What is the circumferential lamellae?
Circumferential Lamellae – Layers of bone matrix that go all the way around the bone. Spongy Bone. Trabeculae arranged along stress lines. Irregularly arranged lamellae and osteocytes.
What are the three types of lamellae found in compact bone?
Volkmann’s canals may be seen connecting haversian canals. The other lamellae of compact bone are organized into inner circumferential, outer circumferential, and interstitial lamellae. Only interstitial lamellae are seen in this slide.
What is the outer surface of bone is called?
The periosteum is a membranous tissue that covers the surfaces of your bones. The only areas it doesn’t cover are those surrounded by cartilage and where tendons and ligaments attach to bone. The periosteum is made up of two distinct layers and is very important for both repairing and growing bones.
Where is circumferential lamellae?
the circumferential lamellae (L) run around the circumference of the bone. The inner circumferential lamellae are located on the inner side of the compact bone tissue and the outer circumferential lamellae are located on the outside.
Where is circumferential lamellae located?
What is the perichondrium?
Perichondrium is a type of connective tissue, and also functions in the growth and repair of cartilage. Once vascularized, the perichondrium becomes the periosteum. [
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.
What is the interstitial lamellae?
the interstitial lamellae (K) fill the spaces between osteons. the circumferential lamellae (L) run around the circumference of the bone. The inner circumferential lamellae are located on the inner side of the compact bone tissue and the outer circumferential lamellae are located on the outside.
Where is concentric lamellae found?
A Haversian system is a series of concentric circles, called lamellae, found in the compact bone of humans. Compact bone is most often found in the shafts of the long bones of the human skeleton, like those found in the leg.
What is concentric lamellae?
concentric lamellae. The thin cylindrical plates, or layers of bone matrix (produced by osteoblasts ) around the minute vascular central canals in compact bone, which in cross-section produce a pattern of circles of different size, one within another, having a common center.
What is lamellae in bone?
lamella – a thin membrane that is one of the calcified layers that form bones. bone, os – rigid connective tissue that makes up the skeleton of vertebrates.
