Anatomy-Joints week 2 Flashcards
Explain joints
Meeting between 2 joints or more than 2 joints
List the 3 types of joints
- Fibrous
- Cartilaginous
- Synovial
What are fibrous joints?
2 bones connected by fibrous tissue, no movement
What are the 3 types of fibrous joints?
- Sutures of the skull
- Syndesmosis
- Gomphosis-tooth joint
Sutures
- Joints between the skull joints.
- Fibrous tissue is thin and may ossify
Syndesmosis
- Very strong ligaments between the 2 bones.
- Never ossify.
What are the 2 types of syndesmosis?
- Inferior tibiofibular joints
- Interosseous membrane
Inferior tibiofibular
Between the lower end of tibia and fibula
Interosseous membrane
Between the radius and ulna or between the tibia and fibula
Gomphosis
The joint between the tooth and the bone, never ossify
What are the characteristics of cartilaginous joints?
- Bones are connected together by cartilaginous tissue
- Allow limited movement.
What are the 2 types of cartilaginous joints?
- Primary cartilaginous joints
- Secondary cartilaginous joints
What are the characteristics of Primary cartilaginous joints?
- Bones are connected by hyaline.
- Temporary it ossifies- turns into bones
- Immobile
What are examples of the primary cartilaginous joint?
- Epiphyseal plate
- 1st sternocostal junction
What are the characteristics of secondary cartilaginous joint?
- Bones connected by fibrocartilage
- Permanent, doesn’t ossify.
- Limited movement.
What are examples of secondary cartilaginous joint?
All the midline joints
- Intervertebral disc between 2 vertebrae.
- Pubic symphysis
