Which parts of the body do the inguinal lymph nodes drain?
Lower limb, perineum, anterior + posterior abdomino-pelvic region
Which parts of the body do the axillary lymph nodes drain?
Upper limb, breast, anterior + posterior thoraco-abdominal walls
Spinal nerve and myotome of the PATELLA TENDON REFLEX
Myotome: Quadriceps
Spinal nerve: L4
Spinal nerve and myotome of the ACHILLES REFLEX
Myotome: gastrocnemius / soleus OR peroneus longus / peroneus brevis
Spinal nerve: S1
Nerves of the lumbar and sacral plexuses
LUMBAR PLEXUS: L1-L4
SACRAL PLEXUS: L4-S3
ILIOHYPOGASTRIC - L1 ILIOINGUINAL - L1 GENITOFEMORAL - L1, L2 LAT. FEMORAL CUTANEOUS - L2, L3 FEMORAL - L2, L3, L4 OBTURATOR - L2, L3, L4 LUMBOSACRAL TRUNK - L4, L5 SUPERIOR GLUTEAL - L4 to S1 INFERIOR GLUTEAL - L4 to S2 SCIATIC - L4 to S3
What is a plica (plural = plicae)?
Reflections / folds of the synovial membrane of the knee joint which may become trapped between the joint surfaces resulting in inflammation and pain
What is the MRC scale and what do the scores mean?
The MRC scale is a way of grading muscle strength (for example if we want to check if the spinal nerve supplying that muscle is still working)
Scores: 0 - no movement 1 - muscle belly moves but joint doesn't 2 - joint moves if gravity is eliminated 3 - joint moves against gravity 4 - joint moves against gravity + some extra resistance 5 - full strength
Myotome of C5 and the reflex used to test it
Myotome - deltoid
Reflex - biceps
Myotome of C6 and the reflex used to test it
Myotome - wrist extensors
Reflex - brachioradialis
Myotome of C7 and the reflex used to test it
Myotome - finger extensors / triceps
Reflex - triceps
Myotome of C8 and the reflex used to test it
Myotome - finger flexors
Reflex - finger flexors
Myotome of T1 and the reflex used to test it
Myotome: finger adductors + abductors
Reflex - none
What are the 2 parts of an intervertebral disc called?
Disc annulus - hard outer bit
Nucleus pulposus - jelly-like inner bit
