Term
Connective tissue
Definition
Tissue that connects and supports other tissues
Term
What characterizes connective tissue?
Definition
Relatively few cells suspended in an extracellular matrix of fibers, which may be embedded in a liquid, jellylike or solid substance.
Term
What are the three types of connective tissue?
Definition
Collagenous fibers, elastic fibers, and reticular fibers
Term
Collagen fibers
Definition
Made of collagen and have nonelastic strenth
Term
Elastic fibers
Definition
Made of the protein elastin, and can stretch and provide resilience
Term
Reticular fibers
Definition
Composed of collagen, form a tightly woven connection with adjacent tissues, and are branched and thin
Term
Loose connective tissue
Definition
attaches epithelia to underlying tissues and holds organs in place
Term
Loose connective tissue is made of:
Definition
loosely woven fibers
Term
The most common types of cells enmeshed in loose connective tissue are?
Definition
Fibroblasts
Term
Fibroblasts secrete _____
Definition
the protein of the extracellular fibers, and macrophages
Term
Adipose tissue
Definition
A special form of loose connective tissue
Term
Funtion of adipose tissue
Definition
It pads and insulates the body and stores fat. All contain a fat droplet.
Term
A tissue with a dense arrangement of parallel collagenous fibers
Definition
Fibrous connective tissue
Term
Fibrous connective tissue is found in _____ and _____
Definition
Tendons, which attach muscles to bones, and in ligaments, which join bones together at joints
Term
Cartilage
Definition
Composed of collagenous fibers embedded in a rubbery substance called chondriotin sulfate, both secreted by chondrocytes.
Term
______ is a strong but somewhat flexible support material, making up the skeleton of vertebrate embryos.
Definition
Catrilage
Term
Bone
Definition
Mineralized connective tissue
Term
Bone is formed by ____
Definition
Osteoblasts, that deposit a matrix of collagen and calcium, magnesium, and phosphate ions, which hardens into hydroxyapatite.
Term
Osteons
Definition
Consist of concentric layers of matrix around a central canal containing blood vessels and nerves
Term
Blood
Definition
Connective tissue that has a liquid extracellular matrix called plasma.
Term
Erythrocytes
Definition
Red blood cells that carry oxygen
Term
Leukocytes
Definition
White blood cells that function in defense
