Flashcards in Lab notes Deck (23):
1

Epithelial tissue

Lines or covers internal and external body surfaces
*3 Shapes-Cuboidal, Columnar and Squamous
*Stratified (more than one layer) and Simple (One layer)

2

Epithelial simple squamous

Delicate, thin-gas exhange

3

Epithelial stratified squamous

Tough, anti-abrasive coverings, rapid mitosis

4

Epithelial simple cuboidal

Absorb and secrete. Found in small tubules

5

Epithelial transitional

Change from cuboidal to squamous-line urinary passages

6

Epithelial simple columnar

Absorb and secrete. Found in large tubes

7

Pseudostratified ciliated columnar epithelium

In larger respiratory tubes

8

Muscle-Contractile tissue-

Cylindrical cells with evident nuclei

9

What are the 3 types of muscle tissue

1) Skeletal
2) Cardiac
3) Smooth

10

Skeletal muscle

Large, striated cells with multiple peripheral nuclei

11

Cardiac muscle

Small, striated cells with branches and intercalated discs

12

Smooth muscle

Small, non striated cells with tapering ends

13

Nervous tissue

Conductive cells and supportive cells
*Neuron-conductive cell with dendrites, nerve cell body and axon
*Neuroglia-Supportive cells of neurons

14

Epidermis

Stratified squamous epithelium

15

Hypodermis

Marked by adipose tissue

16

Accessory structures derived from the epidermis

1)Hair
2)Nails
3)Glands

17

The hair has

1) Follicle
2) Sebaceous gland
3) Shaft
4) Root
5) Hair papilla
6) Arrector pili muscle

18

The nails have

1) Free edge
2) Nail body (plate)
3) Lunula
4) Nail root
5) Nail bed
6) Eponychium (cuticle)
7) Hyponychium (quick)
8) Nail groove
9) Nail fold

19

The glands have

1) Sweat glands
2) Sebaceous glands

20

Golgi body

Modifies, packages, and sorts newly synthesized proteins for secretion, inclusion in new plasma membranes, or lysosomal enzyme synthesis

21

Structure of the Golgi body

Stacked series of flattened smooth membrane sacs with associated transport vesicles (also called shuttle vesicles)

22

Endoplasmic Recticulum (ER)

An extensive intracellular membrane network throughout the cytoplasm. Composed of 2 distinct regions that differ in structure and function: Smooth endoplasmic recticulum (smooth ER or SER) and rough endoplasmic recticulum (rough ER or RER)

23

Smooth ER

Continuous with rough ER. Walls have a smooth appearance. Resembles multiple interconnected branches of tubules. The smooth ER
