The spine (or backbone) runs from the base of the skull to the pelvis. It serves as a pillar to support the body's weight and to protect the spinal cord.
The major function of the vertebral column is protection of the spinal cord; it also provides stiffening for thebody and attachment for the pectoral and pelvic girdles and many muscles. In humans an additional function is to transmit body weight in walking and standing.
Vertebral column in general. The vertebral column usually consists of 33 vertebrae: 24 presacral vertebrae (7 cervical, 12 thoracic, and 5 lumbar) followed by the sacrum (5 fused sacral vertebrae) and the coccyx (4 frequently fused coccygeal vertebrae).
Spinal Cord & Column. The spinal column, more commonly called the backbone, is made up primarily of vertebrae, discs, and the spinal cord. Acting as a communication conduit for the brain, signals are transmitted and received through the spinal cord.
- The femur (/ˈfiːm?r/, pl.
- The femur is the only bone in the upper leg.
- In the condition genu valgum (knock knee) the femurs converge so much that the knees touch one another.
- The femur is the longest and, by some measures, the strongest bone in the human body.
No, you can not live without a spinal column. It is made up of many vertebrae, which are special types of bones, arranged in a column, so it can also be referred as a vertebral column.
The spine is made up of 33 interlocking bones called vertebrae (pronounced vur-tuh-bray) . You can think of vertebrae like beads on a string, able to bend, twist, and turn. Vertebrae make up the spine. From the skull all the way down to the tailbone, the vertebrae sit on top of one another in a slight s-shape.
Your backbone, or spine, is actually made up of a stacked column of 33 separate bones called vertebrae, each of which has a hole in it, through which the spinal cord runs.
The lumbar spine (lower back) is a remarkably complex structure. The L4-L5 are the two lowest vertebrae in the lumbar spine, and together with the attached disc, joints, nerves and soft tissues, it provides a variety of functions, including supporting the upper body and allowing motion in multiple directions.
Vertebral and disc pain from L5-S1 may occur suddenly following an injury or gradually develop over a period of time. Typically, a dull ache or sharp pain may be felt in the lower back. Discogenic pain is typically worsened by prolonged sitting, standing in one place, and repetitive lifting and bending activities.
Taking non-steroidal anti-inflammatory drugs (NSAIDs) for relief. Receiving cortisone injections directly into the spinal column to provide short-term relief. Engaging in exercise and physical therapy that focuses on strengthening the back and abdominal muscles as well as stretching.
Spine. The spine, also known as the vertebral column or spinal column, is a column of 26 bones in an adult body — 24 separate vertebrae interspaced with cartilage, and then additionally the sacrum and coccyx.
The thoracic vertebrae are situated between the cervical (neck) vertebrae and the lumbar vertebrae. These thoracic vertebrae provide attachment for the ribs and make up part of the back of the thorax or chest. Damage or SCI's above the T1 vertebra affects the arms and the legs.
The spinal cord (and brain) are protected by three layers of tissue or membranes called meninges, that surround the canal . The dura mater is the outermost layer, and it forms a tough protective coating. Between the dura mater and the surrounding bone of the vertebrae is a space called the epidural space.
Common causes of low back pain (lumbar backache) include lumbar strain, nerve irritation, lumbar radiculopathy, bony encroachment, and conditions of the bone and joints. Lumbar strain is considered one of the most common causes of low back pain. The injury can occur because of overuse, improper use, or trauma.
Keep Active
- Exercise at least 30 mins, 3 times a week.
- Take rest breaks every hour: recline in your chair for a moment or walk around for a few minutes.
- Change your position. If seated, stand up; if standing, walk around.
- Perform a different task every hour or so & use different muscles to relieve back.
The second thoracic vertebra, or T2, is located directly below the first thoracic vertebra (T1). It is slightly larger than the T1, but smaller than the third thoracic vertebrae (T3). The second thoracic vertebra contains faceted sides that allow the vertebra to press up against the ribs.
In between your vertebrae, you have intervertebral discs (also labeled on the above image). These act like pads or shock absorbers for your spine as it moves. Each disc is made up of a tire-like outer band called the annulus fibrosus and a gel-like inner substance called the nucleus pulposus.
The spine, or backbone, is made up of a column of 33 bones and tissue going from the skull to the pelvis. These bones, or vertebrae, enclose and protect a cylinder of nerve tissues known as the spinal cord.
Treatment
- Rest. One to 2 days of bed rest will usually help relieve back and leg pain.
- Nonsteroidal anti-inflammatory medications (NSAIDs). Medications such as ibuprofen or naproxen can help relieve pain.
- Physical therapy.
- Epidural steroid injection.
Areas the Nerves Control. The nerves in the area of a vertebra control specific parts of the body. For example, the 7th cervical nerve (C7) in the neck area controls the triceps (the muscle in the upper arm), while the thoracic nerves (T2 through T7) control the chest muscles.
The lumbar spine – the lower back, composed of five vertebrae, provides support for the majority of your body's weight. The thoracic spine – the middle back, made up of the 12 vertebrae in between the cervical and lumbar spine.
The main parts of the spine include:
- Vertebrae.
- Intervertebral discs.
- Spinal cord and nerves.
- Muscles.
- Facet joints.
- Ligaments and tendons.
If you say that someone has no backbone, you think that they do not have the courage to do things which need to be done. You might be taking drastic measures and you've got to have the backbone to do that.
