Anatomy

Front 1

What does the Human Integumenarty system consist of?

Back 1

Skin, glands, hair, and nails.

Front 2

What are the functions of the IS

Back 2

1. Protection

2. Regulation of body temperature

3. Vitamin D synthesis

4. Sensation

5. Waste removal

Front 3

What are the 3 main layers of the skin (superficial to deep)

Back 3

Epidermis, Dermis and Hypodermis

Front 4

What are the layers of the Epidermis (superfical to deep)

Back 4

Corneum

Lucidum

Granulosum

Spinosum

Basale

Front 5

What are the sections of the dermis and their function?

Back 5

1. Papillary layer- Binds the dermis to the epidermis

2. Deeper reticular layer- connects the underlaying subcutaneous

Front 6

Two types of epidermis?

Back 6

Thick- on palms and feet, has 5 layers composed of dead keratinocytes (extra lucidum layer)

Thin- only has 4 ( no lucidum layer)

Front 7

Explain the papillary layer

Back 7

Made of looseareolar connective tissue that contain fiberblast, collagen, reticular fibres and eslatin fibers

Front 8

Explain Deeper region layer-

Back 8

Attaches the the subcutaneous layer, dense irregular connective tissue containing bundles of collagen and coarse elastic fibers

Front 9

Skin colour is due to the pigments

Back 9

melanin, hemoglobin and carotene

Front 10

Melanin

Back 10

black-brown pigment

Front 11

Hemoglobin

Back 11

carries oxygen in rbc, looks reddish

Front 12

Carotene

Back 12

the orange-yellowish pigment

Front 13

What are glands

Back 13

single or groups of epithelial cells that secrete a substance

Front 14

Define the Sebaceous Glands

Back 14

oil glands, produce sebum that keep hair from drying out, prevents excessive evaporation of water from the skin, keeps skin soft and inhabits the growth of certain bacteria

Front 15

Define the Sudoriferous Glands

Back 15

They are sweat glands, the two types are:

1. Eccrine- main function to help regulate body temperature ( on palms, forehead, soles)

2. Apocrine- Open into hair follicles, and function during puberty, stimulated by emotional stress, and sexual excitement

Front 16

Define Ceruminous Glands

Back 16

Present in the outer ear canal, combines secretion of the ceruminous and sebaceous glands in a yellowish secretion ( earwax )

Provides a sticky barrier for protection

Waterproof preventing infection from entering the cells.

Front 17

What are the types of skin cancer and where does it occur in the skin?

Back 17

1. Basal cell carcinoma- originates in the basal cells (most common)

2.Squamous cell carcinoma - originates in the keratinocytes of the spinosum layer. (exsessive sun exporsure

3. Melanoma- uncontrollable growth of pigment

Front 18

What are the early warning signs of skin cancer?

Back 18

A: asymmetrical

B: borders are irregular

C: colour is dark, and inconsistent

D: diameter is larger than 6mm

E: Evolves over time

Front 19

What layers are burns consider first, secound and third

Back 19

First degree burns are in the epidermis layer. (superficial )

Secound are burns that reach the epidermis and the dermis layers. (partial thickness)

Third degrees burns are the epidermis, dermis and subcutaneous layers. (full thickness burn)
