What are the 5 vertebral groups?
The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig.
Who are vertebrae?
Vertebrae are the 33 individual, interlocking bones that form the spinal column. Each vertebra has three main functional components: the vertebral body for load-bearing, the vertebral arch to protect the spinal cord, and transverse processes for ligament attachment.
What are the 12 vertebrae?
The T9, T10, T11, and T12 vertebrae form the base of the thoracic spine. The thoracic spine is made up of 12 segments total between the cervical and lumbar levels. The spinal cord and nerves’ correlation to these levels, along with the rest of the thoracic spine, aid in controlling the trunk of the body.
What are the 26 vertebrae?
The spine, also known as the vertebral column or spinal column, is a column of 26 bones in an adult body — 24 separate vertebrae interspaced with cartilage, and then additionally the sacrum and coccyx.
What happens if you break a vertebrae?
If the entire vertebral column breaks, it results in a burst fracture. If the compression is mild, you will experience only mild pain and minimal deformity. If the compression is severe, affecting the spinal cord or nerve roots, you will experience severe pain and a hunched forward deformity (kyphosis).
Is your neck connected to your spine?
The neck is connected to the upper back through a series of seven vertebral segments. The cervical spine has 7 stacked bones called vertebrae, labeled C1 through C7. The top of the cervical spine connects to the skull, and the bottom connects to the upper back at about shoulder level.
Why do we have 26 vertebrae?
The spine is made up of 33 vertebrae. More than 13 million neurons are found in the spine. Adults only have 26 vertebrae because bones fuse together as we age.
What do all vertebrates have in common?
These phyla can be classified into two groups (vertebrates or invertebrates) based on external and internal physical characteristics.
What are vertebrae numbers?
Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused.
What is the vertebrae bone?
Anatomical terms of bone. [edit on Wikidata] In the vertebrate spinal column, each vertebra is an irregular bone with a complex structure composed of bone and some hyaline cartilage, the proportions of which vary according to the segment of the backbone and the species of vertebrate.
