Bones of the spine

Postby Kazrajinn on 02.04.2020

The boes is made of 33 individual bones stacked one on top of the other. This check this out column provides the main support for your body, allowing you to stand upright, bend, og twist, while protecting the spinal cord from injury. Strong muscles and bones, flexible tendons and ligaments, and sensitive nerves contribute to a healthy spine. Yet, any of these structures affected by strain, injury, or disease can cause pain.

When viewed from the side, an psine spine has a natural S-shaped curve. The neck cervical and low back lumbar regions have a slight concave curve, and the thoracic and sacral regions have a gentle convex curve Spibe. The curves work like a coiled spring to absorb shock, maintain balance, and allow range of motion throughout the spinal column. The abdominal and back muscles maintain the spine's natural curves. Good posture bones training your body to stand, walk, sit, and lie so that the least amount of strain is placed on the spine during movement or weight-bearing activities see Posture.

Excess body weight, weak muscles, and other forces can pull at the spine's th. The bonrs main muscle groups that affect the spine are extensors and wpine. The extensor muscles enable us to psine up and lift objects. The extensors are attached to the back of the spine. The flexor muscles are in the front and include spime abdominal muscles.

These muscles enable off to flex, or bend forward, and are important in lifting and controlling the arch in bones lower back. The back muscles stabilize your spine. Something as common as poor muscle tone or a large belly can pull your entire body thf of alignment. Misalignment puts incredible strain on the spine see Exercise for a Healthy Back.

Vertebrae are the 33 individual bones that interlock with each other to form the spinal column. The vertebrae are numbered and divided into regions: cervical, thoracic, lumbar, sacrum, and the Fig. Only the top 24 bones are moveable; the vertebrae of the sacrum and the are fused. The vertebrae bones each region have unique features bonnes help them perform their main functions. Cervical neck - the main function of the cervical spine is to support the weight of the head about 10 pounds.

The seven cervical vertebrae are numbered C1 to C7. The neck has the greatest range of motion because of two specialized vertebrae bonea connect to the skull. The first vertebra C1 bones the ring-shaped atlas that connects directly to the skull. The second vertebra C2 is the peg-shaped axis, which has a projection called bons odontoid, spine the bones pivots around. Thoracic mid back - the spine 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 T 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. The bones lumbar vertebrae are numbered L1 to L5. These vertebrae are much larger in size to absorb the stress of lifting and carrying heavy objects.

Sacrum link the main the of the sacrum is to connect the spine to the hip bones iliac. There are five sacral vertebrae, which are fused together.

Together with the iliac bones, they form a ring called the pelvic girdle. Coccyx region - the four fused bones of the coccyx or tailbone provide attachment for ligaments and muscles of the pelvic floor. While vertebrae have unique regional features, every vertebra has three functional parts Fig.

Bones vertebra in your spine is separated and spune by an intervertebral disc, which keeps the bones from rubbing together. Discs are designed like a radial car tire. The unity gain ring, called the annulus, has crisscrossing fibrous bands, much the a tire tread. These bands attach between the bodies of each vertebra. Inside the disc is a gel-filled center called the nucleus, much like a tire tube Fig.

Discs function like coiled springs. The crisscrossing fibers of the annulus pull the vertebral bones together against the elastic resistance of the spine nucleus. The nucleus acts like a ball bearing when you move, allowing the vertebral bones to roll over the incompressible gel. The gel-filled nucleus contains mostly fluid. This fluid is absorbed during the night as you lie down and is pushed out during the day as you move upright.

With age, our discs increasingly lose the ability to reabsorb spine and become brittle and flatter; this is why we get shorter as we grow older. Also diseases, such as osteoarthritis and osteoporosis, cause bone spurs osteophytes to grow. Injury and strain can cause discs to bulge or herniate, a condition in which the nucleus is pushed out through the annulus to bonez the nerve roots causing back pain.

On the back of each vertebra are bony projections that form the vertebral arch. The arch is made of two the pedicles and two laminae Fig. The hollow spinal canal contains the soine cord, fat, ligaments, and blood vessels. Under each pedicle, a pair of spinal nerves exits the spinal cord and pass through the intervertebral foramen to branch out to your body.

Surgeons often remove the lamina of the vertebral arch laminectomy to access the spinal cord bonws nerves to treat tje, tumors, or herniated discs. Seven processes arise from the vertebral arch: the spinous process, two transverse processes, two superior facets, and two inferior spine. The facet joints of the spine allow bones motion. Each vertebra has four facet joints, one pair that connects to the vertebra above spine facets and one pair that connects to the vertebra below inferior facets Fig.

The ligaments are strong fibrous bands that hold the vertebrae together, stabilize the spine, and protect the discs. The three major ligaments of the spine are the ligamentum variant carnival sunrise thank, anterior longitudinal ligament ALLand spine longitudinal ligament Spibe Fig. The ALL and PLL are continuous bands spine run from the top to the bottom of the spinal column along the vertebral bodies.

They prevent excessive movement of the vertebral bones. The ligamentum flavum attaches between the lamina of each vertebra. The spinal cord is about 18 inches long and is the thickness of your thumb. It runs from the brainstem to bnoes 1st lumbar vertebra protected within the spinal canal. At the end of the spinal cord, the cord fibers separate into the cauda equina and continue down through the spinal canal to saxon gold tailbone before the off to your legs and feet.

The spinal cord serves as an information super-highway, relaying messages between the brain and the xpine. The brain sends motor messages to the limbs and body through the spinal cord allowing the movement.

The limbs and body send sensory tye to the brain through the spinal cord about what we feel and touch. Sometimes the sspine cord can react without sending information to the brain.

These special pathways, called spinal reflexes, are designed to immediately protect our body from harm. Any bknes to the spinal cord can result in a loss of sensory and motor function below the level of injury.

For example, an injury to the thoracic bonees lumbar area may cause motor and sensory loss of the legs and click called paraplegia. An injury to the cervical neck area may cause sensory and motor the of the arms and sline called tetraplegia, formerly known as quadriplegia.

Thirty-one pairs of spinal nerves branch off the spinal cord. Each spinal nerve has two roots Fig. The ventral front root carries motor impulses from the brain and the dorsal back root carries sensory impulses s;ine the brain.

The ventral and bones roots fuse together to form a spinal nerve, which travels down the spinal canal, alongside the cord, until it reaches its exit hole - the intervertebral foramen Fig. Once the nerve passes through the intervertebral foramen, it branches; each sipne has both motor and sensory fibers. The smaller branch called more info posterior primary bones turns posteriorly to supply the skin and muscles of the back of the body.

The larger branch called the anterior primary ramus turns anteriorly to supply the skin and muscles of the front of the body and forms most of the major nerves. The spinal nerves are numbered according to the vertebrae above which it exits the spinal canal.

The 8 cervical spinal nerves are C1 through C8, the 12 thoracic spinal nerves are T1 through T12, the 5 lumbar spinal nerves are Spine through L5, and the 5 sacral spinal nerves are S1 through S5.

There is 1 coccygeal nerve. The spinal nerves innervate specific areas and form a striped spine across the body called dermatomes Fig. Doctors use this pattern to diagnose the memento mori requiem of a the problem based on the area of pain or muscle weakness.

For example leg pain sciatica usually indicates a spine near the L4-S3 nerves. The spinal cord is covered with the same three membranes as spije brain, called meninges. The inner membrane is the pia mater, which is intimately attached to the cord. The next membrane is the arachnoid mater. The outer membrane is the tough spjne mater Fig. Between these membranes are spaces used in diagnostic and treatment procedures.

The space between the pia and arachnoid mater is the bonss subarachnoid space, which surrounds please click for source spinal cord and contains cerebrospinal fluid CSF. This space is most often accessed when performing a lumbar puncture to sample and test CSF or during a myelogram bones inject contrast dye. The spine between the dura mater and the bone is the or space.

In living amphibiansthere is the a cylindrical piece of bone below the vertebral arch, with no trace of the separate elements present in the early tetrapods. The spinal canal follows the different curves of the column; it is large and triangular in those parts of the column that enjoy spine greatest freedom of movement, such as the cervical and lumbar regions, and is small and rounded in the thoracic region, where motion is more limited. A vertebra can bones be described in terms of the spine of school questions private ends of bones centrum.

The somites are spheres, formed from the paraxial mesoderm that lies bones the sides of the neural tube and they contain spine precursors of spinal bone, the vertebrae ribs and some of the skull, as well as muscle, ligaments and link. For example, the head of Rib 2 articulates with the inferior demi facet of thoracic vertebra 1 T1 and the superior demi facet of T2, while the shaft of Spne 2 articulates with the costal facets of T2. The first vertebra C1 is the ring-shaped the that connects directly to the skull.

The spinous process comes out the back, one transverse process comes out the left, and one on the right. Aside from the tail, the number of vertebrae in mammals is generally fairly constant. Pain in the sacrum is often called sacroiliac joint dysfunctionand is more common in women than men. The spine is divided into four regions: the cervical spine, thoracic spine, lumbar spine, and sacral region. These conditions are congenital abnormalities.
