Name the two types of fibrous joints
Sutures
Fibrous sheets
Where is the interosseous membrane located?
Between the radius and ulna and also between the tibia and fibula
The coronal suture is an example of which type of joint?
Fibrous
Name the to types of cartilaginous joints
Primary and secondary
Give an example of a primary cartilaginous joint
Epiphyseal growth plate
Give an example of a secondary cartilaginous joint
Intervertebral discs
What are fontanelles?
Wide sutures in the neonatal skull. All the growing frontal, parietal, temporal and occipital bones to slide over each other in “moulding”
Intervertebral discs are made up of an outer ____ and an inner ____
Outer fibrous anulus fibrosus and an inner soft nucleus pulposus
There are 7 typical features of synovial joints. Name at least 3 of these .
1/ 2 or more bones articulate with each other. 2/ The articular surfaces are covered by hyaline cartilage. 3/ A capsule wraps around the joint. 4/ Contains a joint cavity. 5/ Supported by ligaments 6/ Associated with skeletal muscle and their tendons 7/ Associated with bursa
Ligament attaches ___ to ___
bone to bone
Tendon attaches ___ to ___
Muscle to bone ( or vice versa)
The synovial joint cavity contains what? and what is it’s purpose
Synovial fluid which lubricates the joint and provides nutrients to the hyaline cartilage
What are the 5 types of synovial joint? Give an example of each
1/ Pivot (atlanto-axial) 2/ Plane (acromioclavicular) 3/ Hinge (elbow) 4/ Ball and socket (hip) 5/ Biaxial aka saddle (carpometacarpal)
What is subluxation?
The reduction of the area of contact between articular surfaces
What is dislocation?
The complete loss of contact between articular surfaces
Craniovertebral joint, TMJ and shoulder joints are ones that commonly…?
dislocate
The articulations of the TMJ are?
The mandibular fossa and the articular tubercle of the temporal bone superiorly and the head of the condylar process of the mandible inferiorly
What is the special feature of the TMJ?
The articular disc
A chin remaining in the midline suggests a unilateral or bilateral dislocation?
Bilateral
Describe the transverse thoracic plane
The plane between the sternal angle and T4/% vertebral interspace
The thoracic inlet is….
Bound by ribs 1, T1 vertebra and jugular notch
What is the area above the transverse thoracic plane ?
The superior mediastinum
What is in the anterior mediastinum
The thymus gland
What is the role of the thymus?
It produces T lymphocytes in childhood
