Exam 1 Flash Cards
- The primary tissue type that covers most surfaces internally and externally
Epithelial tissue
- An epithelial tissue function of skin and mucous membranes
protection from irritants
- A primary function of epithelial tissue lining the small intestines
absorption of nutrients
- A primary function of epithelial tissue found in the glomerulus of kidneys
filtration of blood plasma
- An epithelial tissue function demonstrated by glands
secretion of enzymes, hormones, and fluids
- Epithelial tissue structure of one layer of cells
simple epithelium
- Epithelial tissue structure with more than one layer of cells
stratified epithelium
- Falsely stratified structure of epithelial tissue is called
pseudostratified epithelium
- Flat or disc like shape of epithelial cells
Squamous epithelium
Square like shape of epithelial cells
cuboidal epithelium
Tall shape of epithelial cells
columnar epithelium
Epithelial tissue structures that move material
cilia
- Epithelial cells that may appear squamous at one time and then cuboidal at another time are referred to as
transitional epithelium
Epithelial tissue structures that increase surface area
microvilli
Cells that may be associated with epithelial tissue that secrete mucus
goblet cells
Function of non-keratinized stratified squamous epithelium
protection from abrasion, moisture loss, and irritants
Location of simple columnar with microvilli epithelium
stomach, small intestine, and large intestine, as well as the gall bladder and Fallopian tubes, and uterus in the female reproductive system
Location of pseudostratified ciliated columnar epithelium
Respiratory tract and nasal cavity
Location of stratified squamous keratinized epithelium
epidermis/ skin
Location of transitional epithelium
urinary bladder
Vertical plane dividing the body into anterior (front) and posterior (back) parts
coronal
Horizontal plane dividing the body into superior (top) and inferior (bottom)
parts
transverse
Vertical plane dividing the body into equal left and right halves
midsagittal
Parallel to midsagittal, but left or right of midsagittal; divides structure
into unequal portions
sagittal plane
Passes through structure at an angle
oblique plane
is formed by bones of the cranium
cranial cavity
formed by the bones of the vertebral column
vertebral canal
Larger than posterior cavity
– Does not completely encase organs in bone
– Partitioned by thoracic diaphragm into
* Superior thoracic cavity
* Inferior abdominopelvic cavity
ventral cavity
Significant difference between posterior aspect and ventral cavity—
subdivisions of ventral cavity are lined with
serous membranes
lines internal surface of body wall
parietal layer
covers external surface of organs
visceral layer
space between membranes
serous cavity
Liquid secreted by cells in serous membrane
– Acts as lubricant
– Reduces friction caused by movement of organs against body wall
serous fluid
abdominopelvic and thoracic cavity making up
ventral cavity
upper chest cavity
thoracic cavity
abdomen cavity
abdominopelvic cavity
—median space in the thoracic cavity
mediastinium
—two-layered serous membrane
pericardium
Outer layer, which forms the sac around the heart
Parietal pericardium
Forms the heart’s external surface
Visceral pericardium
Space between parietal and visceral layers containing serous fluid
pericardial cavity
two-layered serous membrane associated with lungs
pleura
Outer layer lines internal surface of thoracic wall
parietal pleura
Inner layer covers external surface of lungs
visceral pleura
Space between parietal and visceral layers containing serous fluid
pleural cavity
Contains most of the digestive system organs, kidneys, and most of the
ureters
abdominal cavity
Contains distal part of large intestine, remainder of ureters and urinary
bladder, and internal reproductive organs
pelvic cavity
two-layered serous membrane lining the
abdominopelvic cavity
peritoneum
Outer layer, which lines the internal walls of the abdominopelvic cavity
parietal peritoneum
– Inner layer, which covers the external surface of most abdominal and pelvic
organs
visceral peritoneum
– Potential space between parietal and visceral layers containing serous fluid
peritoneal cavity
Middle region, named for the
umbilicus (navel) that lies in its
center
umbilical reigon
Superior to umbilical
epigastric reigon
Inferior to umbilical
hypogastric reigon
Inferior to costal cartilages and
lateral to epigastric
Right and left
hypochondriac regions
Lateral to umbilical
Right and left lumbar
regions
simple cuboidal epithelium
stratified cuboidal epithelium
simple squamous epithelium
stratified squamous epithelium
simple columnar epithelium
pseudostratified ciliated columnar epithelium
