What type of connective tissue is found in long bones?
The outside of the bone consists of a layer of connective tissue called the periosteum. Additionally, the outer shell of the long bone is compact bone, then a deeper layer of cancellous bone (spongy bone) which contains in the medullary cavity the bone marrow….

What are the microscopic structures of a long bone?
Answer and Explanation: The microscopic structure of a long bone is an osteon or Haversian system that contains lamellae of compact tissue surrounding a central canal.
What tissues are found in the long bone?
The epiphyses, which are wider sections at each end of a long bone, are filled with spongy bone and red marrow. The epiphyseal plate, a layer of hyaline cartilage, is replaced by osseous tissue as the organ grows in length. The medullary cavity has a delicate membranous lining called the endosteum.
What are microscopic bone cells called?
osteoblasts
Osteocytes: These are mature osteoblasts that have become embedded in the bone matrix. They occupy small cavities (lacunae) in the bone and have protoplasmic projections con-nected with the same structure of other osteo-cytes. The osteocytes conform to the shapes of the lacunae.
Where is dense connective tissue found on a long bone?
The dense connective tissue on a long bone is found surrounding the shaft of the bone but does not cover the ends of the bone.
What type of tissue is bone tissue?
Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow).
What are microscopic structures?
Microscopic anatomy (micro; small) is a branch of anatomy that relies on the use of microscopes to examine the smallest structures of the body; tissues, cells, and molecules. The extent to which microscopic anatomy can be examined is limited by the equipment available.
What is bone connective tissue?
Abstract. Bone is a connective tissue containing cells, fibers and ground substance. There are many functions in the body in which the bone participates, such as storing minerals, providing internal support, protecting vital organs, enabling movement, and providing attachment sites for muscles and tendons.
What is long bone?
A long bone is a bone that has a shaft and 2 ends and is longer than it is wide. Long bones have a thick outside layer of compact bone and an inner medullary cavity containing bone marrow. The ends of a long bone contain spongy bone and an epiphyseal line.
What is fibrous connective tissue?
Fibrous connective tissue is composed of parallel bundles of collagen fibers. It is found in the dermis, tendons, and ligaments and can also be referred to as dense connective tissue.
Is bone dense connective tissue?
Ligaments are dense connective tissue that connect bone to bone and provide stabilization to a joint. Though ligaments are functionally different from tendons as they connect bone to bone, they are structurally similar.
What connective tissue are bones made of?
Bone, or osseous tissue, is a connective tissue that has a large amount of two different types of matrix material. The organic matrix is materially similar to other connective tissues, including some amount of collagen and elastic fibers. This gives strength and flexibility to the tissue.
Is tissue microscopic or macroscopic?
Microscopic anatomy (micro; small) is a branch of anatomy that relies on the use of microscopes to examine the smallest structures of the body; tissues, cells, and molecules.
What is microscopic structure of cell?
A cell consists of three parts: the cell membrane, the nucleus, and, between the two, the cytoplasm. Within the cytoplasm lie intricate arrangements of fine fibers and hundreds or even thousands of miniscule but distinct structures called organelles.
Is bone tissue a connective tissue?
Bone is a specialized connective tissue consisting of cells, fibers and ground substance. Unlike other connective tissues, its extracellular components are mineralized giving it substantial strength and rigidity.
Where is long bone?
All of the bones in the arms and legs, except the patella, and bones of the wrist, and ankle, are long bones.
Is bone a fibrous connective tissue?
The connective tissues include several types of fibrous tissue that vary only in their density and cellularity, as well as the more specialized and recognizable variants—bone, ligaments, tendons, cartilage, and adipose (fat) tissue.
Is tissue a microscopic?
Histology, also known as microscopic anatomy or microanatomy, is the branch of biology which studies the microscopic anatomy of biological tissues. Histology is the microscopic counterpart to gross anatomy, which looks at larger structures visible without a microscope.
Are tissues microscopic or macroscopic?
There are two major types of anatomy. Gross (macroscopic) anatomy is the study of anatomical structures that can be seen by the naked eye, such as the external and internal bodily organs. Microscopic anatomy is the study of tiny anatomical structures such as tissues and cells.
