For example, the most superior cervical vertebrae is termed C1 and the most inferior C7, which is then followed by the
T1 vertebrae
of the thoracic region. The cervical region of the spine is the most superior and contains seven small vertebrae.
What is the most superior bone of the vertebral column?
The cervical vertebrae
are the smallest and most superior of the vertebrae. The most superior of these vertebrae articulate with the skull. The thoracic vertebrae are matched to each pair of ribs to form the rib cage and establish the thoracic cavity.
What is the thoracic region of the vertebral column?
The thoracic spine is
the longest region of the spine
, and by some measures it is also the most complex. Connecting with the cervical spine above and the lumbar spine below, the thoracic spine runs from the base of the neck down to the abdomen. It is the only spinal region attached to the rib cage.
What are the 5 regions of the vertebral column from superior to inferior?
- 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 is the thoracic region of the spine?
Thoracic (mid back) – the main function of the thoracic spine
is to hold the rib cage and protect the heart and lungs
. The twelve thoracic vertebrae are numbered T1 to T12. The range of motion in the thoracic spine is limited. Lumbar (low back) – the main function of the lumbar spine is to bear the weight of the body.
Which vertebra has an Odontoid process?
The odontoid process (also dens or odontoid peg) is a protuberance (process or projection) of
the Axis (second cervical vertebra)
. It exhibits a slight constriction or neck, where it joins the main body of the vertebra.
Which bone is most superior?
Anatomical terms of bone
In anatomy,
the atlas (C1)
is the most superior (first) cervical vertebra of the spine and is located in the neck. It is named for Atlas of Greek mythology because, just as Atlas supported the globe, it supports the entire head.
How is thoracic back pain treated?
Because pain in the thoracic region is often caused by muscle tension and poor posture, initial treatment efforts focus on relieving the tension with stretching, massage, and
over-the-counter medications such as acetaminophen or ibuprofen
. Heat and/or ice therapy can help reduce muscle pain and stiffness as well.
What are the symptoms of thoracic spine nerve damage?
- Significant leg weakness or loss of sensation.
- Loss of feeling in genitals or rectal region.
- No control of urine or stool.
- Fever and lower back pain.
- A fall or injury that caused the pain.
Which region of the human body is the thoracic vertebrae located?
Upper Back
. The spine in the upper back and abdomen is known as the thoracic spine. It is one of the three major sections of the spinal column. The thoracic spine sits between the cervical spine in the neck and the lumbar spine in the lower back.
Which two bones are not connected by a suture?
Sutures of the Skull:
The bones of the skull, with one pair of exceptions, are joined together by immovable fibrous joints called sutures. (See Fig. 6-7 and 6-8.) The exceptions are the jaw joints, the movable synovial joints between the mandible and the
2 temporal bones
.
What does the first vertebra pivots around?
| Question Answer | The first vertebra is called Atlas | When the head is moved from side to side, the first vertebra pivots around the Axis of the second vertebra | What vertebrae have the largest and strongest bodies? Thoracic | The number of vertebrae that fuse to form the sacrum is Five[] |

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 does thoracic nerve pain feel like?
Individuals with a thoracic pinched nerve often experience some of the following symptoms:
Pain in the middle of the back
.
Pain that radiates to the front of the chest or shoulder
.
Numbness or tingling
that extends from the back into the upper chest.
What parts of the body does the thoracic spine control?
The thoracic spine has 12 nerve roots (T1 to T12) on each side of the spine that branch from the spinal cord and control motor and sensory signals mostly for
the upper back, chest, and abdomen
.
Where is the lower thoracic region?
The section of the spinal column called the thoracic spine begins
below the cervical spine (C7, neck)
, roughly at shoulder level and continues downward until it reaches the first level of the low back (L1, lumbar spine). Twelve vertebrae, numbered T1 through T12 from top to bottom, make up the thoracic spine.
