The human spine consists of 33 individual vertebrae, categorized into five regions: cervical (7 vertebrae), thoracic (12 vertebrae), lumbar (5 vertebrae), sacral (5 fused vertebrae), and coccygeal (4 fused vertebrae). Each pair of vertebrae in the cervical, thoracic, and lumbar regions is separated by intervertebral discs that provide cushioning and allow for movement. The sacral vertebrae are fused to form the sacrum, while the coccygeal vertebrae form the coccyx, or tailbone. Together, these vertebrae protect the spinal cord and support the body's structure.
Yes. There are twelve thoracic vertebrae and a pair of ribs associated with each of them.
The individual units of the backbone are called vertebrae.
Thoracic vertebrae are attached to a pair of ribs
Each individual bone in your back is a vertebra (plural vertebrae).
Between each pair of vertebrae, you can find an intervertebral disc which acts as a shock absorber and provides cushioning for the spine. The disc consists of a tough outer layer called the annulus fibrosus and a soft inner core known as the nucleus pulposus.
A pair of spectacles has an individual lense, one for each eye.
Each thoracic vertebrae is associated with a pair of ribs; therefore, there are 12 pairs of ribs around the chest cavity.
Vertebrae
The individual bones of the spine are called vertebrae. There are 33 vertebrae in total, categorized into five regions: cervical (neck), thoracic (upper back), lumbar (lower back), sacral (pelvis), and coccygeal (tailbone).
Individual vertebrae make up the spinal cord.
Genes come in pairs, with one inherited from each parent. These pairs of genes work together to determine an individual's traits, such as eye color or height. The specific combination of genes in each pair influences how traits are expressed in an individual.
When you get wire that is a shielded pair, you get two individual conductors that are each individually insulated from each other, and the pair is twisted and wrapped with a thin layer of foil to provide electromagnetic shielding to the pair. Occationally you'll see the pair is surrounded with a braided shield, but not commonly. That's your shielded pair.
