what is the acessory organ of intagumentary
hair
nail
hoof
claws
feather
scales
the largest component of this system. It is an extensive sensory organ, which forms an outer, protective coat around the entire external surface of the body.
skin
what is the components of intagumentary system
Skin
- Skin Appendages
- Subcutaneous Tissue and Deep Fascia
- Mucocutaneous Junctions
These are the areas where skin meets mucous membranes
5. Breasts
give five function of integumatary
Covers about 2 square meters, and 1.5 to 5 mm thickness.
Acts as a protective barrier against environmental factors.
Protect deeper tissues.
Serves to maintain water balance.
Regulate body temperature.
the ________ stores fats, ______ over underlying structures, and provides insulation.
underlying hypodermis and “cushions”
give 2 underlying hypodermis
Synthesize vitamin D.
A sensory organ
give 4kinds of skin glands
sweat glands
Sebaceous Glands or Oil Glands
CERUMINOUS GLANDS
MAMMARY GLANDS
Respond differently to heat
and nervous state and respond to emotional
sensory stimuli.
sweat glands
2 type of sweat glands
Apocrine Sweat Gland
Eccrine Sweat Glands
Common in armpits and groin area.
The sweat does not evaporate as quickly and can lead to foul body odor.
is often a result of emotional stress or anxiety.
Apocrine Sweat Gland
The most common and are found all over the surface of the body.
Eccrine Sweat Glands
Found in the skin of mammals and these glands secrete sebum. It also contains a group of specialized epithelial cells.
Sebaceous Glands or Oil Glands
A group of complex oils.
sebum
A modified apocrine glands located primarily in the skin lining
cartilaginous/membranous portion of the external auditory canal.
CERUMINOUS GLANDS
It is involved in skin problems such as acne and keratosis pilaris.
CERUMINOUS GLANDS
Secretes Cerumen (Earwax)
CERUMINOUS GLANDS
CERUMINOUS GLANDS protects from?
- Dehydration
- Insects
- Entry of foreign objects
An organ developing on each side of the anterior chest wall.
MAMMARY GLANDS
the thick layer of living tissue below the epidermis which forms the true skin.
containing blood capillaries, nerve endings, sweat glands, hair follicles, and other structures
dermis
It produces milk for the sustenance of the young
MAMMARY GLANDS
is the outermost layer of skin on your body.
epidermis
It protects your body from harm, keeps your body hydrated, produces new skin cells and contains melanin, which determines the color of your skin.
epidermis
give 5 stratum of epidermis
Corneum
Lucidum
Granulosum
Spinosum
Basale
Consisting of dead tissue,
it protects from:
infection
dehydration
chemicals
mechanical stress.
It is composed of 15–20 layers of flattened cells with no nuclei and cell organelles.
Corneum
translucent appearance under a microscope.
Lucidum
is a thin, clear layer of dead skin cells
Think skin
which are found on the palms of the hands and the soles of the feet.
lucidum
is a thin layer of cells in the epidermis lying above the stratum spinosum and below the stratum corneum
Granulosum
Keratinocytes migrating from the underlying stratum spinosum become known as
granular cells
contain keratohyalin granules, which are filled with histidine- and cysteine-rich proteins that appear to bind the keratin filaments together.
Granulosum
This layer is composed of polyhedral keratinocytes.
These are joined with desmosomes.
spinous layer/prickle cell layer in latin
spinosum
referred to as stratum germinativum)
is the deepest layer of the five layers of the epidermis, the external covering of skin in mammals.
basale
Other types of cells found within the stratum basale are ______ and_______
melanocytes (pigment-producing cells) and Merkel cells (touch receptors)
3 layers of skin
epidermis
hypodermis
dermis
constitute the outermost layer of the skin and are responsible for the re-epithelialization process during wound healing
Keratinocytes
is a substance produced by keratinocytes in the skin, particularly in the stratum granulosum layer, which plays a role in the formation of eleidin and eventually leads to the production of keratin.
Keratohyalin
is the bottom layer of skin in your body.
It has many important functions:
including storing energy,
<connecting the dermis layer of your skin to your muscles and bones,
<insulating your body and protecting your body from harm.
hypodermis
