Fibers

Collagen: tough; provides high tensile strength Elastic: long, thin fibers that allow for stretching Reticular: branches collagenous fibers that form delicate networks

Cardiac (Muscle)

Found in the walls of the heart

Blood (Connective)

functions in transport of respiratory gases, nutrients, and wastes

Ground Substance

interstitial (tissue) fluid; adhesion proteins: fibronectin and laminin proteoglycans: glycosaminoglycans (GAGs) Functions as molecular sieve through which nutrients diffuse between blood capillaries and cells

Elastic Cartilage (Connective)

allows flexibility; supports external ear (pinna); and the epiglottis (blocks food from going down the trachea)

Connective Tissue Proper Dense Regular

attaches muscle to bone (tendon) or to other muscles, and bone to bone (ligament); found in tendons, ligaments, and aponeuroses

Connective Tissue Proper Loose Areolar

contains all three connective tissue fibers; wraps and cushions organs and is widely distributed throughout the body

Connective Tissue Proper Loose Adipose

contains closely packed adipocytes; reserves food stores; insulates against heat loss, and supports and protects; found under skin, around kidneys, within abdomen, and in boobs

Cells

fibroblasts: connective tissue proper chondroblasts: cartilage osteoblasts: bone hematopoietic stem cells: blood White blood cells, plasma cells, macrophages, and mast cells

Stratified Squamous (Epithelia)

forms the external part of the skin's epidermis and linings of the esophagus, mouth, and vagina

Fibrocartilage Cartilage (Connective)

found in intevertebral discs, the pubic symphysis and in the discs of the knee joint

Skeletal (Muscle)

found in muscles that attach bones or skin

Stratified Columnar (Epithelia)

found in pharynx, male urethra, and lining some glandular ducts; also in transition areas between 2 other types of epithelia

Endocrine Glands (Epithelia)

found in secretions that include amino acids, proteins, glycoproteins, and steroids

Nervous Tissue

found in the brain, spinal cord, and peripheral nerves

Smooth (Muscle)

found in the walls of hollow organs (hollow tubes)

Connective Tissue

found throughout the body; most abundant and widely distributed in primary tissues

Transitional (Epithelia)

lines the urinary bladder, ureters, and part of the urethra

Connective Tissue Proper Loose Reticular

loose ground substance with this type of fibers; they lie in a fiber network; found in lymph nodes, bone marrow, and the spleen

Simple Cuboidal (Epithelia)

present in kidney tubules, ducts and secretory portions of small glands, and ovary surface

Pseudostratified Columnar (Epithelia)

present in male sperm-carrying ducts (nonciliated) and in the trachea (ciliated)

Simple Squamous (Epithelia)

provides a slick, friction-reducing lining in the lymphatic and cardiovascular system; present in the kidney glomeruli, lining of the heart, blood vessels, lymphatic vessels, and serosae

Connective Tissue Proper Dense Irregular

provides structural strength; found in the dermis, submucosa of the digestive tract, and fibrous organ capsules

Stratified Cuboidal (Epithelia)

rare in the body; found in some sweat and mammary glands (typically two cell layers thick)

Exocrine Glands (Epithelia)

secretes products onto body surfaces (skin) or in body cavities examples are mucus, oil, sweat, and salivary glands

Bone (Osseous Tissue) (Connective)

supports, protects, and provides levers for muscular action; stores calcium, minerals, and fat

Hyaline Cartilage (Connective)

supports, reinforces, cushions, and resists compression; forms the costal cartilage; found in embryonic skeleton, the end of long bones, nose, trachea, and larynx

Embryonic (Connective)

Mesenchyme; gel-like ground substance with fibers and star-shaped mesenchymal cells; gives rise to all other connective tissues; found in embryo

Simple Columnar (Epithelia)

Non-ciliated type line the digestive tract and gallbladder Ciliated type line the small bronchi, uterine tubes, and some regions in the uterus
