- Explain the following mechanisms: 1. list three ways in which action potential can be initiated in neurons. 2.list the major classes of neurotransmitters and give examples of each . 3. list the functions of the hypothalamus and discuss how they relate to homeostatic control.The spinal cord has the motor neurons that control muscle. But who controls those motor neurons? Neurons in the motor cortex control them. There are also other groups of neurons that can command spinal motoneurons. For example, when it comes to controlling our balance and posture, cells from Ventricular Nucleus descend onto spinal motoneurons to control them. They form a tract within the ventromedial pathway called vestibulospinal trackThe morphological difference between bipolar neurons and unipolar neurons is_ and that determines how they are classified. a. the type of neurotransmitter they contain b. one is a Golgi Type I and the other is a Golgi Type II c. the number of axons that they have d. the number of different types of neurotransmitters they contain e. none of the above
