Intro to anatomy

100

Difference in anatomy and physiology

anatomy is study of structure of human body physiology is the study of the function of human body

200

This plane separates the body into anterior and posterior sections.

coronal/frontal

300

In relation to each other, the lungs are __________ to the heart.

lateral

400

This region is in the upper right hand region of abdominopelvic cavity when the specimen is in the anatomical position.

Left hypochondriac

500

Name 3 necessary life functions.

maintain boundaries movement responsiveness digestion metabolism excretion reproduction growth

Tissues

100

This tissue lines most of the body's cavitites and covers the body's surface.

Epithelial

200

This type of tissue allows diffusion and filtration in the air sacs of lungs, lining of heart and blood vessels.

Simple squamous

300

This tissue is found in the lining of the digestive tract.

pseudostratified ciliated columnar epithelium

400

This type of tissue forms the embryonic skeleton, found in costal cartilages and trachea, and is the most abundant form of cartilage.

Hyaline cartilage.

500

This type of tissue is striated, branched, uninucleated, and involuntary.

Cardiac

Vocabulary

100

layers of cells that cover internal or external surfaces

epithelia

200

structures that produce fluid secretions

glands

300

specialized areas of the plasma membrane that attach a cell to another cell or to extracellular materials.

cell junctions

400

epithelial stem cells located near the basement membrane

germinative cells

500

name the two types of cell junctions

gap and tight

Epithelium

100

one layer of cells covers the basement membrane

simple epithelium

200

several layers of cells cover the basement membrane

stratified epithelium

300

are thin, flat, and somewhat irregular in shape, like pieces of a jigsaw puzzle.

squamous epithelium

400

is the body’s most delicate type of epithelium. This type of epithelium is located in protected regions where absorption or diffusion takes place, or where a slick, slippery surface reduces friction.

simple squamous epithelium

500

The simple squamous epithelium that lines the body cavities enclosing the lungs, heart, and abdominal organs

mesothelium

Types of Epithelia

100

is generally located where mechanical stresses are severe

stratified squamous epithelium

200

resemble hexagonal boxes from their apical surfaces. (In typical sectional views they appear square.) The spherical nuclei are near the center of each cell, and the distance between adjacent nuclei is roughly equal to the height of the epithelium.

cuboidal epithelium

300

a columnar epithelium that includes several types of cells with varying shapes and functions. Found in portions of the respiratory tract.

Pseudostratified columnar epithelium

400

is an unusual stratified epithelium. Unlike most epithelia, it tolerates repeated cycles of stretching and recoiling (returning to its previous shape) without damage.

transitional epithelium

500

is typically found where absorption or secretion takes place, such as in the small intestine.
