Amphiarthrosis, 



or Slightly 



Movable 



Joint 



Bones are con- 

 nected by 

 ili.sks of car- 

 tilage or in- 

 terosseous 

 ligaments. 



' 1. Symphysis. — The bones are 

 united bj' a plate or disk of fibro- 

 cartilage of considerable thickness. 

 Syndesmosis. — The bony surfaces 

 are united by an interosseous liga- 

 ment, as in the lower tibio-fibular 

 articulation. 



Diarthrosis, or 



Movable 



Joint 



Movement . 



, Fibrous liga- 

 ments form- 

 ing a capsule. 

 Synovial 

 ni e m b r a n e 

 lining fibrous 

 capsule. 

 Hyaline car- 

 tilage cover- 

 ing articular 

 ends of bones. 



Flexion. 

 Extension. 

 Abduction. 

 Adduction. 

 Rotation. 

 . Circumduction. 



1. Arthrodia. — Gliding joint ; artic- 

 ulates by i)lane surfaces which glide 

 upon each other. 



2. Ginglymus. — Hinge or angular 

 joint ; moves backward and for- 

 ward in one plane. 



3. Enarthrosis. — Ball and socket 

 joint ; articulates bj' a globular 

 head in a cup-like cavity. 



4. Trochoides. — Pivot joint ; articu- 

 lates by a pivot process turning 

 within a ring, or by a ring turning 

 round a pivot. 



5. Condylarthrosis. — Condyloid 

 joint ; ovoid head received into 

 elliptical cavity. 



6. Reciprocal Reception. — Saddle 

 joint ; articular surfaces are con- 

 cavo-convex.
