Know the four basic types of tissues and their function and origin (1)
|
Epithelial tissue covers the body surface and forms the lining for most internal cavities.
|
|
Know the four basic types of tissues and their function and origin (2)
|
Connective tissues perform a variety of functions including support and protection.
|
|
Know the four basic types of tissues and their function and origin (3)
|
muscle tissue produces force and cause motion, either locomotion or movement within internal organs
|
|
Know the four basic types of tissues and their function and origin (4)
|
Nerve tissue to perceive stimuli and generate nerve impulses to various organs of the body.
|
|
Discuss the major types of cell junctions (1)
|
Tight Junctions prevent intercellular passage of materials
|
|
Discuss the major types of cell junctions (2)
|
Desmosomes anchoring junctions hold adjacent cells together
|
|
Discuss the major types of cell junctions (3)
|
Gap Junctions communicating (transport) channels between adjacent cells.
|
|
What is the difference between covering and lining epithelium from glandular epithelium?
|
glandular epithelium are specialized for secretion. lining epithelium simply lines organs like the stomach.
|
|
Differentiate between exocrine and endocrine glands.
|
Endocrine glands release substances within the body and exocrine glands release substances outside the body.
|
|
Differentiate between the secretions of merocrine glands and apocrine glands.
|
Merocrine secretion - cells secrete their product through exocytosis and remain intact after secretion
Apocrine secretion - cells secrete their product by destroying their apex membrane so that the product flows out of the cell into the excretion duct. |

|
Fibroblasts- White Blood Cells
|
|
List the types of connective tissue cells and describe each cell (2)
|
Adipocytes (fats) macrophage
|
|
List the types of connective tissue cells and describe each cell (3)
|
mast cells - plamacells
|
|
Name the two major components of the extracellular matrix.
|
fibers and ground substance
|
|
List the types of mature connective tissue.
|
Loose connective tissue
areolar connective tissue adipose tissue reticular connective tissue dense regular and dense irregular connective tissue cartilage bone blood and lymph |
|
List the epidermal strata beginning with deepest layer to top layer. (1)
|
stratum corneum
|
|
List the epidermal strata beginning with deepest layer to top layer. (2)
|
Stratum Lucidum
|
|
List the epidermal strata beginning with deepest layer to top layer. (3)
|
Stratum Granulousm
|
|

|
Stratum Basale
|
|
What is the scientific explanation for fingerprints?
|
fingerprints, or "dermal ridges" are necessary for grip. If the skin on our fingers was completely smooth we would have a hard time keeping a grip on anything, especially if it is wet or our hands are sweaty.
|
|
dermatoglyphics
|
scientific study of fingerprints
|
|
List three accessory structures of the skin.
|
hair, nails and glands
|
|
Know the cell shapes in epithelial layers
|
Squamous
Cuboid Columnar |
|
describe the arrangement of cells in epithelial layers.
|
Simple epithelia Tissue
Pseudostratified Tissue Stratified Tissue |
|
Describe two epithelial membranes (1)
|
Mucous membrane lines all body passages that communicate with the air, such as the respiratory
|
|
Describe two epithelial membranes (2)
|
A thin, membrane that secretes a serous fluid and lines a closed body cavity, covering the organs that lie within that cavity.
|
|
What is the chemical composition of sweat produced by eccrine sweat glands?
|
water, ions, (Na+ amd Cl-) urea, uric acid, ammonia, amino acids, glucose, and lactic acid
|
|
When do apocrine sweat glands begin to function?
|
After puberty
|
|
How does the body make vitamin D?
|
activation of molecules in the skin by UV rays in sunlight.
|
|
How does the skin contribute to thermo regulation?
|
Skin participates in homeostatic regulation of body tempertures through sweating with evaporation cooling, and adjusting blood flow in the dermis.
|
|
Define "burns"
|
Burns are a type of traumatic injury caused by extreme hot or cold tempertures
|
|
First degree burn
|
A mild burn that produces redness of the skin but no blistering.
|
|
Second degree burn
|
A burn that blisters the skin and is more severe than a first-degree burn.
|
|
Third degree burn
|
A severe burn in which the skin and underlying tissues are destroyed and sensitive nerve endings are exposed.
