vt8 histology

Question 1

simple squamous tissue

Answer 1

single layer
function: in regions of the body where protection is not important, allows diffusion, filtration, secretion, and absorption. Lungs , ovioly, capillaries

Question 2

stratified squamous tissue

Answer 2

cells along basement membrane . SKIN
Non keratinized epithelium is found lining the mouth esophagus and vagina
Keratinized epithelium cells are found in the peidermis the superficial layer of the skin
Protection

Question 3

simple cuboidal

Answer 3

Tubules of kidneys,ducts,glands,terminal bronchioles in lungs, choroid plexus of brain, surface of ovaries
absorption and secretion in kidneys,

Question 4

stratified cuboidal

Answer 4

ducts of mammary glands, sweat glands, salivary glands

secretion absorption protection

Question 5

simple columnar

Answer 5

MICROVILLI
nonciliated:lines digestive tract from stomach to rectum,gallbladder, excretory ducts of some glands,
Ciliated cells assist with movement of particles out of the lungs and with the movement of particles out of the lungs
GOBLET CELLS

Question 6

stratified columnar

Answer 6

large ducts of mamary glands and small portion of urethra of some male animals

Question 7

pseudostratified columnar

Answer 7

each cell is attached to basement membrane
CILIA, GOBLET CELLS
Respiratory tract, nasal cavity, larynx, pharynx, trachea, bronchi

Question 8

transitional epithelium

Answer 8

composed of cuboidal or columnar
Urinary bladder, ureters, urethra
Transitional epithelium is flexible to accomadate amount of urine in bladder ureters and urethra

Question 9

Areolar connective tissue

Answer 9

Loose array of fibers includes macrophages, fibroblasts, mast cels, and some white blood cells.
Throughout the body, under epithelial basement membranes, between GLANDS MUSCLES AND NERVES surounding capillaries in many organs
Provides nutrients to tissues that it surrounds and supports

Question 10

Adipose tissue

Answer 10

Throughout the body, under the skin, around the heart, and kidneys, within mesenteries and omentum, and around colon.
Thermoinsulator:protects organs and other tissues it surrounds

Question 11

Reticular connective tissue

Answer 11

Spleen, lymph nodes, and bone marrow

provides internal skeleton for hematopoietic and lymphatic tissue

Question 12

dense regular connective tissue

Answer 12

Tendons and ligaments,Tendons attach muscle to bone, and ligaments attach bones to one another
Resists strong pulling forces great stretch capacity

Question 13

dense irregular connective tissue

Answer 13

dermis of skin, organ capsules, submucosa of digestive tract
designed to withstand pulling forces in all directions
Kidneys testes liver dense round organs

Question 14

hyaline cartilage

Answer 14

collagen fibers evenly distributed throughout a rigid matrix
cartilage cells or CHONDROCYTES sit in spaces within the matrix called lacunae
Articulating surfaces of bones : costal cartilages of ribs: cartliages in nose trache larynx and most embryonic skeleton
Silvery white pink gray

Question 15

elastic cartilage

Answer 15

firm matrix arranged in lacunae 
External ear (pinna) auditory tubes, epiglottis provides support and even more flexibility than hyaline cartilage

Question 16

fibrocartilage

Answer 16

pubic symphysis invertebral disks disks in stifle and knee joints also found in temporomandibular joint of jaw
withstands compressive forces

Question 17

compact bone

Answer 17

chambers called lacunae and tunnels called canaliculi form spaces in hard matrix to accommodate bone cells (osteocytes) and their long cytoplasmic projections
provides support protection blood is produced in bone marrow provides storage depot for calcium and other types of minerals

Question 18

blood

Answer 18

cells in fluid matrix
FOUND IN BLOOD VESELS AND HEART
carries oxygen and nutrients to tissues transports waste products and gases for disposal
PLASMA IS THE MATRIX

Question 19

smooth muscle

Answer 19

nonstriated, involuntary, composed of small, spindle shaped cells that lack striations or bands appear “smooth”
In walls of hollow organs such as the esophagus stomach intestine colon blood vessels an bladder also in skin attached to hair and in the iris of the eye
Moves food though digestive tract regulates the size of organs controls light entering eyes moves fluid through vessels causes hair to erect

Question 20

cardiac muscle

Answer 20

striated involuntary ; cells are cylindrical and branched with a single centrally located nucleus
found only in heart
pumps blood through the vascular system
intercelated disks

Question 21

skeletal muscle

Answer 21

striated voluntary cells are sriped long and cylindrical
attached to bone and occasionally skin, eyebals, and upper part of the esophagus
voluntary movement of body including movementn of they eyes and the initial part of swallowing

Question 22

nervous tissue

Answer 22

composed of neurons and supportive neurological cells. A neuron may be multipolar or unipolar.
Brain spinal cord and nerves
to conduct electrical signals store information and evalute data; to transmit sensory information to spinal cord and brain

Question 23

dendrites

Answer 23

receive the signal

Question 24

cell body

Answer 24

contains nucleus

Question 25

axons

Answer 25

send the signal

Question 26

schwann cells

Answer 26

nurologial cells
