Cortical Vs Trabecular Bone

Dense cortical bone and spongy trabecular or cancellous bone differ in their architecture but are similar in molecular composition. Compact bone is also known as the cortical bone while the trabecular bone is also known as spongy bone or cancellous bone.

Bone Basics

Cancellous bone has a higher surface area to volume ratio than cortical bone and it is less dense this makes it weaker and more flexible.

Cortical vs trabecular bone. Bone is a structural component that provides support for the movement act as a reservoir for amino acids phosphate calcium and bicarbonate raising of hematopoietic stem cells protection of interior organs etc. Varied structure of either purely cortical bone or cortical bone with a thin central trabecular region. Both types of bone have an extracellular matrix with mineralized.

Exchange of calcium ions. Cortical bone versus trabecular bone structure. In osteoporosis cancellous bone is more severely affected than cortical bone.

Bone loss after menopause is more rapid in the trabecular bone but because the cortical bone comprises 80 of the skeleton the absolute amount of bone loss is similar from each compartment for the first 10 years. The key difference between trabecular and cortical bone is that the trabecular bone is. Cancellous bone is highly vascular and frequently contains red bone marrow where hematopoiesis the production of blood cells occurs.

Cancellous bone has a greater surface area and is ideal for metabolic activity e g. Cancellous bone synonymous with trabecular bone or spongy bone is one of two types of osseous tissue that form bones. Summary trabecular vs cortical bone.

The high surface area facilitates trabecular bone having a higher metabolic activity compared to cortical bone. Cortical bone also known as compact bone and 2 trabecular bone also known as cancellous or spongy bone. 9 trabecular bone resembles a lattice like structure.

Trabecular bone loss is prevented by estrogen in women and testosterone in men. Location compact bone makes up the outer covering of bone while the trabecular bone makes up the inner cavity of a bone. Thus this is an important difference between compact and trabecular bone.

Compared to compact bone which is the other type of osseous tissue it has a higher surface area but is less dense softer weaker and less stiff. The greater surface area also makes it suitable for metabolic activities such as the exchange of calcium ions. Cancellous bone also called trabecular or spongy bone is the internal tissue of the skeletal bone and is an open cell porous network.

Bone in human and other mammal bodies is generally classified into two types 1. End of bone that forms the articular surface. Later there is more loss from cortical bone.

Contains the physis and the subchondral region under the articular cartilage. Trabecular bone sometimes referred to as cancellous bone is typically found at the ends of long bones and within the vertebral bodies trabecular bone has high porosity 70 80 with more space than bone fig. These two types are classified as on the basis of porosity and the unit microstructure.
