Nerves & Neurons

Structure of a myelinated Neuron Create-Your-Own Neuron · Using the Playdough, create two synapsing neurons · Be sure to include the following structures: · Cell Body · Dendrites · Axon · Axon Terminal · Myelin

Neuromuscular Junction Neuromuscular Junction (animation) Excitatory & Inhibitory Neurotransmitters

Lethal Injection / Euthanasia How does it work? · Sodium thiopentol is an anesthetic used to induce medical comas · · Pavulon blocks acetylcholine receptors in neuromuscular junctions (arrests breathing) · · Potassium chloride - hyperpolarizes neurons of the heart.

3 Which of the following is incorrect? A The central nervous system integrates and processes information sent by nerves. B The autonomic system controls digestive system secretions and the functioning of smooth and cardiac mucles. C The somatic system consists of sensory receptors, nerves that carry sensory information to the CNS. D The peripheral nervous system consists of the brain and the spinal cord.
