on that's unable to produce and release neurotransmitters. C that neuron still have an action potential? Choose the answer with the correct answer and the e pau&isan correct reasoning. O No, action potentials need neurotransmitters to increase message speed O No, a neuron can't receive messages without its own neurotransmitters O No, a lack of neurotransmitters would leave a neuron unmyelinated O No, action potentials don't occur in the axon O Yes, action potentials don't require neurotransmitters

Human Movement

Humans can move from one place to another through coordinated movements and postures. The movement produced by the human body due to the contraction of muscles and bending of bone joints is called human movement. Human movements are controlled by the nervous system. Hence, the human movement incorporates the use of muscles, ligaments, joints, and bones.  Kinesiology is the field that deals with the study of human movements.
