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.

Bone responds to pressures. A person can look at a skeleton and tell if that person is left or right handed. The skeleton began even but the pressure or influences by using it makes it thicker. It lays down more bone using osteoblasts (bone+Builders). When a bone is broken, the osteoblasts form a bridge which is very thick. When it is mended, the osteoclast (bone+breaker) break down the extra bone to form the original (or close to the original) shape. This double process is also called bone remodeling.
What are fingers and toes for?
Toes came about because they were useful to the early mammals to dig shelter burrows, grip the ground when running (Sort of like a tractor tread), and to have a number of nails to help in the above. Later ... much later, the short mammalian toes grew longer and more flexible as a result of changes, like standing up when walking. Longer toes were very helpful in balancing while erect.
At some point, for a certain small group of mammals that we call primates, it was useful for the toes to have the most inner toe wrap around opposite the other toes so that it was easier to grip a branch, and perhaps swing from tree to tree. This quickly led to longer, more efficient toes. At this point, you could say that this small group of specialized species of mammal had hands all around. As walking and running standing up became the standard way of getting around, these new subhumans had what we call "hands" up top, and feet down below, for walking.
This led to an explosion of new skills for the species because of this ability to grip things with an opposable thumb. It is from these small but extremely useful changes that intelligence grew in leaps and bounds, leading to larger brains, which led to more skills, until today, this changing species can send text on a telephone with just one of those opposable toes, which are now known as fingers.
On the lighter side:
We have fingers and toes to count or we can use a calculator in math class or in science class when we divide or multiply numbers.
What happens when there is not enough cartilage to pad joints?
This does happen to many people and they suffer a lot of pain. The bones then rub against each other every time the joint is moved.
How are the skeletal system the muscular system and the nervous system connected to each other?
Skeletal system provides the support and shape to the body. It works as a base that muscles attach to using tendons. Muscles contract and relax in order to move the body.
Why do ribs have names like truefalse and floating?
True ribs, because 7-pairs of costal cartilages join 7-pairs of ribs DIRECTLY to the sternum.
False ribs, because the costal cartilage join 3-pairs of ribs to the seventh-rib not the sternum.
Floating ribs, because the last 2-pairs of ribs neither connects to a costal cartilage and the sternum.
Why aren't the ears or the nose on the skull?
Because the skull is made of bone/calcium while the ears and nose are made of cartilage. It takes longer for bones to degrade and turn into dust. With the nose and ears, there are no bones involved so degradation occurs in a more rapid timeline.
If you must actually open the skull, typically pilot holes are drilled and a bone saw is used to connect the holes, creating a plug of skull that can be replaced post-surgery. Note this this is not a common procedure at all, and the neurosuregeon will usually use an existing opening in the skull rather than creating a new one., if possible.
What is the purpose of the big phalanges?
Big phalanges and others they're all in your fingers and toes and they help you stay balanced and that's why you're able to grasp things with you fingers and toes... Hope I Helped!:)
What is the flat bones of the face?
They are...
Frontal Bone: Above eyes.
Parietal Bones (2): Behind frontal bone. One on the left, one right.
Occipital Bone: Back of the head.
Temporal Bones (2): Joins pare ital bones near base.
Sphenoid Bone: Between the temporal, parietal, front, and the facial bone zygomatic. (goes through to both sides)
Ethmoid Bone: In front of the sphenoid bone.
Why yes of course! The human body can do amazing things, with a doctors help of course. You see when you have a minor break or fracture the doctor will most likely put a cast on it to keep it in place while your body gets to work on mending the bone. If the bone completly breaks in half then the doctor would most like put a few clips on the bone to help the bone find it way to the other half.
Hope this helps!:)
Which portion of a long bone is located nearest the midline?
The xyphoid process that is the terminal end of the sternum, should be pretty close
What is the individual bones of the skull called?
There are many different bones in the human body. An adult body consists of 206 bones.
What is the lateral end of the clavicle?
The lateral end of the clavicle is the one closest to the arm and farthest from the breastbone. It articulates with the acromion process of the scapula.
What system protects the inner organs?
The integumentary system (skin and its glands) is the primary protection the body has against pathogens and physical injury and essentially keeps things from falling out. Additionally, certain parts of the skeletal system provide vital protection for certain organs of the body:
- the cranial bones protect the brain
- the ribcage protect the heart and lungs
- the vertebral column protects the spinal cord
How does the ciculatory system relate to the skeletal system?
The heart is enclosed in the thorax. That is in the rib cage. The thoracic and abdominal aorta is protected by the spine. You have one arm and thigh bone and one artery for each one. You have two forearm bones and two leg bones and two arteries. Only the common carotid arteries are not protected. Rather could not be protected. The carnivorous animals grab the front of the neck by instinct only. The arm and thigh arteries are placed medially to get the protection.
What is the scientific name for the the jaw bones?
The UPPER Jaw bone is called the Maxilla. This bone does not move and is part of the skull. The upper teeth are found in this bone.
The LOWER Jaw bone is called the Mandible. This bone does move. The lower teeth are found in this bone.
What is the difference between giraffe bones and human bones?
Girraffe bones are obviously bigger and taller than ours, ecspecially the spine.
