Q

Stages of mitosis

A

Prophase metaphase anaphase telophase

1
Q

Mitosis

A

One nucleus becomes two nuclei

2
Q

Prophase

A

Pre- beginning –

Chromatin condenses into chromosomes

3
Q

Metaphase

A

Chromosomes line up in middle

4
Q

Anaphase

A

Chromosomes start to pull apart

5
Q

Telophase

A

Looks like 2 attached prophase cells

Cleavage furrow

6
Q

Cytokinesis

A

Division of cell (cytoplasm)

7
Q

4 passive processes

A

Diffusion, facilitated diffusion, simple diffusion, osmosis

8
Q

2 active processes

A

Use ATP

Active transport, vesicular transport

9
Q

Vesicular transport works by

A

Endocytosis and exocytosis

10
Q

Three types of Endocytosis

A

Phagocytosis ( cell eating) , pinocytosis (cell drinking), receptor mediated endocytosis (plasma proteins bind certain substances)

11
Q

Identifying pseudo stratified epithelium

A

Simple columnar epithelium (one layer of cells) and cells vary in height and then nuclei lie at different levels

12
Q

Identifying transitional epithelium

A

Stratified squamous epithelium but cells may slide over one another

13
Q

Two types of glands

A

Endocrine and exocrine

14
Q

Endocrine

A

Ductless gland.

Secrete hormone into blood

15
Q

Exocrine gland

A
  • Have ducts.
  • Secretions empty through ducts to the body surface or into body cavities.

-Include the sweat and oil glands, liver, and pancreas.

16

Q

Dense connective tissue : dense regular

A

Very tight lines

18
Q

Dense irregular

A

Looks like raw meat collagen fibers go in all directions

19
Q

Dense CT elastic

A

Curly hair

20
Q

The avascular epidermis is a keratinized stratified squamous epithelium consisting of 4 cell types :

A

Keratinocytes- gives epidermis durability
Melanocytes
Dendritic- play role in immunity
Tactile (merkil) - touch receptors

21
Q

3 layers of dermis

A

Papillary layer
Dermal papillae
Then reticular layer

22
Q

Papillary layer

A

Areolar CT.

Very uneven, has finger-like projections from superior surface

23
Q

Reticular layer

A

Deepest skin layer
Made of Dense Irregular CT.
Has many veins, arteries, sweat and sebaceous glands, and pressure receptors.

24
Q

Cutaneous glands

A

Sebaceous (oil) glands

Sweat (sudoriferous) glands

25
Q

Sebaceous (oil) glands

A

Found all over skin

Produce sebum

26
Q

Sweat (sudoriferous) glands

Type or exocrine gland

A

Eccrine gland aka merocrine sweat glands
All over body
Heat regulation

Apocrine- axillary and genital
Produce eccrine sweat plus protein and fat substances
