- lateral forearm
Term
erb-duchenne palsy
Definition
C5 and C6 roots; limb handing on side, medially rotated, forearm pronated
Term
klumpke palsy and thoracic outlet syndrome
Definition
C8, T1and subclavian artery and inf trunk; atrophy of thenar and hypothenar, atrophy of interosseous, sensory deficits on medial side of forearm and hand, disappearance of radial pulse upon moving head toward ipsilateral side
Term
ulnar claw
Definition
distal ulnar; can't extend 4th and 5th digits
Term
median claw hand
Definition
distal median; loss of lateral lumbrical fxn and can't extend 2nd and 3rd digits
Term
ape hand
Definition
proximal median nerve; can't oppose thumb
Term
klumpke's total claw
Definition
forearm finger flexors and finger extensor are unopposed -> clawing of all digits
Term
long thoracic nerve defect
Definition
serratus anterio -> winged scapula; can abduct above horizontal
Term
thenar and hypothenar mm
Definition
opponens, abductor and flexor
thenar = pollicis
hypothenar = digit minimi
Term
dorsal vs palmar interoseous mm
Definition
dorsal = abduct, palmar = adduct
Term

Definition
flex at MCP and extend PIP and DIP joints
Term
obturator
- injury
- motor
- sensory
Definition
- ant hip dislocation
- adduction
- medial thigh
Term
femoral
- injury
- motor
- sensory
Definition
- pelvic fracture
- thigh flexion and leg extension
- ant thigh and medial leg
Term
common peroneal
- injury
- motor
- sensory
Definition
- trauma to lat leg of fibula neck fracture
- foot eversion and dorsiflexion
- anterolat leg and dorsal foot
Term
tibial
- injury
- motor
- sensory
Definition
- knee trauma
- foot inversion and plantar flexion
- sole of foot
Term
superior gluteal
- injury
- motor
Definition
- post hip dislocation; polio
- thigh abduction -> trendelenburg gait
Term
inferior gluteal
- injury
- motor
Definition
- post hip dislocation
- can't jump, climb stairs, rise from seated position
Term
muscle conduction and contraction
Definition
AP depol -> VG Ca open -> ligand binds mm -> depol travels along T tubule -> dihydropridine and ryanodine recptor on SR -> Ca release from SR -> Ca binds troponin C -> moves tropomyosin out of way -> myosin releases ADP and is displaced on active
Term
type I mm vs type II
Definition
type I = slow twitch, inc mitochondria and myoglobin
type II = fast twitch, white fibers due to dec mito, inc anaerobic glycolysis
Term
skeletal mm contraction mechanism
Definition
Ca binds troponin C -> conf change and tropomyosin moves out of way -> power stroke -> release ADP and ATP binds -> myosin released and cocks
Term
skeletal mm contraction mechanism
Definition
Ca binds troponin C -> conf change and tropomyosin moves out of way -> power stroke -> release ADP and ATP binds -> myosin released and cocks
Term
unhappy triad
Definition
common in football; medial collateral ligament, anterior cruciate ligament, lateral meniscus
Term
abducts arm initially
Definition
supraspinatus
Term
laterally rotates arm
Definition
infraspinatus and teres minor
Term
medialy rotates arm
Definition
subscapularis
Term
adduction of arm
Definition
teres minor and subscapularis
Term
bones of the wrist
Definition
scaphoid, lunate, triquetrum, pisiform, trapezium, trapezoid, capitate and hamate
Term
endochondral ossification
Definition
longitudinal bone growth; cartilaginous model first then osteoclasts and blasts replace with woven bone to remodel to lamellar
Term
membranous ossification
Definition
flat bones; woven bone directly without cartilage; remodeled to lamellar bone
Term
