Type of synovial joints?
- Plane Joints
- Pivot Joints
- Bicondylar Joints
- Condylar (ellipsoid joints)
- Saddle joints
- Ball and socket
Fibrous Joints include?
- Sutures
- Gomphoses
- Syndesmoses
Cartilaginous Joints?
- Synchondroses
- Symphyses
Factors limiting movement?
- Tension in ligaments
- Tension in the antagonist muscles
- Approximation of soft tissue
- Bony apposition
Closed pack position?
When joint surfaces reaches its best fit and joint structures are tensioned
Open packed position?
Joint structures are not under tension and described as loose packed
3 types of muscles in body?
- Cardiac
- Smooth
- Skeletal
3 different types of fibres?
- Slow oxidative- Type 1
- Fast oxidative- Type 2a
- Fast Glycolytic- Type 2b
Functions of skeletal muscle?
- Produce movement
- Maintain posture against gravity
- Help produce body heat
- Give contour to the body
Fixator?
Steadies the base, and stabilises the proximal attachment of the agonist
(e.g when flexing hip, core muscles stabilise)
Synergist?
Improves quality and control, by preventing unwanted movements in adjacent joints (e.g joints connecting bones in vertebral body)
Active Insufficiency?
(Agonist) - A muscle, which passes over two joints and cannot actively shorten sufficiently to produce full range of movement at both joints
Passive Insufficiency?
(Antagonist)- A muscle, which passes over two joints, can not be passively lengthened enough to allow full range of movement at both joints
