Joint Morphology

Question 1

Joint definition

Answer 1

Regions where adjacent bones are capped and held firmly together by other connective tissue

Question 2

3 types of joints

Answer 2

Fibrous, cartilaginous and synovial

Question 3

Two types of fibrous joints

Answer 3

Sutures, synchondroses

Question 4

Sutures explained and example

Answer 4

Allow no movement, bones held together by thin layers of dense connective tissue with osteogenic cells. Between skull bones

Question 5

Synchondroses explained and example

Answer 5

Allow more movement- interosseous membrane, distal tibial-fibular joint

Question 6

Two types of cartilaginous joint

Answer 6

Syndesmoses and symphyses

Question 7

Syndesmoses explained and example

Answer 7

Bones joint by dense connective tissue only, posterior region of the sacroiliac joint

Question 8

Symphyses explained and example

Answer 8

Thick pad of fibrocartilage between thin articular cartilage, pubic symphyses and intervertebral discs

Question 9

Synovial joint structure

Answer 9

Capsule of dense connective tissue that maintains proper alignment of the bones.

Capsule encloses sealed joint cavity.

Joint cavity contains synovial fluid.

Joint cavity lined by specialised connective tissue called the synovial membrane.
