Chapter 4 The Musculoskeletal System— Orthopedics (TERMS) Flashcards
Bone starts as
Cartilage
Blood vessels penetrate the cartilage…
…and bone cells (osteocytes) begin the process of replacing the cartilage model with actual bone.
- process begins well before you are born and does not finish until puberty ends.
Many bones harden from the center…
outward
Some bones grow in a special growth center called
epiphyseal plate (also known as the growth plate)
growth center lies in the
metaphysis (area between the end of the bone(epiphysis) and the long shaft of the bone (diaphysis) )
Suffix for growth
-physis
The bones in the middle of the skeleton are called the
axial part of your skeleton
skull (cranio) is attached to your
spine
spine is made of many similar bones called
vertebrae that connect together
vertebrae protect
your spinal cord
Spine has 4 sections
- neck section (cervical)
-chest/upper back section (thoracic) - lower back (lumbar and sacral)
Ribs(costo) attach to the
vertebrae of the thoracic section
arms and legs branch off both sides of this central part of the skeleton
vertebrae of thoracic section
your upper arm (brachio) leads to the two bones of your
forearm(radius and ulna)
your upper arm (brachio) leads to the two bones of your forearm(radius and ulna), then to your wrist (carpe)
wrist (carpe)
your upper arm (brachio) leads to the two bones of your forearm(radius and ulna), then to your wrist (carpe), and finally to your
fingers (phalanges).
legs begin with your
thigh bone (femur)
legs begin with your thigh bone (femur), work down to the two
shin bones (tibia and fibula)
legs begin with your thigh bone (femur), work down to the two shin bones (tibia and fibula), move on to your
ankle (tarsal)
legs begin with your thigh bone (femur), work down to the two shin bones (tibia and fibula), move on to your ankle (tarsal), and ultimately reach your
toes (phalanges again like the fingers)

every bone in the body is connected to another except the
hyoid
the connection points between bones are known as
joints
Not all joints allow
movement (e.g. bones in your skull are bound tightly together)
moving joints allow motions like
bending and rotating
when a joint bends its called
flexion
when a joint straightens its called
extension
widening of a joint to move parts away from the body is
abduction
the joint narrows to bring parts back toward the body
adduction
holds muscle to bone
tendon
hold bone to bone
ligaments
surrounds bones at the joints and allows smooth movement among them
cartilage
under many tendons lie sacs of fluid, known as ___________ which help keep muscles and bones moving smoothly
bursae
root for cartilage
chondr/o
root for joint
arthr/o
root for bursa
burs/o
skeletal muscle is encased in a thick membrane called
fascia
fascia helps keep the muscle
together
skeletal muscles attach to bones their job is to
move the bones
muscles attach to bone via
tendons (which are thick bands of connective tissue)
root of tendon (connective tissue connecting muscle to bone)
ten/o, tend/o, tendin/o
root of muscle
muscul/o, my/o, myos/o
root for fascia (fibrous connective tissue binding muscles together)
fasci/o
root for tone, tension
ton/o
root for movement, motion
kinesi/o (also sometimes kinet/o)
root for arrangement, order, coordination
tax/o
root for stiff, bent
ankyl/o
