chapter 14 Flashcards
periosteum
outermost layer of the bone, made up of fibrous tissue
compact bone
dense, hard layers of bone tissue, lie underneath periosteum
cancellous (spongy) bone
contains little spaces like a sponge and is encased in layers of compact bone
endosteum
membranous lining of hollow cavity of bone
diaphysis
shaft of the long bone
epiphysis
end of each long bone
bone marrow
material found in cavities of bones
red marrow
thick, bloodlike material
found in flat bones & @ ends of long bones
location of blood cell formation
yellow marrow
soft, fatty material found in medullary cavity of long bones
maxilla
upper jawbone
mandible
lower jawbone
vertebral column
made up of vertebrae through which the spinal cord runs
protects spinal cord, supports the head, provides points of attachment for ribs and muscles
cervical vertebrae (C1-C7)
first set of 7 bones, forming the neck
thoracic vertebrae (T1-T12)
second set of 12 vertebrae, articulate with the ribs, form outward curve of spine
lumbar vertebrae (L1-L5)
third set of 5 vertebrae, larger, form outward curve of the spine
sacrum
5 vertebrae, fused together to form a triangular bone positioned between the two hip bones
coccyx
4 vertebrae fused together to form the tailbone
lamina
part of the vertebral arch
clavicle
collarbone
scapula
shoulder blade
acromion process
extension of the scapula, forms the high point of the shoulder
sternum
breastbone
xiphoid process
lower portion of the sternum
humerus
upper arm bone
ulna & radius
lower arm bones
olecranon process
projection at upper end of ulna that forms the bony point of the elbow
carpal bones
wrist bones
phalanges
finger and toe bones
metacarpal bones
hand bones
pelvic bone, hip bone
made up of three bones fused together
ischium
lower, rear portion on which one sits
ilium
upper, wing-shaped part on each side
pubis
anterior portion of the pelvic bone
acetabulum
large socket in the pelvic bone for the head of the femur
tibia & fibula
lower leg bones
femur
upper leg bone
patella
kneecap
tarsal bones
ankle bones
calcaneous
heel bone
metatarsal bones
foot bones
articular cartilage
smooth layer of firm, fibrous tissue covering the contacting surface of joints
meniscus
crescent shaped cartilage found in the knee
intervertebral disk
cartilaginous pad found between the vertebrae in the spine
pubic symphysis
cartilaginous joint at which two pubic bones come together
synovia
fluid secreted by the synovial membrane and found in the joint cavities
bursa
fluid filled sac that allows for easy movements of one part of the joint over the other
ligament
flexible, tough band of fibrous connective tissue that attaches one bone to another at a joint
tendon
band of fibrous connective tissue that attaches muscle to bone
aponeurosis
strong sheet of tissue that acts as a tendon to attach muscle to bone
skeletal muscles (striated)
attached to bones by tendons and make body movement possible, voluntary muscles
smooth muscles (unstriated)
located in internal organs, involuntary muscles
cardiac muscle (myocardium)
forms most of the wall of the heart, involuntary contraction produces heartbeat
abduction
moving away from the midline
adduction
moving toward the midline
inversion
turning inward
eversion
turning outward
extension
movement in which a limb is placed in a straight position
flexion
movement in which a limb is bent
pronation
movement that turns the palm down
supination
movement that turns the palm up
rotation
turning around its own axis
