Definition Flashcards
musculoskeletal system
Means pertaining to the muscles and the skeleton
All of the bones, joints, muscles, and related structures that function in the movement of body parts and organs make up the musculoskeletal system.
musculoskeletal disorders
Cells of the musculoskeletal system are derived from stem cells that mature, and then begin to function, is bone cells, muscle cells, and so on.
bone marrow
Is the soft tissue that fills the cavities of the bones.
Red bone marrow
Functions in the formation of red blood cells, white blood cells, and platelets.
bones store
And release minerals, especially calcium in our essential parts of mineral balance in the body.
fat
Is stored in the yellow bone marrow.
Two types of bone marrow
Red bone marrow and yellow bone marrow
intracellular substance of a bone
Contains an abundance of mineral salts, primarily calcium phosphate, and calcium carbonate, which gives bone its unique hardness
endocrine system
Controls the release of calcium from the bone when the level of calcium in the blood is decreased.
most of the calcium in our bodies is stored in the skeleton.
chief characteristic of bone
Is its rigid nature, but it’s important to remember that bone contains living cells and is richly supplied with blood vessels and nerves. Like other body tissues, bone requires oxygen and nutrients and produces waste, the end products of metabolism.
Bones may be classified
As long, short, flat, or irregular.
Examples of
Long bones: in the arms, leg, and thigh
Short bones: in the wrist
Flat bones: most of the bones of the skull
irregular bones: bones of the spine
Compact bone 
Hard, dense bony tissue (major feature of a long bone)
os
( plural, ossa)
Is used to write the formal names of bones
diaphysis
The long shaft of the long bone. This long shaft is thick, compact bone, that surrounds yellow, bone marrow in adults.
Epiphysis
The ends of a long bone
The long shaft of a long bone is called the diaphysis, and the expanded portions at the ends are called…….
An expanded portion of each end of the diaphysis. The epiphysis is spongy bone that is covered by a thin layer of compact bone. The two ends are covered by articular cartilage to provide smooth surfaces for movement of the joints. Except in the areas where there is articular cartilage, the bone is covered with a tough membrane called periosteum.
peri/ost/eum
periosteum
around/bone/membrane
Most of the bone is covered with a tough membrane………….
Four types of bone tissue in the typical long bone
Periosteum: fibrous tissue that covers the bone
Compact bone: lies just beneath the periosteum and has a system of small canals (haversian canals) that run parallel to the bones long axis and contain blood vessels; canals are surrounded by concentric rings characteristic of the mature bone.
Spongy bone (Cancellous): lighter than compact bone and contains large spongy mesh works called trabecular: found largely in the epiphyses (plural form of epiphysis) and inner portions of long bones and is filled with red and yellow marrow
Yellow marrow: Found in the medullary cavity
haversia canals
they run parallel to the bone’s long axis and contain blood vessels; canals are surrounded by concentric rings characteristic of mature bone
trabeculae
large spongy mesh works, found largely in epiphyses (plural epiphysis) and inner portions of long bones and is filled with red and yellow marrow
medullary cavity
Calcium in bone
Is radiopaque; thus bones can obstruct x-rays so that they do not reach image receptors
calci/fication
calcification
is the process by which organic tissue becomes harden by deposit of calcium in tissue?
Normally calcium is deposited in bone in large amounts to give bone its hardness. Calcification in the soft tissue is abnormal.
myelo/blast

osteo/cyte
osteocyte
bone/cell

osteo/genesis
osteogenesis
is also called
ossification
bone/producing or forming
Formation of bones substance; same as ossification. Human embryos contain no bone but do contain cartilage, which is a more flexible tissue that is shaped like bone; ossification begins at the start of the fetal period (after the eighth week)
ossi/fication
ossification
Formation of bone substance
Is the development of bone
human embryos contain no bone but do contain cartilage, which is a more flexible tissue that is shaped like bone; ossification begins at the start of the fetal period after the eighth week

Includes the bones of the limbs and their attachments to the axial skeleton
many of these bones are small and are found in the hands and feet, but several of the remaining bones in this part of the skeleton are the longest bones in the body.
