exam Flashcards
The tendency of molecules to stick together
cohesion
the clinging of one substance to another
adhesion
A measure of the difficulty to stretch or break the surface of a liquid
surface tension
a liquid mixture of two or more substances
solution
a dissolving agent
solvent
A substance that is dissolved
solute
The foods that we eat and the nutrition they contain
Nutrition
Nutrients that we need in large amounts
Macro nutrients
Nutrients that are need in very small amounts
micro nutrients
Carbs that must be broken down into simpler forms prior to absorption
Complex carbs
Sugars that still need to be broken down prior to absorption
Disaccharides
The Absorbable form of sugar
monosaccharides
When blood pressure is greater than 140
Hyperglycemia
When blood sugar is lower than 70
Hypoglycemia
When nutrient molecules enter the cells and undergo chemical changes
Assimiliation
Bad cholesterol
LDL
Good Cholesterol
HDL
A group of similar cells that perform a common function
Tissue
covers and protects the body surface
Epithelial tissue
Transports substances through the body
Connective tissue
Specializes in communication and integration
Nervous Tissue
The tissue moves the body and its parts
Muscle Tissue
You would find the following cells in the alveoli of the lungs
Squamos
You would find the following cells in glands and the ducts of glands
Cuboidal
You would find the following cells in the mucous membrane
Columnar
These cells collect their secretory product near the apex and release them into a duct by pinching off the distended causing some cell damage
Apocrine
These cells discharge their secretion product directly through a membrane without injury to the cell
Merocrine
These cells collect their secretory product inside the cell and then rupture to release it during total self destruction
Holocrine
Striated muscle that is involuntary
Cardiac
Nonstriated muscle that is involuntary
Smooth
Striated muscle that is voluntary
Skeletal
Which of the following tissues has the best ability to regenerate after trauma
Epithelial
I have one or more layers of densely arranged cells with very little extracellular matrix
Epithelial Tissue
Location where Epithelial tissue is found
Outer coverings
I have sparsely arranged cells surrounded by a large proportion of extracellular matric
Connective tissue
Location where connective tissue is found
Organs and joints
I have longs, fiber-like cells capable of pulling massive loads
muscle tissue
Where is a keloid found
Locations with significant damage
i am a type of scar that forms after a deep tissue trauma
Keloid
Another name for skin
integument
Superficial, thinner layer of skin
Epidermis
Deep, thicker layer of skin
Dermis
90% of all epidermal cells are of this type
Keratinocytes
Skin color and UV protection are here
Melanocytes
Presents invaders to the immune system
Langerhans cells
Layer of dermis responsible for friction ridges
Papillary
The more denser layers of the dermis
Reticular layer
The darker type of melanin
Pheomelanin
The lighter type of melanin
Eumelanin
Unlike the epidermis, the dermis does not continually shed and regenerate
true
Stretch marks are actually little tears in the dermis
true
The hypodermis is not a true layer of skin. It is the first layer of muscle
false
They type, not quantify of melanin determines how tanned or pale the skin is
false
A sun tan is actually the response of the body to protect from UV radiation
true
babies turn orange from fake-baking, not carotene consumption.
true
You will grow a beard one da. Frequent shaving will make this happen faster
false
Oxidation of sebum is what cause a blackhead
true
The “rule of nines” refers to epidermal cell production during puberty
false
Thin layer of hyaline cartilage that covers the articular surface of epiphyses
articular
Ends of long bone that provide for muscle attachment
epiphyses
Main shaft of a bone
diaphysis
White membrane that covers bone
periosteum
A hollow space in bone that is the location of bone marrow
medullary
Membrane that lines the medullary cavity
endosteum
Made from shark skeleton and cattle trachea, this supplement can reduce wear and tear
chondroitin sulfate
Made from shrimp, lobster and crab shells, this supplement aids aids in cartilage maintenance and repair.
glucosamine
This disease affects the elderly. There is a proliferation of osteoclasts and rapid bone remodeling
Paget’s
Bacterial infection of bone that can be caused by open wounds from bullets or fracture
osteomyelitis
A vitamin D deficiency that leads to demineralization and has potential for “bow legs”
Rickets
Characterized by an increase incidence of fractures of the femur and vertebrae
osteomalacia
Bone has nearly the tensile strength of iron at 1/3 the weight
true
Bone has no flexibility
false
Compact bone is very densely arranged and constitutes 80% of bone mass
true
Osteoblasts are large cells that erode bone tissue
False
Osteoblasts are small cells that contribute to bone formation
false
A toddler’s skeleton has a greater percentage of cartilage than and adult
true
Bones will respond to stress by growing weaker and less dense
false
When a bone breaks there is no chance that the bone could bleed
false
In an uncomplicated fracture a bone can heal without scarring in as little as three months
true
Cartilage has blood vessels. Nutrition comes to cartilage by means of perfusion
false
