Why do your wrists and ankles click?
It can be simply a tendon or ligament that is very slightly off position and clicks back into position as it puts itself back into place with movement. It can also be a sign of tendinitis if there is repetitive motion of those joints or other chronic stresses that could cause the tendon to become inflamed (like in "tennis elbow") . This can also occur if you have arthritis in those joints since there is often too little synovial fluid and perhaps too much wear on the joint cartilage (or even down to the bone) from the disease process that rubs and clicks when moved. If there is pain associated or weakness, numbness or other concerning symptoms, you should get an exam from a health care professional.
How long before dental sutures fall out?
What happens if you crack your knee?
If you break your kneecap, you will be in immediate pain, and probably won't be able to walk. If this happens, you need to go to a hospital asap and get an xray. If it really is broken,,,it is quite possible that you will need surgery, not always, but quite often that happens. In either case, you will be put in either an immobilizer or a cast for several weeks. When you're allowed to take whichever you have off,,,you will hardly be able to bend your leg and will probably be sent for physical therapy. You will discover that your muscles are really weak after all the time of not using them much. Trust me, breaking your kneecap is NOT what you want to do,,it is a very , very long road back to any sort of normalcy. Remember, the gangsters who offered to "break your kneecap" didn't do that because it was an easy recovery. Most people who break their kneecap, measure their life before their injury , and after their injury.
What happens in the epiphyseal face?
The cartilage cells at the epiphyseal side are continuing to grow and divide mitotiacally and the diaphyseal side are aging and dying and the osteoblast move in to form bone.
So they are growing on the ends side and in the middle side of the Epiphyseal line they are dying and form bone.
What is the medical term meaning procedure to stabilize a fractured bone?
Setting the bone is called "reduction" in medical terms.

Distal Clavicle Resection
Overview
Reviewed by Dr. Ken Alleyne
The tip of the shoulder blade (scapula) that forms the roof of the shoulder joint is known as the acromion. Where this bone meets the collarbone (clavicle) is known as the acromioclavicular (or AC) joint. Normally, the tendons of the shoulder and the fluid-filled sac that surrounds it, the bursa, have plenty of room underneath the AC joint. However, overuse of the shoulder may lead to bursitis and tendonitis, collectively known as impingement. Impingement causes the tissues underneath the AC joint to be pinched against the bone, causing irritation and pain. Additionally, arthritis can develop in the shoulder as a result of overuse (Arthrosis) or autoimmune attack (Rheumatoid Arthritis). Physical therapy, medication, or cortisone injections are most often prescribed for shoulder pain; however, if these methods fail to provide relief, arthroscopic surgery may be necessary.
Removing the end of the clavicle closest to the acromion may help alleviate some pain and loss of motion caused by arthritis or impingement. Removing the last third of the clavicle allows it to be replaced by more flexible scar tissue, thereby eliminating the bone-on-bone rubbing that causes pain. The procedure often is accompanied by a bone spur removal, Debridement, or other procedures. A distal clavicle resection is one of the newer additions to shoulder arthroscopy.

Procedure
Before the Procedure:
The patient's medical history and any possible allergies to medication are determined. The surgeon may order X Rays, an MRI, CT Scan, or EMG to look into the joint before the procedure. The patient is dressed in a hospital gown and anesthetized either locally or generally.
During the procedure:
A number of half-inch incisions will be made to allow the arthroscope to enter the shoulder joint. A sterile saline solution will be pumped into the joint both to cleanse it and to expand it for better visualization. The surgical staff may also pump air into the joint to create more room to see inside the joint. While watching a monitor that shows a magnified image of the inside of the shoulder, the surgeon guides the arthroscope to perform a number of procedures within the joint.
After removing any degenerative or damaged tissue around the AC joint and bursa (see Debridement) bone spurs from the acromion, or repairing the rotator cuff, the surgeon uses a surgical cutter to remove the last half-inch from the clavicle. The surgeon may then move the arm to test for impingement. The patient may be discharged following the procedure, or may remain in the hospital for one or two days.
The class of bone based on its shape that the patella is a good example of are sesamoid bones. The patella is also known as the kneecap.
The cartilage that provides support for the larynx and external ear?
elastic cartilage supports the external ear
What is the main function of the ear bones?
As far as I can tell the ear lobe serves no real function as far as from a medical standpoint. I have known several people with no ear lobes & they function just fine in all ways. About the only things they are good for is appearance, they may make the ear look more or less attractive depending how they are shaped. The other is to hang things on them, either clipped on or through a hole or holes made in them, for ornamental purposes as many do.
How bones help the body maintain homeostasis?
homoeostasis of the bone calcium is via parathyroid hormone (PTH). PTH controls the amount of vitamin the production and therefore how much calcium is absorbed in gut. PTH also controls the balance between calcium in the blood and the bone.
If you did not have bones, then you wouldnâ??t be able to walk upright. You would really just move around a bit like a blob.
What would happen without a urinary system?
Without the digestive system, we wouldn't even be able to move! To get energy for everyday things, you need to eat and use the digestive system to get nutrients to your cells. Then, you can cartwheel, wash dishes, ride your bike, or anything else!
Is the hardest bone to break the tailbone?
You can break it by falling on a hard surface like the ground. I once fell off a moving golf cart and I thought i either cracked, broke, or bruised my tailbone. I still haven't seen a doctor about it but i suggest you don't try breaking your tailbone, it hurts, a lot!
How many bones make up the skeleton of the arm?
If you count the arm as strictly the arm (upper arm), it is only one, the humerus.
If you are counting loosely and counting the lower arm too, it would be 3, the humerus, the radius, and the ulna.
Does blood formation happen in red or yellow bone marrow?
During later period of prenatal haemopoesis and in during postnatal haemopoesis the blood is formed in red bone marrow.
Yellow bone marrow has the ability to reactive itself and become red bone marrow when needed.
What is the pain in my lower left side right below the ribs?
I am experiencing a pain in the same location you described and was looking for answers as well, this forum helped point me in the right direction, I think I may have a hiatal hernia, because my pain started after I did stock at work lifting a bunch of 40lb boxes, check this link and see if this fits for your situation http://www.medhelp.org/forums/gastro/messages/36555.html
What do you do if you have a brocken arm?
If someone breaks their arm, take them to a hospital to see a doctor. The doctor should then take care of everything from there and inform the person of everything he/she needs to know to take care of their broken arm.
Get them to a hospital for xrays and treatment. If you are out somewhere rural, then clean any abrasions, strap the arm to a piece of wood to keep it from moving and walk out. Isolating the limb so it cannot move is probably the best immediate help--do not attempt to realign it. Get to a medical facility--preferably a hospital--as soon as possible.
What is the the function of a ligament?
Ligaments are strong, flexible bands (or cords) of dense regular fibrous connective tissue that hold bones firmly together at the joints, but are elastic enough to allow some movement. They help to stabilise joints and support organs, muscles, or other body parts. They prevent extensive movement or movement in the wrong direction. For instance, the ATF ligament (the most commonly sprained ligament in your ankle) that prevents your tibia and talus from separating when you roll your ankle in, or your transverse ligament in your cervical spine that prevents your neck from going too far forward and damaging your spinal cord (and killing you).
What is the largest bone in our body?
The largest bone in the human ankle is the calcanius (heel bone); the densest bone, because it bears the most weight is the talus.
There are three types of ligaments.
- Articular ligaments: Fibrous tissue that connects bones to other bones. They are sometimes called "articular larua, "fibrous ligaments", or "true ligaments".
- Peritoneal ligaments: A fold of peritoneum or other membranes.
- Fetal remnant ligaments: The remnants of a tubular structure from the fetal period of life.
The first term is the one most commonly intended when using the word "ligament". This article briefly handles peritoneal and fetal remnant ligaments before focusing on articular legments
What happens when calcium levels in the blood drop?
"groans (constipation), moans (psychotic noise), bones (bone pain, especially if PTH is elevated), stones (kidney stones), and psychiatric overtones(including depression and confusion)."
What does Having porous bones mean?
While the word porous isn't generally used in medical terminology, -porotic is the medical terminology combining form meaning porous. For instance, osteoporotic means a condition of more porous bones.
