Sections Of The Spine

The ribs attach to the spine on the thoracic vertebrae.
Sections of the spine. Anatomy of the backbone cervical spine. The vertebral column also known as the backbone or spine is part of the axial skeleton the vertebral column is the defining characteristic of a vertebrate in which the notochord a flexible rod of uniform composition found in all chordates has been replaced by a segmented series of bone. The top two bones are known as the atlas and axis and are different from the others to allow rotation of the skull as well as forwards and backward.
Each section is made up of individual bones called vertebrae. Lumbar spine lower back typically including 5 vertebrae known as l1 to l5 which have a great deal of motion and flexibility. Many of the nerves of the peripheral nervous system or pns branch out from the spinal cord and travel to various.
The cervical the thoracic and the lumbar spine. The vertebral column houses the spinal canal a cavity that. Structure of the spine.
Cervical spine makes up the neck and has 7 vertebrae. A healthy spine has strong muscles and bones flexible joints ligaments and tendons and sensitive nerves. Thoracic spine there are 12 vertebrae t1 to t12 in the chest section called the thoracic spine.
Stacked up like a tower of lego the spinal column is made of 33 bones called vertebrae and is divided into five sections or regions. The first spinal curve is located at the cervical spine. The spinal cord is the neurological pathway for sending and receiving signals to and from the brain.
Because this section of the spine bears most of the body s weight and allows for the most motion which stresses the anatomical structures this is the area associated with most back problems. The normal anatomy of the spine is usually described by dividing up the spine into three major sections. The spinal cord begins at the base of the brain and extends into the pelvis.
