lab test 2 Flashcards
simple squamous epithelium
irregular shape and lack of layering
simple squamous epithelium function
secretes, lubricates, filtration, diffusion,osmosis
Simple squamous epithelium locations
alveoli, walls of capillaries, kidney glomeruli
Stratified squamous epithelium
Irregularity shaped cells found in layers
Stratified squamous epithelium function
protection
Stratified squamous epithelium location
outer layer of skin, lining of mouth, throat, vagina and anal cavity
Simple cuboidal epithelium
cube-shaped cells often found lining tubes
Simple cuboidal epithelium function
secretion, absorption
Simple cuboidal epithelium location
lining kidney tubules, surface of ovary, lining ducts certain glands
Simple columnar epithelium
nuclei are all at about the same level which distinguishes
this from pseudostratified epithelium. Note the goblet cells.
Simple columnar epithelium function
ciliated propels mucous or reproductive cells, protection, secretion, absorption
Simple columnar epithelium location
lines uterus and digestive organs
pseudo stratified ciliated columnar epithelium
nuclei appear to be at different levels due
to crowding of cells. This is only one layer of cells
Pseudo stratified columnar epithelium function
protection, secretion, and movement of mucous
Pseudo stratified columnar epithelium location
trachea and male urethra
human blood
identify leukocytes and erythrocytes
human blood function
Delivers nutrients, oxygen, removes CO2, immune function
human blood location
blood vessels
frog blood
nucleated erythrocytes
hyaline cartilage
contains numerous fibers, identify lacunae, chondrocytes, and matrix
hyaline cartilage function
reinforce, cushions, resists compressions, supports, protects, provides framework
hyaline cartilage location
end of lone bone, nose, trachea, larynx, costal cartilage
adipose
large, empty looking cells with the nucleus found against the cell membrane
adipose function
protects, insulates, stores fat
adipose location
beneath skin, around kidneys, behind eye, surface of the heart, in bones, abdomen and breasts
compact bone
notice osteonic system. Identify lamellae, lacunae, canaliculi, Haversian canal, and osteocytes.
marrow inside for blood cell formation
compact bone functions
levers for muscle, stores Ca++, supports, protects, provides framework
compact bone location
skeleton, middle ear
dense white fibrous
wavy pattern of the collagen fibers
dense white fibrous function
withstands tensile strength in one direction, binds muscle to bone, bone to bone
dense white fibrous location
tendons, ligaments
areolar
a lot of intercellular space and fibers scattered throughout
areolar function
cushions organs, covey tissue fluid, binds organs together, holds tissue together
areolar location
beneath skin, between muscles, beneath epithelial tissue, mucous membranes, surrounds capillaries
smooth muscle
long, unbranched, unstriated fibers with a single nucleus per fiber
1 nucleus, no striations
smooth muscle function
Involuntary propels substances, motion of vessels, airways, and organs
smooth muscle location
walls of hollow internal organs, walls of arteries and arterioles
skeletal muscle
striations perpendicular to direction fiber run. they also have many nuclei per fiber. called voluntary muscle
skeletal muscle function
Voluntary movement of skeletal parts, facial expressions, posture, and manipulation
skeletal muscle location
attached to bones, and sometimes skin
cardiac muscle
striations, the presence of intercalated disks perpendicular to direction fiber runs, and the branching of the fibers. one nuclei
cardiac muscle function
Involuntary heart movement, circulation, propels blood
cardiac muscle location
heart muscle walls
neuron
examine individual nerve cells. the smaller cells are the neurgila
neuron function
Sensitivity and conduction of nerve impulse
neuron location
brain, spinal chord, peripheral nerves
