Anatomy Of A Long Bone

Question 1

Cartilage

Answer 1

an articulating cartilage on both ends of a long bone. Allows articulation within joints and protects the ends of bones. No blood supply or nerve endings.

Question 2

Periosteum

Answer 2

the outer connective tissue that covers the whole bone. Ligaments, fibres, and tendons unite to connect bone/muscle to bone.

Question 3

Medullary cavity

Answer 3

found inside the shaft of the bone and is filled with red and yellow bone marrow. Red - blood cell formation occurs. Yellow - made up of fat cells mostly and connective tissue.

Question 4

Compact bone

Answer 4

the dense part of the bone. Responsible for structural integrity.

Question 5

Diaphysis

Answer 5

where the bone is at its thickest.

Question 6

Cancellous bone

Answer 6

filled with marrow in its small-cavity like spaces. Strengthens with exercise.

Question 7

Epiphysis

Answer 7

at the end of a long bone, the outer surface of it is made up of compact bone. The part that articulates with another bone is covered with cartilage.

Question 8

Epiphyseal plates

Answer 8

also known as growth plates, occur at different places at the epiphyses.

Question 9

Cortex

Answer 9

Exterior layer of bones. Is dense and smooth and of varying thickness. Interior core consists of networks and fibres that mesh with blood vessels and the bone marrow.

Question 10

Trabeculae

Answer 10

consists of bony fibres scattered in a strut like system. Runs throughout the cancellous tissue. The density varies with the type of bone and amount of stress it bears.
