bones
provides shape and support for the body, as well as protection for some organs
Differences between male and female skeleton
male
heavier and possesses a narrow pelvic cavity, broader shoulders, and long rib cage
female
less heavy and possesses a wider pelvic cavity, narrow shoulders, and a shorter rib cage
Joints
Cartilaginous Joints
Synovial Joints
Fibrous Joints
pivot joint
saddle joint
gliding joint
ball & socket joint
Microscopic anatomy of bone tissue
compact bone is called an osteon, or Haversian system
Movements allowed by Synovial Joints
abduction (away), adduction (towards), extension (open), flexion (close), and rotation.
Disorders/diseases
Osteosarcoma
bone cancer that begins in the cells that form bones
Osteomyelitis
inflammation or swelling that occurs in the bone
Osteogenesis Imperfecta
genetic or heritable disease in which bones fracture easily, often with no obvious cause or minimal injury
Paget's Disease
chronic disease of elderly people characterized by deterioration of bone tissue
Osteoarthritis
protective cartilage
Anatomy of the long bone
endosteum
medullary cavity lined w/ thin layer
endosteum
medullary cavity lined w/ thin layer
medullary
diaphys hollow chamber
bone marrow
medullary cavity filled
periosteum
tough dense connective tissue
articular cartilage
covers epiphyses
epiphyses
expanded ends of bones
Bone remodeling
skeletal change where both protects the structural integrity of the skeletal system and metabolically contributes to the body's balance of calcium and phosphorus
Types of bones
long bone
long, thin shape
flat bone
flattened, broad surface
short bone
has a squat, cubed shape.
irregular bone
has a shape that does not conform to the above three types.
Bone fracture repair
fissured
incomplete longitudal break
commuted
complete and fragments the bone
greenstick
incomplete fracture, breaks occur on convex surface
transverse
complete, break occurs at right angle to axis of bone
oblique
occurs at angle
spiral
caused by excessive twisting of bone
