Week 3 - Skeletal System Flashcards
Human Skeleton consists of how many bones
206
Periosteum
Covers the surface of the long bone
Red bone marrow
Site for blood cell production
Cranium
Bony skull (borders meet to form immovable joints)
immovable joints
sutures
Two bones provide distinctive shape to face
maxillae (upper jaw bones)
Mandible (lower jaw bones)
vertebral bones
24 vertebrae + sacrum + coccyx
What offers protection to spinal cord
vertebral bones
Cervical vertebrae
neck
cervic/o
C1 - C7
Thoracic vertebrae
chest
thorac/o
T1 - T12
Lumbar vertebrae
lower back
lumb/o
loins
L1 - L5
Coccyx
tailbone
Floating ribs
11 - 12
Completely free of attachment in front
Femur
thigh bone
Foot bones
Metatarsals
Osteomyelitis
Resulting from a bacterial infection that has spread to the bone tissue through the blood
Osteoporosis
Bones that were once strong becoming fragile due to loss of bone density
Osteogenic Sarcoma
Malignant tumor arising from bone also known as osteosarcoma
Spinal Stenosis
Narrowing of the vertebrae canal, nerve root canals, or intervertebral foramina
Talipes Equinovarus
Clubfoot
Abnormal Curvature of the spine
- Kyphosis
- Scoliosis
Kyphosis
outward curvature = humpback or hunchback
Scoliosis
lateral (sideward) curvature
Closed fracture
break in the bone but no open wound in the skin (simple fracture)
Open fracture
break in the bone, as well as an open wound in skin (compound fracture)
Complete fracture
break extends through the entire thickness of bone
Hairline fracture
minor fracture in which the bone continues to be in perfect alignment
Bone scan
intravenous injection of a radioisotope, which is absorbed by bone tissue
anterior view
front view
posterior view
back view
bone marrow aspiration
removal of a small sample of bone marrow from a selected site with a needle
