U,T,C
What do the microtubules form?
Cilia
flagella
centrioles
Mitotic spindle
What is the purpose of microfilaments?
Also called actin filaments, they use actin and myosin for movement
What is the purpose of the intermediate filaments?
to give the cell mechanical strength, and serve for transport of organelles
Purpose of rough ER?
to synthesize protein
abundant is found in cells along with golgi where protein is needed
what is the purpose of the smooth ER?
Fatty acid synthesis
phospholipid synthesis
metabolism
helps liver to detoxify
What is the purpose of the golgi?
protein modification
packaging and excretory center
In what cells can an abundant of golgi and rough ER be found?
n cells that produce and secrete proteins
immune
pancreas intestine
What is the formula for the number of bacteria after generations?
b = B*2^n b= bacteria after B = original bacteria n = generations
What is a nonsense mutation?
a mutation that results in a premature stop codon (caused by a point mutation)
what is a missense mutation?
a point mutation that results in a substitution of a different amino acid
What is the function of the thalmus?
relay center for sensory input
what is the function of the cerebellum?
coordination and control of muscle tone
What is the function of the medulla?
Vital center for breathing heart rate and ateriole blood pressure
What is the vagus nerve?
it is a cranial nerve that control:
speech
swallowing slowing the heart
sensory and motor innervations to smooth muscles of the thorax and abdomen
What is the brain divided into?
forebrain
midbrain
hind brain
what is the hind brain divide into?
cerebellum
pons
medulla
(medulla and pons makeup brainstem)
What is the telencephlon?
The cerebral hemispheres (cerebrum)
What is the main function of each hemisphere?
left hemisphere- language
right hemisphere- pattens and spatial relationships
What are the divisions of the hemisphere?
Occipital
temporal
parietal
frontal
What is the function of the occipital lobe?
receives input from the optic nerve
What is the function of the temporal lobe?
receives auditory signals for hearing
What is the function of the parietal lobe?
receives somatosensory for the other side of the body
heat, pain cold, touch, sense of body movement
