Tissue Types In The Body
Epithelial
(Functions) Tight junctions form a barrier Gap junctions allow rapid intracellular communication, channel proteins allow ions to pass through, responsible for coordinated contractions in the heart muscle. Desmosomes bind adjacent cells together allows for bending and twisting.
(found in) Epithelial tissue covers the outside of the body and internal organs and is catagorized based on the shape and layers of the cell.
(Looks like) closely packed cells that covers exposed surfaces, it has 2 sides One side is oriented towards the surface and may contain microvilli or cillia. The other side is connected to a basement membrane.
-
Simple Squamous
-
Found in air sacs of lungs, walls of capillaries
-
-
-
Simple Cuboidal
-
found in lining of kidney tubules ion and ph , thyroid gland, central canal of spinal cord(cerebrospinal fluid)
-
-
Stratified Columnar
-
Found in male urethra, ducts of salivary glands and cornea of eye
-
-
connective
(looks like) all types of connective tissue have 3 common characteristics: specialized cells, solid extracellular protein fibers, fluid extracellular ground substance all of these contribute to the matrix that surrounds the cells
-
all happens underneath the skin there are 4 different types of connective tissue: Adipose, Areolar, Bone, and Blood. Adipose is in abdominal membranes and around kidneys, heart, and joints provides energy storage and insulation.
-
Bone recovers from injuries in relatively short time stores minerals provides internal support and protects vital organs.
blood transports gasses, nutrients, waste, protects and heals wounds.
muscular
There are 3 major types of muscle tissue skeletal, smooth, and cardiac. Skeletal is found near the plasma membrane, Smooth lines the wall of blood vessels and certain organs where it serves to move substances, and cardica is found in the walls of the heart
-
Skeletal is long cylindrical cells that are striated with bands running perpendicular to the cell also is multinucleated.
Smooth is elongated cells with tapered ends that contain a single centrally located nucleus.
Cardiac is striated with a single centrally located nucleus and the muscle fibers branch out often
nervous
-
allows the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body
-
