It is part of the skin dermis area and in the joint capsules of the limbs. The main fibers that form this tissue are elastic in nature. These fibers allow the tissues to recoil after stretching. This is especially seen in the arterial blood vessels and walls of the bronchial tubes. This is a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the elbow, the knee, the ankle, the bronchial tubes, and the intervertebral discs.
Cartilage is composed of specialized cells called chondroblasts and, unlike other connective tissues, cartilage does not contain blood vessels. Cartilage is classified in three types: 1 elastic cartilage, 2 hyaline cartilage, and 3 fibrocartilage, which differ in the relative amounts of these three main components.
This is similar to hyaline cartilage but is more elastic in nature. Its function is to maintain the shape of the structure while allowing flexibility. It is found in the external ear known as an auricle and in the epiglottis. This is is the most abundant of all cartilage in the body. Its matrix appears transparent or glassy when viewed under a microscope. It provides strong support while providing pads for shock absorption.
It is a major part of the embryonic skeleton, the costal cartilages of the ribs, and the cartilage of the nose, trachea, and larynx. This is a blend of hyaline cartilage and dense regular connective tissue. Because it is compressible and resists tension well, fibrocartilage is found where strong support and the ability to withstand heavy pressure are required.
It is found in the intervertebral discs of the bony vertebrae and knee meniscus. Bone tissue is also called the osseous tissue. The osseous tissue is relatively hard and lightweight in nature. It is mostly formed of calcium phosphate in the chemical arrangement termed calcium hydroxyapatite, which gives bones their rigidity. It has relatively high compressive strength, but poor tensile strength, and very low shear stress strength.
The hard outer layer of bones is composed of compact bone tissue, so-called due to its minimal gaps and spaces. Filling the interior of the bone is the trabecular bone tissue an open cell porous network also called cancellous or spongy bone , which is composed of a network of rod and plate-like elements that make the overall organ lighter and allow room for blood vessels and marrow.
This is considered a specialized form of connective tissue. Blood is a bodily fluid in animals that delivers necessary substances, such as nutrients and oxygen, to the cells and transports metabolic waste products away from those same cells. It is an atypical connective tissue since it does not bind, connect, or network with any body cells. It is made up of blood cells and is surrounded by a nonliving fluid called plasma.
Learning Objectives Describe the diverse types of connective tissue. Key Points The lymphatic system is a part of the circulatory system, comprising a network of conduits called lymphatic vessels that carry a clear fluid called lymph unidirectionally towards the heart. Blood is considered a specialized form of connective tissue. In vertebrates, it is composed of blood cells suspended in a liquid called blood plasma. The primary tissue of bone, osseous tissue, is a relatively hard and lightweight composite material, formed mostly of calcium phosphate in the chemical arrangement termed calcium hydroxylapatite.
Adipose tissue or body fat is loose connective tissue composed of adipocytes. Cartilage is a flexible connective tissue found in many areas in the bodies of humans and other animals, including the joints between bones, the rib cage, the ear, the nose, the elbow, the knee, the ankle, the bronchial tubes, and the intervertebral discs.
In humans, adipose tissue is located beneath the skin subcutaneous fat , around internal organs visceral fat , in bone marrow yellow bone marrow , and in breast tissue.
Key Terms cartilage : A type of dense, non-vascular connective tissue, usually found at the end of joints, the rib cage, the ear, the nose, in the throat, and between intervertebral disks. In vertebrates, it is colored red by hemoglobin, is conveyed by arteries and veins, is pumped by the heart, and is usually generated in bone marrow.
Connective tissue is divided into four main categories: Connective proper Cartilage Bone Blood Connective tissue proper has two subclasses: loose and dense. Areolar Connective Tissue These tissues are widely distributed and serve as a universal packing material between other tissues. This is especially seen in the arterial blood vessels and walls of the bronchial tubes.

Key Takeaways Key Points Connective tissue is the most abundant and widely distributed of the primary tissues. Connective tissue has three main components: cells, fibers, and ground substance.
Connective tissue is classified into two subtypes: soft and specialized connective tissue. Major functions of connective tissue include: 1 binding and supporting, 2 protecting, 3 insulating, 4 storing reserve fuel, and 5 transporting substances within the body.
Connective tissues can have various levels of vascularity. Cartilage is avascular, while dense connective tissue is poorly vascularized. Others, such as bone, are richly supplied with blood vessels. Key Terms extracellular matrix : Cells of the connective tissue are suspended in a non-cellular matrix that provides structural and biochemical support to the surrounding cells. Types of Connective Tissue Connective tissues encompass a diverse array of tissue types that are involved in binding and supporting body structure and tissues.
