BIO 201 Tissues
Stratified Squamous Epithelial
Location: (Keratinized): epidermis; (Non-Keratinized): tongue, vagina, anal canal, esophagus Function: resist abrasion, keep out pathogens, minimize water loss (keratinized)
Neuron
Location: Central and Peripheral Nervous Systems Function: transmit impulses
Elastic Cartilage, Connective
Location: External EAR, epiglotis Function: flexible, elastic support, maintain shape **surrounded by perichondrium (dense irregular tissue) --weblike mesh around lacuna
Cardiac Muscle
Location: Heart --intercalated disks-- Function: pumping of blood --mono-nucleate; striated; involuntary
Skeletal Muscle
Location: attached to bones, tonque, esophogas, lips, eyelids, urethra, anus, etc. Function: locomotion, expression, posture, speech, breathing --multinucleate; striated; voluntary
Transitional Epithelial
Location: bladder, part of urethra, umbilical cord (callantoic duct) Function: stretch to allow filling of urinary tract
Blood,Connective
Location: blood vessels Function: transport gases and nutrients as well as waste and signals and heat Erythocytes--RBC, no nuceli; transport gases Leukocytes--WBC, fight infection
Hyaline Cartilage, Connective
Location: costal cartilage, c-rings in trachea and bronchi, precursor to fetal bone, ends of long bones, NOSE Function: ease joint movement, hold airways open, support and cushion **surrounded by perichondrium (dense irregular tissue)
Irregular, Dense Connective
Location: deep in dermis, encapsulate organs, fibrous sheaths around bone and cartilage Function: durability (hard to tear), withstand space from unpredictable directions (multidirectional)
Smooth Muscle
Location: iris, skin, ureital and anal sphincters, digestive tract walls/ esophagus Function: swallowing, stomach and intestinal contractions, blood pressure, puppillary diamter, expulsion of urine and feces --fusiform cell shape; not striated; involuntary; mono-nucleate
Simple Columnar Epithelial
Location: lining of large intestine/diegstive track (unciliated); unterine tubes (ciliated) Function: secrete and move mucous, absorption and secretion, move oocyte and sperm
Reticular, Loose Connective
Location: lymphoid organs, nodes, spleen Function: supports other cell types **fibers in loose ground substane**
Fibrocartilage, Connective
Location: pubic symphysis, intervetebral disks, MENISCI Function: resist compression, absorb shock, transitional tissue at bone-tendon junction **no perichondrium --parallel collagen fibers
Pseudostratified Columnar Epithelial
Location: respiratory tract--nasal cavity to bronchi, male urethra Function: secretion and propelling of mucous
SImple Cuboidal Epithelial
Location: salivatory and mammary glands, kidney tubules, bronchioles Function: absorption and secretion
Bone, Connective
Location: skeleton Function: support, movement Central Canal, canaliculi (spaces between lamella), lacuna (nucelus-looking spots in lamella), Lamella (rings)
Stratified Cuboidal Epithelial
Location: sweat glands-ducts, ovary follicles, seminiferous tubules in testes Function: sweat secretion, ovarian hormone secretion, produce sperm
Regular, Dense Connective
Location: tendons and ligaments Function: bind bones to bones/ to muscles, resist stretch **parallel bands; not very vascular**
Areolar, Loose Connective
Location: under epithelium around blood vessels Function: wraps and cushions organs, connects epithelial and underlying tissues **gel-like matrix of different fibers**
Adipose, Loose Connective
Location: under skin, in abdomen, in breasts, around kidneys and eyeballs Function: metabolic fuel storage, thermal insulation, organ support and protection
Simple Squamous Epithelial
Location: veins, aretioles, alveoli, glomerular capsules of kidneys Function: rapid diffusion/osmosis
Connective Tissue
cells dispersed in a lot of ECM anchor, cushion, support body; most durable type
Nervous Tissue
generate and transmit electrochemical impulses; regulate and control body functions; sense environmntal stimuli
Muscle Tissue
major function is to contract; bodily movement, pump blood, flush urine out of body; express and emote
Epithelial Tissue
tightly packed cover body surfaces, line cavities, gladular tissues; absorb, secrete, and filter; secretes hormones; lie on connective tissue and basment membrane
