Trabecular Vs Cortical Bone

Later there is more loss from cortical bone. Similarities between compact bone and spongy bone.

The Skeletal System Bone Structure Mcat 2018 Biology

They form the epiphyses bond ends of long bones.

Trabecular vs cortical bone. Both types of bone have an extracellular matrix with mineralized. These two types are classified as on the basis of porosity and the unit microstructure. The key difference between trabecular and cortical bone is that the trabecular bone is.

Thus this is an important difference between compact and trabecular bone. Compact bone is also known as the cortical bone while the trabecular bone is also known as spongy bone or cancellous bone. Location compact bone makes up the outer covering of bone while the trabecular bone makes up the inner cavity of a bone.

Dense cortical bone and spongy trabecular or cancellous bone differ in their architecture but are similar in molecular composition. Cancellous bone is highly vascular and frequently contains red bone marrow where hematopoiesis the production of blood cells occurs. Cortical bone versus trabecular bone structure.

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. Summary trabecular vs cortical bone. This was further explored in a 3 year sub study of the freedom trial.

Exchange of calcium ions. Actions of denosumab on cortical and trabecular bone. 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.

Both compact bone and spongy bones are structural bones. Cancellous bone also called trabecular or spongy bone is the internal tissue of the skeletal bone and is an open cell porous network. They are soft and light bones make up of loosely packed trabeculae.

Results from this head to head studies and the difference in the mode of action of denosumab compared to bisphosphonates suggested a difference in their effect on the diverse compartments of bones cortical and trabecular. Trabecular bone loss is prevented by estrogen in women and testosterone in men. Cancellous bone has a greater surface area and is ideal for metabolic activity e g.

The greater surface area also makes it suitable for metabolic activities such as the exchange of calcium ions. Cortical bone also known as compact bone and 2 trabecular bone also known as cancellous or spongy 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.

Bone in human and other mammal bodies is generally classified into two types 1. In osteoporosis cancellous bone is more severely affected than cortical bone.
