What are Vertebrae? Vertebrae are the highly specialized bones which collectively make up the spinal column. The spinal column is such a distinctive anatomical feature that all animals with spinal columns are known as vertebrates, referencing the vertebrae. In humans, 33 separate bones make up the spinal column, and the structure begins to form around the third week of gestation.

vertebra Any of the bones that make up the vertebral column. Each vertebra contains an arched, hollow section through which the spinal cord passes. In humans, the vertebrae are divided into cervical, thoracic, and lumbar sections, and the sacrum and coccyx are both made up of a series of fused vertebrae.

vertebrate A vertebrate is an animal that has a backbone and a skeleton. Vertebrate animals include humans. When you think about vertebrates, think about bones: this word has to do with animals that have a lot of bones, in the form of a skeleton. It especially refers to animals with a backbone, which protects their spinal cord. Vertebrates have many bones, including a skull which protects their brains, which tend to be large.

- 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 animal.ach of the vertebrae is an irregular bone. The size of the vertebrae varies according to placement in the vertebral column, spinal loading, posture and pathology. Along the length of the spine the vertebrae change to accommodate different needs related to stress and mobility.

- Most vertebrates have a spinal column made of bones called vertebrae (see SPINE). But some, such as the shark, do not have a bony spinal column. Sharks have vertebrae made of cartilage.Vertebrates are classified in the phylum chordata and make up the subphylum vertebrata.hose bones are called vertebrae so the animals are vertebrates. The animals that do not have backbones are called invertebrates. Some examples of vertebrates include human beings, cats, dogs, fish, elephants, and chickens.

L2 L2. The L2 vertebra is the second lumbar spinal vertebra in the human body. Along with the other vertebrae, it makes up the spinal column, which supports the upper half of the human body. The lumbar vertebrae are the largest movable bones of the backbone.he L2 vertebra is located in the lower curvature of the spine, and the portion of the spinal cord that it protects is known as the lumbar cord.

Seventh cervical vertebra Cervical vertebrae. In vertebrates, cervical vertebrae (singular: vertebra) are the vertebrae of the neck, immediately below the skull. Thoracic vertebrae in all mammalian species are those vertebrae that also carry a pair of ribs, and lie caudal to the cervical vertebrae. Further caudally follow the lumbar vertebrae, which also belong to the trunk, but do not carry ribs.

Vertebral column Vertebral column of a goat. The vertebral column, also known as the backbone or spine, is a bony skeletal structure found in vertebrates. It is formed from individual bones called vertebrae (singular: vertebra), which houses the spinal canal, a cavity that encloses and protects the spinal cord.There about 50,000 species of animals that have a vertebral column.ertebrae are defined by the regions of the vertebral column that they occur in. Cervical vertebrae are those in the neck area. With the exception of the two sloth genera (Choloepus and Bradypus) and the manatee genus, (Trichechus), all mammals have seven cervical vertebrae.

- 10 most extreme places on Earth. The spine, alternately known as the vertebral column or backbone, is the structure that encloses and protects the spinal cord, which is the bundle of nerves that transmits signals from the brain to the rest of the body. The human spine serves to protect the bundle of nerves known as the spinal cord. 2  The spine is a central and crucial connector within the human skeletal structure.
