1] Describe the structure of a typical neuron. Include a BRIEF description of the function of the main structural components of the nerve cell.
A] Consider the mechanisms by which this cell has become responsive to the âstimulusâ and how the neuron cause change in the next cell.
B] Given that one usually considers striated muscles as being organized in opposing pairs about the elements of the skeletal system (a bone is moved in one direction by one muscle and in the opposite by an opposing muscle), discuss the mechanisms that accomplish the integration of the functioning of the nerves responsible for the movement of a bone.
2] Explain how the three types of muscle cell evolved (specialized) from a stem cell type(myocyte) that interact with other cells(such as neurocytes, endothelial cells, myocytes, chondrocytes and osteocytes.) Include in this discussion concepts such as the structure of the three types of muscle cells. How does the structure of the cell relate to or account for
A] The type of synapse with the neuron or other cells?
B] The functional significance of unidirectional information in these three types of cell?
C] The particular role of that type of cell in homeostasis?
3] Discuss the concept that the nerve cell evolved from a cell that interacted with other cells using electrical synapse into the neuron that conveys specific unidirectional information that can be used to regulate other cells. Approach this discussion from the perspective of the processes that are responsible for the facilitating and inhibiting input that regulate the function of the cardiac pacemaker.
Include:
A) the mechanisms by which this regulation is transduced in the post synaptic membrane and how this affects the components of the movement of blood by the heart.
B) consider how the stimuli associated with homeostasis(pressure, pH, heart rate) are transduced into changes in the output of the heart to insure O2/CO2 homeostasis at the level of individual cells?
