25% each of china clay and china stone.

Not all white blood cels are made in the bone marrows name three?

All white blood cells are produced from the hematopoietic stem cells that reside in the bone marrow. Some white blood cells, however, do not mature in the bone marrow but are transported to the thymus for maturation. These cells are collectively known as T (for thymus) cells and include helper (CD4+), cytotoxic (CD8+), regulatory (Cd4+/Foxp3+) and other types of T cells.

A hard bump feels like a bone under left foot right under toe it doesnt hurt only sometimes you cant see it only feel it had a xray but nothing showed up?

It is possible that the bump is a plantar fibroma, a noncancerous growth of fibrous tissue that can sometimes feel like a small bone under the foot. If the bump is not causing pain or interfering with daily activities, it may not require treatment. However, it is important to monitor it and see a healthcare provider if it changes in size or becomes painful.

What are the 3 major functions of bones in the body?

1. Support The skeleton or the frame work of bones is the framework of the body, it supports the softer tissues and provides points of attachment for most skeletal muscles. 2.Protection The skeleton provides mechanical protection for many of the body's internal organs, reducing risk of injury to them.

For example, cranial bones protect the brain, vertebrae protect the spinal cord, and the ribcage protects the heart and lungs. 3. Assisting in Movement Skeletal muscles are attached to bones, therefore when the associated muscles contract they cause bones to move. 4. Storage of Minerals Bone tissues store several minerals, including calcium (Ca) and phosphorus (P). When required, bone releases minerals into the blood - facilitating the balance of minerals in the body. 5.Production of Blood Cells The red bone marrow inside some larger bones (including, for example, the blood cells are produced.

6. Storage of Chemical Energy With increasing age some bone marrow changes from 'red bone marrow' to 'yellow bone marrow'.

Yellow bone marrow consists mainly of adipose cells, and a few blood cells. It is an important chemical energy reserve.

WHAT happens to bone after you are buried?

After burial, bones undergo decomposition due to the action of bacteria and other organisms in the soil. Soft tissues attached to the bones decompose first, followed by the bones themselves. Over time, bones may become mineralized and merge with the surrounding soil.

Are the bones in the humanskull separate?

Yes, the bones in the human skull are separate at birth but start to fuse together as a person grows. The skull is made up of several bones that eventually join together through a process called ossification.

How long does it take for a bruised bone to heal?

I just bruised mine snowboarding yesterday, it's still just as bad, but it get's alot worse I'd there is pressure or weight on it,so if you can avoid putting weight on it, I've heard it takes 3 days to a few weeks depending on how bad it is, you should go see a doctor about it if you have any major concerns.

Do the phalanges of the hand have the same function of the phalanges of the feet?

No. Definitely not. The arches of the feet allow humans to walk on two legs, allowing the phalanges of the hands to use tools. If you do not believe it, ask yourself which phalanges you would give up, those of your hands or feet, if you had to decide.

When a circumference is reduced by 6 why is the radius reduced by 1?

The equation relating the radius r of a circle to its circumference C is 2 * pi * r = C. If pi were equal to three, then this would simplify to C = 6r. Since pi is not exactly three, decreasing the circumference by 6 units will actually decrease the radius by a bit less than 1 unit.

What is the medical term meaning putting the broken ends of a fracture into alignment without the need of exposing the fractured bone by surgery?

The medical term is "closed reduction." This procedure involves aligning the broken ends of a fracture without the need for surgery. It is typically done manually or with traction.

Scapula is what type of bone?

The scapula is an irregular bone, and is defined as such because it is not a long, short, or thin bone. A long bone is longer than it is wide, for example the femur. Short bones are "cube shaped", such as the cuboid (one of your tarsal bones). Thin bones have a curve to them and are fairly flat, such as your sternum.

How do ansul systems work?

An ANSUL system is basically a fixed, wet chemical fire extinguisher. Instead of deploying it's agent through a hose like a portable extinguisher, it does so through fixed pipework that supplies agent to nozzles placed above the appliances, within the plenum and the extract duct system. A basic one tank system is described below.

The system normally has an automatic detection system, as well as a manual release mechanism (although electrical ANSUL systems are available, the mechanical systems are more cost effective and more popular). The automatic detection system consists of a steel cable that is always under tension. Within this line, detectors are placed that contain a heat rated fusible link. In the event of a fire and when the link reaches it's critical heat rating, the link seperates, releasing the tension and activates the system. The manual release is also a cabled system, but requires a pulling force to activate the system.

Both of these activation systems are wired back to a mechanical activation device known as an Automan unit which contains a mechanical activation unit, a pilot charge (normally nitrogen) in a pressurized cartridge, an agent tank and electrical switches for connection to gas shut-down and/ or in house fire panel.

On activation, the mechanical unit releases a "needle" which punctures a foil membrane on the gas cartridge. The gas passes through a regulator and is fed into the agent tank. This forces the agent out of the tank at a controlled rate, through the pipework and to dispersion nozzles placed at the appliances within the kitchen, as well as within the plenum and the extract duct system. The agent cools the fire as well as reacting with hot oils to form a foam blanket, cutting off the air supply to the fire.

Additional equipment, such as a regulated release unit, can be used to increase the size of the system and allow for additional tanks to be added to the system, based upon strict design calculations for the size of the appliance line(s) and the type of appliances.

Which pairs of bones form a lap?

The pelvic bones are the pair of bones that form a lap. These bones are the hip bones that come together to create a basin-like structure, known as the pelvis.

What organs does the skeletal system share with other systems?

The skeletal system plays a vital role in a variety of functions within the human body. One of the most important roles that the skeletal plays is the production of blood cells through the marrow located within the medullary cavity within the innermost portion of the bone. Long bones (femur, tibia, humerus, etc.) within the skeletal system are the primary locations where hematopoiesis (creation of blood cell components) occurs.

Another major role the skeletal system shares in the human body is that of locomotion. The bones are sites of origin and insertion for muscles, tendons, and ligaments. When all these work together in unison it allows us to move around. These various parts are actually part of the bone. The outermost layer of bone is that of the periosteum and this periosteum creates what is called an etheses. An etheses is where muscles, tendons, and ligaments directly attach to bone. In all actuality the tendons and ligaments are continuations of the outermost portion of the bone, the periosteum.

What are the 5 metatarsals called?

The metatarsals in the human foot are typically referred to as the first, second, third, fourth, and fifth metatarsals, starting from the inner side of the foot. Each metatarsal bone corresponds to one of the five toes.

Is there a bone in your derriere?

Yes, there is a bone in the derriere called the coccyx, also known as the tailbone. The coccyx is the final segment of the vertebral column in humans and serves as an attachment site for various muscles, ligaments, and tendons.

Displacement of a bone out of the socket is?

Displacement of a bone out of the socket is known as dislocation. It can lead to pain, swelling, and difficulty moving the affected joint. Immediate medical attention is needed to relocate the bone back into place and prevent further complications.

What functions as a watery skeleton against which muscles can work?

The circulatory system serves as a watery skeleton against which muscles can work. Blood provides support, oxygen, and nutrients to muscles while carrying away waste products, allowing muscles to contract and move efficiently. Additionally, the fluid-filled spaces within and surrounding muscles provide a cushioning effect, reducing friction and allowing for smooth movement.
