Pitt Anatomy Lab Quiz 3 - cell types

simple columnar

single layer of column shaped cells with round nucleus, contains goblet cells

simple columnar - function

secretion of mucous, absorption

simple columnar - location

lines digestive tract and portions of the uterus and uterine tubes

simple cuboidal

single layer of cubed shaped cells, large and round with central nuclei

simple cuboidal - function

absorption, secretion, active transport

simple cuboidal - location

thyroid, ovaries, kidney duct

pseudostratified

single layer of cells with differing nuclei, nuclei located at different heights, all cells touch base membrane, not all touch apical surface, contain cilia

pseudostratified - function

goblet cells release mucous that coats passage ways

pseudostratified - location

respiratory tract, male urethra

simple squamous

single layer thick, flat or oval with a central nucleus

simple squamous - function

diffusion, secretion, filtration

simple squamous - location

capillaries, endothelium, alveoli

stratified squamous

multiple layers of cells with nuclei throughout

stratified squamous - function

protection against abrasion

stratified squamous - location

esophagus, anus, mouth, vagina, epidermis of skin

stratified cuboidal

many layers of cube cells

stratified cuboidal - function

protection, secretion

stratified cuboidal - location

sweat glands, ovary follicles, mammary glands

transitional

tissue changes shape, relaxed = cuboidal, stretched = squamous

transitional - function

allows stretching as it fills

transitional - location

bladder, urethra, ureters

stratified columnar

apical layer is composed of columnar cells, basal is cuboidal

stratified columnar - function

protection, secretion

stratified columnar - location

large ducts and some glands

transitional

what are the parts of the extracellular matrix (areolar) aka protein fibers

collagen, reticular fibers, elastin fibers

collagen

rope-like and strong but inflexible

reticular fibers

tiny collagen fibers that act like web between cells

elastin fibers

can be stretched and returned to its original shape

areolar (ECM)

matrix contains all three fibers collagen, elastic, reticular held loosely together

areolar (ECM) - function

anchors skin to underlying tissues, anchors tissues together, surrounds capillaries and tissue, around organs

areolar (ECM) - location

everywhere in body

adipose

fat cells, a drop of fat is put in each cell and this pushes the nucleus to the edge of the cell, nucleus is highly vascular

adipose - function

cushioning, insulation, energy storage

adipose - location

center of femur, under skin, around kidney, eye balls

dense regular

unidirectional, nuclei are aligned parallel, densely packed fibers

dense regular - function

attaches muscles to bones (tendons), attaches bones to bones (ligaments)

dense regular - location

tendons, ligaments, aponeuroses

dense irregular

random assignment, multiple directions

dense irregular - function

strong in all directions

dense irregular - location

dermis of skin, capsules around organs and joints

hyaline

what tissue is depicted in the image

fibrocartilage

hyaline cartilage

articular surfaces and joints, has lacuna and chondrocyte

elastic cartilage

larynx, nose, ear, very flexible, has lacuna and chondrocyte

fibrocartilage

absorbs shock, intervertebral disks, has lacuna and chondrocyte

what tissue is depicted in the image

bone

what tissue is depicted in the image

blood

bone

consists of mineralized ECM, lacunae is holes in the matrix where osteocytes reside

blood cells

suspended in fluid matrix, classified as connective tissue because it derives from mesenchyme

nervous tissue - function

specialized to carry electrical signals called action potentials

nervous tissue

dendrites, cell body, axon

nervous tissue - location

brain, spinal cord, peripheral nerves

what tissue is depicted in the image

nervous tissue

skeletal muscle tissue

striated, voluntary, multinucleated

cardiac muscle tissue

striated, involuntary, uninucleated

smooth muscle tissue

nonstriated, involuntary, uninucleated
