What is Columna Vertebralis?
The series of vertebrae that extend from the cranium to the coccyx, providing support and forming a flexible bony case for the spinal cord. Synonym(s): columna vertebralis [TA] , backbone, rachis, spina, spinal column, spine (2) . VERTEBRAL COLUMN.
What is the transverse process of the vertebrae?
Transverse process is a small bony projection off the right and left side of each vertebrae. The two transverse processes of each vertebrae function as the site of attachment for muscles and ligaments of the spine as well as the point of articulation of the ribs (in the thoracic spine).
What are the 4 functions of the vertebral column?
The vertebral column provides attachments to muscles, supports the trunk, protects the spinal cord and nerve roots and serves as a site for haemopoiesis.
What are atypical vertebrae?
Atypical vertebrae are the vertebrae with modified structures due to their function and position. Out of the seven cervical vertebrae, C1 (atlas), C2 (axis) and C7 (vertebra prominens) are atypical vertebrae.
What is the strongest bone in the vertebral column?
Terms in this set (50) The thoracic vertebrae are the largest and the strongest of the unfused bones in the vertebral column.
What are the 5 types of vertebrae?
As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx.
What does the transverse process do?
The transverse process serves as a point of attachment for muscles that help move the vertebrae as well as ligaments that stabilize the vertebral column. Each area has characteristic shapes for this structure.
What are 3 functions of the vertebral column?
The three main functions of the spine are to:
- Protect the spinal cord, nerve roots and several of the body’s internal organs.
- Provide structural support and balance to maintain an upright posture.
- Enable flexible motion.
Why it is called vertebral column?
vertebral column, also called spinal column, spine, or backbone, in vertebrate animals, the flexible column extending from neck to tail, made of a series of bones, the vertebrae.
What are the four atypical vertebrae?
Of the cervical vertebrae, the atlas (C1), axis (C2) and vertebra prominens (C7) are considered atypical cervical vertebrae. The atlas (C1) lacks a body or spinous process.
How many atypical lumbar vertebrae are there?
Of the twelve thoracic vertebrae, five are said to be atypical.
How many bones are there in the vertebral column?
The vertebral column is a series of approximately 33 bones called vertebrae, which are separated by intervertebral discs. The column can be divided into five different regions, with each region characterised by a different vertebral structure.
Where is the vertebral column located?
The vertebral column, also known as the spinal column, is a flexible column that encloses the spinal cord and also supports the head. It consists of various groups of vertebrae and is divided into five different areas. An internal disk is located between each vertebra.
What is the function of the vertebral column?
The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for the body and attachment for the pectoral and pelvic girdles and many muscles. In humans an additional function is to transmit body weight in walking and standing. human vertebral column Human vertebral column. Encyclopædia Britannica, Inc.
What is L5 vertebral body?
The L5 is the lowest with the lumbar region, as it is the closest to the sacrum and the pelvis. Like other lumbar vertebrae, the L5 primarily protects the spinal column. This is the case for most individuals; however, there have been some anatomical variations that have been discovered.
