22
Q

whats a myotome?

A

same as dermatome - but for motor movement

23
Q

lumbosacral plexus:

which major nerves come from the lumbar plexus? [3] what are nerve roots?

A

which major nerves come from the lumbar plexus? [3]
femoral nerve: L2, L3, L4
obturator nerve: L2, L3, L4
lateral cut. nerve of thigh: L2 & l3

24
Q

femoral nerve provides motor supply to which compartment of thigh? [1]
what movement does this cause? [2]
main muscles of anterior [3]

A

femoral nerve provides motor supply to which compartment of thigh? [1]
anterior

what movement does this cause? [2]
flex hip
extend knee

main muscles for ^?
quadriceps
sartoruis
iliopsoas

25
what can damage femoral nerve? [3] basic understanding x what would damage to femoral nerve cause? movement wise xo
_what can damage femoral nerve? [3]_ •Compression – from treatment for congenital hip dysplasia •Pelvic fractures •Anterior hip dislocations (very very rare) _what would damage to femoral nerve cause?_ - paralysis of quadriceps - sensory loss to anterior thigh
26
**obturaror** nerve provides motor supply to which compartment of thigh? [1] what movement does this cause? [1] main muscles of this? [1]
* *obturaror** nerve provides motor supply to which compartment of thigh? [1] * *medial compartment** what movement does this cause? [1] **adduction of thigh** main muscles of this? [1] **adductors**
27
lateral cutaenous nerve occurs from which Vert levels? [2] what is role? [1]
lateral cutaenous nerve occurs from which Vert levels? [2] **L2 & L3** what is role? [1] sensory innervation to lateral aspect of thigh
28
which three nerves arise from sacral plexus? [3]
_which three nerves arise from sacral plexus? [3]_ •Sciatic nerve (Tibial and common peroneal nerves) •Superior gluteal nerve •Inferior gluteal nerve
29
30
sciatic nerve provides motor supply to which compartment of thigh? [1] what movement does this cause? [2] main muscles of this compartment [3]
_sciatic nerve provides motor supply to which compartment of thigh? [1]_ **posterior compartment** _what movement does this cause? [2]_ **extend hip flex knee** _main muscles of this compartment [3]_ •Semitendinosus •Semimembranosus Biceps femoris (long head
31
what are the 3 muscles compartments of the leg (knee - foot) what are the muscle movements each compartment do?
32
33
Posterior compartment of leg: - two compartments of postior? [2] - innervation? [1] - movement? [2] - blood supply? [1]
Posterior compartment of leg: - two comparments: **superficial & deep** - innervation: **tibial nerve** - movement: **plantar flexion, flexion of digits** - blood supply: **posterior tibial artery**
