Which type of bone has lacunae in concentric circles around central canals and is found on the wall of the middle portion of a long bone?
Compact bone is organized as parallel columns, known as Haversian systems, which run lengthwise down the axis of long bones. These columns are composed of lamellae, concentric rings of bone, surrounding a central channel, or Haversian canal, that contains the nerves, blood vessels, and lymphatic system of the bone.
Which statement characterizes concentric lamellae of Osteons?
-It can be stimulated by stress on a bone. Which statements characterize concentric lamellae of osteons? -They are rings of bone tissue.
What is the thin layer of connective tissue that lines the medullary cavity of a long bone?
endosteum: A thin vascular membrane of connective tissue that lines the surface of the bone tissue that forms the medullary cavity of long bones.
Which letter indicates the region of a long bone that contains the medullary cavity?

What are the layers of the diaphysis?
The diaphysis is the shaft of long bones. This segment has an outer cortical shell of dense compact bone and an inner medullary cavity of spongy bone. Bone also has both an outer and inner connective tissue covering.
What tiny canal connects central canals to lacunae in compact bone?
Tiny passages or canals called canaliculi connect the lacunae with one another and with the central canal in each osteon.
What statements characterize central canals of Osteons?
it is also called a Haversian system. which statements characterize central canals of osteons? they contain osteocytes. they are also called lacunae.
What statements characterize lamellar bone?
Which statements characterize lamellar bone? -It is also called secondary bone. -It becomes the spongy bone of flat bones. -It becomes the compact bone of flat bones.
What is the medullary canal?
Medical Definition of medullary canal : the marrow cavity of a bone.
What type of bone is arranged in concentric layers?
The compact bone
The compact bone is a dense bone found in the diaphysis. Its repeated pattern is arranged in concentric layers of solid bone tissue. The compact bone can be seen as the layer just underneath the periosteum, color both ends.
What are concentric lamellae made of?
The osteons are made of osteocytes (I) arranged in circles and concentric layers of bone matrix (= concentric lamellae J). The concentric lamellae are like tubes of different size fitting inside each other to make an osteon.
Why doesn’t the periosteum cover the articular cartilage of a long bone?
The periosteum doesn’t cover the portion of bones that contains articular cartilage, which is the cartilage found in joints that keeps the bones from rubbing together. It is not as tightly packed and contains cells that help in bone growth and repair.
