Let’s say the synapses of a neuron’s dendrites are filled with glutamate-gated channels which, when activated by glutamate, cause an excitatory postsynaptic potential (EPSP) in the neuron. In one instance, glutamate is released at all of the synapses simultaneously and this leads to an action potential in the neuron.

A) What type of summation of PSPs is this? Why?

B) List the sequence of steps that occur starting from binding of glutamate to the glutamate-gated channels at the synapses and ending with the membrane potential at the axon hillock returning to resting potential at the end of the action potential. (Include all the changes in voltage-gated channels underlying the action potential.)

Typical anti-depressants create more of this neurotransmitter in the synapse to bind with postsynaptic neurons:

The famous silent screen actor, Charlie Chaplin, was sued for paternity in the 1920’s. His defense lawyers used his and the baby’s blood types to show Charlie could not have been the father. Explain how this could have been done considering the only tests that were available at that time where blood type, A, B, O and the Rhesus factor, + or -.

Verapamil is a drug that blocks Voltage-dependent Calcium channels. Would Verapamil be useful in treating tachycardia or bradycardia and why (must explain mechanism of action)?

Prosimians (lemurs, lorises, and tarsiers) use their sense of smell to find food, have a pronounced snout, are quadrupedal, and have a long tail used for balance. Apes have a flattened face, no tail, use their sight for finding food, and are quadrupedal. Humans are bipedal, use sight to find food, have a flattened face, and have no functional tail. Monkeys have a flattened face, use their eyesight to find food, are quadrupedal, and have a functional tail. If the prosimians condition is pleisiomorphic, draw a cladogram showing the phylogeny of primates. Include the synapomorphies as slashes on your cladogram in the appropriate places and which each one is.

All tissues change as a result of aging. Proper nutrition and good health can promote normal tissue functioning past middle age but can only do so much. As a result, anti aging skin products are huge industries in our country. Do you think that these creams/potions, etc., can really make a difference in fighting aging? Why or why not? What do you think about the article from Science Daily and the possibility of an anti-aging pill?
