Q

Slightly mobile articulations

A

Cartilaginous

20
Q

Slightly less rigid than a true fused bone allowing minor binding and compression but no other motion

A

Symphysis

21
Q

Joint that is strong stable bond that connects the 2 bones and allow very little movement an example is the 1st rib and the sternum

A

Synchondroses

22
Q

Fully mobile articulations

A

Sonovial joints

23
Q

Joint made up of rounded persuasion of the distal bone articulating with the cup like depression of the proximal bone

A

Ball and socket joint

24
Q

This joint allows the distal bone to move forward and backward and side to side but does not permit the joint to rotate

A

Condyloid

25
Q

Joints that have a range of motion similar to the condyloid joint but their structure is very different

A

Saddle joint

26
Q

Very limited range of motion compared with the other joints similar to a door hinge

A

Hinge joint

27
Q

Also called rotary joints have a very limited range of motion they can twist

A

Pivot joint

28
Q

Also called planar joints are positioned between the flat surface of adjacent bones. Allow bones to move freely against each other on a single plane sliding in any direction as long as their smooth surfaces remain in contact

A

Gliding joint

29
Q

How long do bone cells live for

A

Ten years

30
Q

This type of bone is solid dense and hard it provides structural strength to the skeleton it makes up about 80% of skeletal weight

A

Cortical bone

31
Q

This type of bone is a porous network of thin needle like strands of bone its strange structure is similar to a honeycomb It makes up about 20% of the weight of the skeleton

A

Trebacular bone

32
Q

The center of long bones a hollow space

A

medullary

33
Q

Tough vascular membrane that surrounds and protects bones

A

Periosteum

34
Q

This lines the medullary cavity cavity of the longbones vascular lining contains bone forming cells that can repair trauma

A

Endosteum

35
Q

The tubalar structure consisted of lameller bone is called what

A

Haversian system

36
Q

The haversian commands are linked at right angles to each other by smaller passageways called what

A

Volkmanns canals

37
Q

Cells that create new bones

A

Osteoblast

38
Q

Are responsible for regulating bone repair and maintenance

A

Osteocytes

39
Q

Large cells with several nuclei that are found concentrated in small pits responsible for the resorption of old bone

A

Osteoclasts

40
Q

This occurs immediately following a fracture in the area surrounding the injury

A

Reactive stage

41
Q

This begins in the days following the fracture. Forms a callous which is a mass of fracture repairing tissue

A

Repairative stage

42
Q

Happens when the body replaces the trabecular bone with compact bone at the repair site. Processes slow and can take 3 to 5 years

A

Remodeling stage

43
Q

Measure the volume and density of bone in the skeleton at the end of skeletal maturation. The greatest mass tends to occur around the age of 30

A

Peak bone mass

44
Q

Bones are made up of a network of

A

College protein and minerals

45
Q

Primary center for osstification in longbones

A

Diaphysis
