First level of the Epidermis

Stratum Basale (Basal layer)

2

Second layer of the Epidermis

Stratum spinosum (prickly)

3

Third layer of the Epidermis

Stratum granulosm (Granular)

4

Fourth layer of the Epidermos

Stratum lucidum (clear)

5

Fifth layer of the Epidermis

Stratum Corneum (Horney)

6

Name the four kinds of tissue

epithelum

connective

muscle

nervous

7

What is the role or function of epithelum

Forms the outer layer of the body surface or lines. Also covers the organs and walls. It is for protection, absorption, filtration, excretion, secretion, and sensory reception.

8

What is the role or function of connective tissue

Supports, protects and binds other tissue together. (bones, tendons, and fat and other soft padding tissue.)

9

What is the role or function of muscle tissue

Contracts and causes movement. Muscles attached to bones (skeleton), Muscles of the heart (cardia) and muscles of the walls of hollow organs (Smooth)

10

What is the function of the role of the nervous tissue

Internal communication. Brain, spinal cord and nerves.

11

What is simple epithelia

It is a single cell layer. They are typically found where absorption, secretion and filtration occur.

12

What is stratified epithelia

It's two or more cell layers. common in high abrasion areas where protection is common.

13

describe squamous cells

They're flattened and scale like

14

describe columnar cells

They're tall and column shaped

15

describe cuboidal cells

They're box like, approximately as tall as they are wide.

16

What is the difference between exocrine and endocrine glands

Endocrine glands loose their ducts (ductless) and produce hormones, messenger chemicals that they secrete by exocytosis. while Exocrine glands produce onto the body surface (skin) or into the body cavities.

17

Merocrine glands and Holocrine glands

Merocrines secrete their products by exocytosis as they are produced.

Holocrine accumalate their productd until they rupture.

18

What are three connective tissue cells

Fibroblast, chondroblast, osetoblast

19

What are the ABCD/E rule?

Asymmetry: Two sides of the pigmented spot or mole do not match.

Border irregularity: The borders of the lesion exhibit indentations.

Color: The pigmented spot contains several colors (blacks, browns, tans and sometimes blue or reds.)

Diameter: The spot os larger than 6mm in diameter (the size of a pencil eraser)

(Some experts add an E, for evolution or evolving (changes with time)).

20

What type of cell doesn't have a nucleus?

A blood cell
