Tissues

Question 1

high power objective

Answer 1

• greatest amount of magnification when viewing specimen

- to see details of specimen

Question 2

basement membrane

Answer 2

• underside of tissue is anchored to connective tissue by a thin, non living layer
• part of extra cellular matrix

Question 3

nerve cells/neurons

Answer 3

• sense changes

- respond by transmitting nerve impulses to other neurons or muscles or glands

Question 4

neuroglial cells

Answer 4

• support and bind components of nervous tissue
• carry on phagocytosis
• supply nutrients to neurons by connecting to blood vessels

Question 5

merocrine gland

Answer 5

• a watery, protein rich fluid gets released through the cell membrane by exocytosis
• without losing cytoplasm
• salivary, pancreatic glands and sweat glands of skin

Question 6

apocrine gland

Answer 6

• lose small portions of their glandular cell bodies during secretion
• cellular product and portions of the free ends of glandular cells pinched off during secretion
• mammary glands, ceruminous glands lining external ear canal

Question 7

holocrine gland

Answer 7

• entire cells filled with secretory products disintegrate
• release entire cells filled with secretory products
• sebaceous glands of skin

Question 8

iris diaphragm

Answer 8

regulates amount of light going through specimen

Question 9

fibroblast

Answer 9

• fixed cell in connective tissue
• large star shaped cells
• produce fibres by secreting proteins into extra cellular matrix of connective tissues

Question 10

goblet cell

Answer 10

• two single called glands in the lining of digestive

- produces mucous that consists of water and protein mucin

Question 11

smooth muscle tissue

Answer 11

• don’t have striations
• spindle shaped
• single central nucleus
• walls of hollow internal organs ex) stomach, intestine, blood vessels
• involuntary

Question 12

skeletal muscle tissue

Answer 12

• found in muscles that attach to bones
• voluntary
• long threadlike cells have cross markings called striations

Question 13

cardiac muscle tissue

Answer 13

• only in heart
• striated and branded
• complex network
• single nucleus
• involuntary

Question 14

tissue types

Answer 14

• epithelial
• connective
• muscle
• nervous

Question 15

epithelial tissues shapes

Answer 15

squamous
-flat irregular shaped

cuboidal
-cubed shaped cells

columnar
-rectangular shaped cells

pseudostratified columnar
-false appearance of layers

squamous stratified
-layers of cells

Question 16

collagen

Answer 16

• thick threads of protein
• flexible only slightly elastic
• tensile strength
• hold structures together

Question 17

elastin

Answer 17

• protein
• thin fibres branch
• stretch easily can resume original lengths and strength

Question 18

loose connective tissue

Answer 18

binds skin to the underlying organs and fills spaces between muscles

Question 19

adipose tissue

Answer 19

cushions joints and some organs

Question 20

dense connective tissue

Answer 20

binds muscle to bone and bone to bone

Question 21

blood supply to tissue

Answer 21

blood supply to dense connective tissue is low making tissue repair

Question 22

epithelial tissues general

Answer 22

• simple squamous ep
• simple cuboidal ep
• simple columnar ep
• pseudostratified columnar ep
• stratified s/c/c
• transitional ep
• glandular ep
