Compact Bone vs Spongy Bone
Difference between Compact and Spongy Bone: Bones are the primary structure of vertebrate skeleton system which provides shape to the body and supports the muscles. Apart from this, the bone also produces the blood tissue. Based on the nature of bone-matrix, the skeletal bones are classified into two categories – (1) Compact bones and (2) Spongy bones.
(1) Compact bone: They are tough and heavy bones made of compactly packed osteons. They form the shaft or diaphysis of long bones.
(2) Spongy bone: They are soft and light bones make up of loosely packed trabeculae. They form the epiphyses (bond ends) of long bones.
Similarities between Compact bone and Spongy bone
@. Both compact bone and spongy bones are structural bones.
@. Both are the components of the skeletal system of an organism.
@. Both provide shape and structure to the organism.
@. Both are osseous tissues.
@. Both support the functioning of muscles.
Difference between Compact and Spongy Bone
Sl. No. Compact (Cortical) Bone Spongy (Cancellous) Bone 1 Also called as cortical bones Also called as cancellous bones 2 They are compact, heavy and tough in nature They are spongy, light and soft in nature 3 Forms the diaphysis (shaft) of long bones Forms the epiphyses (ends) of long bones 4 Compact bones fills the outer layers of most of the bones Spongy bones fills the inner layers of most of the bones 5 Made up of osteons Made up of trabeculae 6 Bone lamellae are arranged in regular Haversian system Bone lamellae are arranged as interlocking networks 7 No gaps between lamella Small spaces occurs between the bone lamella 8 Possess bone-marrow cavity in the center Bone marrow cavity absent 9 Bone marrow is located in the bone marrow cavity Bone marrow is located in the space between the lamella 10 Bone marrow is yellow in color Bone marrow is red in color 11 Bone marrow store fat Bone marrow produces red corpuscles and granular white corpuscles
