deficit proximal hand
seen with flexion
lumbricals
flexion MCP and extension DIP and PIP
ape hand
unopposable thumb
-median n lesion
atrophy thenar eminence
median n
atrophy hypothenar eminence
ulnar n
ok gesture
prox ulnar n
popes blessing
prox median n
obturator n
L2-L4
injured pelvic surgery
thigh sensation - medial
adduction of leg
obturator n
thigh flexion and leg extension

landmark for local anesthetic for pudendal block
ischial spine

S2-S4
sciatic nerve
L4-S3
posterior thigh innervation
superior gluteal n
gluteus medius and minimus
inferior gluteal n
gluteus maximus
herniation of L3/L4 disc
affect L4 spinal n
herniate posterolateral
thin posterior long ligament and thick anterior long ligament
along midline of vertebral bodies
weak knee extension
loss patellar reflex
L3/L4
patella L4
weak dorsiflexion and difficulty heel walking
L4/L5
weak plantar flexion, difficulty toe walking
loss achilles reflex
S1 is achilles
L5-S1
surgical neck humerus
axilalry
midshaft humerus
radial
distal humerus - cubital fossa
median
popliteal fossa
tibial
posterior to medial malleolus
tibial
muscle contraction
depolarization - down T-tubule
- DHPR - coupled to ryanodine receptor on SR
- release of Ca - from SR
Ca bind troponin C
-tropomyosin moves out of way on actin
myosin release bound ADP and moves to bind actin - power stroke
binding new ATP - detach myosin from actin - myosin cocks head for next contraction
type I muscle
1 slow fat red ox
red - mitochondria and myoglobin
ox phos - sustained contraction
postural mm
type II muscle
fast twich
white
hypertrophy with weight training
cardic m
1 T-tubule and 1 terminal cisternae
diad
skeletal m
1 T tubule and 2 terminal cisternae
