A&P bones chapter 6

acetabulum a socket in the pelvic bone where the thigh bone joins the pelvis
acromion highest part of the shoulder where the clavicle and scapula meet
articulation a joint which binds two bones together
ligaments connective tissue which binds bone to bone
skeletal muscles aka voluntary or striated muscles which attach to bone
smooth muscles muscles found in visceral organs and blood vessels
synovial joints freely moving joints
tendons connective tissue which binds muscle to bone
frontal bone front of the skull
occipital bone back of head and base of skull
temporal bones two temporal bones form the lower sides and part of the base of the skull
mandibular bone lower jaw bone
lacrimal bones thin and shaped somewhat like a fingernail; located at the inner corner of each eye
cervical vertebrae bones of the neck; C1-C7
thoracic vertebrae connect with the 12 pairs of ribs; T1-T12
lumbar vertebrae larger and heavier than the other vertebrae, support back and lower trunk; L1-L5
sacrum triangular-shaped bone; S1
coccyx tailbone
xiphoid process lower portion of the sternum
humerus upper arm bone
radius one of the two lower arm bones; thumb side
ulna one of the two lower arm bones; little finger side; has a large projection called the olecranon process (forms the point of the elbow)
carpals bones of the wrist; each wrist has 8 carpal bones
metacarpals form the bones of the hand; join carpals and phalanges
phalanges bones of the finger; each finger contains 3, but thumb only contains 2
ilium upper flared portion and largest of the 3 hip bones; good source for red bone marrow
iliac crest curved, upper edge of the ilium
ischium lowest part of the hip; strongest of pelvic bones
femur thigh bone; longest heaviest, and strongest bone in the body
patella kneecap; largest sesamoid bone; covers and protects the knee joint
tibia shin bone; located on the big toe side of the lower leg
fibula more slender of the two lower leg bones
tarsals known as the ankle bone; there are 7 in each ankle
metatarsals bones of the foot
phalanges toes; each toe has 3 but the great toe only contains 2
condyle knuckelike projection at the end of a bone
diaphysis main shaftlike portion of a bone
epiphyseal line (growth plate) layer of cartilage that separates the diaphysis from the epiphysis
epiphysis the end of the bone
false ribs rib pair 8-10, which connect to the vertebrae in the back but not to the sternum in the front
flat bones bones that are broad and thin with flat or curved surfaces; such as the sternum
floating ribs rib pairs 11 & 12
fontanelle soft spot
foramen hole in a bone through which blood vessels or nerves pass
hematopoiesis formation and development of blood cells in the bone marrow
intercostal spaces spaces between the ribs
intervertebral disc a flat, cirular platelike structure of cartilage that serves as a cushion (or shock absorber) between the vertebrae
long bones bones that are longer than they wide; such as the femur
ossification the formation of bone
osteoblasts immature bone cells
osteocytes mature bone cells
periosteum the thick, white, fibrous membrane that covers the surface of a long bone
short bones as long as they are wide; such as the wrist bone
sinus opening or hollow space
sulcus a groove or depression in a bone; a fissure
sutures immovable joints, such as those of the cranium
trochanter large bony process located below the neck of the femur
true ribs the first seven pairs of ribs; connect to the vertebrae in the back and to the sternum in the front
tubercle small rounded process of a bone
osteoporosis porous bone; loss of bone density
osteomalacia disease in which the bones become abnormally soft; called rickets
osteomyelitis infection of the bone; resulting from a bacterial infection that has spread to the bone tissue through the blood
spinal stenosis narrowing of the vertebral canal
kyphosis humpback
scoliosis abnormal lateral (sideward) curvature of a portion of the spine
closed fracture also known as a simple fracture; no open wound in skin
open fracture also known as a compound fracture; open wound in skin
compression fracture caused by bone surfaces being forced against each other
impacted fracture direct force causes the bone to break, forcing the broken end of the smaller bone into the broken end of the larger bone
colles' fracture occurs at the lower end of the radius, within 1 inch of connectin the wrist bones
hairline fracture also known as stress fracture
fracture broken bone; sudden breaking of a bone
pathological fracture occurs when a bone, weakened by a preexisting disease
closed reduction fracture consists of aligning the bone fragments through manual manipulation or traction without an incision int the skin
open reduction fracture consists of realigning the bone under direct observation during surgery
lordosis swayback
greenstick fracture incomplete fracture
DEXA scan (dual energy X-ray absorptiometry) noninvasive procedure that measures bone density
