Types of joints

Question 1

joins bones with a fibrous joint capsule that is continuous with the periosteum of the horned bones; filled with synovial fluid; hyaline cartilage lining both edges of bone

Answer 1

Synovial joint (diarthrosis)

Question 2

bones connected entirely by cartilage

Answer 2

cartilaginous joint (amphiarthosis)

Question 3

bones connected by dense connective tissue; mainly collagen

Answer 3

fibrous joint (synarthrosis)

Question 4

synovial; non-axial (no bending across axis); glides and slides; acromioclavicular joint

Answer 4

Planar joint

Question 5

hinge; uniaxial; thin slack joint capsule (elbow)

Answer 5

Ginglymus (hinge)

Question 6

pivot; uniaxial rotation; atlantoaxial joint (pivots around the Dens)

Answer 6

Trochoid (pivot)

Question 7

one or two concave surfaces articulating with one or two convex surfaces; biaxial; metacarpophalangeal joint

Answer 7

Condyloid or condylar joint

Question 8

both convex and concave surfaces; biaxial; allows false circumduction without rotation

Answer 8

Sellar or saddle joint

Question 9

multiaxial, allows circumduction; hip and elbow

Answer 9

spheroidal or ball and socket

Question 10

Peg in socket joint joined by fibrous connective tissue

Answer 10

gomphosis joint (fibrous)

Question 11

Tongue in groove joint joined by fibrous connective tissue

Answer 11

Schindylesis (fibrous)

Question 12

two bones separated by fibrous membrane (sheet)

Answer 12

syndesmosis (fibrous)

Question 13

usually transient (only when bone is growing); temporary union of hyaline cartilage between diaphysis and epiphysis

Answer 13

Synchondrosis (primary cartilaginous joint)

Question 14

strong, slightly movable joints united by fibrocartilage

Answer 14

Symphysis (secondary cartilaginous joint)
