Question 16

Slightly mobile fibrous joint

Answer 16

Syndesmosis

Question 17

Joints found in the skull and looked like a jigsaw puzzle

Sutures

Question 18

Type of the mobile joint that keeps the teeth in their sockets

Answer 18

Gomphoses

Question 19

Slightly mobile articulations

Answer 19

Cartilaginous

Question 20

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

Answer 20

Symphysis

Question 21

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

Answer 21

Synchondroses

Question 22

Fully mobile articulations

Answer 22

Sonovial joints

Question 23

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

Answer 23

Ball and socket joint

Question 24

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

Answer 24

Condyloid

Question 25

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

Answer 25

Saddle joint

Question 26

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

Answer 26

Hinge joint

Question 27

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

Answer 27

Pivot joint

Question 28

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

Answer 28

Gliding joint

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

Answer 30

Cortical bone

Question 31

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

Question 38

Are responsible for regulating bone repair and maintenance

Answer 38

Question 39

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

Answer 39

Osteoclasts

Question 40

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

Answer 40

Reactive stage

Question 41

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

Answer 41

Repairative stage

Question 42

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

Answer 42
