long bone

Question 1

epihysis

Answer 1

Located on the ends of the bones
Made of compact bone on outside that surrounds the cancellous bone
Is the part that articulates with another bone

Question 2

epiphyseal line

Answer 2

seperates diaphysis and epiphysis

plates joined together

Question 3

cancellous bone

Answer 3

Sponge like structures (matrix) that contain marrow
Helps to absorb force on impact
Made of trabeculae: small bony fibers
Compact and Cancellous bone can be strengthened with resistance training

Question 4

diaphysis

Answer 4

the central section
it is made of dense bone around a medullary cavity (containing red and yellow marrow)
covered externally by a membrane known as the periosteum
medullary cavity lined (internally) by the endosteum

Question 5

epiphyseal plate

Answer 5

seperates diaphysis and epihysis

Question 6

medullary cavity

Answer 6

bone marrow, produce blood cells

Question 7

cortex

Answer 7

hard bone

Question 8

periosteum

Answer 8

Outer connective tissue that covers the entire bone; fibrous ; connects with ligaments and tendons to connect bone – bone and/or muscle to bone

Question 9

compact bone

Answer 9

thick, dense, structural rigitidy

Question 10

articular/hyaline cartilage

Answer 10

Located on both end of the long bone
No blood supply or nerve endings in the cartilage
Smooth surface to articulate with other bones in a joint; reduce friction

Question 11

trabeculae

Answer 11

Continuous bony fibres arranged in a strut-like system running throughout the cancellous tissue
Density varies depending on bone type
Vertebrae: compression, therefore thin structures with rigidity throughout trabeculae
Long Bones: Bending forces, therefore use tube-like structures
