Histology

Question 1

Answer 1

simple squamous epithelium

Found in: lining of blood vessels and body cavities, kidney tubules, cornea, alveoli of lungs

Functions: acts as a semipermeable barrier

Question 2

Answer 2

stratified cuboidal epithelium

(2 layers)

Found in: rare, in lining of some ducts

Functions: protection, secretion, absorption

Question 3

Functions: acts as a semipermeable barrier

Question 4

Answer 4

simple cuboidal epithelium

Found in: walls of secretory/excretory ducts, glands, kidney tubules, thyroid gland

Functions: protective barrier, regulates ion and water concentration, secretion, absorption

Functions: protective barrier, regulates ion and water concentration, secretion, absorption

Question 6

Answer 6

simple columnar epithelium

Found in: lining of stomach, intestine, gallbaldder, uterine tubes, kidney ducts

Functions: protection, secretion, absorption, propulsion of mucus (if ciliated)

Question 7

Functions: protection, secretion, absorption, propulsion of mucus (if ciliated)

Question 8

Answer 8

non-ciliated pseudostratified columnar epithelium

Found in: trachea, ducts of the female and male reproductive systems, lining of nasal cavity and bronchi

Functions: protective barrier

Question 9

Answer 9

ciliated pseudostratified columnar epithelium

Found in: trachea, ducts of the female and male reproductive systems, lining of nasal cavity and bronchi

Functions: protective barrier, (b/c ciliated) moves surface mucus and debris

Question 10

Answer 10

transitional epithelium

Found in: lining of renal pelvis, ureters, urinary bladder

Functions: permits expansion and recoil after stretching

Question 11

Answer 11

non-keratinized stratified squamous

(all living nucleated cells)

Found in: oral cavity, esophagus, vagina
Functions: protective barrier that is less resistant to water loss

Question 12

Answer 12

keratinized stratified squamous

(superficial cells are dead and filled with protein keratin)

Found in: skin
Functions: protective barrier against friction, abrasion, infection, water loss

Question 13

Answer 13

stratified cuboidal epithelium

(2 layers)

Found in: rare, in lining of some ducts

Functions: protection, secretion, absorption

Question 14

Answer 14

muscular tissue: smooth muscle

(cells are long, cylindrical, striated, and multinucleated)

Found in: skeletal muscles

Functions: moves or stabilizes the skeleton, guards entrances and exits of tracts, generates heat, protects internal organs

Question 15

Answer 15

loose connective tissue: adipose

Found in: deep to skin at sides, butt, and breats; padding around eyes and kidneys

Functions: provides padding and cushions shocks, insulates, stores energy

Question 16

Answer 16

muscular tissue: cardiac

(cells are short, branched, and striated; single nucleus usually; cells connected by intercalated disks)

Found in: heart

Functions: circulates blood, maintains blood pressure

Question 17

Answer 17

connective tissue: bone

Functions: support, attach skeletal muscles, protect internal organs

Question 18

Answer 18

dense connective tissue: irregular

Found in: dermis (second layer of skin), visceral organ capsules, periostea, perichondria, nerve and muscle sheaths

Functions: resists stretch, prevents overexpansion

Question 19

Answer 19

dense connective tissue: regular

Found in: tendons, ligaments, between vertebrae

Functions: cushions shocks, allows expansion and contractions, firm attachments, reduceds friction, stabilizes positions

Question 20

Answer 20

connective tissue: hyaline cartilage

Found in: tips of ribs and sternum, covering at synovial joints, supporting larynx, trachea, and bronchi, nasal septum

Function: provides stiff, but somewhat flexible support, reduces friction

Question 21

Answer 21

connective tissue: elastic cartilage

Found in: ear, auditory canal, larynx

Functions: provides support but tolerates distortion without damage

Question 22

Answer 22

loose connective tissue: areolar

Found in: dermis, lining of tracts, between muscles, around blood vessels, nerves, and joints

Functions: cushions organs, provvides support but allows movement, defense against pathogens

Question 23

Answer 23

loose connective tissue

Found in: walls of organs, isolated spaces in dermis, surrounds vessels and nerves, under epithelia, spaces between tissues

Functions: suspends vessels and nerves, supports epithelia, fills spaces between tissues

Question 24

Answer 24

connective tissue: blood
