integumentary Flashcards
epithelial membrane
Covers body surfaces
Lines body cavities
Forms protective layers over organs
Consists of an epithelial layer combined with an underlying layer of connective tissue
cutaneous membrane
Skin is the layer of usually soft, flexible outer tissue covering the body of a vertebrate animal, with three main functions: protection, regulation, and sensation. Other animal coverings, such as the arthropod exoskeleton, have different developmental origin, structure and chemical composition.
mucous membrane
an epithelial tissue which secretes mucus, and lines many body cavities and tubular organs including the gut and respiratory passages.
serous membrane
a mesothelial tissue which lines certain internal cavities of the body, forming a smooth, transparent, two-layered membrane lubricated by a fluid derived from serum. The peritoneum, pericardium, and pleura are serous membranes.
serous fluid
any of various body fluids resembling serum,
peritoneum
membrane that lines the inside of your abdomen and pelvis
pleura
The parietal pleura is the thicker of the two membranes and it lines the pulmonary cavities.
pericardium
The pericardium is a membrane that encloses the heart and the roots of major heart vessels. It consists of two layers
synovial membrane
thin barrier that lines the inside of some of your joints.
skin
human skin, in human anatomy, the covering, or integument, of the body’s surface that both provides protection and receives sensory stimuli from the external environment.
integument
Integument is the outer covering of an organism that includes seed coat, rind, shell, fur, cuticle, etc that also protects the organs and the body parts
keratin
keratin, fibrous structural protein of hair, nails, horn, hoofs, wool, feathers, and of the epithelial cells in the outermost layers of the skin.
epidermis
The epidermis is the most superficial layer of the skin, lying above the dermis and hypodermis. It consists of several layers, including the stratum Basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum
dermis
The dermis is the layer of skin found deep to the epidermis and superficial to the hypodermis. Thickness of the dermis varies and can range from 0.6 mm (eyelid) to 3 mm (palmar and plantar skin).
stratum Basale
The bottom layer of the epidermis is called the stratum basale.
stratum spinosum
also known as the “prickle cell layer,” is the fourth layer of the epidermis located above the stratum basale. It is characterized by the presence of keratinocytes that appear spiny due to desmosomal connections, which are essential for providing strength and preventing infections in the skin.
stratum granulosum
The stratum granulosum is a layer of the epidermis located between the stratum lucidum and stratum spinosum
stratum lucidum
the outer epidermal layer and comprises of dead skin cells.
stratum corneum
The stratum corneum is the outermost layer of the epidermis. Sometimes referred to as the horny layer of the skin, the stratum corneum is composed mainly of lipids (fats) and keratin, the protein comprising human hair and nails, as well as structures such as horns, hooves, and claws of animals
melanin
complex polymer that originates from the amino acid tyrosine.
sebaceous glands
sebaceous gland or oil gland is a microscopic exocrine gland in the skin that opens into a hair follicle to secrete an oily or waxy matter, called sebum, which lubricates the hair and skin of mammals. In humans, sebaceous glands occur in the greatest number on the face and scalp, but also on all parts of the skin except the palms of the hands and soles of the feet. In the eyelids, meibomian glands, also called tarsal glands, are a type of sebaceous gland that secrete a special type of sebum into tears.
sebum
Sebum is an oily, waxy substance produced by the sebaceous glands
eccrine glands
Eccrine sweat glands (/ˈɛkrən, -ˌkraɪn, -ˌkriːn/; from Greek ek(s)+krinein ‘out(wards)/external+secrete’)[3] are the major sweat glands of the human body.[4] Eccrine sweat glands are found in virtually all skin, with the highest density in the palms of the hands, and soles of the feet, and on the head, but much less on the torso and the extremities. In other mammals, they are relatively sparse, being found mainly on hairless areas such as foot pads
apocrine glands
structures within your skin that produce and secrete different bodily substances like thick, oily sweat and earwax.
hair follicles
a small secretory cavity, sac, or gland.
arrector pili
one of the small fan-shaped smooth muscles
athlete’s foot
a fungal skin infection that usually begins between the toes.
boils and carbuncles
Boils and carbuncles are skin infections caused by Staphylococcus aureus bacteria
cold sores
Cold sores, or fever blisters, are a common viral infection. They are tiny, fluid-filled blisters on and around the lips. These blisters are often grouped together in patches. After the blisters break, a scab forms that can last several days.
contact dermatitis
Contact dermatitis is a skin condition characterized by:
Itchy rash caused by direct contact with a substance or an allergic reaction to it1.
Acute or chronic inflammation of the skin due to exposure to chemical or physical agents2.
Redness, soreness, or inflammation of the skin after direct contact with a substance3.
impetigo
common and highly contagious skin infection that mainly affects infants and young children. It usually appears as reddish sores on the face, especially around the nose and mouth and on the hands and feet.
psoriasis
Psoriasis is a long-lasting, noncontagious autoimmune disease characterized by patches of abnormal skin.[4][5] These areas are red, pink, or purple, dry, itchy, and scaly.
Basal cell carcinoma
Basal cell carcinoma is a type of skin cancer. Basal cell carcinoma begins in the basal cells
Squamous cell carcinoma
Squamous-cell carcinoma (SCC), also known as epidermoid carcinoma, comprises a number of different types of cancer that begin in squamous cells.
Malignant melanoma
Malignant melanoma is a serious form of skin cancer that begins in melanocytes, the cells responsible for producing melanin
