Chapter 9 Introduction- Fibrous Joints (Part 1)

joint (articulation)

any point where two bones meet, whether or not the bones are movable at that interface

Arthrology

Science of joint structure, function, and dysfunction

Kinesiology

the study of musculoskeletal movement

Joint Name

typically derived from the names of the bones involved

Joints Classified

In which the adjacent bones are bond to each other, with differences in how freely the bones can move

Joints

• bony joints

• fibrous joints

• cartilaginous joints

• synovial joints

Synostosis

Another name for bony joints

Bony Joint

immovable joint formed when the gap between two bones ossifies, and the bones become single bones

bony joints

can occur in either fibrous or cartilaginous joint

Synarthrosis

Another name for fibrous joints

Fibrous Joints

A point at which adjacent bones are bound by collage fibers that emerge forom one bone and penetrate to another

fibrous joints

• sutures

• gomphoses

• syndesmoses

Sutures

immovable or slightly movable fibrous joints that closely bind the bones of the skull to each other

Sutures

• serrate

• lap

• plane

Serrate suture

interlocking wavy lines

lap (squamous) suture

overlapping beveled edges

plane (butt) suture

straight non overlapping edges

serrate suture

coronal, sagittal, and lamboid

lap (squamous) suture

temporal and parietal bones

plane (butt) sutures

palatine processes of the maxillae

Gomphoses

attachment of a tooth to its socket

gomphosis

held in place by fibrous periodontal ligament

gomphoses

allows the tooth of move a little under the stress of chewing

Syndesmosis

a fibrous joint at which two bones are bound by longer collagenous fibers

less movable syndesmosis

tibia to fibula

most moveable syndesmosis

radius to ulna
