cervical lumbar spin

cervical lumbar spine

QuestionAnswer
how is the spinal canal formed by openings in vertebrae when stacked upon each other
where does the spinal canal begins and ends at begins at the base of the skull & extends distally to the sacrum.
what contains the cerebrospinal fluid the spinal canal
where does the spinal cord begins & ends at begins at the medulla oblongata,passes through the foramen magnum & ends at the lower border of the 1 lumbar vertebrae.
where is the most common place for a lumbar puncture L3-L4
how many vertebrae are in cervical,thoracic,lumbar,sacrum & coccyx 7cervical,12thoracic,5lumbar,1sacrum,1coccyx
the sacrum is fused from 5 into how many 1 sacrum
the coccyx is fused from 3 to 5 into how many 1 coccyx
the cervical & lumbar regions have concave curves and are called lordotic
the thoracic & sacral regions have what kind of curves convex curves
when does the thoracic & sacral curves develop soon after birth
what are the primary or posterior curves the thoracic & sacral curves
which two portions of the vertebral column are classified as 2nd or compensatory curves cervical & lumbar
when is the first compensatory curve formed formed in the cervical region when a child begins to hold up his head
when is the 2nd compensatory curve formed formed in the lumbar region when a child first learns to walk
what is the body of the vertebrae is the thick weight bearing part of the vertebrae
the vertebral arch extends where extends posteriorly from the body
what are the intervertebral joints the slightly moveable joints b/w the vertebral bodies
the posterior body & arch form an opening called the vertebral foramen
what protects the spinal cord the spinal canal
how is the vertebral canal formed when vertebra are stacked
the pedicles extend how posteriorly from each side of the vertebral body
the pedicles extend posteriorly from each side of the vertebral to form what they form most of the sides of the vertebral arch
the posterior portion of the vertebral arch is formed by the laminae
the transverse process extends laterally from where the junction of the pedicles & laminae
the spinous process extends posteriorly from--- union of the two lamina
the zyagopophseal joints are form by the sap(superior articulating process) & iap (inferior articulating process facets are actual articulating surfaces
on each vertebrae there is a superior vertebral notch and inferior vertebral notch located above & below each pedicle forming the intervertebral foramina(l&R)
fibrocartilaginous disks are located b/w each vertebrae except C-1 & C-2
each disk contains an outer fiberous portion called and the inner portion is called annules fibrosis,nucleus pulposus
C-3 & C-6 have what kind of characteristics all the same characteristics
what are the 3 unique features(characteristics) of cervical vertebrae bifid tip,transverse foramen,overlapping bodies
the chunks of bone b/w the superior & inferior articular processes are called articular pillars
the term lateral mass is used when describing the pillar for what C-1
C-7 vertebrae prominens has many features of the thoracic vertebrae
the transverse atlantal ligament holds the dens or odontoid process in place
C-1 has no what no body
what forms the atlantoocciptal joints the superior articulating processes of C-1 have a large depressed surfaces for articulation with the occiptal condyles of the skull
Axis or C-2 contains what contains the dens or odontoid process
what is the function of the dens acts as a pivot for the rotation of the head
zygapopyseal joints b/w atlas & axis are only seen on a what true AP projection
the intervertebral foramina are located at what 45 degrees angle to the MSP
what are the normal thoracic vertebrae T5,T6,T7,T8
T1-T4 have what characteristic characteristic of cervical vertebrae
T9 thur T12 have what kind of characteristics characteristic of lumbar vertebrae
what is the unique features of thoracic vertebrae facets for articulation w ribs.spinous process of thoracic vertebrae extend extremely inferior so the spinous process of T4 will be superimposes on the body of T5 during an AP
the articulation b/w the transverse processes of the thoracic vertebrae & the tubercle of each rib forms the costotransverse joint
11 ribs & 12 ribs do not have costotransverse but articulates at what costovertebral joints
