What is ground section of a bone?

A ground section of bone refers to a microscope slide of bone that is prepared by taking a larger piece of the bone and placing it between two pieces of abrasive material--such as carbide paper. These are rotated and "grind" the section down until the bone is adequately thin to transmit incident light in a light microscope, allowing for observation of the bone structure. This section is then transferred to a glass slide, mounted, and cover slipped. Most histologic sections of bone are prepared by paraffin embedding of the tissue and cutting the tissue on a microtome. in the case of bone, however, the hydroxyapatite mineral must be removed prior to paraffin embedding so that the paraffin and tissue will have uniform hardness and produce even cutting and adequately thin sections. In a ground section, there is no need to remove the mineral, so that the bone in the section contains both the mineral and the collagen that form most of the bone structure. It should be noted, however, that the process of grinding produces excess heat from the friction of grinding. This heat removes the cellular elements from the bone, so that ground sections are only used to study the non-cellular, mineralized portions of a piece of bone that persist after the frictional heat has burned off the bone cells.

What if a broken bone was never set?

Many bones actually set them selves after being broken.

It do depend on what bone it is and where it is broken.

If not checked and possibly realigned by a doctor, the bone may grow back together at an angle. This may cause further discomfort later.

Some bone splinters may never grow back in place and might cause terrible agony now and then.

Which gland regulate the exchange of calcium between bones and blood?

The parathyroid gland regulates the exchange of calcium between bones and blood by secreting parathyroid hormone (PTH). PTH helps increase blood calcium levels by stimulating the release of calcium from bones and enhancing absorption of calcium in the intestines and kidneys.

Scientific name of ankle bone?

tarsals.

talus is the name of the ankle bone, Tarsus is the general name for the group of bones of the foot, excluding the bones of the toes. In general, the articulations between the leg bones and the toes.

[And just to confuse things, tarsus is also the name of the plate of tissue in your eyelid.]

BTW, geologists use talus for the curve of debris at the foot of a cliff - the association is two fold, it has a curve like an ankle; and it is at the foot of the cliff.

What is the scientific name for the rib cagge?

Ribcage is the scientific name.
The rib cage defines the thorax, or upper body, so the medical term for rib cage is 'thoracic cage'. (Thore -ASS-ik)

I am not toally sure but i think that the isn't really a specific treatment of a broken bone. There's not much a doctor can do for you other than put the broken bone in plaster to support and straighten the broken bone.

What is the function of the calcium salts in the long bone?

Bone is a composite material, like fiberglass (something hard [and thus brittle] in a matrix of a more flexible substance.

In fiberglass the glass makes the (fishing rod) strong, the plastic makes it tough.

In bone, the calcium salts make it strong and hard, the connective tissue makes it tough.

What does red bone marrow produce?

red blood cells and white blood cells and platelets

How many bones does children have?

Your skeleton contains 206 bones.when you were a child, you had 208 bones. An infant may have as many as 350 bones, as the child grows older, many of these bones fuse to become single bones.

What is the scientific name for palm bone?

The hand is one of the more complex features of the skeletal system. The first and foremost reason is that the hand is not made from 1-2 connecting bones. In fact, the hand contains exactly 27 bones connected by ligaments and other soft tissue.

The palmar (palm) region of the hand contains 8 of the 27 bones known as the Carpals.

What are the main bones in the skeletal system?

The five major jobs of the skeletal system: protection, movement, shape and support, stores minerals and makes blood cells. These are the five major jobs of the skeletal system. Some organs are teeth, bones, ligaments, and cartilage.

Bone.

What is a supernumerary bone?

"Accessory (supernumerary) bones develop when additional ossification centers appear and form extra bones. Many bones develop from several centers of ossification, and the separate parts normally fuse. Sometimes one of these centers fails to fuse with the main bone, giving the appearance of an extra bone; but careful study shows that the apparent extra bone is a missing part of the main bone. Circumscribed areas of bone are often seen along the sutures of the cranium where the flat bones abut, particularly those related to the parietal bone. These small, irregular, worm-like bones are sutural bones. It is important to know that accessory bones are common in the foot, to avoid mistaking them for bone fragments in radiographs and other medical images". Moore & Dalley. Clinical Oriented Anatomy. 5th edition. pg 21.

The extra bones that sometimes develop between the flat bones of the skull are called?

The extra bones that sometimes develop between the flat bones of the skull are called sutural (wormian) bones. These are small accessory bones that can vary in size and number among individuals.

What kind of joint is in the knee?

The knee joint is a hinge joint that allows for flexion and extension of the leg. It is formed by the articulation between the femur (thigh bone) and tibia (shin bone), as well as the patella (kneecap).

What is the benefit of having a stiff rib cage surrounding the thoracic cavity?

It prevents traumatic blows from damaging the soft tissue that lies below it, e.g. the lungs, heart, stomach, liver, spleen etc. It also provides an attachment for the lung pleura aiding lung compliance.

How many saddle joints are in the human body?

There is one saddle joint in the human body, which is the carpometacarpal joint of the thumb. This joint allows for a wide range of motion, including flexion, extension, abduction, adduction, and opposition.

What type of joint is found at the knee?

The knee joint is a hinge joint, allowing movement in one plane like a door hinge. It is classified as a synovial joint, allowing for flexion and extension of the leg. The knee joint is formed by the articulation of the femur, tibia, and patella.

What is purpose of the rib cage?

The rib cage serves to protect the vital organs in the chest, such as the heart and lungs, from injury. It also helps to support the structure of the chest and aids in breathing by expanding and contracting during respiration.

What makes bones so strong?

Weight lifting and overall physical activity will help strengthen bones. Maintaining strong bones also means having a rich share of calcium. Vitamin D can actually help your body to absorb calcium as well.

How many bones are in the mandible?

In vertebrates, the lower jaw, dentary or mandible is the mobile component that articulates at its posterior processes, or rami (singular ramus), with the temporal bones of the skull on either side; the word jaw used in the singular typically refers to the lower jaw. The upper jaw or maxilla is more or less fixed with the skull and is composed of two bones, the maxillae, fused intimately at the median line by a suture; incomplete closure of this suture and surrounding structures may be involved in the malformation known as cleft palate. The maxillary bones form parts of the roof of the mouth, the floor and sides of the nasal cavity, and the floor of the orbit (eye socket). The jaws typically accommodate the teeth or form the bases for the attachment of a beak.

True or false Only bones can be fossilized soft tissue cannot?

False. Soft tissues can also be fossilized under certain conditions, although it is much more rare compared to the fossilization of bones. Soft tissue preservation can occur in exceptional cases, such as in the fossilized remains of animals found in frozen environments like the ice age.

What is a painful hard lump going from left rib to side of body to back causing pain breathlessness discomfort?

This could potentially be a symptom of a rib injury, muscle strain, or even a more serious condition like a kidney stone. It's important to see a healthcare professional for proper diagnosis and treatment.
