  1. Aim: How does the nervous system communicate with other body systems? HW 16 Text chapter 35 Pg 897 vocabulary Pg 900 Q#1 to 4

  2. Nucleus Axon terminals Cell body Myelin sheath Axon Nodes Dendrites A Neuron Neuron Structure  Function Section 35-2

  3. Neuron to Neuron communication

  4. Figure 35-7 An Impulse Nerve Impulse Section 35-2 Action Potential As the action potential passes, potassium gates open, allowing K+ ions to flow out. At rest. Action Potential Action Potential The action potential continues to move along the axon in the direction of the nerve impulse. At the leading edge of the impulse, the sodium gates open. The membrane becomes more permeable to Na+ ions and an action potential occurs.

  5. Figure 35-8 The Synapse The Synapse When an impulse reaches the end of one neuron, neurotransmitters are released into the synaptic cleft Section 35-2 Direction of Impulse Dendrite of adjacent neuron Axon Receptor Vesicle Axon terminal Synaptic cleft Neurotransmitter

  6. Cerebrum Thalamus Pineal gland Hypothalamus Cerebellum Pituitary gland Pons Medulla oblongata Spinal cord Figure 35-9 The Brain Central Nervous System – Brain and Spinal Cord

  7. Interneuron (relay neuron): Relays message from sensory neuron to motor neuron Make up the brain and spinal cord

  8. Gray matter Central canal Spinal nerve White matter Meninges Figure 35-11 The Spinal Cord Spinal Cord Section 35-3

  9. Figure 35-2 Human Organ Systems Part 2 In what ways does the nervous system interact with the other systems below ? Section 35-1 Respiratory System Digestive System Excretory System Reproductive System Endocrine System Lymphatic System

  10. Autonomic Nervous System Controls the functions of the body that are not under conscious control
