47
Q

what structure is this?

A

aortic hiatus

48
Q

what is the lumbar plexus?

A

set of bilateral nerves made of the ventral rami of T12-L5 spinal nerves

49
Q

what types of axons does the lumbar plexus carry?

A

somatic motor, somatic sensory, and sympathetics to body wall structures

50
Q

do the nerves in the lumbar plexus carry axons from just one spinal cord level?

A

no- carry axons from more than one spinal cord level
*make big nerves out of smaller ones

51
Q

why is the lumbar plexus necessary?

A

the large muscles of the limb need to be more complex and require innervation from multiple spinal nerves
*more efficient to combine the axons supplying large muscles into large nerves

52
Q

why do limb muscles require innervation from multiple spinal nerves?

A

because limb muscles are derived from multiple myotomes

53
Q

flexion of the hip

A

bringing knee closer to chest

54
Q

extension of the hip

A

bringing knee further from chest

55
Q

abduction of the hip

A

moving leg away from midline

56
Q

adduction of the hip

A

moving leg towards the midline

57
Q

ventral rami of spinal nerves carry:

A

somatic sensory
somatic motor
sympathetics to skin

NO PARASYMPATHETICS
