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
C1
first vertebra
does not have a body (C2 dens acts as its body)
joins the occipital bone
C2
second vertebra
has sticky up bit on body known as the dens which projects into C1
true ribs
7 (1-7)
directly attach to the sternum
false ribs
3 (8, 9, 10)
don’t directly attach to the sternum
floating ribs
2 (11, 12)
doesn’t attach to sternum
how does the size of the vertebra change as you move down the spinal cord
they increase in size to support more weight
what are the broad classifications of the foot bones
phalanges (toes)
metatarsals
tarsals
what are the broad classifications of the hand bones
phalanges (fingers)
metacarpals
carpals
