What is a tough rubbery tissue that makes up parts of the skeleton?
Cartilage (pronounced: KAR-tul-ij), a flexible, rubbery substance in our joints, supports bones and protects them where they rub against each other.
What substance keeps the bone hard and tough?
Made mostly of collagen, bone is living, growing tissue. Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.
What is the hard but flexible tissue between most bones called?
Cartilage is an important structural component of the body. It is a firm tissue but is softer and much more flexible than bone. Cartilage is a connective tissue found in many areas of the body including: Joints between bones e.g. the elbows, knees and ankles.
How do the mobile vertebrae articulate with each other?
The mobile vertebrae articulate with each other via joints between their bodies and articular facets: Left and right superior articular facets articulate with the vertebra above. Left and right inferior articular facets articulate with the vertebra below.
What is the jelly-like substance inside the spine?
Inside this protective covering is a jelly-like substance known as mucoprotein gel. This interior is known as the nucleus pulposus. As the spine receives pressure, the gel moves inside the annulus fibrosus and redistributes itself to absorb the impact of the pressure.
What connects the articular surface of the vertebral column to the disc?
The articular surfaces are covered by hyaline cartilage, and are connected by the intervertebral disc. Two ligaments strengthen the vertebral body joints: the anterior and posterior longitudinal ligaments, which run the full length of the vertebral column.
What connect the vertebral body to the transverse process?
In the thoracic vertebrae, the transverse processes articulate with the ribs. Pedicles – connect the vertebral body to the transverse processes. Lamina – connect the transverse and spinous processes. Articular processes – form joints between one vertebrae and its superior and inferior counterparts.
