Detailed Explanations 100% Pass
Cancer - CORRECT ANSWER-A disease in which some cells of a particular
tissue become abnormal and:
Don't carry out their functions
Continually make copies of themselves which leads to visible mass of cells (tumor)
Cancer cells on the periphery of a tumor break off & spread to other places in the
body (metastasize) where they attach & grow
Melanoma - CORRECT ANSWER-Worst type of skin cancer
Potentionally life threatening
Can spread rapidly from intial site
Can metastasize- "move" via the bloodstream from the epidermis
basal cell carcinoma - CORRECT ANSWER-Most common skin cancer
Cant metastasize
Slow growing > 95% can be cured (almost 100% if caught early)
, squamous cell carcinoma - CORRECT ANSWER-2nd most common skin cancer
Cant metastasize
Melanocytes - CORRECT ANSWER-Epithelial cells in deepest layer of epidermis
Produce (but don't release) melanin
Have cellular extensions of plasma membrane that allows cells to "creep" slowly
through the tissue
Normally creep significantly, die, & slough off
Melanin - CORRECT ANSWER-Brown pigment that absorbs potentially
dangerous UV radiation from the sun
cancerous melanocytes - CORRECT ANSWER-Creep down towards blood
supply
Cling to blood vessels walls & creep along & slip b/w epithelial cells lining the
blood vessel & gain entry into tissues
Red bone marrow - CORRECT ANSWER-Specialized blood tissue
Found inside spongy bone of sternum, hope, & heads of humerus & femur
Bone stem cells - CORRECT ANSWER-Have receptors embedded in their plasma
membrane that are specific for certain cytokines & hormones
