Skeletal System

Because if your ligaments are injured, bone to bone friction can occur!

Both can be as painful as each other. Even if the rib is broken there is nothing that can be done medically other than wait for it to heal.

It usually takes around 4-6 weeks for a bruised rib to heal, roughly about the same time as a broken one.

no the frontal bone is your forehead the foramen magnum is where your spinal corde goes into your skull. It is located in the occipital bone.

no it does not .. all it does is move your bones a little. and it will not cause arthritis

The smallest are in the ear and the majority of bones are in your feet

There are normally thirty-three (33) vertebrae in humans, including the five that are fused to form the sacrum (the others are separated by intervertebral discs) and the four coccygeal bones that form the tailbone. The upper three regions comprise the remaining 24, and are grouped under the names cervical (7 vertebrae), thoracic (12 vertebrae) and lumbar (5 vertebrae), according to the regions they occupy. This number is sometimes increased by an additional vertebra in one region, or it may be diminished in one region, the deficiency often being supplied by an additional vertebra in another. The number of cervical vertebrae is, however, very rarely increased or diminished.

With the exception of the first and second cervical, the true or movable vertebrae (the upper three regions) present certain common characteristics that are best studied by examining one from the middle of the thoracic region. (source wikipedia)

the bone marrow.

Well, first off, your marrow cavity is where blood is made. Without fresh blood, your immune system would crash, and, in the case of an accident, your body could not restore lost blood. Secondly, a fractured bone is much more painful than a bone with a clean break. If the marrow cavity was gone, then more fractures would occur than breaks would.

A torn meniscus can significantly impair the function of the knee joint by causing pain, swelling, and reduced range of motion. The meniscus acts as a cushion and stabilizer, so its injury can lead to joint instability and increased wear on the cartilage. This may result in difficulty with activities such as walking or bending the knee, and can increase the risk of developing osteoarthritis over time. Additionally, the torn meniscus may cause locking or catching sensations in the knee during movement.

They grow.

No, because your legs would be not controlled and the life would be like a life without legs.

Let me guess... walking on our hands? Well, you wouldn't be able to stand on your hands.

So the only way to move is by pushing yourself on the ground by your hands.

What if you don't have hand muscles?

Well, this isn't the main question.

Thank you.

There is a diagram of the skeletal system at this website ...

A wrist is a part of your elbow that allows for movement.

No. the collar bone is the clavicle. The clavicle is the anterior portion of the shoulder girdle. The scapula is the posterior portion of the shoulder girdle.

They contain and support the lungs, and (along with the sternum, or breastbone) provide additional structural protection for the heart and other organs.

the most, part of the back at risk is the spinal cord

It depends what you are using as a proportion. It is long compared to a single vertebrae but short in comparison to the entire spine.

yes

Marrow, and it doesn't hold blood vessels, it makes them.

The exact number of bones varies with every human, but there is no general difference between the genders.

Lung, liver, stomach, small intestine, heart

Secondary ossification centers appear in the epiphyses.
