BIOL L tissues

simple squamous

single layer of flattened cells

epithelial simple squamous

provide for rapid diffusion of gasses and dissolved solutes across membranes

simple squamous

located in the alveoli of the lungs, the endothelial cells of capillaries, glomeruli of kidneys

simple cuboidal

single layer of cube-shaped cells

simple cuboidal

secretes and absorbs, sometimes ciliated-driven movement of materials

simple cuboidal

lines the lumens of small secretory ducts, kidney tubules; portions of bronchioles; reproductive ducts, and ureters

simple columnar

secretes and absorbs, sometimes ciliated-driven movement of materials; often possess microvilli to increase surface area of apical membrane

simple columnar

lines the intestinal tract and the lumens of some secretory ducts, lines bronchi and uterine tubes

stratified squamous

multiple layers of flattened cells

stratified squamous

protection from abrasive forces

stratified squamous

located in keratinized type forms the upper portion of the skin; non-keratinized type forms the wet surfaces of the esophagus, mouth, vagina, and rectum

stratified cuboidal

multiple layers of square cells

stratified cuboidal

protection; secretion of mucus

stratified cuboidal

located in sweat glands, mammary glands, and salivary glands

stratified columnar

multiple layers of tall cells

stratified columnar

protection; secretion of mucus

stratified columnar

rare in the body; some found in male urethra and ducts of large glands

Cell

the smallest structural and functional unit of life in an organism consisting of many working components with the ultimate purpose of maintaining homeostasis

homeostasis

the process by which an internal environment is kept constant despite a constantly changing external environment

organelles

in order to maintain homeostasis, cells contain different types of ? that serve different functions

false

all cells are created equal or have the same type and number of organelles

mitosis

a process how most human cells reproduce through in which the cell cleaved in two after key components have been duplicated

interphase

initially, cells begin in ? during which time the cell grows and DNA is duplicated

four phases of mitosis are:

prophase, metaphase, anaphase, telophase

prophase

DNA condenses into 23 distinct pairs of chromosomes, nuclear membrane disperses, each pair is joined together by a protein bridge called a centromere

centromere

protein bridge that joins together each pair in prophase

metaphase

chromosomes align themselves midway between poles

anaphase

chromosome pairs separate and move toward opposite poles

telophase

Nuclear membrane begins to form and chromosomes decondense into chromatin, and cell membrane begins to "pinch" eventually cleaving in two (known as cytokinesis)

histology

study of tissues

squamous

flat; function = diffusion

cuboidal

cubed; function = secretion or absorption

columnar

tall; function = secretion or absorption; if ciliated, then to also help with movement of materials

simple

one layer

stratified

numerous layers

epithelial tissue

very cellular, highly mitotic, avascular (no blood vessels), polar, regenerative

epithelial tissue

lines body cavities and parts of the body exposed to the outside world

simple squamous

simple cuboidal

stratified squamous

simple columnar

connective tissue proper loose

lymphocytes, mast cells, macrophages, fibroblasts, leukocyte, adipocytes

loose areolar connective tissue

fibroblast; collagen, reticular, and elastic

loose areolar connective tissue

function = wraps and cushions organs; holds and conveys tissue fluid during inflammation

loose areolar connective tissue

location: under epithelia, packages organs, surrounds capillaries

loose adipose connective tissue

adipocytes; function = energy storage; soft padding between moving organs and joints; heat conservation

loose adipose connective tissue

Location: Surrounds organs/joints; dermis of the skin; female breast

loose reticular connective tissue

function = fibers create a skeleton like framework to support other cell types

loose reticular connective tissue

Location: Spleen, lymph nodes, bone marrow, liver

dense connective tissue proper

fibroblasts secrete collagen

dense regular connective tissue

Function: Forms tendons and ligaments; withstands great tensile strength in one direction

dense regular connective tissue

Location: Tendons, ligaments, aponeuroses

dense irregular connective tissue

Function: Withstands tensile strength from many directions

dense irregular connective tissue

Location: Dermis of skin, joint capsules, vessels

cartilage

has chondrocytes inside lacunae

hyaline cartilage tissue

Function: Support and protection

connective cartilage hyaline tissue

Location: Trachea, larynx, costal cartilage, nose, ends of long bones

elastic cartilage tissue

Function: Provides support with flexibility

elastic cartilage tissue

location: external ear and epiglottis

fibrocartilage tissue

Function: Absorb compressive shock

fibrocartilage tissue

location: intervertebral discs, pubic symphysis, meniscus of knee joint

bone

has osteocytes

blood

what tissue has cell types such as: erythrocytes, leukocytes, thrombocytes

bone

Function: support for the body; protection; storage of minerals

bone

location: skelton

blood

function: transport of nutrients and waste products

blood

location: within blood vessels

skeletal muscle tissue (voluntary)

function: move bones and produce heat

cardiac muscle tissue (involuntary)

function: synchronized contraction of heat to push blood throughout the body

smooth muscle tissue

function: contractions push material through a tract and adjusts diameter of blood vessels

nervous tissue

functions to transmit and process information throughout the body and can be divided into two groups based on functionality: Neurons: provide primary electrical pathways and Neuroglia: supporting cells that aid neurons

Neurons

provide primary electrical pathways

Neuroglia

supporting cells that aid neurons
