Answer 40

Epidermis

• prevents water loss through evaporation
• acts as a receptor organ
• provides a protective barrier for underlying tissues

Dermis

• layer of connective tissue that provides support and nourishment for the epidermis
• network of cells, fibers, blood vessels and gelatinous material
• serves as a blood reserve
• participates in sensory reception and temperature regulation

Hypodermis

• loose connective tissue that contains a pad of adipose cells (fat)
• Contours the body and serves as an energy reserve
• Fibres link the epidermis to the dermis and the dermis to the hypodermis

3) Stratum granulosum
4) Stratum spinosum
5) Stratum basale

Question 45

Why is the epidermis divided into five layers

Answer 45

As a generates new cells in the basal layer, they are pushed towards the surface.

As the cells move toward the surface, they undergo sequential changes in chemical composition in which the cells become keratinocized during the stages of differentation

Question 46

What are the effects of ageing on skin

Answer 46

The surface ridges flatten which causes them to appear less sharp

The loss of elasticity in the dermis causes the skin to become flaccid (wrinkle)

Question 47

Answer 47

Any injury that alters the basal layer template/infrastructure and

requires remarkable changes in the structure and physiology to repair the wound

Question 48

Using Alfred Hales research on the growth of friction skin, give a summary of the development of friction ridges

Answer 48

• 3 weeks; epidermis is one cell thick
• 6 weeks; The hand is paddle like, some volar pads are starting to appear
• 8 weeks; The fingers have separated and elongated, thumb rotated, major flexion creases appear (palm, then fingers)
• 10.5 to 12 weeks; volar pad regression, primary ridges form due to rapid division of basal cells, form down into dermis & up from basal layer, longest ridges form first, shorter ridges later
• 15-17 weeks; Time of Differentation; secondary ridges begin to appear, form between exisiting ridges, primary ridges cease to dev in that area
• 20 weeks; secondary ridges established, FR’s visible on surface, final config does not change after 20 weeks
• 20-24 weeks; secondary ridges develop to same depth as primary ridges, 23 weeks, dermal papillae form on top of dermis between primary/secondary ridges, hugging primary, at 24 weeks entire system is mature

Question 49

What are volar pads

Answer 49

Volar pads are transient swelling of tissue called mesenchyme under the epidermis on the Palmer surface of the hands and soles of the feet of the human fetus

Question 50

What is meant by volar pad regression

Answer 50

As the volar pads slow the growth after the 10th - 11th week, Their contour becomes progressively less distinct as they are overtaken by the faster growth of the surrounding skin

Question 51

What are the three main fingerprint pattern groups

Answer 51

Whorls, Loops, Arches

Question 52

Define the arch pattern

Answer 52

ridges enter on one side of the impression, form a wave or arch and flow out the other side

Question 53

Define the tented arch pattern

Answer 53

Possess is either an arch, an upthrust, or two of the three basic characteristics of a loop

Question 54

Define the loop pattern

Answer 54

One or more ridges enter on either side of the impression, recurve, touch or pass in imaginary line from the Delta to the core and terminate on the entering side

Question 55

Define the Whorl pattern

Answer 55

Has two deltas and at least one ridge making a complete circuit.

Maybe a spiral, oval, circular or any variant of a circle

An imaginary line drawn between two deltas must touch or cross at least one of the recurving ridges within the inner pattern area

Question 56

What are the two types of impressions recorded on the C-216

Answer 56

Rolled, plain and palms

Question 57

What are the three types of fingerprints found a crime scenes

Answer 57

Latent, visible, moulded

Latent, made of sweat and sebaceous oil, invisible to the naked eye and requires additional processing to be seen

Visible, made by blood, grease, ink. or dirt, easily visible to the human eye

Molded, three-dimensional impressions and can be made by pressing your finger in fresh paint, wax, soap or tar

Question 58

Question 62

What affects exposure of an image

Answer 62

Aperture, shutter speed, ISO

Question 63

How does a digital camera Capture an image

Answer 63

The aperture opens at the front of the camera

Light enters through the lens

A CCD or CMOS sensor captures the incoming light rays turns them into electrical signals

These electrical signals are called pixels

Pixels are assigned a number based on the colour and intensity of light received

Image is stored in electronica format such as RAW, TIFF or JPEG

Question 64

What does ISO mean in digital photography

Answer 64

International standard organization

Refers to the sensitivity of light; the higher the ISO number, the more sensitive the cameras internal sensor is to light

Answer 65

Area of acceptable sharp focus in front and behind the subject in which is being focussed on

Question 66

How can you increase your depth of field

Answer 66

1) use a shorter focal length lens
2) Increase the lens to subject (move further away)
3) use a smaller aperture; F22 has greater depth of field than F4
4) Re-focus on the hyper focal point

Question 67

What is meant by white balance in digital photography

Answer 67

Colour temperature of light measured in degrees kelvin

Question 68

What is the building block of a digital image

Answer 68

Pixels (picture element)

Question 69

What is meant by resolution and Digital imaging

Answer 69

Refers to the number of pixels in an image.
