how many bones make up the vetebral column

33

List another name given for C1, and describe any special characteristics about it.

Atlas it has no body or spinous process. It is comprised of two bony arches with two bony masses laterally. It articulates with the Occiput above and C2 (the Axis) below.

Describe which vertebrae has an anterior arch and a posterior arch.

C1

Describe the divisions of the vertebral column and how many bones are in each division.

Cervical - 7 Thoracic - 12 Lumbar - 5 Pelvic - 9

List two names given for the "toothlike" process that arises from C2.

Dens and odontoid

Describe the structures that help to form vertebral notches.

Depressions located on the superior and inferior surfaces of the pedicle

Describe the laminae and what it helps to form

Flat, broad plates that form posterior part of vertebral arch.

Describe which sections of the vertebral column that are considered primary or secondary curves.

The thoracic and pelvic curves are primary curves. The cervical and lumbar curves develop after birth.

lordosis

abnormal anterior curvature of the lumbar spine

Scoliosis

abnormal lateral curvature of the spine

List another name given for C2, and describe any special characteristics about it,

axis it has a tooth like process called Dens fits into the anterior arch of the atlas above.

Describe which section (s) of the vertebral column that has the most movement + flexibility

cervical and lumbar

Name the vertebrae that has bifid tips on the spinous process and foramen transversarium

cervical vertebrae

Describe which sections of the vertebral column that are considered True vertebrae and which sections are considered False vertebrae.

cervical, thoracic, lumbar have true vertebrae. sacrum and coccyx have false vertebrae.

kyphosis

excessive outward curvature of the spine, causing hunching of the back.

Describe the spinous process and what structures help to form it.

extends posteriorly from the vertebral arch. formed by the laminae.

Describe the superior and inferior articular processes and what anatomic structures help to form them.

facets on the sides of each vertebrae. they form a pillar behind the transverse proccess

Describe the largest of all vertebrae and describe it's spinous process.

lumbar. the spinous process is directly horizontal

Describe the portion of the vertebrae that is known as "little foot ".

pedicles

Describe what lateral masses are, and where they are found.

solid masses of bone that lie one on either side of the vertebral foramen. they support articular facets

vertebral prominens

spinous process of C7

Describe the solid anterior part of a vertebrae.

the body cancellous bone surrounded by compact bone

Describe which divisions of the vertebral column are convex or concave.

the cervical and lumbar spine are convexed. the thoracic and pelvis are concaved.

Describe the curvatures for each division of the vertebral column.

the cervical and lumbar spine are lordotic curved the thoracic and pelvis are kyphosis curved

Describe the curved posterior part of a vertebrae, that encloses an opening

the vertebral foramen

Describe the difference between the vertebral foramen and vertebral canal. What helps to form each?

the vertebral foramen is an opening in a vertebra through which the spinal cord passes. the vertebral canal is formed by the vertebral column and contains the spinal cord and the beginnings of spinal nerves

Describe the transverse process and junction of the two structures that help to form it.

they extend laterally from the junction of the pedicle and the lamina on each side. they come off the body transversely

which vertebrae has costal pits and a caudally inclined spinous process.

thoracic vertebrae

Describe the structures that help to form intervertebral foramen (IVF)

vertebral notches
