Skeletal System

50000000

Depends what type of bones you're talking about. Some are found at archeological sites, (such as prehistoric, or dinosaur bones), and others are found inside your body or the bodies of other living things.

Articular cartilage, also called hyaline cartilage, is the smooth, glistening white tissue that covers the surface of all the freely moveable joints, such as the knee and shoulder, in the human body.

The depression on the surface of a bone is called a fossa. It is a shallow, basin-like structure that typically serves as an attachment site for muscles or tendons.

No, there is no bone in your tongue. The tongue is a muscle, and only a muscle.

use a hot and could pattern. right after the injury apply a bandage and lay a ice pack over the injured area for about 20 min @ a time do that 4 about 2 days then start adding heat apply ice 4 about 20mins then heat 4 about 20 mins do this 4 a few days and while u are in school or out to keep it in a bandage or some kind of brace but wile you are not doing anything keep it elevated above heat level resting on a pillow way to tell if a wrist is sprained would be swelling lake of movement and other things like brusing but u dont always need to have theses sytoms 4 it to be sprained.

hope this helped

You would have all your organs semi-exposed and unprotected, you could not move, you could not do anything with your hands, you would not have teeth, you could not open your mouth a.s.o. You wouldn't be able to function!

Yes. The definition of an organ is: a structure that contains at least two different types of tissue functioning together for a common purpose. The skeletal system contains organs such as bones, cartilage, ligaments and tendons which are all used to facilitate mobility and for the overall structural support of the body.

Joints occur where two bones meet. They make the skeleton flexible - without them, movement would be impossible.

Both are mammals. So the skeletons are almost same. This may be insulting statements for many of you but then it is true. There is difference of the size and shape but then the bones are same. In case of the horse the bones are quite strong and bigger. In case of horse you have single toe evolved as a hoof. You can find very small four bone there in rudimentary state. Your elbow is rotated by 90 degree. Tell bones are rudimentary in man as compared to horse.

There are seven cervical (C1-C7) vertebrae. The top two are unique in form and number three through seven are similar in morphology. The uppermost is the atlas (C1) which supports the skull, and the next is the axis (C2), where much if the rotation takes place. The body of the atlas is the odontoid process of the axis (c2), and the atlas (c1) rotates around this.

your pelvis is connected to your femur, your femurs connected to your patella, your patellas connected to your tibia, your tibias connected to your fibula, your fibulas connected to your tarsal bones, your tarsal bones connected to your metatarsal bones, your metatarsal bones connected to your phalanges, your phalanges are connected to.... your toe nails?

Saying that the knee is "proximal" to the knee means it is closer to the center of the body. The construction of the leg allows us to walk. The knee couldn't be distal to the ankle because the foot would be located above the knee, which wouldn't connect to anything. It's really a matter of understanding the terminology...

Do you mean the ball joint in an automotive that is connected to the knuckle? Please write to 2459473@gmail.com for answer.

Red blood cells, in order to store more hemoglobin to carry oxygen, don't have a nucleus that can make repairs. So red blood cells only last, on average, 120 days. Because they constantly need to be reproduced and your bones, believe it or not, are very well vascularized, it seems like a pretty good place to store the marrow to make more red blood cells.

The first stage of ossification is the laying down of a cartilage template by chondrocytes. Then osteoblasts add calcium and phosphorus to the extracellular matrix. When that process is complete the osteoblasts become mature bone cells, osteocytes.

The smallest carpal bone is the pisiform, located on the palmar side of the wrist. It is a sesamoid bone, meaning it develops within a tendon. It is typically the smallest and pea-shaped among the carpal bones.

Bone cells store nutrients to make our bones strong enough to support our body. Bone cells also help your hormones develope.

...

Well, I'm not sure how much the bone cells can 'store' nutrients... the cell part is small in mass/volume compared to the mineral matrix of bone itself. The cells (osteoblasts technically) more just squirt out the squishy fibers and enzymes that allow those fibers to mineralize. That mass of mineralized matrix is 'bone' in the lay sense of the word. It's hard. It's a skeleton on which all our muscles are built. But it's not a solid mass of cells like our skin or muscles are.

There are a couple cells that are within this hard bone material--they're the osteocytes. They're little pipsqueak cells that aren't really big enough to do much and they're very very stuck in one position (just like Han Solo in carbonite). But they're holding 'hands' with one another and reaching out to the cells on the surface and they're not dead (you hope. it's big trouble if they die 'cause it can lead to osteonecrosis where your bone can crumble apart. and that sucks.), so the osteocytes probably do something.

There are osteoblasts--these little guys sit on bone in a plump little line and they squirt out the fibers that make up bone. But we've already covered this, yeah?

Then there are osteoclasts. These giant fellows look something like a cross between Jabba the Hut and a Pac-Man ghost, and they really are massive. The hungry fat kids of the bone world. They're also derived from a different side of the cellular family tree than the rest of the bone cells (hematopoietic stem cells vs. mesenchymal stem cells--which is probably the only way they had the machinery to blob together into one massive used-to-be-six-cells-but-now-is-one-giant-one cell). These big guys attach to bone and eat away at the bone. The borrow through it or leave big pits. Old people have too many osteoclasts (in ratio to osteoblasts) and so their bones keep getting smaller and smaller. But let's not be too hard on the osteoclasts, 'cause we've found out recently that you can't have healthy bone without them. Something to do with 'needing to remove the old before they can call in the new'. Figures. Oh! And these are the cells that break down calcium so you can have calcium ions in your bloodstream. This is wicked important--without these ions, your muscles and nerves won't work. That would suck.

There are also other bone cells, like bone lining cells.

It depends on what sort of bone cell you are talking about. Osteoblasts are specialized in so far as they form new bone only, osteoclasts digest bone for remodeling however cannot form new bone. However, there are other cells in bone, such as hemaotpoietic stem cells in the bone marrow that are only specialized in so far as they produce blood cells.

The ulna and the radius articulate with the distal humerus at the elbow joint. The ulna forms the primary articulation, while the head of the radius articulates with a small depression on the side of the ulna known as the radial notch.

Compact or cortical bone is hte hard, strong layer of bone.
