Question

Describe in few words how the two types of bone tissue compact and spongy contribute to any given bone.

Answer 1

The two basic structural bone types are compact bone and spongy bone where they make up the long bones in the body. The long bones are dense hard bones which provide strength, structure and mobility. The spongy bones fills inner layer for most of the bones where as the compact bone fills outer layer of the bones.
     

Spongy Bones	Compact Bones
The Spongy Bones are also called cancellous bones	The Compact bones are also called cortical bones
They are light, spongy and soft in nature	They are heavy, tough and compact in nature
They are made up of trabeculae	They are made up of osteons
They fills the inner layer of most bones	They fills the outer layer of most bones
Bone-marrow cavity absent in spongy bones	Bone-marrow cavity present in the centre
Bone marrow produces red corpuscles and white granular corpuscles	Bone marrow stores fat
It forms the ends or epiphyses of long bones	It forms the shaft or diaphysis of long bones
