Anatomy and Phyis Tissues Test Review

Epithelial Tissue

Found throughout body, rapidly divides, material being moved, great for protection, avascular, cells tend to be packed tightly together

Simple

One layer

Stratified

Multiple Layers

Squamous

Flat

Columnar

Tall

Cubodal

Cube

Simple Squamous

One Layer, Flat Cells

Simple Cuboidal

One Layer, Square

Simple/ Pseudo Columnar

One Layer, Rectangle

Stratified Squamous

Many Layers, Flat

simple squamous

locat

Avioli of lungs, blood capillaries/blood vessels

Funct

Facilitate gas exchange (co2 o2)

regulates fluid movement between blood and tissue

simple cuboidal

locat

Kidney tubules, ducts of glands, covering ovaries

funct

Secretion (release substances), Absorption (Taking in substances)

simple/pseudo columnar

locat

Stomach + GL tract, respitory tracts (pseudostratified)

funct

secretion (enzymes), absorption (nutrients) — Makes Mucus!

stratified squamous

locat

esophagus, mouth, epidermis

funct

protection-barrier to pathogens, secretion of karatin (forms tough outer layer)

Transitional

Flat and Square, multiple layers, unorganized

transitional

locat

lines parts of urinary system (Bladder + uterer + urethra)

funct

stretches

Connective Tissue

Most abundant tissue in body

binds structures together

support, insulation, protection

can contain a network of fibers

Fibroblasts

Cells that make various fibers (protein)

Collagen Fibers

thick and strong

Elastic Fibers

Thin and very stretchy

reticular fibers

thin and springy

Areolar LOOSE

location: between muscles, beneath skin, beneath most epithelial layers

function: binding organs together

looks: “spider webby” (different thickness of lines)

Reticular DENSE IRREGULAR

location: major portion of skin (dermis (2nd) layer)

function: strength/flexibility, resistance from stretching

looks: “cracky”, dark purple, tadpoles, no pattern

Adipose LOOSE

location: deepest layer of skin

function: store lipids, look empty inside bc lipids dont stain well -insulation -shock absorption

looks: Big empty circles, bubbles

Dense Fibrous REGULAR

location: tendons and ligaments

function: bind bone to bone (tendon), bind bone to muscle (ligament)

Highland (Dense)

location: covers the ends of joints, nose & respitory passages (trachea + larynx)

function: support - joints/ respiratory protection (glassy appearences/most abundant)

Elastic (Dense)

location: pinna and spiglottis

function: support, yet stretchy

looks like: irregular, tightly packed, no pattern

Fibrocartilage (dense)

location: main component of intervertebral discs, inbetween vertebrae

function: shock absorption

Blood

location: in blood vessels

function: supplies cells w nutrients, oxygen, takes waste, fights infection

looks like: lots of red circles, white blood cells, look irregular

bone

location: makes up bones (skeleton)

function: support/protection

looks like: circular pattern, dark circle in middle

Smooth muscle tissue

INVOULENTARY

• spindles that flow together (neuclei in cells)

• lacks organized parallel structure

location: makes up hallow organs (stomach, intestines, esphogas, ect.)

Cardiac muscle Tissue

INVOULENTARY

• intercalacted discs (not straight/ branching)

• striations (organized/ structured tissue, tighly packed)

location : found in heart

Skeletal muscle tissue

VOULENTARY

• striations

location: muscle that attaches to bones

Nervous tissue

location: brain, spinal cord+ nerves of body

function: receives stimuli, transmits electrical signal, coordinate controlled bodily functions
