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 are three components of bones?

Bones consist of living cells embedded in a mineralized organic matrix. This matrix consists of organic components, mainly type I collagen—”organic” referring to materials produced as a result of the human body—and inorganic components, primarily hydroxyapatite and other salts of calcium and phosphate.

What are the two types of bones?

There are two types of bone tissue: compact and spongy. The names imply that the two types differ in density, or how tightly the tissue is packed together.

What are the important organs in the skeletal system?

The skeletal system is imperative for movement as well. It also helps create the red blood cells that carry oxygen around your body, allowing you to make energy and stay alive. Today, we’re going to look at the four main organs of the skeletal system: bones, cartilage, ligaments, and tendons.

What are the two types of bone and what are their features?

Bones are made of two tissue types:Compact bone: also known as cortical bone, this hard-outer layer is strong and dense.Cancellous bone: also known as trabecular bone, this spongy inner layer network of trabeculae is lighter and less dense than cortical bone.

Which bone is the strongest bone in the body?

The femur bone is the longest and strongest bone in the body. Located in the thigh, it spans the hip and knee joints and helps maintain upright posture by supporting the skeleton.

What are four major functions of a bone an organ of the skeletal system?

The major functions of the bones are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and hematopoiesis. Together, the muscular system and skeletal system are known as the musculoskeletal system.

What is the basic structure of the skeletal system?

The skeletal system includes the bones of the skeleton and the cartilages, ligaments, and other connective tissue that stabilize or connect the bones. In addition to supporting the weight of the body, bones work together with muscles to maintain body position and to produce controlled, precise movements.

What are 6 functions of the skeletal system?

The human skeleton serves six major functions: support, movement, protection, production of blood cells, storage of ions, and endocrine regulation.

What is the longest bone in the body?

femurThe femur is one of the most researched bones in the human anatomy and forensic medicine. As the longest bone in the human body, it is well preserved in skeletal remains.

How do we classify bones?

Bones can be classified according to their shapes. Long bones, such as the femur, are longer than they are wide. Short bones, such as the carpals, are approximately equal in length, width, and thickness. Flat bones are thin, but are often curved, such as the ribs.

What are the components of the skeletal system?

What is the skeletal system? The skeletal system is your body’s central framework. It consists of bones and connective tissue, including cartilage, tendons, and ligaments. It’s also called the musculoskeletal system.

What are the 7 functions of the skeletal system?

Section Review. The major functions of the skeletal system are body support, facilitation of movement, protection of internal organs, storage of minerals and fat, and blood cell formation.

What are the two major parts of the skeletal system?

The adult human skeleton usually consists of 206 named bones. These bones can be grouped in two divisions: axial skeleton and appendicular skeleton. The 80 bones of the axial skeleton form the vertical axis of the body.
