Are all vertebrae the same size?

Purpose of the Vertebrae

Although vertebrae range in size; cervical the smallest, lumbar the largest, vertebral bodies are the weight bearing structures of the spinal column.

Why do vertebrae have different shapes?

The size and shape of each lumbar vertebra is designed to carry most of the body's weight. Each structural element of a lumbar vertebra is bigger, wider and broader than similar components in the cervical and thoracic regions.

What do all vertebrae have in common?

A typical vertebra consists of a body and a vertebral arch. The arch is formed by the paired pedicles and paired laminae. Arising from the vertebral arch are the transverse, spinous, superior articular, and inferior articular processes. The vertebral foramen provides for passage of the spinal cord.

What are the different types of vertebrae based on location describe each?

The vertebral column is formed of four different types of vertebrae: the cervical vertebrae, the thoracic vertebrae, the lumbar vertebrae, and the sacrococcygeal vertebrae, in order from head to hip. The skeleton is what supports and anchors the soft tissue of our body, such as muscles and skin.

Do all vertebrates have the same number of vertebrae?

Copy the link

Nearly all mammals have the same number of cervical vertebrae no matter how long or short their necks are – humans, giraffes, mice, whales, and platypuses all have exactly seven cervical vertebrae.

Are backbone and spine the same thing?

The backbone encloses the spinal cord and the fluid surrounding the spinal cord. Also called spinal column, spine, and vertebral column.

Is vertebral column and spinal cord same?

The vertebral column, also known as the spinal column, is the central axis of the skeleton in all vertebrates. The vertebral column provides attachments to muscles, supports the trunk, protects the spinal cord and nerve roots and serves as a site for haemopoiesis.

How do vertebrae articulate with each other?

Each vertebra has a facet on each side of the vertebral body, which articulates with the head of a rib. There is also a facet on each of the transverse processes which articulates with the tubercle of a rib. The number of thoracic vertebrae varies considerably across the species.

What are the 3 types of vertebrae and how are they different?

The vertebral column can be divided into three segments: Cervical. ... Each of the three segments of the spine has a curve. The cervical spine and the lumbar curve both are convex anteriorly, while the thoracic spine curves the opposite way, convex posteriorly.

What is the shape of the vertebral body?

The vertebral body

It is generally cylindrical in shape, but there is a wide range of variation for the shape and size in different regions and in different mammalian species. The most extreme is the first cervical vertebra (atlas) which has no body.

How many of each vertebrae are there?

Ligaments. The ligaments are strong fibrous bands that hold the vertebrae together, stabilize the spine, and protect the discs. The three major ligaments of the spine are the ligamentum flavum, anterior longitudinal ligament (ALL), and posterior longitudinal ligament (PLL) (Fig. 7).

How many vertebrae does the spine have?

The average person is born with 33 individual bones (the vertebrae) that interact and connect with each other through flexible joints called facets. By the time a person becomes an adult most have only 24 vertebrae because some vertebrae at the bottom end of the spine fuse together during normal growth and development.

What 3 features do all vertebrae have?

The vertebrae are divided into three regions: cervical C1–C7 vertebrae, thoracic T1–T12 vertebrae, and lumbar L1–L5 vertebrae. The vertebral column is curved, with two primary curvatures (thoracic and sacrococcygeal curves) and two secondary curvatures (cervical and lumbar curves).
