main functions of connective tissue
|
1.) storing energy (fat cells)
2.) transporting materials (blood) 3.) providing structure (bone) |
there are three of them (S.T.P)
|
|
location of areolar
|
between layers of skin
|
|
|
location of adipose
|
body fat
|
|
|
How is epithelial tissue classified?
|
by shape
|
|
|
purpose of connective tissue
|
binds and supports body parts
|
|
|
How is connective tissue classified?
|
by cell types and matrix
|
|
|
purpose of muscle tissue
|
moves the body and parts
|
|
|
How is muscle tissue classified?
|
by function
|
|
|
purpose of nervous tissue
|
receives stimuli and conducts impulses
|
|
|
location of hyaline
|
nose, ends of long bones
|
|
|
location of elastic
|
outer ear
|
|
|
fibrocartilage
|
between vertebrae
|
|
|
locations of skeletal muscle tissue
|
skeletal muscles (abs, biceps, etc.)
|
|
|
satellite cells
|
special stem cells that are produced by skeletal muscle tissue; they mature into muscle fibers, allowing some degree of repair after muscle injury
|
|
|
location of skeletal muscle tissue cell nucleus
|
typically just inside the cell membrane (skeletal muscle tissue cells are multinucleate; can have as many as several hundred)
|
|
|
intercalated discs
|
regions where cardiocytes connect with one another; desmosomes or gap junctions that allow for the passage of ions between cells (helps coordinate contractions)
|
|
|
pacemaker cells
|
establishes a regular rate of contractions/ heart beat
|
|
|
cardiocyte nucleus
|
typically have a singular central nucleus (may have more
|
|
|
smooth muscle nucleus
|
cells always have a single, oval shaped nucleus
|
|
|
locations of smooth muscle tissue
|
walls of blood vessels; surrounding respiratory, circulatory, digestive and reproductive tracts
|
|
|
peristalsis
|
the involuntary movement of smooth muscle tissue
|
|
|
transmembrane potential
|
differences in ion concentration between the cell and its surrounding environment
|
|
|
Where is 98% of the body's nervous tissue?
|
the brain and spinal cord (other 2% in peripheral nervous system)
|
|
|
the two basic types of nervous tissue cells
|
neurons and neuoglis
|
|
|
dendrites
|
numerous projections from the cell body (neurons); receives electrical impulses from other neurons
|
|
|
axon
|
a single long (sometimes over a meter), slender extension that conducts the signals that are received by dendrites on neighboring neurons; also called nerve fibers
|
|
|
functions of neuroglia
|
1.) support and repair neural tissue
2.) supply nutrients |
|
|
location of epithelial tissue (general)
|
covers body surfaces and lines body cavities
|
|
|
epithelia
|
one of the two main types of epithelial tissue; layers of cells that cover internal or external surfaces
|
|
|
location of epithelial tissue (general)
|
covers body surfaces and lines body cavities
|
|
|
glands (epithelial)
|
one of the two main types of epithelial tissue; specialized cells that produce fluid secretions
|
|
|
How are the cells in epithelial tissue bound together
|
by cell junctions (communications); unlike connective tissue which is separated by the matrix
|
|
|
main function of epithelial tissue
|
offers protection against environmental hazards and physical stresses
|
|
|
location of simple squamous
|
lining of heart and lungs
|
|
|
locations of stratified squamous
|
skin, beginning and end of digestive tract
|
|
|
locations of simple cuboidal
|
glands and kidneys
|
|
|
location of stratified cuboidal
|
(rare)
sweat glands |
|
|
locations of simple columnar
|
lining of stomach and intestines; kidneys
|
|
|
locations of stratified columnar
|
(rare)
parts of respiratory tract and some glands |
|
|
locations of pseudostratified columnar
|
usually ciliated; respiratory tract and lungs
|
|
|
endocrine glands
|
produce and release hormones into the body
(thyroid and pituitary glands) |
|
|
exocrine glands
|
release secretions from the body
(sweat glands, tear ducts, and mammary glands) |
|
|
tight junctions (not location)
|
proteins on adjacent cells join to form an impermeable barrier between the cells' plasma membrane
|
|
|
location of tight junction
|
digestive tract
|
|
|
gap junctions (not location)
|
channels between cells allow molecules to pass between them
|
|
|
location of gap junctions
|
muscles
|
|
|
desmosomes (w/ location)
|
durable interconnections between cells that allow for stretching
(the skin) |
|
