Bone FAQs:

Q: Is bone a rigid organ that constitutes part of the vertebrate skeleton?

A: Yes.

Q: Is bone formed from connective tissue such as mesenchyme tissue rather than from cartilage?

A: Yes.

Q: Is bone not uniformly solid?

A: Yes, but includes a tough matrix.

Q: Are bones also a common site for other cancers to spread to?

A: Yes.

Q: Are bones a flight adaptation?

A: Yes.

Q: Is bone separated by a growing zone of cartilage?

A: Yes, At skeletal maturity , all of the cartilage is replaced by bone, fusing the diaphysis and both epiphyses together. In the upper limbs, only the diaphyses of the long bones and scapula are ossified.

Q: Is bone the osteon?

A: Yes.

Q: Is bone weakened?

A: Yes, such as with osteoporosis, or when there is a structural problem, such as when the bone remodels excessively or is the site of the growth of cancer.

Q: Are bones then often imaged?

A: Yes, and called radiography.

Q: Is bone managed according to their type?

A: Yes, and their stage, prognosis, and what symptoms they cause.

Q: Is bone produced when osteoblasts produce osteoid rapidly?

A: Yes, and which occurs initially in all fetal bones, but is later replaced by more resilient lamellar bone.

Q: Is bone inhibited by calcitonin and osteoprotegerin?

A: Yes.

Q: Are bones concerned?

A: Yes, and trabecular alignment has been studied in the vertebral pedicle.

Q: Is bone then formed by the osteoblasts?

A: Yes.

Q: Is bone constantly being created and replaced in a process known as remodeling?

A: Yes.

Q: Is bone reabsorbed and created the nature and location of the cells within the osteon will change?

A: Yes.

Q: Are bones composed of cortical bone also called compact bone being much denser than cancellous bone?

A: Yes.

Q: Were bones taken from?

A: Yes.

Q: Are bones the patella and the pisiform?

A: Yes.

Q: Is bone os?

A: Yes, and hence the many terms that use it as a prefix – such as osseous and osteopathy.

Q: Is bone typically found at the ends of long bones?

A: Yes, and near to joints and within the interior of vertebrae.

Q: Are bones used as an organic phosphorus-nitrogen fertilizer and as additive in animal feed?

A: Yes.

Q: Is bone called "primary" cancers?

A: Yes, although such cancers are rare.

Q: Is bone the trabecula?

A: Yes.

Q: Are bones characterized by a shaft, the diaphysis, that is much longer than its width?

A: Yes, and by an epiphysis, a rounded head at each end of the shaft.

Q: Is bone known as ossein?

A: Yes.

Q: Is bone formed, bone has a high compressive strength of about 170 MPa , poor tensile strength of 104–121 MPa, and a very low shear stress strength?

A: Yes, This means that bone resists pushing stress well, resist pulling stress less well, but only poorly resists shear stress. While bone is essentially brittle, bone does have a significant degree of elasticity, contributed chiefly by collagen.

Q: Are bones bones embedded in tendons?

A: Yes.

Q: Is bone laid down by osteoblasts?

A: Yes, and which secrete both collagen and ground substance.

Q: Is bone made?

A: Yes, and destroyed, or changed in shape.

Q: Are bones roughly cube-shaped?

A: Yes, and have only a thin layer of compact bone surrounding a spongy interior.

Q: Is bone "secondary" cancers?

A: Yes, and with the most common being breast cancer, lung cancer, prostate cancer, thyroid cancer, and kidney cancer.

Q: Is bone weaker, with a smaller number of randomly oriented collagen fibers, but forms quickly?

A: Yes, it is for this appearance of the fibrous matrix that the bone is termed woven.

Q: Are bones smaller and thinner?

A: Yes, and to aid flight.

Q: Is bone created after fractures or in Paget's disease?

A: Yes.

Q: Is bone constantly remodelled by the resorption of osteoclasts and created by osteoblasts?

A: Yes.

Q: Is bone highly vascular and frequently contains red bone marrow where haematopoiesis?

A: Yes, and the production of blood cells, occurs.

Q: Are bones thin and generally curved?

A: Yes, and with two parallel layers of compact bones sandwiching a layer of spongy bone.

Q: Is bone called ossification?

A: Yes.

Q: Is bone covered by a periosteum on its outer surface?

A: Yes, and an endosteum on its inner surface.

Q: Is bone treated with radiotherapy?

A: Yes.

Q: Is bone a process of resorption followed by replacement of bone with little change in shape?

A: Yes.

Q: Is bone formed by the hardening of this matrix around entrapped cells?

A: Yes.

Q: Is bone a metabolically active tissue composed of several types of cells?

A: Yes.

Q: Are bones filled exclusively with red marrow or hematopoietic marrow?

A: Yes, but as the child ages the hematopoietic fraction decreases in quantity and the fatty/ yellow fraction called marrow adipose tissue increases in quantity.
