Skeletal System
The skeletal system provides definite shape and mechanical support to the body, and it also helps in movement and locomotion. Ask questions about the skeletal system and bones here.

Are children's bones not as strong as adult bones are?
No, they are more pliable when you are younger; when you're older they're more brittle. However children often engage in riskier behavior (climbing, jumping fro unsafe heights, etc.) resulting in falls and similar accidents. This causes more frequent bone breaks.
How are vertebrae attached to each other?
Vertebrae are attached to each other primarily through intervertebral discs and facet joints. The intervertebral discs, which consist of a gel-like nucleus pulposus surrounded by a tough annulus fibrosus, provide cushioning and allow for movement between the vertebrae. Facet joints, located at the back of the vertebrae, connect the bony projections of adjacent vertebrae, enabling stability and facilitating spinal motion. Ligaments, such as the anterior and posterior longitudinal ligaments, also play a crucial role in maintaining the alignment and integrity of the vertebral column.
The reason the pelvic bones, or the hip bones, of a four legged animal are less massive than those of a human is because in humans all of their weight is concentrated onto that one area of the body, and only onto two legs. But in four legged animals there are four legs to distribute the weight onto, thus the hip bone does not need to be as strong.
Tendons are the elastic bands that connect muscle to bone, while ligaments are the bands that connect bone to bone. Both are made of connective tissue that is composed of collagen.
Not really.
A tail needs bones, muscles, and nerves to control it. A human just don't have the parts to build something like that from.
Even if by some amazing medical development it'd be possible to transplant a tail from a dog(which today isn't), there wouldn't be any nerves to hook it up to to make it wag.
You'd have to take the nerves intended for some other muscles and use those instead, but then you'd lose the use of those muscles.

What is the rate of complications following a lumbar laminectomy?
After laminectomy (postoperative), there is a risk of developing complications that can include blood clots, infection, excessive bleeding, worsening of back pain, nerve damage, or spinal fluid leak
What is located at the end of each long bone?
The spongy bone is the type of bone that you will find at the expansion of longer bones. This helps to fill the irregular spots in bones to make them complete.
What measures can reduce the risk of fractures?
Adequate calcium intake is necessary for strong bones and can help decrease the risk of fractures. People whodonot getenough calcium in their diets can take a calcium supplement. Exercise can help strengthen bones by increasing bone density
What two primary hormones that effect bones?
Parathyroid which:
"breaks down" bones to increase blood calcium levels
What is the triangular bone in your chest called?
There is a Xiphoid process, but I am not sure because you must clearly define your question.
Why is fluid important between bones?
Synovial fluid is important between the bones because it helps reduce the friction between the bones. This fluid also lets a person move his joints more freely.
They don't have bone because they're an invertebrate. They have an exoskeleton instead.
No. They have a rigid outer layer called an exoskeleton
What bones articulate to form a saddle joint?
The trapezium (a carpal bone) and the first metacarpal (that goes to the thumb) form the only two saddle joints in the human body.
What the adaptations of the thoracic vertebra?
have long spinous process which is directed downward. transverse process and centrum serve as points of attachment for ribs
Myelodysplasias (myelodsplastic syndrome) are bone marrow disorders that impact blood cell production.
Where are genes located in the human body?
Genes are in every cell in the body, in the nucleus. They are the genetic material.
it is well hidden in the nucleas it embedds itself in to it
