Movements and Terminology
Tunnel or hole for blood vessels and/or nerves
Foramen
End of bone, contains red bone marrow
Epiphysis
How many bones make up the skeletal system?
206
Slightly movable joints
Amphiarthrotic
One side of bone is broken and the other side bends, occurs in children whose bones have not yet fully ossified
Greenstick
Forearm movement turns palm face posteriorly or down
Pronation
Long central shaft, contains yellow bone marrow, made of compact bone
Diaphysis
What are the two divisions?
Axial and appendicular
Relatively flattened articular surfaces which slide across each other
Gliding
Occurs at distal end of fibula usually from an eversion ankle sprain
Pott's fracture
Smooth, rounded articular process; knuckle
Condyle
Growth plate, area where dialysis and epiphysis meet, where cartilage is reinforced and then replaced by bone
Epiphyseal line
Fluid filled sac to reduce friction, shock absorber
Bursa
What are the five categories of diarthrotic joints?
Ball and socket, hinge, pivot, gliding, saddle
Comparing injury to the uninjured spot on the opposite side of the body
Bilateral observation
Turning around on an axis (IR and ER)
Rotation
Dense fibrous covering around surface, essential for growth and repair and nutrition, point of attachment for ligaments and tendons
Periostium
What are the five classifications of bones?
Long, short, irregular, flat, sesamoid
What kind of joint is between axis (C1) and atlas (C2)?
Pivot
Inability or refusal to use the extremity because motion increases pain
Guarding
Location of the thumb opposite to the fingers so that the hand can grasp objects
Opposition
Thin layer of cartilage covering epiphysis, provides smooth gliding surface for a joint, helps protect ends of bone
Articular cartilage
What are the five functions of the skeletal system?
Support, protection, movement, storage, hemopoiesis (production of red blood cells)
Permits angular motion including circumduction, but prevents rotation
Saddle
Shattered at the site of fracture, smaller fragments between main fragments
Comminuted
