Skin and Body Membranes Flashcards
(30 cards)
It is a system that simply means “covering”, performs a variety of functions but not all, of which are protective.
Integumentary System
It is tissue damage and cell death caused by intense heat, electricity, UV radiation, or certain chemicals which denature proteins and cause cell death in the affected areas
Burns
The portion of hair that you see that projects from the scalp surface is known as the:
A. Bulb
B. Matrix
C. Root
D. Shaft
C. Root
It is composed of two layers, the superficial epidermis, and the underlying dermis.
Cutaneous Membrane
These are small bands of smooth muscle cells that connect each side of the hair follicle to the dermal tissue.
Arrector Pili
It is a layer of the Epidermis which named for the abundant granules in its cell. Some of these granules contain a waterproofing glycolipid that is secreted into the extracellular space.
Stratum Granulosum
True or False: The visceral layer lines a specific portion of the wall of the ventral body cavity.
False: The Parietal layer lines a specific portion of the wall of the ventral body cavity.
They are often called ductless glands and their secretions (all hormones) diffuse directly into the blood vessels that weave through the gland.
Endocrine Glands
True or False: Eccrine glands are found primarily in the genital and axillary areas.
False: Apocrine glands are found primarily in the genital and axillary areas.
It is composed of a thin layer of simple squamous epithelium resting on a thin layer of areolar connective tissue.
Serous Membrane
It is the deepest layer of the epidermis. It is closest to the dermis.
A. Stratum Basale
B. Stratum Spinosum
C. Stratum Lucidum
D. Stratum Gabulosum
A. Stratum Basale
It is the deepest skin layer. (Dermis)
Reticular Layer
It is composed of loose areolar connective tissue and contains no epithelial cells at all.
Synovial Membranes
Enumerate the cardinal signs of inflammation.
Pain Redness Swelling Heat Disturbance
It develops the healing process as inelastic fibrous tissue replaces the normal elastic connective tissue.
Contractor
They are responsible for the toughness of the dermis.
Collagen Fibers
True or False: The ducts of sweat glands usually empty into a hair follicle but may also open directly on the skin surface.
False: The ducts of Sebaceous glands usually empty into a hair follicle but may also open directly on the skin surface.
This layer of the epidermis is present only in thick skin, such as the palms of the hands and soles of the feet.
A. Stratum Corneum
B. Stratum Lucidum
C. Stratum Basale
D. Stratum Spinosum
B. Stratum Lucidum
True or False: Nails are hornlike derivatives of the epidermis.
True
Enumerate the pigments that contribute to the skin color.
Melanin
Carotine
Hemoglobin
A type of muscle with no striations visible. The individual cells have a single nucleus and are tapered at both sides.
Smooth Muscle
It gives the skin its elasticity when we are young.
Elastic Fibers
It is a strong, stretchy envelope that helps to bind the body together.
Dermis
It is a pigment that ranges in color from yellow to brown to black, is produced by special spider-shaped cells called melanocytes.
