Trabecular bone.
Spongy inner layer called cancellous bone. Spongy bone is lighter and less dense than compact bone
Periosteum is the hard strong layer of bone
The inner layer of bone tissue, known as the trabecular or spongy bone, has a porous and lightweight structure. It feels less dense than the outer layer, which is compact bone, and is often softer and more flexible. This spongy texture helps to absorb shock and distribute weight, contributing to the overall resilience of bones. In terms of sensation, it is not typically felt directly, as bone is encased in other tissues and structures.
The first layer of the bone of the skull is the outer table, which is composed of dense, compact bone. This layer provides protection and strength to the skull, forming the outermost part of the cranial vault. Beneath the outer table lies the diploë, a spongy bone layer that contains bone marrow and contributes to the overall lightweight structure of the skull. The inner table, which is the innermost layer, is also made of compact bone and lines the cranial cavity.
The second layer of bone is called the compact bone. It is dense and hard, providing strength and protection for the inner layers of bone tissue. Compact bone is made up of osteons, which are closely packed units that form the bone's structure.
Compact bone is the outer region of all the bones in your body.There are two basic parts of each of your bones:There is an outer hard layer of bone called either compact bone or cortical bone. this layer is much more dense.There is an inner layer of bone called either cancellous bone or trabecular bone. This is a softer bone and contains bone marrow and much more blood vessels than the cortical (compact) bone.
No, bone marrow is not the outermost layer of the bone. The outermost layer of the bone is called the periosteum, which is a dense layer of connective tissue that provides support and protection for the bone. Bone marrow is found in the inner cavity of bones and is responsible for producing blood cells.
Bones have multiple layers to provide strength, resilience, and flexibility. The outer layer, known as the cortical bone, is dense and protects the inner structures, while the inner layer, called trabecular or cancellous bone, is lighter and helps absorb shock. This layered structure allows bones to withstand various forces and stresses while remaining lightweight. Additionally, these layers facilitate the production of blood cells and the storage of minerals.
The inner osteogenic layer primarily consists of osteoblasts, which are responsible for bone formation, as well as osteoprogenitor cells that can differentiate into osteoblasts. This layer is important for bone growth, repair, and remodeling.
the outer portionof most bones is a layer of hard compactbone called the "Cortex".
bone marrow
Bone has a complex texture that can be described as both dense and porous. The outer layer, known as cortical bone, is hard and smooth, providing strength and support, while the inner layer, or trabecular bone, has a spongy, honeycomb-like structure that helps absorb shock and reduce weight. This combination of textures allows bone to be both sturdy and lightweight, essential for its functions in the body. Additionally, bone surfaces may be rough due to the presence of microscopic features such as canals and ridges.
