Skeletal System

Osteocytes

The patella is part of the knee, therefor it is part of the skeletal system.

i don't know how long, but i can tell you that my horse bowed his tendon racing, and we only found out last month that it caused scar tissue in his shoulder from leaning on his other leg so much. it hardly effects him, but sometimes he imagines that he's done it again, he's not too confident on that side.

yes your ribs can pierce your organs. a common example would be in a car crash. no seat belt and your ribs crack and your lungs and organs and whatever are thrown into the cracked lung piercing the organ!

The four main layers of bones are the periosteum (outer layer), compact bone (dense and hard layer), spongy bone (porous inner layer), and bone marrow (innermost layer responsible for blood cell production).

At the time of birth a child has 300 bones but these bones fuse with each other as the child grows up and at adulthood the figure drops to 206.

The Tibular Bone Is A Bone in your Knee!

Each rib is a separate bone. 12 bones on the left and 12 on the right that gives a total of 24 bones.

The 11th and the 12th ribs are called floating ribs as the have no connection on the front with the sternum.

Dendritic spines are micron-sized protuberances of neuronal membrane that receive and initially process most of the excitatory signals transmitted in the brain. Since first described by the great neuroanatomist, Santiago Ramon y Cajal, over a century ago, dendritic spines have been a popular source of conjecture in the field of neuroscience. Many hypotheses have been offered to explain their function, from increasing the surface area available for synaptic contacts, to controlling the intracellular diffusion of signaling molecules, to providing a means for neurons to connect with their neighbors in the densely-packed environment of the brain. Perhaps the best-supported of these hypotheses is that dendritic spines enable learning and memory through the discrete, local management of synaptic input. Each dendritic spine contains a special complement of proteins which not only transduce synaptic signals, but which adapt to signal activity and determine synaptic efficacy. These adaptations can affect the expression or function of neurotransmitter receptors, the localization of signaling proteins within the dendritic spine, even the dendritic spine size and shape. In turn, these changes can affect the sensitivity of the dendritic spine to subsequent synaptic signals and so are believed to be an important means of recording memories in the brain.

Cold weather can affect the skeletal system by causing joints to stiffen and muscles to tighten, which can increase the risk of injury. Prolonged exposure to cold temperatures can also reduce blood flow to bones, potentially leading to decreased bone density and increased risk of fractures. Adequate warmth and proper physical activity are important for maintaining skeletal health in cold conditions.

The patella moves as the knee joint flexes and extends, gliding up and down in the trochlear groove of the femur. It is held in place by the quadriceps muscle and its tendon, which provide stability during movement. The patella also functions to increase the leverage of the quadriceps muscle, allowing for more efficient movement.

Trochanter. A large, rough projection.

Is it only on the left side? Does it seem to travel to your back as well? Do you drink excessive amounts of alcohol? If you answered no, yes, and yes, it could be pancreatitis, or inflammation of the pancreas, and you should seek medical treatment immediately. The only cure is to discontinue ingestion of anything until the swelling and irritation subsides. But in order to receive vital fluids, you will need to be treated intravaneously (IV) with liquids, vitamins and medications, and the best place for that is the hospital. Length of hospital stay varies with severity of problem, age, overall physical condition, etc. Pancreatitis is extremely painful and eating or drinking anything at all only irritates the organ. It is important to stay hydrated, however, and this explains the need for the IV. Pain medication is administered as the pancreas become less irritated over time, but time is really the only cure. Pain on the left side under the rib can also be signs of a swelling spleen, which requires medical attention.

The tibia bone is found in the lower leg, making up the inner and larger of the two bones in the shin. It is located next to the fibula and is an important weight-bearing bone that helps support the body's structure when standing or walking.

Osteons are a characteristic of compact bone tissue in the skeletal system. They consist of concentric rings of bone matrix called lamellae surrounding a central canal that contains blood vessels and nerves. Osteons provide structural support and help in the transportation of nutrients and waste in bone tissue.

Yes, a tumor on the spine can be dangerous as it may compress the spinal cord or nerves, leading to symptoms such as pain, weakness, or paralysis. Treatment options depend on the type of tumor, its location, and extent of spinal cord compression. Close monitoring and prompt medical intervention are crucial in managing spinal tumors.

A REA (reamer-irrigator-aspirator) device is a surgical tool used in bone graft harvest for a fractured femur. It is designed to remove bone marrow and create a cavity in the bone for graft placement while simultaneously irrigating and aspirating to reduce the risk of thermal necrosis and contamination with bone debris or fat. The REA device helps in harvesting bone graft without the need for a separate irrigation/aspiration system.

The backbone isn't made up of one bone; it's comprised of several small bones called vertebrae.

And adult human has 206 bones in their body. For sake of argument - we'll compute in adult standards: As of May 2009 there are: 6, 634, 236, 512 people on Earth. So, 6634236512 x 206 = *drum roll please* 1, 366, 652, 721, 472 human bones in living individuals on the Earth. (One trillion, 366 billion, 652 million, 721 thousand, 472) This does not include dead and buried bones or animal bones.

You have sesamoidtitis. caused when their is to much pounding or pressure on the ball of your foot. I had this problem two and it got so bad it fractured the sesimoid bone. the bone is a tiny little bone in the ball of your foot, their are 2 of the same bone one on the outside and one on the inside, you should know which bone is injured by where most of the pain comes from (the outer or inner part of the ball on of your foot). their are different ways to approach the situation by either having a boot to rest your foot for a few weeks. crutches are your choice. if you really want to rest it u can have your doctor put a cast on it. also you can get a coutarzon shot to eaz the pain. last if this doesn't go away after numerous times, rest and treatment their is also the option of removing the sesimoid.

i believe that i have a twisted collar bone. quite a good physio diagnosed this. it occured when i was trying out snowboarding (i should have stuck to skiing) and came down heavy on the shoulder. i thought i had really damaged it at the time but as i got up, everything worked.

a few monnths later i noticed some 'clicking' sounds as i moved the shoulder. eventually i saw the physio who measured all the angles and done a grip strength test showing the affected side was a lot weaker - transmitting all the way down to the biceps and forearms.

as usual with physio i didnt do any of the exercises but really should. i might try swimming to build the muscle up again and get good movement. i still have to lean against a wall with my arm raised (ala Lethal Weapon) to force the collar bone back and i feel it pop back into place.
