Integumentary System Flashcards
Largest organ of the body
Skin
An integument and associated structures with hair glands and nails constitute integumentary system
Skin
It is 7% of the body
Skin
It is a dynamic interface between the external environment
Skin
It consists of several kinds of tissues that are structured arrangely to function together
Skin as an organ
Dry membrane in the outermost protective boundary
Skin
What are the composed skin derivatives
But glance oil glands hair and nails
It insulates and cushions the underlying body tissue and protects them from mechanical damage chemical damage thermal damage and bacterial invasion
Skin functions as protection
It is the first line of defense
Skin
It prevents water loss from our body surface
Body temperature regulation
The body gets rid of urea salt and water through sweat
Excretion
Acts as a many excretory system where you we are souls and water are lost during sweating
Excretion
Acts as a many excretory system where you we are souls and water are lost during sweating
Excretion
Consists of loose areolar connective tissues
Stratum papillare
Name after its finger like projections the papillae
Stratum papillare
Extend towards the epidermis layer contains a network of blood capillaries or tactile Meissner’s corpuscles
Stratum papillare
This lies under the papillary region which is usually much more thicker
Stratum reticulare
Consists of dense irregular connective tissue
Stratum reticulare
Named after a dense concentration of collagenous elastic and reticular fibers that weave through it
Stratum reticulare
Allows the skin to play a role in regulating body temperature
Dermal blood supply
If the skin is exposed to the heat then our body creates wet to the skin surface if our body is face with cold temperature then our body constrict our muscles constrict when it is called but when it is hot or muscle engorged or expand
Take note
Skin is rich in nerve supply
Dermal cutaneous receptor
Transmits messages the essential nervous system for interpretation
Dermal cutaneous receptor
Nerve ending for a light touch
Meissners corpuscle
Mechanoreceptors found in the skin and mucosa vertebrates that providing information through the brain
Merkel’s disc
It detects pro prior reception
Pacinian corpuscle
Nerve endings in the skin that is responsible for sensitivity and vibration and deep pressure
Pa-sinian corpuscle
This vibrational role is you to detect surface texture
Pacinian corpuscle
Mechanoreceptor that is responsible for sensing position of hair
Hair follicle receptor
Sensitive to skin stretch and contribute to the kinesthetic sense of and control of finger position movement
Rufini’s corpuscle
Useful for monitoring sleep which of objects along the surface of the skins allowing modulation of grip of an object
Rufines model
It is derived from the latin word subcutaneous which means beneath the skin
Hypodermis
It is also known descent cutest or superficial fascia it is also the lower most layer of the integumentary system in vertebrates
Hypodermis
It is also known descent cutest or superficial fascia it is also the lower most layer of the integumentary system in vertebrates
Hypodermis
Consist primarily of loose connective tissues and lobules of fats
Hypodermis
Consist primarily of loose connective tissues and lobules of fats
Hypodermis
Contains larger blood vessels and nerves then found in dermis it anchors the skin to underlying organs it is composed mostly of adipose tissues
Hypodermis
It founds all over the body surface except for the palms of the hand the souls of the feet parts of the external genitalia the nipples and the lips
Hair
Which consists of several layers of thin flat cells laid out overlapping one another as roooff shingles
cuticles
Which contains the keratin bundle like structures determine roughly rodlike
cortex
It connects the hair to the dermis
Arrector pilli
When stimulated the hair will contract and cause it to stand perpendicular in the surface of the skin
Arrector pilli
Microscopic glands in the skin that secrete an oily or waxy matter called sebum in order to lubricate and waterproof the skin and hair
Sebaceous glands or oil glands
Are tubular structures in the skin that produces sweat
Sweat glands
Major sweat glands found in virtually all skin it produces an odorless clear substance consisting water and nacl
Eccrine sweat gland
Nacl is reabsorred in the doct to reduce salt loss and they are active in thermoregulation and emotional sweating it is induced by anxiety fear stress and pain
Eccrine sweat gland
Composed of a cold secretory portion located at the junction of the dermis and subcutaneous fact it is found in certain locations of the body such as the axilla areola and nipples ear canal islands wings of the nostrils perennial region and some parts of external genitalia
Apocrine sweat glands
It is the horn like derivatives of the epidermis it is transparent and nearly colorless that appear pink because of the blood supply in the underlying dermis
nail
it is caused by fungal infection
Athlete’s foot
It is caused by bacterial infection
Boils and carbuncles
It is caused by virus
Cold sores
It states that exposures can cause allergies
Contact dermatitis
Impetigo
Is caused by bacterial infection
The force of your skin becomes blocked with oil dead skin or bacteria
Acne
It is caused by an unknown it is triggered by trauma stress and infection
Psorias is
Also known as port wine stain it is the permanent birthmark found found usually at the face
Nevus flammeus
Bluish in color and it is typically found at the buttocks or lower back
Mongolian spot
A thiin spoon shaped nails
Koilonychia
It is redness and swelling around the nail s
paronychia
It is common with people has psoriasis
Pitted nails
He should damage in cell death of by heat uv radiation or chemical it is associated with dangers of dehydration electrolyte imbalance and circulatory shocked
Burn
This is when only the epidermis is damaged and the skin is red and swol len
The first degree burns
The severity of burns includes the epidermis and epidermis are damaged causing to form blisters
Second degree burns
Destroys the entire skin layer and only shows burn with gray or white or black
Third layer
Caused by tiny blood vessels bunch together and raised off the skin
Hemangioma
An inherited disorder is caused by the absence of the pigment melanin and result in low pigmentation of skin hair or eyes
Albinism
An inherited disorder is caused by the absence of the pigment melanin and result in low pigmentation of skin hair or eyes
Albinism
Tan or brown patches on the cheek knows foreheads and neck
Plasma
The melanocytes are destroyed as a result white patches appear on the skin on the different parts of the body
Vitiligo
It is the falling of hair
Alopecia
It is the falling of eyebrows
madarosis
Friends are considered critical if
25% of the body is second degree burn and 1
0% of the body is 30° burn or it is the t
here are third degree burns of the face hands or feet
It is the abnormal cell mass
Cancer
This type of cancer does not spread and it is encapsulated
Benign
This type of cancer metasized or moves to the different parts of the body
malignant
It is the most common cancer
Skin cancer
It is least malignant it is common type and it arises from the stratum basale
Basali cell carcinoma
Arises from stratum spinosum metacies into lymph nodes and an early removal has a chance for a cure
Squamous cell carcinoma
It is the most deadly skin cancers it is the cancers of melanocytes metasizes rapidly to the blood vessels and lymph and it use the detection of the abcd rule
Malignant melanoma
What is the abcd rule
Asymmetry border of irregularity color and diameter
It’s refers to the two sides of pigmented mole that do not match
Asymmetry
It refers to the borders of most that are not smooth
Border irregularity
It refers to the different colors in the pigmented areas
Color
It refers to the spot that is larger than 6 mm diameter
Diameter
