Vertebrae: The spine has 33 stacked vertebrae (small bones) that form the spinal canal. The spinal canal is a tunnel that houses the spinal cord and nerves, protecting them from injury. Most vertebrae move to allow for a range of motion. The lowest vertebrae (sacrum and coccyx) are fused together and don’t move.
Is vertebrae another word for spine?
In this page you can discover 4 synonyms, antonyms, idiomatic expressions, and related words for vertebrae, like: spinal-column, spine, chine and backbone.
What is the vertebral column?
(ver-TEE-brul KAH-lum) The bones, muscles, tendons, and other tissues that reach from the base of the skull to the tailbone. The vertebral column encloses the spinal cord and the fluid surrounding the spinal cord. Also called backbone, spinal column, and spine.
What is the difference between vertebrae and vertebral column?
The vertebral column is the bony segmented structure that protects the spinal cord and supports the thorax and head. One segment of the vertebral column is known as the vertebra (plural vertebrae). Based on the location of the vertebrae, their names differ as cervical, thoracic, lumbar, sacral and coccyx.What bones are part of the spinal column?
The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
What is another name of vertebrates?
vertebrate, also called Craniata, any animal of the subphylum Vertebrata, the predominant subphylum of the phylum Chordata. They have backbones, from which they derive their name.
What is the scientific name for spine?
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.
Is spinal cord and vertebral column the same?
The vertebral column surrounds the spinal cord which travels within the spinal canal, formed from a central hole within each vertebra. The spinal cord is part of the central nervous system that supplies nerves and receives information from the peripheral nervous system within the body.What is another name for spinal cord?

Article first time published onWhat is the difference between notochord and vertebral column?
The key difference between notochord and vertebral column is that notochord is a flexible rod-like structure that supports the nervous tissue in lower chordates, while the vertebral column is a structure containing 33 vertebrae, running from the skull up to the pelvis in vertebrate higher chordate animals.
Does the vertebral column protect the spinal cord?
The spinal cord is protected by bones, discs, ligaments, and muscles. The spine is made of 33 bones called vertebrae. The spinal cord passes through a hole in the center (called the spinal canal) of each vertebra. Between the vertebrae there are discs that act as cushions, or shock absorbers for the spine.
How many vertebral column are there?
Vertebrae. 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).
Is the vertebral column part of the axial skeleton?
These are (1) the axial, comprising the vertebral column—the spine—and much of the skull, and (2) the appendicular, to which the pelvic (hip) and pectoral (shoulder) girdles and the bones and cartilages of the limbs belong.
What type of bone is a vertebrae?
Irregular Bones They are primarily spongy bone that is covered with a thin layer of compact bone. The vertebrae and some of the bones in the skull are irregular bones.
Which part of the skull is connected with the vertebral column?
The atlas is the topmost vertebra and, with the axis (the vertebra below it), forms the joint connecting the skull and spine. The atlas and axis are specialized to allow a greater range of motion than normal vertebrae. They are responsible for the nodding and rotation movements of the head.
What are the 4 parts of the spine?
Typically, the spine is divided into four main regions: cervical, thoracic, lumbar and sacral.
Where is C1 on the spine?
The C1 and C2 vertebrae are the first two vertebrae at the top of the cervical spine. Together they form the atlantoaxial joint, which is a pivot joint. The C1 sits atop and rotates around C2 below.
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.
What is the opposite word of vertebrates?
invertebrate Add to list Share. An invertebrate is an animal without a backbone. … Your backbone allows you to stand up straight, and it also allows you to be grouped with the other vertebrates: animals with backbones. Invertebrates are the opposite: they have no backbone. These are the two major groups of animals.

What is vertebrate antonym?

What is another name for spinal column?
Also called vertebral column.
Where is the vertebral foramen?
In a typical vertebra, the vertebral foramen is the foramen (opening) formed by the anterior segment (the body), and the posterior part, the vertebral arch. The vertebral foramen begins at cervical vertebra #1 (C1 or atlas) and continues inferior to lumbar vertebra #5 (L5).
How do you remember spinal cord syndrome?
- Motor > sensory.
- Upper limb involved > lower limb.
- Distal involved > proximal.
Why is the vertebral column longer than the spinal cord?
Because the spinal cord is considerably shorter than the vertebral column (see Figure 1.10A), lumbar and sacral nerves run for some distance in the vertebral canal before emerging, thus forming a collection of nerve roots known as the cauda equina.
Is a notochord a spine?
A notochord does not become the spine, but rather fills the spaces between vertebrae in some animals.
What is difference between nerve cord and notochord?
Notochord is a skeletal rod, and nerve cord is a solid strand of nervous tissue. The main difference between notochord and nerve cord is that notochord belongs to the skeleton whereas nerve cord belongs to the central nervous system of chordates. … Nerve cord occurs below the notochord.
What is difference between vertebrates and invertebrates?
Vertebrates have a skeletal structure with a spinal column or backbone. Invertebrates have no backbone, while vertebrates have a well-developed internal skeleton of cartilage and bone and a highly developed brain that is enclosed by a skull.
Which body organ is protected by the spinal column?
Bones also protect the body’s organs. The skull protects the brain and forms the shape of the face. The spinal cord, a pathway for messages between the brain and the body, is protected by the backbone, or spinal column.
How do the vertebrae protect the spinal cord where do spinal nerves exit the vertebral column?
The vertebral foramen provides for passage of the spinal cord. Each spinal nerve exits through an intervertebral foramen, located between adjacent vertebrae. Intervertebral discs unite the bodies of adjacent vertebrae.
