Tissues - Epithelial & Connective

epithelial tissue function

protection, secretion, absorption, filtration, excretion, sensation

simple squamous epithelium location

alveoli, glomeruli, endothelium, serosa

simple cuboidal epithelium location

liver, thyroid, glands, bronchioles, kidney tubules

simple columnar epithelium location

GI tract, uterus, kidney, uterine tubes

pseudo stratified columnar epithelium location

nasal cavity, bronchi, male urethra

keratinized stratified squamous epilethium location

epidermis, palms, soles

nonkeratinized stratified squamous epithelium location

tongue, oral mucosa, esophagus, vagina

stratified cuboidal epithelium location

sweat glands, overian follicles, seminiferous tubules

urothelium / transitional epithelium location

ureter, bladder

connective tissue function

binding of organs, support, physical protection, immune protection, movement, storage, heat production, transport

arelor tissue location

under epithelia, in serous membranes, between muscle, passageways for nerves and blood vessels

reticular tissue location

lymph nodes, spleen, thymus, bone marrow

dense regular connective tissue location

tendons, ligaments

dense irregular connective tissue location

deeper layers of skin, capsules around organs

hyaline cartilage location

articular cartilage, costal cartilage, trachea, larynx, fetal skeleton

elastic cartilage location

external ear, epiglottis

fibrocartilage location

pubic symphysis, menisci, intervertebral discs

blood characteristics

erythrocytes, leukocytes, plasma, platelets

bone characteristics

calcium, phosphate, vascular, calcified lamellae, osteocytes in lacunae

cartilage characteristics

chondrocytes in lacunae, perichondrium, avascular

adipose characteristics

little matrix, pressed nuclei, triglycerides, adipocytes

areolar tissue characteristics

loose organized fibers, lot of blood vessels

reticular tissue characteristics

reticular fibers, fibroblasts, creates a framework

dense regular connective tissue characteristics

parallel collegen fibers, elastic fibers form wavy sheet

dense irregular connective tissue characteristics

randomly arranged collagen fibers, withstands stress

keratinzed stratified squamous epithelium characteristics

keratin protein, slows water loss, resists abrasion by microorganisms

nonkeratinzed stratified squamous epithelium characteristics

does not have keratin protein

stratified cuboidal epithelium characteristics

secretes sweat, produces sperm, produces ovarian hormones

urothelium / transitional epthium characteristics

filling of urinary tract, surface cells change when stretched

simple squamous epithelium characteristics

permits rapid diffusion and transport, secretes serous fluid

simple cuboidal epithelium, simple columnar epithelium, and pseudostratified columnar epithelium characteristics

absorption, secretion, mucus production, movement

secretion

product useful to the body

excretion

waste product

tight junctions

barrier, things can only go through cells not around

desmosomes

cell adhesion proteins, keep cells from being ripped apart, extend into cytoskeleton

gap junction

allows things to move from cell to cell, connexons, electrical signaling

hemidesmosomes

holds cell to basement membrane

endocrine

need blood supply, connecting cells die off

exocrine

duct, inner cells die off

connective tissue characteristics

fibers, ground substance, majority of tissue volume, determines specific functions
