a small, smooth, flat surface on the bone

  • they are found in the thoracic spine at the point of contact at a rib
A

Facets

27
Q

The curves of the spine provide stability as if the spine were a straight rod, the spine would not be stable at all

  • In fact, the strength is _______times what it would be if the spine were straight
A

10x

28
Q

this is the articulation between the superior articular process with the inferior articulate process of the vertebra above

A

A facet joint

29
Q

Motions occur in all three planes of motion in the spine

A

Flexion/extension
Abduction/adduction (side bending)
Rotation

30
Q

Motion at the Occiput and C1 is called?

A

the atlanto-occipital joint

  • Main motion is flexion and extension
31
Q

Most of the lateral flexion and rotation in the spine occurs where?

A

at C1 and C2 or the atlanto-axial joint

32
Q

Muscles that have the most influence on O/C1 and C1/C2 are what ?

A
  • prevertebral muscles anteriorly
  • suboccipitals posteriorly
33
Q

Tucking your chin and neck extension is cervical ?

A

retraction

34
Q

Extending your head and flexing your head is cervical what?

It’s the pigeon bob – forward is protraction, backwards is retraction

A

protraction

35

60
Q

extends from C7 distally to the sacrum posteriorly along the tips of the spinous process

A

Supraspinal ligament

61
Q

connects adjacent laminae anteriorly

A

Ligamentum flavum

62
Q

Fun Facts

  • The lumbar spine is the region of the body most often injured due to its mobility and the location of the center of gravity
  • The thoracic spine has much less ROM due to the attachments of the rib cage
  • The cervical spine is freely mobile – allows for freedom of motion, allows for entrance and exit of the blood vessels in the skull
A

fun
