Why do our bones in arms and legs are tube like structure?
They aren't, or at least not like you seem to think.
The bones in arms and legs (along with most large-ish bones, ie pelvis) contain marrow. Red bone marrow is found at the ends of the bone and is involved in a number of blood regulating functions, and yellow 'fatty' marrow is in the middle of the bones.
Where can you find the tarsals bones?
The tarsals are superior to the meta-tarsals in the lower part of the ankle.
The true hyaline cartilage is the knee's intra-articular cartilage found in the joint surface. It has collagen but does not possess nerves or blood vessels.
Why is the skull thick and strong?
The skull is very thick because of your brain. The brain is one of the most important internal organs, am I not correct? It controls your breathing, heart beat, and your ability to think. The brain is very well protected by the skull. People who have cracked their skull open tend to have brain damage due to not having enough bone to cover and protect the brain.
Why are human bones so strong?
First, they're a compound material (like fiber-glass) where the solid is a rock (calcium appetite) and the gell is collogen.
Also- look at a good x-ray of a long bone- all those arches and struts are designed (by time & experiance, yours) to give maximum strength for the least weight.
(the trick is two sets of cells - one is always desolving your bones, and the second builds up every micro break)
For weight bone is one of the strongest materials on earth, super light, flexible and strong, they are chambers of hollow walls allowing them to bend. Most people think bone is weaker than concrete because people break bones on it, but if you were to compare a piece of concrete to the exact same size as bone it would break easily. Bone is 40 times more stress resistant than concrete. Steel is 10 times stronger than bone, but is 4.5 times heavier. Bone is good with compression, a femur can hold about 1-2 tones of weight with compression strengths, but is weaker with torsion (bending) and tensile loads (stretching). Bone is made from calcium and phosphorus. To keep bones healthy and strong; dairy products is needed in a person's diet. How bones maintains its strength and flexibility is that every 7 years a bone replaces all of its cells, this makes bones adapt to day to day events such as running. Running increases the body's mass by three times, and a jump puts bones up to ten times the body's mass. Example; Currently I am an 14 year old and I weigh about 57kg. When I decide to jump; The force of jumping and landing increases my weight up to aproximately 570kg or half a ton; jumping from a roof may break my bone as this increases the force much higher which would make me weigh as much as 800 kg but since I have shock absorbers in my knees this prevent's my bones from breaking. Shock aborbers play an important role when jumping from an high height. Tendons in the knee can withstand a tonne before breaking. Cartilage absorbs pressure, it can hold about 7 tonnes before breaking! So when I jump up and down this prevents me from breaking my bones. Human's bones are well built indeed.
You must be at least 18 years of age and no older than 60. An individual must be 18 to donate because marrow donation is a surgical procedure and the person undergoing the procedure must legally be able to give informed consent. A guardian or parent cannot sign a release or give consent because unrelated marrow donation is a voluntary procedure and is not beneficial or life-saving to the donor.
What is a bone found in the backbone?
The backbone is a column usually consisting of 24 vertebrae, the sacrum, intervertebral discs, and the coccyx situated in the dorsal aspect of the torso, separated by spinal discs.
What part of the skeleton affords most complete protection of the body?
it is the skull that affords most complete protection of the body it protects the brain or some how i not sure maybe the ribs and spinal cord is the one who affords but in my study the ribs protects the lungs and the spinal cord is connected to the nervous stem BUT I'AM NOT SURE SORRY
What is tissue which connect muscle t bone?
Tendons connect muscles to bones. It is important not to confuse tendons with ligaments which connect two bones together.
In your body, the most bones you have are located on your feet!
Hope that helps you !
Give you 5 specific things to keep the muscular system healthy?
The muscular system requires significant attention to work at optimum conditions. Regular activity coupled with adequate sleep and a healthy balanced diet should keep all systems in great operating order.
What is the difference Between Fish bones and human bones?
a fish bone is more brittle
I THINK!!!!!!!
Is the patella distal to the tibia?
The more commonly known kneecap sits on the top (anterior) side of our tibia (shinbone), the largest and weight-bearing bone of the lower leg.
