what is cancellous bone?
-spongey bone
what are the beams called in cancellous bone?
-trabecular
how does cancellous bone get stronger?
-through force against it
what does red bone marrow produce?
-blood cells
what does articular cartilage do?
-prevent friction
what is the nutrient artery?
blood vessels in holes in the bone that collect blood cells
what does yellow bone marrow produce?
fat and cartilage
what is the epiphysis?
-rounded end of the bone
-forms an articulation/joint
whats the diaphysis?
central shaft
what is the epiphyseal line?
disc of cartilage found at the end of each bone
what is compact bone?
-hard tissue surrounding bone
-known as cortical bone

description of notches?
depression in a bone which often provides stabilisation
location of notches?
radius and ulna
description of a fossa
-a shallow depression in the bone surface
-supports brain structures
location of a fossa
cranium
description of condyles?
large area which protects hyaline cartilage(cushion for cartilage)
location of a condyle?
-knee hinge joint
description of processes?
-raised,sharp elevation of bone where muscle and connective tissue is attached
-provides protection
location of a process?
vertebrae column
description of a tuberosity?
-muscle and connective tissue attach
