Stratum basale

21
Q

2nd to the bottommost layer of the epidermis
Consists of alive keratinocytes, Langerhans cells, and melanocytes

A

Stratum spinosum

22
Q

Middle layer of the epidermis
Consists of lamellar granules

Stratum lucidum

24
Q

Topmost layer of the epidermis
Consists of dead keratinocytes

A

Stratum corneum

25
Q

The cell/s present in the dermis

A

Fibroblasts, macrophages, and adipocytes

26
Q

10% of blood flow is around this layer. This layer of the skin is also known to be vascularized.

A

Dermal layer / Dermis

27
Q

A chronic (long-lasting) disease in which the immune system becomes overactive, causing skin cells to multiply too quickly.
Particularly, it involves hyperproliferation of the keratinocytes in the epidermis, with an increase in the epidermal cell turnover rate

A

Psoriasis

28
Q

The hypodermis is known as the storage of most ______

A

Body fat

29
Q

The hypodermis consist mostly of these tissues

A

Adipose tissue

30
Q

Lies between the dermis and underlying tissues and organs

It serves to fasten the skin to the underlying surface, provides thermal insulation, and absorbs shocks from impacts to the skin.

A

Hypodermis

31
Q

These are linear clefts in the skin that indicate the direction of orientation of the underlying collagen fibers.

They reflect internal tension within the skin due to connective tissue (e.g. collagen) within the dermis.

A

Tension lines or cleavage lines

32
Q

Non-harmful (benign) accumulation of melanocytes

A

Moles

33
Q

Age spots caused by the accumulation of melanin

A

Freckles

34
Q

A process that is based on melanocytes present among the basal cells of the epidermis as a defense mechanism against UV rays from sunlight (mainly) to prevent sunburn.

A

Melanin synthesis

35
Q

Disease caused by pathogenic variants in genes important for melanin synthesis

A

Albinism

36
Q

Secretes to the surface through the skin; secreted externally

A

Exocrine

37
Q

Secretes to the blood stream; secreted internally

A

Endocrine

38
Q

Collection of epithelial tissue that secretes either endocrine or exocrine

A

Skin glands

39

Form of skin cancer that is the least serious and around the stratum basale

A

Basal cell carcinoma (70%)

40
Q

Form of cancer that is the most serious. Known as the cancer of the melanocytes

A

Kind of sudoriferous gland that occur over most of the body and open directly onto the skin’s surface

A

Eccrine

44
Q

Type of skin gland that secrete sweat

A

Sudoriferous glands

45
Q

Type of skin gland that secretes oil/sebum. Often associated with hair follicles

A

Sebaceous glands
