QuestionAnswer
gel-like matrix with all three fiber types; cells: fibroblasts, macrophages, mast cells loose connective areolar
function: wraps and cushions organs; plays an important role in inflammation loose connective areolar
location: widely distributed under epithelia of the body; packages organs; surrounds capillaries loose connective areolar
same matrix as areolar, but very sparse; closely packed fat cells; the nuclei are pushed to the side because of the large fat droplets loose connective adipose
function: provides reserve fuel; insulates against heat loss; supports and protects organs loose connective adipose
location: under skin, around kidneys and eyeballs; within abdomen; in breasts loose connective adipose
network of reticular fibers in a typical loose ground substance; reticular cells lie on the network loose connective reticular
function: fibers form a soft internal skeleton that supports other cell types including white blood cells, mast cells, and macrophages loose connective reticular
location: lymphoid organs like the lymph nodes, bone marrow, and spleen loose connective reticular
primarily parallel collagen fibers, a few elastic fibers; major cell type is the fibroblast dense regular
function: attaches muscles/bones to other muscles/bones; withstands great stress when pulling force is applied in one direction dense regular
location: tendons, most ligaments such as the shoulder joint dense regular
regular connective tissue containing a high proportion of elastic fibers dense elastic
function: allows recoil of tissue following stretching; maintains the flow of blood through arteries dense elastic
location: walls of large arteries, within the walls of the bronchial tubes, within certain ligaments associated with the vertebral column dense elastic
primarily irregularly arranged collagen fibers; some elastic fibers; major cell type is the fibroblast dense irregular
function: able to withstand tension exerted in many directions; provides structural strength dense irregular
location: fibrous capsules of organs and of joints; dermis of the skin dense irregular
amporphous but firm matrix; collagen fibers form a subtle network; chondroblasts produce the matrix and when they mature they lie in lacunae hyaline cartilage
function: supports and reinforces; has resilient cushioning peroperties; resists compressive stress hyaline cartilage
location: forms most of the embryonic skeleton; covers the ends of long bones in the joint cavities; forms costal cartilages of the ribs; cartilages of the nose, trachea, and larynx hyaline cartilage
similar to hyaline cartilage but more elastic fibers in matrix; chondrocytes lie in lacunae elastic cartilage
function: maintains the shape of a structure while allowing great flexibility elastic cartilage
location: supports the external ear; epiglottis elastic cartilage
matrix ximilar to but less firm than that in hyaline cartilage; thick collagen fibers predominate fibrocartilage
function: tensile strength with the ability to absorb compressive shock fibrocartilage
location: intervetebral discs; pubic symphysis; discs of knee joint fibrocartilage
hard, calcified matrix containing many collagen fibers; osteocytes lie in lacunae; very well vascularized bones
supports and protects; provides levers for the muscles to act on; stores calcium and other minerals and fat; marrow inside is the site for blood cell formation bones
red and white cells in fluid matrix called plasma; contains lymphocytes and neutrophil blood
function: transport of respiratory gases, nutrients, wastes, and other substances blood
neurons are branching ells; cell processes that may be quite long extend from the nucleus-containing cell body; also contributing to nervous tissue are non irritable supporting cells nervous tissue
function: transmit electrical signals from sensory receptors and to effectors which control their activity nervous tissue
location: brain, spinal cord, and nerves nervous tissue
long, cylindrical, multinucleate cells; obvious striations skeletal muscle
function: voluntary movement; locomotion; manipulation of the environment; facial expression; voluntary control skeletal muscle
location: attached to bone skeletal muscle
branching, striated, generally uninucleate cells that interdigitate at specialized junctions cardiac muscle
function: as it contracts, it propels blood into the circulation; involuntary control cardiac muscle
location: walls of the heart cardiac muscle
spindle-shaped cells with central nuclei; no straitens; cells arranged closely to form sheets smooth muscle
function: propels substances or objects along internal passageways; involuntary control smooth muscle
location: mostly in the walls of hollow organs smooth muscle
