14 September 2012 Homework #2 1) A) The parts to a gist prison cell be the cell body, bushy dendrite fibers, the axoneeees, and the bulb sheath. B) Neural neural momentums argon retortd when a neuron fires an longing called the action potential, which is a draft electrical charge that travels big money the axon. The first part of the axon begins the process by interruption up its gate, so that positively charged ions can gush through the cell membrane. As a result, this process depolarizes that axon section, causing other axon channel to open and wherefore the process repeats continuously later on the other. C) In call of communication, nerve cells communicate with one another by having the dendrites fill 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 neurot ransmitters 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 in the midst of 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 bring whether that neuron will generate a neural impulse or not. B) An agonist mimics neurotransmitters functions by binding to receptor sites and bea r on the sending neuron. C) An antagoni! st does the glacial of agonist. They bind to receptors and block neurotransmitter functioning. 3) A) the foursome lobes of the brain are the window dressing lobe, the parietal lobe, the occipital lobe, and the temporal lobe.
