Intro To Gross Anatomy (1) Flashcards
Ipsilateral
Same side
Contra lateral
Same side
Intermediate
Between two structures
Parietal
Membrane or layer superficial to an organ
Visceral
Pertains to a membrane or layer directly adhered to an organ
Diaphragm
Anatomical landmark that separates the thoracic and the abdominopelvic cavity
Circumduction
360
What is one of the 8 characteristics of life?
Living things are organized
four basic types of tissues
epithelial, connective tissue, muscle tissue, nervous tissue
functions of epithelial tissues
covers surface of the body; lines body cavities, organs, and blood vessels; secretes enzymes, sweat and hormones if glandular epitheliem
what does glandular epithelium do?
secrete sweat, enzymes, and hormones. Found in glands, ovaries, testes, and parts of the eye
characteristics of epithelium
no blood supply, innervated, basement membrane between the epithelial tissues and connective tissue
How does epithelium get nutrients?
connective tissues supplies nutrients via diffussion
tight/occluding juncitons
impermeable junctions
Desmosomes/adhering junctions
bind adjacent cells together like velcro, tension reducing network
Gap Junctions/ communicating junctions
allow ions and small molecules to pass for intercellular communication
Endothelium
it lines blood or lymph vessels. Inner lining of cornea
Mesothelium
lines body cavaties
location for Simple Cuboidal Epithelium
glands
location for simply columnar epithelium
GI and respiratory tracts and parts of the uterus and glands
Goblet cells
Located in simple columnar epithelium of digestive tract for example. secrete mucus
what layer of the tear film is produced by goblet cells?
innermost layer, the mucous layer. produced in the conjunctiva
exocrine gland
glandular epithelium. a gland whose secretion is drained by ducts onto the body surface or into a body cavity. examples are sebaceous glands (oil), sudoriferous glands (sweat), and mammart glands (milk)
exocrine glands
glandular epithelium. “secrete outside”. unnicellular glands (goblet cells), multicellular glands.
Simple multicellular glands
exocrine gland having one duct leading from the secretory cells which does not branch
compound multicellular glands
exocrine glands having ducts which branch
How are exocrine glands classified by secretion?
mucus, serous, seromucous
How are exocrine glands classified?
number of cells, type of secretion, the way the gland releases its secretions.
merocrine glands
cells are NOT destroyed when the secretions are released with no loss of cellular material. Intact cellular components. Salivary gland
Apocrine glands
division of merocrine glands. cells are NOT destroyed when the secretions are released with bits of the cytoplasm. Mammary
Holocrine glands
the cells are ruptures and destroyed when the secretions are released. Oil gland
Types of connective tissue
bone, cartilage, dense regular connective tissue, blood, adipose
function of bone
support, protection of organs, muscle attachment, calcium storage, and blood cell production
function of cartilage
shock absorbers and flexibility
function of dense regular connective tissue
ligaments and tendons
function of blood
transportation of substances
function of adipose
protection, insulation, and energy reserve
characteristics of connective tissue
innervated (except cartilage), highly vascular (excpet cartilage and tendons), made up of cells, ground substance, and fibers
What connective tissue is not innervated?
cartilage
Which connective tissue is not vascular?
cartilage and tendons
-blast
to produce, to sprout. blast cells secrete matrix
