group of cells that have a common structure and function
tissue
4 major types of tissues in the human body
epithelial
connective
muscle
nerve
point of contact between plasma membranes of cells
cell junctions
3 types of cell junction
tight junction
anchoring junction
gap junction
tight junction
fluid tight cells
anchoring junction
hold cells to other cells or other structures
location of tight junction
stomach, small intestines
location of anchoring junction
outer layer of skin, muscles, gastrointestinal tract
location of gap junction
part of nervous system, cardiac muscles
functions of epithelial tissue
protection, diffusion, absorption, secretion
tissue with the fastest mitotic/replication rate
epithelial
mostly cells and very little extracellular fluid
-avascular
epithelial
tissues can be arranged in a single layer or multiple layers
epithelial
single layer of epithelial tissue called
simple
multiple layers of epithelial tissues are called
stratified
mixture of cell shapes in one layer of epithelial tissue is called
pseudostratified
cells can be varied(squamous, cuboidal, columnar) in which tissue
only in epithelial
thin flat cells
squamous
cells that are as tall as wide
cuboidal
cells that are taller than they are wide
columnar
cells that can change shape due to tension
transitional
referred to as “lining tissue” because it lines inside and outside of all structures in the body
epithelial
epithelial tissue firmly adheres to the connective tissue just beneath it by a membrane called a _______________.
basement membrane
function of simple squamous
diffusion
function of cuboidal or simple columnar
absorption and secretion
function of stratified squamous,cuboidal, or columnar
protection, absorption, and secretion
glands are considered ________________.
epithelial tissue
one cell or group of highly specialized cells that secrete substances into and through ducts to the surface of a structure/organ/tissue or secretes substances into the bloodstream
gland
secrete their substance into bloodstream
endocrine glands
examples of endocrine glands
thyroid, pituitary, adrenal, hypothalamus, pineal
secrete their substance into and through a duct to the surface of a structure/organs/tissue
exocrine glands
examples of exocrine glands
sebaceous, sudoriferous, ceruminous, salivary
functions of connective tissue
protection, gives body structure, energy storage, body temp homeostasis, binds organs together, carries oxygen, immune system
tissue with the fewest cell junctions
connective
most abundant tissue in body
connective
examples of connective tissue
bone, ligament, tendons, cartilage, adipose, blood
connective tissue that is vascular
bone, ligaments, tendons, adipose
connective tissue that is avascular
cartilage
connective tissue consists of 3 basic units
cells, ground substance, fibers
intracellular/extracellular fluid found between the cells of the tissue
matrix
3 types of fibers found within connective tissue
collagen, elastic, reticular
different classification of cells present in connective tissue
fixed cells
wandering cells
fixed cells-
always present in stable number
wandering cells-
appear in tissue temporarily
fixed cells in connective tissue
fibroblasts, mast cells
wandering cells in connective tissue
macrophages
functions of muscle tissue
contract to produce force for motion
most vascular tissue in body
muscle tissue
type of muscle fibers
skeletal, cardiac, smooth
when muscles decrease in size due to non-use or disease
muscle atrophy
when muscle fibers increase in size due to strenuous anaerobic use
muscle hypertrophy
muscle fibers that are under our conscious control to contract
voluntary muscles
muscle fibers that are not under our conscious control to contract
involuntary muscle fibers
production of heat as a result of muscle contraction and relaxation
themogenesis
alternating light and dark cross-making on some types of muscle tissue
striations
the shortening of a muscle fiber to produce force
muscle contractions
when a muscle fiber can no longer contract
muscle fatigue

cellular processes that receive nerve impulses from other neurons
dendrites
cellular process that relays nerve impulses from one neuron to another neuron or to a muscle or gland
axon
