Q

embryonic stem cells (the types, and characteristics)

A
  • pluripotent and induced pluripotent stem cells
  • becomes all cell types

Q

adult stem cells (the types, location, characteristics, what it’s used for)

A

non-embryonic or somatic stem cells
- found in a tissue or organ
- can be differentiated to yield the specialized cell types of that tissue or organ
- used to repair specific cells

Q

induced pluripotent stem cells (what it’s used for)

A

adult stem cells that have been reprogrammed to be in an embryonic cell state
- used for drug discovery and disease modeling
- viruses are used to do the reprogramming

Q

mitosis cell cycle

A
  1. G1 - growth, preparation for DNA synthesis
  2. S - DNA replication
  3. G2 - growth, preparation for mitosis
  4. M - mitosis (prophase, metaphase, anaphase, telophase)
  5. cytokinesis

Q

cancer terminology (types of cancers) (just list them)

A
  • benign
  • malignant
  • metastasis
17
Q

benign cancer

A

a growth that is not cancer
- it does not invade nearby tissue or spread to other parts of the body

18
Q

malignant cancer

A

a growth that is cancerous
- can invade and destroy nearby tissue and spread to other parts of the body

19
Q

metastasis

A

the spread of cancer cells from the place where they first formed to another part of the body

20
Q

tumor suppressor gene

A

genes that normally function to suppress cell growth and division

21
Q

oncogene

A

genes that normally function to promote cell growth and division in a controlled manner

22
Q

tumor suppressor gene vs. oncogene

A

TSG suppresses cell growth and division, while OG promotes cell growth and division

23
Q

what are the four types of tissues?

A

epithelial, connective, muscular, nervous

24
Q

what does the epithelial tissue do?

A
  • covers body surface
  • lines cavities and ducts
  • forms glands

it’s basically protection. Because your skin is made up of epithelial tissue and your skin protects your body. and also since it lines cavities and ducts, it’s protecting the cavities and ducts

25
Q

classification of epithelial layers:

A
  • simple - single layer
  • stratified - stacked layer
  • pseudostratified - nucleus are not alligned
26
Q

classification of epithelial cell shapes:

A
  • squamos - flat shaped
  • cuboidal - cube shaped
  • columnar - column shaped
27
Q

glandelular epithelium

A

A type of tissue that lines certain internal organs and makes and releases substances in the body, such as mucous, digestive juices, and other fluids

28
Q

what does the connective tissue do?

A
  • protects and supports the body
  • bind organs together
  • stores energy reserves as fat
  • help provide immunity
29
Q

connective tissue examples (list 6 of them):

A
  1. loose connective tissue
  2. fibrous connective tissue
  3. bone
  4. adipose tissue
  5. cartilage
  6. blood
30
Q

what does the muscular tissue do?

A
  • makes the body move
  • generates heat
31
Q

muscular tissue examples (list 3 of them):

A
  • skeletal muscle
  • cardiac muscle
  • smooth muscle
32
Q

what does the nervous tissue do?

A
  • detects changes of conditions inside and outside the body
  • responds by generating action potentials
33
Q

nervous tissue examples (2 of them)

A
  • neurons
  • neuroglia
