Tissues
Tissue | About Tissue |
---|---|
Epithelial Tissue | Covers and lines the body Location: Outer layer of skin, lining of intestines, lining on respitory tract. |
Simple Squamous | Allows diffusion, not protection. Location: lining of kidney, gas exchange in lungs. |
Simple Cuboidal | Secretion and Absorption Location: kidney tubules, ducts of small glands. |
Simple Columnar | Secretion, absorption, some protection, movement of mucous Location – nonciliated: lining of digestive tract, Ciliated: uterine tubes, bronchi |
Psuedostratified columnar | Secretion, movement of mucous and sex cells, some protection Location :respiratory passages (trachea) and reproductive system tubes |
Stratified squamous | Protection of underlying tissue Location keratinized: skin - nonkeratinized: moist linings of mouth, esophagus, and vagina |
Stratified Cuboidal | Secretion Location: ducts of large glands such as sweat glands and mammary glands |
Stratified Columnar | Acts as transitional tissue between two types of tissues Location: lining of some ducts, parts of urethra |
Transitional epithelial | Allows bladder and urinary tract to stretch when filled with urine Location: urinary tract: ureter, bladder, urethra |
Connective Tissue | Binding and support, protection, insulation, transportation Location: In between other tissues |
Areolar | Binds organs together Location: beneath epithelial tissue; between muscles |
Adipose | Protection, insulation, fat storage Location: beneath skin, around organs |
Reticular | Immune system; produce and store white blood cells Location: lymph nodes, spleen, thymus, bone marrow |
Dense | Binds organs together Loaction: tendons, ligaments |
Hyline Cartalige | Support, provides surface for bones to move over Location: nose, ends of long bones, fetal skeleton |
Bone | Support, protection, helps in movement Location: Body |
Blood | Transportation of nutrients, oxygen, and carbon dioxide; fights infection |
Fibrocartalige | Flexable Location: Ear |
Elastic Cartalige | Absorbs shock, reduces friction Location: meniscus in knee, cartilage between vertebrae |
Musclear Tissue | Movement |
Skeletal Muscle | Voluntary movement Location: attached to long bones |
Smooth Muscle | Push object(s) through internal passage (digested food, urine, baby) constriction of blood vessels, pupils, etc… Involuntary control Location: walls of hollow organs such as digestive tract, etc… |
Cardiac Muscle | Contraction of heart, involuntary control Location: Heart |
Nervous Tissue | Conducts nerve impulses Location: brain, spinal cord, nerves |
Microvilli | Absorption, occurs more often and quicker Structure: Tiny finger like projections that increase the cells surface area |
Tight Junctions | prevents substances from passing through to other tissies, keeps chemicals in cells Structure: Leak proof sheet that bind cells together (zipper) |
Gap Juntions | allow communicaion= rapid exchange, cells exchange stuff Structure: hollow cylinders between cells that span the entire width of the membrane |
Desmosomes | prevents cells subjected to mechanical stress, from being pulled apart. Structure: anchoring juntions, button like with protein (thread) that binds cells together. |
Matrix | Ground substance of matrix is composed largely of water, adhesion protiens and large pdysacchande Connective have most matrix |
