Bones and Joints Flashcards
synovial joint
extensive movement e.g TMJ, knee , ankle
at joint there is articular cartilage and also a capsule containing synovial fluid to reduce friction
what additional feature does the TMJ have in comparison to other synovial joints
additional bit of cartilage (articular disc) - fibrocartilage to smooth the joint movement
ligaments
connects bones and holds joints together
tendons
attach muscle to bones and allow movement
fibrous joints
no movement
connected via dense connective tissue and have no joint cavity
cartilaginous joints
little movement
no joint cavity
joined entirely by cartilage
symphysis
a cartilaginous joint in which the bones are joined via cartilage e.g sternum , ribs
paranasal sinuses
four air filled spaces surrounding the nasal cavity frontal maxillary ethmoid sphenoid
what is the largest of the paranasal sinuses
maxillary sinuses
found to the sides of the nose
where are each of the paranasal sinuses located
frontal - above eyes
maxillary - sides of nose
ethmoid - between eyes
sphenoid - behind eyes
vertebral foramen
hole in vertebra that spinal cord runs through
transverse process of vertebra
sticks out the sides
spinous process of vertebra
projection at back of vertebra that acts as a point of attachment for muscles and ligaments
what is vertebra C1 also known as
atlas
what is vertebra C2 also known as
axis
