What are the 5 regions of the spinal cord?

What are the 5 regions of the spinal cord?

As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx. Did you know? Only the top 24 bones are moveable. The vertebrae of the sacrum and coccyx are fused.

What are the three regions of the spinal cord?

The upper three regions of the spinal column are termed the cervical, thoracic, and lumbar; they contain individually jointed vertebrae. The two lower regions—the sacrum and coccyx, or tailbone—are formed from fused vertebrae.

What are the different parts of the spinal cord?

The spinal cord comprises three parts: the cervical (neck), thoracic (chest), and lumbar (lower back) regions. Three layers of tissue protect the spinal cord: the dura mater, arachnoid mater, and pia mater.

What are the two regions of the spinal cord?

The spinal cord is about 18 inches (45 centimeters) in length and is relatively cylindrical in shape. The cervical (neck) and lumbar (lower back) segments house the spinal cord’s two areas of enlargement. A fibrous band called the filum terminale begins at the tip of the conus medullaris and extends to the pelvis.

What are the five regions of the spine quizlet?

The five major regions of the vertebral column are the cervical region, thoracic region, lumbar region, sacrum, and coccyx.

What are the 4 spinal areas?

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

What are the different parts and functions of the spinal cord?

What does the spinal cord do?

  • Motor Functions – directs your body’s voluntary muscle movements.
  • Sensory Functions – monitors sensation of touch, pressure, temperature and pain.
  • Autonomic Functions – regulates digestion, urination, body temperature, heart rate, and dilation/contraction of blood vessels (blood pressure).

What are the 3 main parts of a vertebra?

The normal anatomy of the spine is usually described by dividing up the spine into three major sections: the cervical, the thoracic, and the lumbar spine. (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.

What are the 5 regions of the vertebral column from superior to inferior?

From superior to inferior, these are:

  • Cervical: 7 vertebrae (C1 = highest; C7 = lowest)
  • Thoracic: 12 vertebrae (T1 = highest; T12 = lowest)
  • Lumbar: 5 vertebrae (L1 = highest; L5 = lowest)
  • Sacral: 5 fused vertebrae (S1 = highest; S5 = lowest)
  • Coccygeal: 3-4 fused vertebrae (Co1 = highest; Co3 = lowest)

What are the 5 regions of the vertebral column how many bones are in each region?

Answer: The adult vertebral column consists of 24 vertebrae, plus the sacrum and coccyx. The vertebrae are subdivided into cervical, thoracic, and lumbar regions. There are seven cervical vertebrae (C1–C7), 12 thoracic vertebrae (T1–T12), and five lumbar vertebrae (L1–L5).
