Muscoloskeletal system Flashcards
what are the parts of the appendicular skeleton?
limbs
What are the parts of the axial skeleton?
head, neck, trunk
Cartilage provides?
flexibility (ribs) and reduces friction (articular)
__-round bones that develop in tendons that pass over/around joints
sesamoid bones
what do the terms foramen, canal, and fissure mean?
opening
What do the terms fossa and sulcus mean?
depressions
Joints can be classified as fixed or moveable, they also can be classified based on how participating bones are united for example:
fibrous joints and cartilagenous joints–> both fixed
synovial joints–> moveable, have a cavity

suture= ____
teeth= gomphosis syndesmosis = long bones connected by interosseous membrane suture= skull
