Ch. 1 & 2: Themes of A/P + Chemistry of Life
This is the feeling of a structure using the hands.
What is Palpation
Describe the structure of Fusiform shaped cells.
What is "thick in the middle, tapered towards the ends"?
What organelles contain ribosomes?
What is the layer of epidermis only found in "thick skin"?
What is the stratum lucidum
What is the function of an Osteoblast?
What is "to build bone tissue"
This scientist realized blood flows out from the heart then back to it.
Who is William Harvey
What is the primary function of flagella on a cell's surface? What cells are they present in?
Provide locomotion; Sperm cells only
Which gated channels respond to physical stress on the cell?
What is a mechanically-gated channel?
List the order of the layers of the thin epidermis from deep to superficial.
Stratum basale, spinosum, granulosum, corneum
Where is compact bone located?
On the external surface of bones.
A concentration gradient is where blood flows from areas of low pressure to high pressure. (T or F)
What is True
List the correct order of the cell cycle (complete order)
G1 -> S -> G2 -> Mitosis (PMAT)
Polygenic inheritance is defined as one gene contributing to multiple characteristics. (T or F)
False
Polygenic = multiple genes -> one characteristic
What type of tissue is responsible for processing information from the environment while sending signals?
What is the nervous tissue?
Give three examples of flat bones.
When an element is being reduced what happens to the number of electrons?
Electrons will increase (making it less positive)
What are the two types of Endocytosis? Describe the two.
Phagocytosis - "cell eating" engulfing large particles
Pinocytosis - "cell drinking" taking in small substances
This is known as the fingerprint region of the cell surface.
What is the Glycocalyx?
The embryonic tissue layer known as the Mesoderm, forms into what?
The inner linings of organs.
Calcitriol raises bone calcium levels. (T or F)
What is False? Raised blood calcium -> Lowers bone calcium
An atom has an atomic number of 24 and a mass number of 55. How many neutrons does this atom have?
What is 31? (neutrons = mass-protons)
What are the three types of RNA? Give the Function of Each.
tRNA - Delivers amino acids to the ribosomes
rRNA - facilitates protein assembly
Gene B is known to cause red colored hair, fair skin and freckles. What type of inheritance is this?
What is Pleiotrophy Inheritance?
(one gene -> multiple characteristics)
What cellular junction keeps cells from pulling apart?
(Tight Junction, Desmosome, Gap Junction)
What is Desmosomes?
Parathyroid hormone is most similar to which hormone?
What is Calcitriol?
Both raises blood calcium levels
