Classification of bones
(i)Greater in length compared to their width.
(ii) Consisting of a shaft and a variable number of extremities (ends) that is called epiphysis (consisting of spongy bone tissue).
(iii) The diaphysis of the long bones is composed of compact bone tissue.
(iv) Slightly curved due to their strength
Example: Humerus, radius, ulna, femur, tibia, fibula and phalanges.
(i)Nearly equal in length and width.
(ii) Cube shapes.
(iii) Consisting of spongy bone tissue.
(iv) The surface is covered with a thin layer of compact bone tissue.
Example: Carpal bones, tarsal bones, trapezoid
Thin bones, composed of two nearly parallel plates of compact bone tissue covering a layer of spongy bone tissue.
Example: Cranial bones, sternum, ribs, scapulae.
(i)The shape can't be defined as any specific shaped bones.
(ii) The ratio of compact and spongy bones also varies remarkably.
Example: Vertebrae, hip bones, certain facial bones, calcaneus.
(i)Looks like sesame seeds.
(ii) Developed in certain tendons, where considerable friction and physical stress are there.
Example: Palms and soles.
Classification of bones, based on location
Small bones located in the joints (sutures) between cranial bones. The no of Sutural bones varies from person to person
