What are the region of the spine?
The spine (also called backbone or vertebral column) starts at the top of your neck, just under the scull, and goes all the way down to your tail-bone. There are 5 regions of the spine: cervical, thoracic, lumbar, sacral, and coccygeal. However the 3 most commonly discussed regions are the cervical, thoracic, lumbar regions. The cervical region is in the neck. The thoracic region is in the upper to mid back. The lumbar region is in the low back. The sacral region is in the back of your pelvis, between your buttocks. Finally, the coccygeal region is your "tail-bone."
What type of cartilage is found between vertebral bone?
The 12 thoracic vertebrae compose the middle segment of the vertebral column, between the cervical vertebrae and the lumbar vertebrae. They are intermediate in size between those of the cervical and lumbar regions; they increase in size as one proceeds down the spine, the upper vertebrae being much smaller than those in the lower part of the region. They are distinguished by the presence of facets on the sides of the bodies for articulation with the heads of the ribs, and facets on the transverse processes of all, except the eleventh and twelfth, for articulation with the tubercles of the ribs.
Exactly what it sounds like. A hip bone is taken out, through surgery of course, and then is replaced with a prostetic. My mom's 'new' hip is made of titanium.

A bone conserving alternative to a Total Hip Replacement (THR) is hip resurfacing. The Birmingham Hip Resurfacing (BHR) is a bone conserving implant aimed at young active patients who want there quality of life back!
Instead of replacing the old worn out joint, a BHR resurfaces the femoral head with a Cobalt-Chrome component and inserts a Cobalt-Chrome cup into the acetabular socket. This metal on metal technique last longer and has less wear than the traditional Metal on Plastic THR.
By conserving the bone at the femoral head, revisions should they be needed are much simplier than they are if a THR has been carried out at first.
The BHR was pioneered by Derek McMinn in Birmingham, UK. The implant has a high success rate currently at 97% at 13 years which compared to similar statistics for a THR, the difference is staggering. See McMinn Centre website for more details!
How long is recovery from distal clavical resection?
I had an AC decompression (distal clavicle resection) on 12/12/08. It is now 3/3/09 and I am about 80% better.
My pain before the surgery was quite bad and I had been favoring the arm for a long time so my recovery may be longer than some people. Also, I am 47 years old, so younger people might recover better.
I have been doing physical therapy twice a week since the surgery. I now have full range of motion and feel fine most of the time. I still have some minor pain when trying to use my arm over my head.

What occurs when a ligament is stretched too far?
Somtimes, if you are lucky, you just fracture your leg. But in most cases, you'll die almost as soon as it happens, you should be very cafeful? Are you a survivor? My sister wasn't.
Why is calcium removed from the bones?
Calcium is banked in the bones, so when the body needs calcium, a special cell can break down part of the bone and release some of the calcium into the blood to supply to the body.
What is a nerve block on the spine?
A form of anesthesia where medication is administered into the spinal fluid to lessen labor pain or provide anesthesia for a Cesarean delivery.

What is the name of grating sounds when broken bones move together?
Crepitation also known as crepitus is the sound heard when the ends of a broken bone move together.
What parts of the body are most vulnerable?
neck, eyes, spine, groin, and for some laughs throw in some joint locks to pop bones out of their sockets or to break bones at joints like elbows, fingers, knees, ect...
Why do you put casts on broken bones?
The inside of a cast is coated with a high tech, bio engineered "paste" that is absorbed by the skin. Upon absorption, the skin cells become hard and, over time, seal the broken bones. In short, the skin is essentially turned into a type of fully functional, synthetic bone.
When were Napiers Bones invented?
Who Invented And What They Are!!!!!!!! Napier's bones is an abacus created by John Napier for calculation of products and quotients of numbers that was based on Arab mathematics and lattice multiplication used by Fibonacci writing in the Liber Abaci. Also called Rabdology (from Greek word) . Napier published his version of rods in a work printed in Edinburgh, Scotland, at the end of 1617 entitled Rabdologiæ. Using the multiplication tables embedded in the rods, multiplication can be reduced to addition operations and division to subtractions. More advanced use of the rods can even extract square roots. The abacus consists of a board with a rim; the user places Napier's rods in the rim to conduct multiplication or division. The board's left edge is divided into 9 squares, holding the numbers 1 to 9. The Napier's rods consist of strips of wood, metal or heavy cardboard. Napier's bones are three dimensional, square in cross section, with four different rods engraved on each one. A set of such bones might be enclosed in a convenient carrying case. A rod's surface comprises 9 squares, and each square, except for the top one, comprises two halves divided by a diagonal line. The first square of each rod holds a single-digit, and the other squares hold this number's double, triple, quadruple and so on until the last square contains nine times the number in the top square. The digits of each product are written one to each side of the diagonal; numbers less than 10 occupy the lower triangle, with a zero in the top half. A set consists of 9 rods corresponding to digits 1 to 9. The figure additionally shows the rod 0; although for obvious reasons it is not necessary for calculations.
What instruments did the Incas use when doing a skull surgery?
well you see first they would have straped the patient down to try and restrain them then they would insert a drill type mecanism and simply drill into the skull
What is the bone between the knee and the hip?
As it appears like a single bone there,,actually its nt kinda dat... Der r two bones.. Tibia and Fibula ... Stronger 1 is Tibia nd weaker one is Fibula.
Which is the name for a broken bone?
A broken bone is often called a "fracture" or "bone fracture". Some examples from the Wikipedia entry on bone fracture.
* Complete Fracture- A fracture in which bone fragments separate completely. * Incomplete Fracture- A fracture in which the bone fragments are still partially joined. * Linear Fracture- A fracture that is parallel to the bone's long axis. * Transverse Fracture- A fracture that is at a right angle to the bone's long axis. * Oblique Fracture- A fracture that is diagonal to a bone's long axis. * Compression Fracture-A fracture that usually occurs in the vertebrae. * Spiral Fracture- A fracture where at least one part of the bone has been twisted. * Comminuted Fracture- A fracture causing many fragments. * Compacted Fracture- A fracture caused when bone fragments are driven into each other * Open Fracture- A fracture when the bone reaches the skin * Bug fracture- A fracture when the bone is in place, but the fracture has the appearance of a crushed insect.
Why does bone tissue heal quickly?
It is easier for the bones of children to heal faster than adults because their bones are still in the process of growing. Up to about 18-19 years of age, the bone-forming cells (osteoblasts) are more abundant in both number and activity, than is seen on older adults. Starting as young as age 30, the body may begin to decline in its ability to maintain bone density and healing. Cells within the body are constantly working to remove broken down bone particles, and replacing them with new ones. As an individual ages, this process slows down, resulting in a longer healing time for adults.
In children their bones are made of red bone marrow which produces blood. Blood helps bones regenerate. After a certain period, their bones are filled with yellow bone marrow (which produces fat). Therefore the regeneration process slows down. XD
Which exercise can make your legs long?
Squats Well, squats are a good place to start but if you're going for a well rounded fitness and appearance it's a little more involved. There are several exercises, besides squats, that will help achieve this goal including calf raises, dead lift, one-legged squats, power cleans and some stationary flexion and extension machine exercises. The key is combining all of the above, mixing it up to keep your body from adapting to specific exercises, and working at higher weights and lower repetitions. Remember, this is for building muscle mass in particular.
