What is superior and inferior to the vertebral body?

From superior to inferior, these are: Cervical: 7 vertebrae (C1 = highest; C7 = lowest) Thoracic: 12 vertebrae (T1 = highest; T12 = lowest) Lumbar: 5 vertebrae (L1 = highest; L5 = lowest)

What is vertebral epiphysis?

Unlike other long bones of the skeleton, vertebral body epiphyses never ossify, and after the end of the growth period of life they are reduced into thin plates of hyaline cartilage which are situated between vertebral body and intervertebral disc.

What is the superior vertebra?

The superior, or upper tubercle is the mammillary process which connects with the superior articular process. The multifidus muscle attaches to the mammillary process and this muscle extends through the length of the vertebral column, giving support.

Where are the growth plates in the spine?

Growth plate cartilage, which is located at each end of the vertebral body, plays a pivotal role in promoting longitudinal spinal growth in humans and other mammals8, 10, 11, 12.

Which region of the vertebral column is located superior?

cervical region
The cervical region of the spine is the most superior and contains seven small vertebrae. The main function of the cervical region is to facilitate attachment of the skull to the spine, protect the spinal cord over the exposed neck and shoulder region, and support the body.

What is the most superior bone of the vertebral column?

cervical vertebrae
The cervical vertebrae are the smallest and most superior of the vertebrae. The most superior of these vertebrae articulate with the skull. The thoracic vertebrae are matched to each pair of ribs to form the rib cage and establish the thoracic cavity.

What attaches to the epiphyseal ring?

The main function of the ring is to anchor the external fibers of the anulus fibrosus to the vertebral body. Initially, the osseous rim is separated from the vertebral body by a cartilaginous layer, but at age 14 or 15, fusion of the bony rim and the vertebral body occurs.

Where is the superior vertebral notch?

superior vertebral notch (Incisor vertebralis superior) is a slight indentation on the superior surface of the pedicle.

What is the epiphyseal plate?

The growth plate, also known as the epiphyseal plate is a thin layer of cartilage that lies between the epiphyses and metaphyses, and is where the growth of long bones takes place.

Are there growth plates on vertebrae?

From childhood, vertebrae grow through thin growth plates on the superior and inferior vertebral end-plates and from neuro-central, articular process and spinous process synchondroses [21–23].

Which region of the vertebral column is located superior to the thoracic region in which region is inferior to the thoracic region respectively quizlet?

Which region of the vertebral column is located superior to the thoracic region and which region is inferior to the thoracic region, respectively? Superiorly: cervical and inferiorly: lumbar.

Which region of the vertebral column is located inferior?

Inferiorly, C1 articulates with the C2 vertebra, and so on. Below these are the 12 thoracic vertebrae, designated T1–T12. The lower back contains the L1–L5 lumbar vertebrae. The single sacrum, which is also part of the pelvis, is formed by the fusion of five sacral vertebrae.

What is the correct order of the vertebral regions from superior to inferior?

So, the correct answer is ‘Cervical, thoracic, lumbar, sacral’.

Which region of the vertebral column is immediately superior to the lumbar region?

Which region of the vertebral column is immediately superior to the lumbar region? Which region of the vertebral column is immediately inferior to the lumbar region? The sacrum is located below the lumbar region, articulating superiorly with L5 and inferiorly with the coccyx.

What is vertebral ring?

The ring apophysis is a secondary ossification center of the vertebral endplate connected to the intervertebral disc. It is firmly attached to disc fibrous annulus through Sharpey fibers and its ossification occurs at 4-6 years old.

Where is the vertebral endplate?

Vertebral endplates are located between vertebrae (bones of the spine) and intervertebral discs (gel-filled structures that protect and cushion the vertebrae). They consist of a layer of cartilage and a layer of porous bone.

What is superior vertebral notch?

Superior vertebral notch are the concavities on the superior aspect of the pedicle. When the vertebrae are articulated, the inferior and superior notches of each contiguous pair of bones form the intervertebral foramina.

What is the epiphyseal rim of vertebral endplate?

A vertebral endplate consists of the epiphyseal rim, which is a ring of smooth bone at the peripheral margin of the endplate, and the central endplate, which is the central portion of the endplate. The epiphyseal rim is relatively solid and strong, as compared to the thin and porous central endplate [ 2 ].

Does the epiphyseal ring vary along the thoracolumbar spine?

The area of the inferior ring was always larger than the superior ring (significant only for lumbar vertebrae), regardless of sex, ethnicity, and age. Conclusion: The epiphyseal ring varies largely in size and shape along the thoracolumbar spine.

What are the superior and inferior surfaces of the vertebral body?

The superior and inferior surfaces of a typical vertebral body are nearly flat or slightly concave and are rough suited for the attachment of fibrocartilaginous discs. The margins of the superior and inferior surfaces are formed from a secondary center for ossification, the epiphyseal ring, and are smooth.

How do you measure the epiphyseal ring?

Measurements of the vertebral body and epiphyseal ring were taken using a digital caliper at four different locations: anterior, posterior, right, left. In addition, each vertebral surface was photographed and the epiphyseal ring area measured (using image analyzer software Image J).
