Q

Stratum basale (layers)

A

Also called stratum germinivation

 Firmly attaches to dermis
Single row of stem cells
Produces two daughter cells

28
Q

Statum Lucium

A

Clear transparent found in palms and foot of soles

29
Q

What is the integumentary system and what does it consist of

A

It helps maintain a constant body temperature, protects the body and provide sensory information. It is composed of skin, hair, oil and sweat glands, nails and sensory receptors

30
Q

What is the epithelial tissue composed of

A

The epidermis

31
Q

What is the epidermis

A

The superficial thinner portion

32
Q

What is the dermis

A

The deepest thicker connective tissue

33
Q

What part of the epidermis and dermis is vascular versus a vascular

A

The epidermis is a vascular the dermis is vascular

34
Q

What is the subcutaneous layer

A

It is also called the hypodermis and consist of Arielar and adipose tissue’s

35
Q

What is the lamellated corpuscles?

A

Nerve endings which the subcuntaneoua aka hypodermis have

36
Q

What are keratinocytes

A

They are four or five layers and produce a protein called keratin

37
Q

What is keratin

A

A tough protein that helps protect the skin and underlying tissues from abrasions heat etc

38
Q

What are melanocytes

A

They produce melanin and develop in the ectoderm

39
Q

What is melanin

A

A yellow – red or brown – black pigment that contributes to skin color and absorbs damaging UV light

40
Q

What is intraepidermal macrophages aka langhern cells

A

They come from Red bone marrow and migrate to the epidermis. Their role in the Muni response is to help other cells of the immune system recognize in invading Microbe and destroy it

41
Q

What are Merkel self a.k.a. tactile epithelial cells

A

They are the least numerous of the epidermal cells located in the deepest layer of the epidermis

42
Q

What is tactile desk or Merkel disc

A

They detect touch sensation

43
Q

How many layers does the epidermis have

A

Four layers

44
Q

What are the layers of the epidermis

A

Stratum basale
Stratum spinosum
Stratum granulosum
Stratum corneum

45
Q

What is the layer stratum basale

A

Its the deeepest layer. It’s composed of single row of cuboidal or columnar keratinocytes.some cells in the layer are stem cells that undergo cell division to continually produce keratincocytes

46
Q

What is Stratam granulosum

A

It’s located in the middle of the epidermis and consist of 3 to 5 layers of flattened keratinocytes that undergo apoptosis ( aka cell programmed death which the nucleus fragements before it dies)

47
Q

What is keratohyaline

A

Assembles keratin intermediate filaments into keratin

48
Q

How long does it take for newly formed selves in the stratum basil to be pushed to the surface

A

4 to 6 weeks

49
Q

What is basale of the epidermal strata

A

The deepest layer composed of single row cuboidal or columnar keratinocytes

50
Q

What is spinosum

A

8 to 10 rows of many sided keratinocytes with bundles of Keratin

51
Q

What is granulosum

A

325 rows of Latin keratinocytes and which organelles begin to degenerate

52
Q

What is Lucidum

A

Present only in skin of fingertips, palms and soles

Has 4 to 6 rolls of clear, flat, dead keratinocytes with large amounts of keratin

53
Q

What is corneum

A

Few to fifty or more rows is dead flat keratinocytes that contain mostly keratin

54
Q

What is the reticular region of the dermis

A

It is attached to the sub cutaneous layer and contains bundles of the collagen fibers and various cells

55
Q

What is dermatoglyphics

A

The study of the pattern of epidermal ridges

56
Q

What are tension lines

A

They are lines of cleavage in the skin indicating predominate direction of underlying collagen fibers

(tension lines are especially important to plastic surgeons, if they don’t want to leave big scars.)

57
Q

What is papillary?

A

Superficial portion of the dermis consist of areole or connective tissue within collagen and fine elastic fibers

58
Q

Where is hair not present

A

The fingers souls and palms

59
Q

What is Subacious skin glands

A

Aka oil glands
They are simple branch Acinar rounded glands
They live in the dermis and usually open into the neck of a hair follicle

60
Q

What are sudofuris aka sweat glands

A

Glands that release sweat into hair follicules

61
Q

What are Eccrine sweat glands

A

They are simple coiled tubular glands that are much more common than Apocrine sweat glands

They are distributed through the skin of most regions of the body like for her palms and soles

62
Q

What is Thermo regulation

A

Regulation of body temperature

63
Q

What is Apocrine sweat gland found in armpits breast and face of males

A

Simple coil tubular plans they have larger docs and lumens

64
Q

What is the free edge in the nail

A

The free urges white because there are no underlying capillaries
