FGCU A&P 1: Exam 1 review
What is the extracellular matrix in connective tissue made of? - ground substances and fibers
Regions: - right/left hypochondriac, epigastric, right/left lumbar, umbilical, right/left iliac or
inguinal, and hypogastric
Primary tissue types - epithelial, connective, muscle, nervous
How long does it take for keratinocytes to travel to surface and slough off? - 25-45 days or one
month
cytology - study of cells
Malignant melanomas - least common, most malignant, come from the melanocytes in the
stratum basale
eccrine sweat gland - everyday sweats, after exercising, help in regulating body temp
Apocrine sweat gland - becomes active at puberty (axillary and anogenital area)
negative feedback mechanism - reduces the intensity of the stimulus (ex:body temperature and
blood glucose levels)
What are the quadrants? - right upper, right lower, left upper, and left lower
What are KCI or NaCI examples of? - symbols
1st degree burn - affects epidermis only, redness, swelling, and pain
, 2nd degree burn - epidermis and part of dermis, blisters
3rd degree burn - affects all layers of the skin and some muscle and nerve
painless because nerve endings are destroyed
Skeletal system - provides a framework for the body
urinary system - gets rid of nitrogenous waste
Depolarization - reduction of membrane potential towards zero
Hyperpolarization - when membrane potential goes past RMP
Gated channels - can be open or closed
Leakage channels - always open
Types of connective tissue - connective tissue proper, cartilage, bone, and blood
How is connective tissue classified? - connective tissue is classified by its extracellular matrix
What are skin appendages derivatives of? - the epidermis (hair, nails, sweat glands, sebaceous
glands)
Rule of nines - used to estimate fluid loss from 2nd and 3rd degree burns only
What is melanin responsible for? - skin color (ranges from yellow-black)
