What are the 5 vertebral columns?
Vertebrae. As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx.
Where are the 5 different sections of the vertebral column located?
The spine is composed of 33 bones, called vertebrae, divided into five sections: the cervical, thoracic, and lumbar spine sections, and the sacrum and coccyx bones. The cervical section of the spine is made up of the top seven vertebrae in the spine, C1 to C7, and is connected to the base of the skull.
What region has 5 vertebrae?
lumbar spine
The upper back, or thoracic spine, has 12 vertebrae, labeled T1-T12. The lower back, or lumbar spine has five vertebrae, labeled L1-L5. The sacrum and coccyx (tailbone) are made up of nine vertebrae that are fused together to form a solid bone. The sacrum is labeled S1.
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).
What are the 5 lumbar vertebrae?
Position of human lumbar vertebrae (shown in red). It consists of 5 bones, from the top down, L1, L2, L3, L4 and L5. The lumbar vertebrae are, in human anatomy, the five vertebrae between the rib cage and the pelvis.
How many vertebral columns are there?
In humans, the vertebral column usually consists of 33 vertebrae, placed in series and connected by ligaments and intervertebral discs. However, the number of vertebrae can vary between 32 and 35. Usually there are 7 cervical, 12 thoracic, 5 lumbar, 5 sacral and 4 caudal (coccygeal) 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)
Which region of the vertebral column is under the cervical region?
Beneath the last cervical vertebra are the 12 vertebrae of the Thoracic Spine. These are abbreviated T1 through T12 (top to bottom). T1 is the smallest and T12 is the largest thoracic vertebra.
What are the vertebral region?
The vertebrae of the spinal column are divided into five regions: cervical, thoracic, lumbar, sacral, and coccyx.
How do you remember the 5 regions of the vertebral column?
You can use a meal-related mnemonic to remember them – imagine a crunchy breakfast at 7 am (7 cervical vertebrae), a tasty lunch at 12 noon (12 thoracic vertebrae), and a light dinner at 5 pm (5 lumbar vertebrae).
What are the regions of the vertebral column in descending order?
The adult vertebral column consists of 24 vertebrae, plus the sacrum and coccyx. The vertebrae are divided into three regions: cervical C1–C7 vertebrae, thoracic T1–T12 vertebrae, and lumbar L1–L5 vertebrae.
Where is vertebrae 4 and 5?
The L4 and L5 are the two lowest vertebrae of the lumbar spine. Together with the intervertebral disc, joints, nerves, and soft tissues, the L4-L5 spinal motion segment provides a variety of functions, including supporting the upper body and allowing trunk motion in multiple directions.
