Trabecular Vs Cortical Bone Histology

Cancellous bone also called trabecular or spongy bone is the internal tissue of the skeletal bone and is an open cell porous network. Begin by identifying the trabeculae the spongy network of bone tissue in the center of the bone.

Both compact bone and spongy bones are structural bones.

Trabecular vs cortical bone histology. Slide 70 developing bone. Between the trabeculae is the bone marrow. A trabecula generally has a mechanical function and is usually composed of dense collagenous tissue such as the trabecula of the spleen.

Primary bone or woven bone is characterized by the irregular arrangement of collagen fibers large cell number and reduced mineral content. 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. This type of bone is located between layers of compact bone and is thin and porous.

Contains the physis and the subchondral region under the articular cartilage. They form the epiphyses bond ends of long bones. Trabecular bone also known as cancellous bone or spongy bone mainly serves a metabolic function.

Later there is more loss from cortical bone. They are soft and light bones make up of loosely packed trabeculae. Secondary bone is further classified as two types.

Compact bone or cortical bone mainly serves a mechanical function. The surface of trabeculae are covered by a thin layer of inactive cells called endosteum. Summary trabecular vs cortical bone.

Cortical bone is also called compact or lamellar bone and provides strength to all the long bones of the body. 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. Trabecular bone also called cancellous or spongy bone and compact bone also called dense or 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. A trabecula plural trabeculae from latin for small beam is a small often microscopic tissue element in the form of a small beam strut or rod that supports or anchors a framework of parts within a body or organ. Trabecular bone loss is prevented by estrogen in women and testosterone in men.

Varied structure of either purely cortical bone or cortical bone with a thin central trabecular region. Similarities between compact bone and spongy bone. Trabecular bone this slide shows trabecular or spongy bone.

The sheath or outer shell formed by the cortical bone is called cortex. This is the area of bone to which ligaments and tendons attach. End of bone that forms the articular surface.

It is thick and dense. The greater surface area also makes it suitable for metabolic activities such as the exchange of calcium ions. Cortical bone refers to the thick outer surface of typically a long bone for example humerus or femur shaft that ensheathes the cavity of the bone called medulla.

The key difference between trabecular and cortical bone is that the trabecular bone is.
