Document Summary

The central nervous system is composed of: the brain, spinal cord and peripheral nerves, the brain and the spinal cord, the brain and peripheral nerves, the spinal cord and peripheral nerves. A neuron itself had all of the following structures, except: soma, axon, dendrites, myelin sheath. The process that the inside of a neuron goes from a negatively charged resting membrane potential to a net positive charge is called: depolarization, repolarization, hyperpolarization, threshold. The chemical released from the axon terminal of a presynaptic neuron when receiving an action potential is called: synapse, synaptic knob, receptor, neurotransmitter. The nervous system which primarily helps the body cope with emergency situations is the: sympathetic nervous system, parasympathetic nervous system, efferent nervous system, afferent nervous system. The hypothalamus regulates the anterior pituitary gland functions by: secreting releasing and inhibiting factors, direct neural innervation, both 1 and 2, producing hormones and storing them in the anterior pituitary gland.
