural state.
Facilitation:
something that should hurt, hurts.
Allodynia:
pain OOP.
, Hyperalgesia:
required to get AP to fire, and once fired, AP goes to max intensity. Patellar reflex
gets hyper-reflexive.
Hyperpathia:
above C7
C7 nerve root exits:
below C7
C8 nerve root exits:
below T1.
T1 nerve root exits:
wrist drop (radial n).
C7 motor reflex:
Motions of OA/AA/C2-7
First Real Segment = FRS
Down Syn, RA b/c AA instability (weak Alar and Transverse lig).
CI to Cervical tx:
L1-3, Rib 6-12.
Diaphragm attachments:
1-2, 11-12.
Atypical ribs:
ATF (Ant-Talobfib).
Lig torn in Inversion ankle:
1=1, 2=2, 3=3.
Type 1-3 Ankle sprain:
Pronate Ankle, Post Talus (opp fib).
Ant Fib Head:
Supinate Ankle, Ant Talus (opp fib).
Post Fib head:
Iliolumbar (stabilize ant motion of L5 on pelvis)
First lig injured w/innominate SD:
separate G/L sciatic F.
Sacrospinous lig:
Ab, EROT. N S1-2. Attach Ant Ant Sacrum - Sup G Troch. Sciatic n run under
piriformis -> post thigh -> foot.
Piriformis anat:
Main Hip Flexor.
Iliopsoas action:
Craniosacral and repriatory motion.
Superior sacral axis:
postural motion.
Medial sacral axis:
