What are the functions of bones?
- form the skeleton
- provide the chief means of support for the body
- provide the mechanism for motion
- protect vital organs
- serve as a production factory for blood cells
- store calcium, phosphorus, and magnesium salts
What are the shapes of bones?
- long
- tubular
- short
- sesamoid
- cuboidal
- flat
long bones
longer that they are wide and found in the limbs (like the femur and humerus)
tubular bones
long bones
short bones
roughly cube shaped bones like carpal and tarsal bones
sesamoid bones
- short bone shaped like a sesame seed formed within the tendons
- cartilaginous in early life and osseous in the adult
- largest sesamoid bone in humans is the patella
cuboidal bones
short bones
flat bones
- consist of a layer of spongy bone between two thin layers of compact bone
- flat cross section, not rounded
- skull and ribs are examples
- have marrow but no marrow cavity
irregular bones
bones that don’t fit above, like the mandible and vertebrae
cartilage
a type of flexible connective tissue with no blood vessels
types of joints
fibrous, cartilaginous, synovial
synovial joints
- the most common type of joint
- articular cartilage that covers the bone ends
- joint cavity lined with a synovial membrane, which secretes a thick, viscid, slippery mucous that cushions the joint and allow smooth motion
- joint capsule of fibrous connective tissue that surrounds and provides stability of the joint
- accessory ligaments that give reinforcement
axial skeleton
skull hyoid ribs sternum vertebrae sacrum
appendicular skeleton
shoulder girdle
pelvic girdle
extremeties
closed fracture
does not involve a break in the skin
compound fracture
projects through the skin with a possibility of infection
comminuted fracture
more than two separate bone components (fragments)
transverse fraction
breaks shaft of a bone across the longitudinal axis
greenstick fracture
- only one side of the shaft is broken and the other is bent
- common in children
spiral fracture
spread along the length of a bone and produced by twisting stress
colles’ fracture
occurs in wrist and affects the distal radius bone
compression fracture
vertebrae collapse due to trauma, tumor, or osteoperosis
epiphyseal fracture
occurs when matrix is calcifying and chondrocytes are dying; usually seen in children
skeletal muscle
- also called striated muscle
- attached to the skeleton by tendons
- contraction of skeletal muscle is under voluntary control
cardiac muscle
- also called heart muscle
- contains interlocking involuntary striated muscle as well as smooth muscle
- allows the electrical impulses to pass quickly across the muscle fibers
smooth muscle
- found in the walls of all the hollow organs of the body (except the heart)
- contraction reduces the size of he structures
- movement is generally considered involuntary
ankylosis
condition of stiffening of a joint
arthralgia
pain in a joint
arthritis
inflammation of a joint
arthrodesis
surgical fixation of a joint
arthropathy
joint disease
bursitis
inflammation of the bursa
carpal
pertaining to the wrist bones
chondral
pertaining to cartilage
chondralgia
pain around and in the cartilage
coccygeal
pertaining to the coccyx
connective
tissue connecting or binding together
dactylic
pertaining to a finger or toe
femoral
pertaining to the femur (thigh bone)
iliac
pertaining to the ilium
kyphosis
abnormal curvature of the thoracic spine (humpback)
lordosis
abnormal anterior curvature of spine, usually lumbar (swayback or hollow back)
metacarpal
long bones of the hand that form the skeletal structure of the palm
osteoblast
bone-forming cell
osteocarcinoma
cancerous tumor of the bone
osteochondritis
inflammation of bone and cartilage
osteopenia
lower than average bone density; can be a precursor to osteoporosis
osteoporosis
condition resulting in reduction of bone mass
osteorrhaphy
suture of bone
patellar
pertaining to the patella
phalangeal
bones of the fingers and toes
scoliosis
lateral curvature of the spine
sternotomy
surgical incision of the sternum
tendonitis
inflammation of the tendon
What CPT code series pertains to the musculoskeletal system?
20,000 series
