14 September 2012 Homework #2 1) A) The parts to a gist carrel be the cell body, bushy dendrite fibers, the axonees, and the bulb sheath. B) Neural neural likings argon retortd when a neuron fires an pulsation called the action potential, which is a draft electrical charge that travels discomfit the axon. The first part of the axon begins the process by inauguration up its gate, so that positively charged ions can pig out through the cell membrane. As a result, this process depolarizes that axon section, causing other axon channel to open and so the process repeats continuously later on the other. C) In name of communication, nerve cells communicate with one another by having the dendrites happen the messages from other cells. The dendrites job is to receive nurture and conduct it toward the cell body. Next, they send a neural impulse down the axon to the ter bital branches of the axon, which then causes neurotransmitters to release in the synapse. These neurotransmitters attach themselves to the receptor sites of receiving neurons. 2) A) Neurotransmitters are chemical messages that cross the synaptic gap betwixt neurons. In other words, neurotransmitters are the messages that nerve cells send out, and they cross the gaps between separately of the cells. When released by the send neuron, neurotransmitters travel across the synapse and neuron. Therefore, they deflect whether that neuron will generate a neural impulse or not. B) An agonist mimics neurotransmitters functions by binding to receptor sites and impact the sending neuron. C) An antagonist does the glacial of agonist. They bind to receptors and block neurotransmitter functioning. 3) A) the intravenous feeding lobes of the brain are the window dressing lobe, the parietal lobe, the occipital lobe, and the temporal lobe. B) One function of each would be: The anterior lobe is involved in speaking and min muscle movement s. The parietal lobe receives sensory input ! for the sense of touch.
