Simple Squamous Epethelia

Simple Squamous Epethelia

-single layer/flat

-location: alveoli/mesothelium

-function: secretion, Diffusion, filtration

Simple Cuboidal Epithelium

-single layer/cubed

-location: kidney tubules/glands

-function: absorption/secretion

Simple Columnar Epithelium

-single layer/tall cells

-location: stomach lining/uterine

-function: secretion absorption

Stratified Squamous Epithelium

-multilayered/flat

-location: skin, mouth, vagina

-function: protection from abrasion

Transitional Epithelium

Change shape/multilayered

Location: urinalysis bladder

Function: permitting distention

Psuedostratisfied Epethelium

Illusion of multilayered

Location: nasal, trachea, bronchial

Function: secretion of mucus

Skeletal Muscle

Attached to skin and bone

Movement/heat

Cardiac Muscle

Wall of heart

Movement of blood throughout body

Intercalated discs

Smooth muscle

Walls of arteries

Control blood flow

Nervous Tissue

Neurons: send signals

Nueroglia: support neurons

Areolar Connective

Collagen, elastin, reticular Semi fluidBeneath epethelia Strength/nutrient absorption

Adipose Connective

Adipocytes Yellow bone marrow Thermal regulation/ endocrine function

Dense regular connective

Parallel bundles of collagen Tendons/ligaments Attachment to structures

Dense irregular Connective

CollagenHeart valves Resist pulling in different directions

Hyaline Cartilage Connective

GlossyChondrocytes Embryonic skeleton Smooth surface for joints

Fibrocartilage

Thick collagen fibersMeniscus of knee Support joint structures

Tonicity

Effect if solution if the shape of a cell

Hypertonic

Water flows out of the cell (crenation)

Isotonic

Not net change

Hypotonic

Water flows into the cell (hemolysis)

Basal Cell Carcinoma (BBC)

Low risk but very common Damage of DNA from UV lightOpen sores, red patches, scarsSkin exam, biopsySurgery, curvettage, Cryo, Moh’s, Medication Moh’s 98% effective: removes layer by layer (more skin preserved)Use sunscreen!
