-
name the four types of epithelial tissues
- 1: simple cuboidal epithelium
- 2: simple columnar epithelium
- 3: stratified squamous epithelium
- 4:pseudostratified ciliated columnar epithelium
-
this type of tissue has a hollow space (lines body cavities)
name the tissue and name a place in the body it can be found
- simple cuboidal epithelium
- kidney, ovary, ducts of glands
-
this type of tissue contains goblet cells which lubricates and protects the digestive trace
simple columnar epithelium
-
this type of tissue is the outer (dermis) layer of skin and is found at wet surfaces of the body (mouth, vagina, etc)
stratified ciliated columnar epithelium
-
this tissue contains goblet cell and is the only tissue to have cilia
pseudostratified ciliated columnar epithelium
-
these type of tissues connect, bind, support, and protect
connective tissues
-
this type of tissue contains elastin fibers and collagen fibers
loose connective
-
these are stringy and stretchy, rubberband like material that holds skin to musculature in loose connective tissues
elastin fibers
-
flexible but strong material in connective tissues
collagen fibers
-
fat tissue-padding around the kidneys, heart and between skin and musculature
adipose
-
this tissue contains a smattering of cells, matrix, collagen fibers and are found in tendons and ligaments
dense fibrous connective
-
this tissue contains a chondrocyte that lives in its own lacunae
cartilage
-
a chondrocyte lives in a
lacunae
-
where are cartilage tissues found in the body
ears, nose, knee, larynx, ends of bones
-
cells called osteocyts are found in what tissue?
bone
-
an osteocyte lives in a
lacunae
-
the large blood vessel that allow the blood to flow thru the bone tissue is called
the haversion canal
-
what are the cannals that connect the lacunae to the haversion canal
canaliculi
-
what is the matrix of blood
plasma
-
non-living extracellular junk is called
matrix
-
what types of cells are contained in blood
white blood cells and red blood cells
-
smaller, more numerous cells in blood
red blood cells
-
larger cells, but fewer in number contained in blood
white blood cells
