What is the microscopic structure of bone and cartilage?

Microscopic Structure Under microscopic examination, it is found that the cellular elements of the bone contribute to the total mass of the bone to only a small extent. Compact bone is composed of bone matrix or lamellae. These are arranged concentrically around a longitudinal channel, or Haversian canals.

What is the microscopic structure of a bone?

The basic microscopic unit of bone is an osteon (or Haversian system). Osteons are roughly cylindrical structures that can measure several millimeters long and around 0.2 mm in diameter. Each osteon consists of a lamellae of compact bone tissue that surround a central canal (Haversian canal).

What color is compact bone?

Compact bone, also called cortical bone, surrounds spongy bone and makes up the other 80% of the bone in a human skeleton. It is smooth, hard and heavy compared to spongy bone and it is also white in appearance, in contrast to spongy bone which has a pink color.

What are the microscopic structures of compact bone?

The microscopic structural unit of compact bone is called an osteon, or Haversian system. Each osteon is composed of concentric rings of calcified matrix called lamellae (singular = lamella).

How are cartilage and bone structurally similar?

Cartilage and Bone are specialised forms of connective tissue. They are both made up of cells embedded in an extracellular matrix. It is the nature of the matrix that defines the properties of these connective tissues. Cartilage is thin, avascular, flexible and resistant to compressive forces.

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 yellow marrow How do spongy and compact bone look different?

What is yellow marrow? How do spongy and compact bone look different? Yellow marrow: Substance composed of fat found in the medullary cavity of long bones in adults. Spongy bone looks cancellous, whereas compact bone appears to be solid, smooth, and dense.

Are bones yellow?

The bone marrow of full grown adults is about half red and half yellow. Bones are made of four main kinds of cells: osteoclasts, osteoblasts, osteocytes, and lining cells.

What color is cancellous bone?

CANCELLOUS (spongy) BONE (e) and MARROW (e) – red The cancellous bone is found mainly within the epiphysis and has a textured appearance where it contains red marrow. Color both ends.

Which statement correctly identifies a similarity between cartilage and bone?

Which statement correctly identifies a similarity between cartilage and bone? – Both are produced by specialized mesenchymal cells. – Both are avascular.

What are the similarities and differences between bone and cartilage?

Difference between Bone And Cartilage

Basis of Comparison	Bone	Cartilage
Cell Name	Bone cells are called osteocytes	Cartilage cells are called chondrocytes
Growth	Bidirectional. They grow in both directions.	Unidirectional. It grows in a single direction
Bone Marrow	It is present	It is absent
Blood Vessels	Present	Absent

What are the microscopic structures of skeletal muscle?

Each myofibril consists of two types of protein filaments called thick filaments and thin filaments. The thick filaments and the thin filaments within myofibrils overlap, and the sections where they overlap and occur together are called sarcomeres.

What color are human tears?

Tears are a clear liquid secreted by the lacrimal glands (tear gland) found in the eyes of all land mammals.

Where is Red Bone Marrow found?

Red bone marrow is primarily found in the medullary cavity of flat bones such as the sternum and pelvic girdle. This type of bone marrow contains hematopoietic stem cells, which are the stem cells that form blood cells.

How are compact and spongy bone tissues different in microscopic appearance location and function?

Both compact and spongy bone tissues have the same types of cells, but they differ in how the cells are arranged. The cells in the compact bone are arranged in multiple microscopic columns, whereas the cells in the spongy bone are arranged in a looser, more open network.

What is bone white color?

Bone White is a light, neutral, yellow white with a green undertone. It is a perfect paint color for all the walls of a room. Pair it with warm neutrals. This color is also part of our Harmony collection (PPG14-22).

What colors are bones?

Bones are whitish because of their chemical composition. When alive, bones are white~yellow~red because of the mineral, fat and bloody components. Dead dry bone is white because of calcium phosphate which makes up a large portion of the mineral content.

What color is bone marrow?

There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow marrow is made mostly of fat.

What feature is found in both cartilage and bone?

Cartilage and bone are connective tissues that resist compression as well as tension. Both cartilage and bone consist of cells and abundant extracellular matrix.

What feature do cartilage and bone have in common?

Similarities between Bone and Cartilage Ø Both provide shape to body parts. Ø Both provide protection to vital organs. Ø Both are mesodermal in origin. Ø Both composed of specialized cells embedded in the matrix of fibrous proteins.
