What are the 4 major curves of the vertebrae?
There are four natural curves in the spinal column. The cervical, thoracic, lumbar, and sacral curvature.
Which region of the vertebral column is immediately superior to the lumbar region?
Which region of the vertebral column is immediately inferior to the lumbar region? The sacrum is located below the lumbar region, articulating superiorly with L5 and inferiorly with the coccyx. The shape of the spinous process can be used to help determine if a vertebra is from the lumbar region.
Which region of the vertebral column is most flexible?
cervical spine
The most flexible part is the cervical spine (neck area). The bones that make up the spine also protect the spinal cord, which runs through the spinal canal.
How many regions of the vertebral column are there?
The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and coccyx (Fig. 2). Only the top 24 bones are moveable; the vertebrae of the sacrum and coccyx are fused. The vertebrae in each region have unique features that help them perform their main functions.
Which of the 4 curvatures of the vertebral column are not present at birth?
The curves correspond with each group of vertebrae, and are: the cervical curve, the thoracic curve, the lumbar curve and the pelvic curve (formed by the sacrum and coccyx). The cervical curve (not present at birth) forms around the time an infant is 3 months old.
What are the 5 regions of the vertebral column?
As mentioned above, our vertebrae are numbered and divided into five regions: cervical, thoracic, lumbar, sacrum, and coccyx.
Which region of the vertebral column is located superior to the thoracic region and which region is inferior to the thoracic region respectively quizlet?
Superiorly: cervical and inferiorly: lumbar. The cervical region of the vertebral column is located above the thoracic region, and the lumbar region is found immediately below the thoracic region.
How many spinal regions are there?
Anatomically, the spine is divided into four regions: The top seven vertebrae that form the neck are called the cervical spine and are labeled C1-C7. The upper back, or thoracic spine, has 12 vertebrae, labeled T1-T12. The lower back, or lumbar spine has five vertebrae, labeled L1-L5.
What are 5 regions of the spine?
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 four regions of the spine quizlet?
Terms in this set (4)
- Sacral. Base of spine. Primarily gray matter (simple reflex).
- Lumbar. Lower back. Entry and exit port of extensive motor and sensory innervations from lower limbs.
- Thoracic. Mid back area.
- Cervical. Neck area.
Which curves of the vertebral column are present at birth?
Both the thoracic curve and the pelvic curve are present at birth. The curves in the spine allow the human body to stand upright, and to maintain balance.
