Which of the following can be a danger of polycythemia?

What does the cardiovascular system refer to?

Which blood vessels control the flow into capillary beds?

Which of the following are classified as granulocytes?

Neurons with their conductile regions in the decussation of the pyramids have their input regions in the:

There are cells in the central nervous system that contain proteins that remove glutamate from the extracellular space. Where would you expect to find these proteins predominately located?

In the central nervous system, an action potential would likely be generated at the trigger zone by:

(10 points) Tetanus toxin enters the output regions of motor neurons by endocytosis. The resulting vesicles are transported toward the neuronal cell body on by the end directed motor protein, called . When the vesicle reaches the motor neuron cell body, it is released from this neuron by exocytosis and taken up by endocytosis into inhibitory interneurons. In these interneurons, tetanus toxin destroys VAMP (synaptobrevin), which has alpha helices that span the membrane of . The destruction of VAMP prevents it from winding together with the transmembrane protein and the membrane-associated protein to form the complex. This prevents release of neurotransmitter from the output region of this interneuron and ultimately prevents the opening of channels (be specific for ion type) in the postsynaptic cell. Despite the destruction of VAMP, Ca2+ still enters the cell through calcium channels and binds to on the vesicle membrane.

Which cell type would you expect to have the most active lipid synthesis in the centralnervous system?

Guillain Berré syndrome is a demyelinatig disease in the peripheral nervous system. You would expect the cell type affected by this disease to be:
