What bone is also known as the knee cap?
The patella (/pəˈtɛlə/), also known as the kneecap or kneepan, is a thick, circular-triangular bone which articulates with the femur (thigh bone) and covers and protects the anterior articular surface of the knee joint. The patella is found in many tetrapods, such as mice, cats, and birds, but not in whales or most reptiles and amphibianssuch as snakes or frogs.

Can you have extra bones in hands?
There are 26 bones in the human foot. Some people have "extra bones" (accessory ossicles) which are usually congenital (present at birth) but may also be due to previous trauma. These extra bones, which can occur with any bone in the foot, can be painless (asymptomatic) and are only noticed when the foot is x-rayed. Sometimes they are painful and cause significant discomfort. This pain can usually be treated by the foot and ankle surgeon using a variety of non-surgical measures, although sometimes the extra bones may need to be surgically removed.

Yes, despite their elastic movement in water, seals have a skeleton. Higher-level organisms generally have skeletons.
What happens to joe ribs when he exhales?
when exhalation takes place, then-
1.there are downward and inward movements of ribs with the contraction of internal intercostal muscles i.e.the muscles which connect with externally. diaphragm also returns to its dome structure , with the relaxation of its radial and circular muscles.
What skeleton does a fly have?
they don't have a skeleton like we do, they are invertabrates meaning they don'thave a back bone. they have an exoskeleton that is like a shell on the out side of their body.

one muscle to contract and the other muscle to retract

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.
