facet orientation - upper lumbar

saggittal plane

facet orientation - lower lumbar

saggittal plane and frontal plane

what are the two structure of the disc

nucleus pulposus annulus fibrosis

what happens to the nucleus pulpous

by the end of the first decade the gel begins to be replaced by the end of the first decade by 60 the nucleus fibrosis not distinguished from the annulus fibrous

post lateral ligament in the lumbar spine

its denticulates and this allows for disc herniations in this region post-lat disc herniation

what is myelopathy

compression of the cord

what is radiculopathy

describe pinching of the nerve roots as they exit the spinal cord

what is lumbar spinal stenosis

this is narrowinng of the spinal canal

what is an example of cause of myelopathy

spinal stenosis - this is narrowing of the

what is the function of unisegemtnal muscles

they stablize ajoining vert for the more effective action of the larger spinal muscles

what is the function of the suboccipital muscles

control movement of the skull in nodding and rotation made up of three muscles

what is the function of the erector spinae - longissium

extension and lateral flexion of the spine and neck

what is the function of the mutlifudus

extension of the back

erector spinea - semispinalis

extension and contralateral rot of the spine

what are the typical cervical spine

C3 - C6

what are the atypical cervical spine

C2 C1 C7

what is the transverse foremen

this is for the vert artery

what is the articular pillar

column formed by the sup and inf articular process C2 - C7

where is the intervert foremen located

between the sup and inf noteches of the pedicles

does C1 have body

does C1 have SP

what is the function of the C2 vert

pivot on which the atlas rotates

what is the den

the otontoid process this is found on the axis and is what spins on the atlas

does C2 have a SP

yes large and bifid

does C2 have a TP

yes found underneath the mastoid

What is the function of the long ligament in the cerivcal spine

reinforces the intervert joint

what is the tectorial membrane

the crannial extension of the posterior long ligament

what is the function of the alar ligament

limit axial rotation and lateral bending on the contralateral side, and flexion secondarily

what is the function of the AO joint

nodding

what is the function of AA joint

rotation

what is the function of the transverse ligament

keeping the dens on the C1 during movement

what is the function of the cruciform ligament

prevents abnormal movements of the atlanto-axial joint

where does the cruciform ligament extend to

one up to the occipital bone small band extends down to the body of the axis

what is rot limited by

the alar ligament

what is the total range of the AA joint

what do the scalene attach to

the ribs

scalene medius attachment

1st rib

scalene posterior attachment

2nd rib

what is the function of suboccipital muscle

control movement of the head in nodding and rot

what do we find the subocciptal triangle

vert art C1 DPR - the suboccipital nerve

where does the vert art travel through

C1 - C6 in the transverse canal side of the neck

what are the 5 D's

dipolpia dysphagia dysarrthria drop attack dizziness

what are the 3 N's

nystagmus numbness nausea/vomiting

where is the vert art most vunerable

the subocciptial triangle
