What is the tough covering of the bone?

What is the tough covering of the bone?

The tough, thin outer membrane covering the bones is called the periosteum. Beneath the hard outer shell of the periosteum are tunnels and canals through which blood and lymphatic vessels run to carry nourishment for the bone. Muscles, ligaments, and tendons may attach to the periosteum.

What is a tough flexible connective tissue?

The tough, flexible strand of connective tissue. that holds bones together is a ligament. Ligaments. allow movement, and are found at the end of. bones.

What is the name of the tough flexible protein that makes bones?

Collagen is a protein that provides a soft framework, and calcium phosphate is a mineral that adds strength and hardens the framework. This combination of collagen and calcium makes bone strong and flexible enough to withstand stress.

What is the tough and flexible material that covers the ends where bones meet?

Ligaments. Strong ligaments (tough, elastic bands of connective tissue) surround the joint to give support and limit the joint’s movement. Ligaments connect bones together.

What is the periosteum?

The periosteum, endosteum and perichondrium are all layers of tissue in and around your bones. The periosteum is the sheath outside your bones that supplies them with blood, nerves and the cells that help them grow and heal. The endosteum is a membrane that lines the center of your bones that contain bone marrow.

What is a cartilage?

Cartilage a strong and smooth substance made up of “chondrocytes,” or specialized cartilage cells, that produce a matrix of collagen, proteoglycans (a special type of protein) and other non-collagenous proteins. These materials help cartilage attract water and give it its shape and specific properties.

What is the tough fibrous material that connects bone to bone?

ligament, tough fibrous band of connective tissue that serves to support the internal organs and hold bones together in proper articulation at the joints.

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 gives bones flexibility?

Collagen is what gives bones flexibility. Collagen is a protein fiber that is located throughout the body.

What connective tissue covers all bones?

The periosteum is a thin layer of connective tissue that covers the outer surface of a bone in all places except at joints (which are protected by articular cartilage).

What are the layers of a bone?

Bones are composed of two layers: a tough outer layer and a spongy inner layer. The outer layer, known as cortical or compact bone, is strong and dense. The inner layer, known as trabecular or cancellous bone, features a light network of connective tissue.

What is a tendon?

A tendon is a fibrous connective tissue that attaches muscle to bone. Tendons may also attach muscles to structures such as the eyeball. A tendon serves to move the bone or structure.
