Exam 1 Part four Flashcards
Joint between sternum and clavicle
Sternoclavicular joint
Joint between tooth and jaw
Gomphosis
Bursa
Sac filled with synovial fluid
Palm fases posteriorly
Pronation
Standing on tiptoe
Plantar flexion
Intervertebral disc has
anulus fibrosus and nucleus pulposus
Articulation among tibia, fibula, & talus
Talocrual joint
Menisci is located
in knee joint
The greatest range of mobility of any joint in the body is found in the?
Glenohumeral joint
The movement of the foot that turns the sole laterally is called
Eversion
A_____ is formed when two bones previously connected in a suture fuse
Synostosis
The ligament that helps to maintain the alignment of the condyles between the femur & the tibia and to limit the anterior movement of the tibia on the femur is the
Anterior cruciate ligament
The glenohumeral joint is primarily stabilized b the
Rotator cuff muscles that move the humerus
In a biaxial articulation
Movement can occur in two planes
A metacarpophalangeal (MP) joint, which has oval articulating surfaces and permits movement in two planes, is what type of synovial joint?
Condylar
What is a function of synovial fluid?
- Lubricates the joint
- Provides nutrients for articular cartilage
- Absorbs shock within the joint
What is the differences between fibrous joints and cartilaginous joints and synovial joints
Fibrous joints- occur where bones are held together by dense regular (fibrous) connective tissue
Cartilaginous joints- occurs where bones are joined by cartilage
Synovial joints-Has fluid-filled joint cavity that separates the cartilage-covered articulating surfaces of the bones. The articulating surfaces are enclosed within a capsule, & the bones are also joined by various ligaments
Describe all joints that are functionally classified as synarthroses
- Tooth to jaw
- Lambdoid suture (connects occipital & parietal bones)
- Epiphyseal plates in growing bones; costochondral joints
Describe the basic anatomy of the glenohumeral joint
Ball and socket joint formed by the articulation of the head of the humerus and the glenoid cavity of the scapula.
*Permits greatest range of motion of any joint in the body
Synarthrosis is
An immobile joint
Amphiarthrosis is
A slightly mobile joint
Diarthrosis is
A freely mobile joint
A gomphosis is
Resembles a peg in socket. The only ones in the human body are the articulations of the roots of individual teeth with the sockets of the mandible and the maxillae
Anatomy of synovial joints
Freely mobile atriculations. Bones in this joint are separated by a space called a joint cavity. These joints have several basic features: *An articular capsule *joint cavity *synovial fluid *articular cartilage *ligaments *nerves and blood vessels
All synovial joints are classified as
Diarthroses
