What is spinal cord Class 10?

The spinal cord is a part of the central nervous system. It is a long pipe-like structure arising from the medulla oblongata, part of the brain consisting of a collection of nerve fibres, running through the vertebral column of the backbone.

Where is T12 in your back?

The T12 vertebra sits right above the lumbar spinal column. It is the largest and most inferior of the thoracic spinal vertebrae. The T12 vertebrae location is between the T11 vertebra and the first lumbar vertebra, L1, in the trunk region.

What are the small bones that make backbone known as?

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.

What is spinal cord and backbone?

Spinal Cord is the tube-like structure which consists of bundles of nerve fibers. It is covered by the meninges and is surrounded by the cerebrospinal fluid. Backbone or the spinal column is the central axis of the skeleton in all vertebrates. In a newborn human, there are about 33 bones that make up the spinal column.

How many S vertebrae are there?

(Below the lumbar spine is a bone called the sacrum, which is part of the pelvis). Each section is made up of individual bones, called vertebrae. There are 7 cervical vertebrae, 12 thoracic vertebrae, and 5 lumbar vertebrae. An individual vertebra is made up of several parts.

What are the names of the vertebrae?

The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2).

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.
