Find true about the skin:

SALT system includes keratinocytes, T-lymphocytes and Langerhans cells

Reticular layer of dermis is composed of dense regular connective tissue

Reticular layer of dermis is composed of dense irregular connective tissue

Thickness of dermis varies depending on the region of the body

Bulb region of the hair does not contain stem cells

Stratum basale is also called stratum germnativum

In which layer of the epidermis desmosomes are present in highest number?(single choice)

Dermis:

Both layers contain collagen and elastic fibers

The first layer only contains collagen fibers

Is divided into papillary and reticular layer

Is divided into elastic and reticular layer

Secretory parts of eccrine sweat glands are located in superficial epidermis

Secretory parts of eccrine sweat glands are located in deeper dermis

Supports epidermis and binds it to the hypodermis

Reticular layer is composed of dense irregular connective tissue

Skin derivatives, find true:

Hair are elongated, keratinized structures derived from invaginations of epidermal epithelium

The hair follicle is responsible for the production and growth of hair

Sebaceous glands secrete sebum that coats hair and skin surfaces

Eccrine sweat glands are distributed only in compressed areas on the body surface (armpits)

Sweat glands are ectodermal in origin

� Apocrine sweat glands are limited to axilla, areola, nipple, anus and external genitalia

Each hair is composed of shaft of cornified cells and root

Eccrine sweat glands are distributed over the entire body surface

Langerhans cells of the epidermis:

Epidermis, find true:

Is composed of keratinized stratified squamous epithelium

S composed of non-keratinized stratified squamous epithelium

Keratinocytes produce keratins (cytokeratins)

Keratinocytes are main population of epidermis –

Epidermis:

There is no stratum lucidum in thin skin

There is stratum lucidum in thin skin

It is stratified squamous keratinized epithelium

Contains blood vessels

Is derived from ectoderm

Melanocytes are antigen-presenting cells

Stratum basale is also called stratum germinativum

Langerhans cells are antigen-presenting cells

Mark true sentence concerning skin:

No bodies of the melanocytes are present in the hypodermis

There are zonulae occludens between stratum basale cells and basal lamina

Thick skin covers palms

Langerhans cells can bind, process and present antigens to T-lymphocytes

In the skin of external auditory meatus there are only ‘apocrine’ sweat glands

Melanocytes are only present in stratum corneum

Melanin is synthesized in melanocytes

No bodies of the melanocytes are present in the stratum corneum

There are zonul aeadherens between stratum basale cells and basal lamina

Epidermis – find true: (Single choice)

The keratinocytes of stratum lucidum can proliferate

Is composed of non-keratinizing stratified squamous epithelium

Keratinocytes are main population of cells

Is derived from mesoderm

Find true about the skin:

Arrector pili muscles are composed of smooth muscle cells

Cells of stratum basale have low mitotic activity

Sebaceous glands are branched multicellular saccular glands

Papillary layer of dermis is composed of loose connective tissue

Langerhans cells can bind, process and present antigens

Dermis supports epidermis and binds it to hypodermis
