BIOL 241 Exam 1 Study Guide Actual
study with Questions and
correct/verified Answers
List the different types of tissue and give an example of each type - ANSW-epithelial- cutaenous,
connective-dense regular, muscle - skeletal, neural- nerve,
What is epithelium? - ANSW-a tissue that covers exposed surfaces, lines internal passageways, and forms
glands
Characteristics of epithelia - ANSW-avascular, regeneration, attached to other cells and basal lamina
Functions of epithelia - ANSW-permeability, secretion, protection, relays sensory info
Need to know to specify type of epithelia - ANSW-shape at apical layer and number of layers
Different terms used to describe shape/layers of epithelia - ANSW-simple/stratified, cuboidal, squamous,
columnar, transitional
Function of simple squamous epithelia - ANSW-absorption, secretion, protection
3 different locations where simple squamous is found - ANSW-mesothelium - lines body cavities,
endothelium- lines heart and blood vessels
function of stratified squamous epithelium - ANSW-protection, absorption, secretion
3 different locations of stratified epithelium - ANSW-skin, mouth, anus
functions of intercellular junctions - ANSW-form bonds with other cells or extracellular material
name 5 different intercellular junctions: which doesn't allow material movement, which allows - ANSW-
adhesion belt, tight (occluding) junctions (do not allow passage), gap junctions (allow passage through
channels), spot desmosome, hemidesmosome
what cell type produces new epithelia cells? - ANSW-stem cells near the basal lamina
Define an exocrine gland - ANSW-has a duct that secretes fluids through exocytosis to epithelial surfaces
of body. Ex: sweat glands
Define an endocrine gland - ANSW-ductless, release hormones directly into circulatory system. Ex:
pituitary glands
Different modes of secretion and how each work - ANSW-merocrine: released by vesicles (exocytosis),
apocrine: released by shedding cytoplasm ex: mammary gland, holocrine: released by cells bursting,
killing gland cells ex: sebaceous gland
function of connective tissue - ANSW-establish structural network for body, protection for delicate
organs, interconnects other tissue types, store energy
different structural components of connective tissue - ANSW-fibers, extracellular matrix
