Four Tissue Types Right Ans - 1. connective tissue
2. epithelial tissue
3. muscle tissue
4. nervous tissue

Epithelial Tissue Right Ans - tissue is typically avascular
uses a basement membrane to attach to the underlying tissue

Connective Tissue Right Ans - typically vascular (blood if a computed
tomography [CT])

Muscle Tissue Right Ans - is vascular

Cardiac Tissue Right Ans - subtype of muscle tissue and is vascular

Nervous Tissue Right Ans - Tissue that senses stimuli and transmits signals
found in the brain, spinal cord, and nerves

Epithelial Tissue is Right Ans - Lines all body cavities
Covers body surfaces
Forms glands
Has several subtypes

Connective Tissue is Right Ans - Underlies or supports the other three
basic tissues, both structurally and functionally.
Provides support and protection of organs and organ systems. Is the most
diverse tissue type.
Has several subtypes, such as blood and bone.

Muscle Tissue is Right Ans - Is made up of contractile cells and is

, Processes information.

Epithelial (2 surfaces types) Right Ans - Epithelial cells have an exposed
surface known as the apical surface.
Epithelial cells also have an attachment to the basal lamina, known as the
basal surface

Epithelial (nutrients and structure) Avascularity Right Ans - Epithelial
tissue is devoid of blood vessels.
It must obtain nutrients via diffusion or absorption across the epithelial
surface.
Epithelial tissue is dependent on the underlying connective tissue to supply its
needs for oxygen and nutrients

Epithelial Regeneration Right Ans - Damaged or lost epithelial cells at the
exposed surface are continually replaced through stem cell division.
The rate of regeneration is much higher in epithelial tissue in comparison to
other tissue types.

Glandular Epithelium Right Ans - Glandular epithelium provides secretions
onto epithelial surfaces and secretions into the interstitial fluid or blood

Squamous Epithelium Right Ans - Cells are thin and flat.
Cells are much wider than tall, resembling a fried egg.
The nucleus is highly flattened.

Cuboidal Epithelium Right Ans - Cells are square shaped.
Cells are of equal height and width.
Cells are box-like or look like squares.
The nucleus is spherical.

Columnar Epithelium Right Ans - Cells are tall, slender, and rectangular.
Cells are much taller than they are wide.
The nucleus is oval-shaped and elongated, generally located toward the base
of the cell.

Function of Glia Cells Right Ans - function of all glial cells is to support and
protect neurons. Glial cells are by definition not electrically excitable, so they
cannot send motor or sensory information
