Joints Flashcards
Connective Tissue
Tissues that share a common molecular composition
- They provide support and protection
What are the types of tissues?
- Connective tissues
- Muscle tissues
- Nervous tissues
- Dermal tissues
What are the types of connective tissues?
- Bones
- Cartilage (Hyaline, Fibro)
- Ligaments
- Tendons
- Joint capsules
-Fascia - Blood vessels
Tendons
Connect bone to muscle (force is applied in one direction)
Joint capsules
Surround joints (force is applied in all directions)
Flexion
Decrease in angle between body parts on either side of the joint
Extension
Increase in angle between body parts on either side of the joint
Abduction
Movement away from the midline in coronal/frontal plane
Adduction
Movement towards the midline in coronal/frontal plane
Medial rotation
Rotational movement towards the midline
Lateral rotation
Rotational movement away from the midline
Elevation
Moving superiorly
Depression
Moving inferiorly
Protaction
Moving anteriorly
Retraction
Moving posteriorly
How to determine solid joints
- No joint cavity present
- The bone surface is connected by stiff connective tissue (most often fibrocartilage)
- Allows little movement
How to determine synovial joints
- Have a small cavity between adjoining bones which are surrounded by a joint capsule
- The capsule is filled with synovial fluid which lubricates the joint surface
- Allow for movment
What are the types and movements of synovial joints?
Types:
- Planar -Hinge -Pivot -Bicondylar
- Condylar -Saddle -Ball and socket
Movement:
- Uniaxial (one plane)
- Biaxial (two planes)
- Multiaxial (three planes)
Label the synovial joint
