Quiz 4 Flashcards
spine regions
cervical region, thoracic region, lumbar region, and sacrum and coccyx
what is the non movable portion of the spine
the sacrum and coccyx are apart of the pelvic girdle and non movable region of the spine
what are the three regions of the movable spine
the cervical region, thoracic region, and lumbar region
where does the cervical region of the spine attach
to the head
where does the thoracic region attach
to the rib cage
where does the lumbar region attach
to the pelvis
What is the primary curve of the spine
the thoracic region because it is found in babies
What is the secondary curve of the spine
they develop later in the cervical and lumbar regions
what is the benefit of curves in the spine
they help absorb shock
what is the primary curve also known as
Kyphotic
what is the secondary curve also known as
Lordotic
What are the structural components of the vertebrae
body, spinous processes, superior articulating facets, and inferior articulating facets
Specialized vertebrae
sacrum, coccyx, atlas (C1), axis (C2), and 7th cervical vertebra
what is technically considered a joint in the spine
any articulation between 2 vertebra
special joint of the spine
lumbosacral, atlantoaxial, atlantooccipital
what is the lumbosacral joint
the sacrum with the 5th lumbar
what is the atlantoaxial joint
the atlas with the axis
what is the atlantooccipital
the atlas with the occipital
ligaments of the spine
anterior longitudinal ligament, posterior longitudinal ligament, supraspinous ligament, and the nuchial ligament
what are the costal facets
costal facets are additional facets of the thoracic vertebrae
how are the ribs numbered
like the thoracic vertebrae 1-12
actions of the spine on the sagittal plane
flexion and extension
actions of the spine on the frontal plane
right lateral flexion and left lateral flexion
actions of the spine in the transverse plane
rotation to the right and rotation to the left
how is rotation of the spine determined
the position of the shoulders in relation to the hips
where does movement of the spine occur
between all the bones in the movable spine
positions of the spine in the sagittal plane
flexion, extension, and hyperextension
positions of the spine in the frontal plane
right lateral flexion, left lateral flexion, and neutral
positions of the spine in the transverse plane
right rotation, left rotation, and neutral
