Lab 2 Flashcards
Purpose of muscular tissue?
locomotion, propulsion, posture, heat generator
Epithelial does what
protects
Simple columnar can be ______, ______,________
ciliated, non-ciliated, have microvili
simple columnar is found in
gut lining, lung tract, intestine
simple columnar is responsible for
movement and increases surface area
stratified squamous is found in
vagina and skin (where abrasive force is common)
stratigied squamous can be
keratinized or non-keratinized
keratinized makes a cell
waterproof
simple squamous is found in
aveoli
simple squamous is involved in
gas exchange and quick diffusion
simple cuboidal is found in
small intestines and kidney ducts
simple cuboidal is responsible for
secretion, absorption, facilitated diffusion
pseudostratified columnar is found in
trachea
connective tissue is responsible for what
binding, support, infection, protection, repair, insulation
connective tissue consists of
ECM and cells
EXM consists of
structural protetins and ground substance
examples of structural proteins includes
collagen, elastin, reticular fibers
ground substance separates
2 adjacent cells
fibroblasts secrete
ECM
which cell secretes ECM
fibroblasts
bone ground substance is
calcified
blood ground substance is
fluid
Classify connective tissue
loose proper, dense proper, cartilage, bone, blood
list connective tissue cell types
adipocytes, fibroblasts, chondrocytes, osteocytes, erythrocytes
adipocytes produce
loose adipose
fibroblasts produce
dense tendons and ECM
chondrocytes produce
cartilage
osteocytes produce
bone
erythrocytes produce
blood
intercalated disks connect
heart muscles
dense tendones have which proteins
high collagen and some elastin
bone has which protein
collagen
smooth muscle filaments are arranged
haphazardly
which muscle type is striated
skeletal and cardiac; not smooth muscle
why are smooth muscles not striated
bc their filaments are arranged haphazardly
intercalated disks contain proteins that form what
desmosomes and gap junctions
what do desmosomes and gap junctions do
desmosomes physically connect but gap junctions electrically connect
glial cell’s protection function is exemplified by what
immune function, BBB formation, CSF creation
cheek epithelial cell is
stratified squamous
define electromyography
records electrical events from muscle tissue
EMG classifies
muscle weakness
EMG and nerve conduction velocity classify
neuropathy
which muscle makes more force bicep or tricep?
bicep
coactivation of muscle is also called
antagonistic
integumentary system is made of which tissues
all four
which is the thinnest layer of the skin
epidermis
what is another name for hypodermis
fascia
dermis contains which proteins
elastin and collagen
collagen is responsible for what function
tear resistance
