bones

cartilage

-part of connective tissue

-not a bone, but can become a bone

-located on edges of bone or w/in the bone itself

-joint is the junction between two bones or more and so cartilage provides smooth surface

skeletal cartilage

-water lends resiliency

-contains no blood vessels or nerves

-perichondrium (peri=around chondrium=cartilage): will find blood vessels + nerves

hyaline cartilage

-most common type of cartilage

-tough, somewhat flexible

-has collagen fibers

-function = reduces friction between bones

elastic cartilage

-elastic fibers

-resilient and flexible

fibrocartilage

-collagen fibers

-extremely durable

-w/in knee joints, between pubic bones, forms intervertebral disc

axial skeleton

-long axis of body

-includes skull, vertebral column, rib cage

appendicular skeleton

-full limbs + joints

long bones

longer than they are wide

short bones

-cube shaped bones, sesamoid bones

-vary in size + numbers depending on individual

-ex: carpal bones

flat bones

-thin, flat, slightly curved

-ex: ribs, most skull bones, etc.

irregular bones

-complicated bones (like vertebrae)
