31.3 The Peripheral Nervous System – We learned about the functions of the motor division of the peripheral nervous system. Impulses are transmitted from the central nervous system to muscles or glands through the peripheral nervous system. We discovered that the somatic nervous system regulates body activities that are under conscious control, such as moving our body. We discovered how rapid responses travel through a pathway known as a reflex arc.

31.3 The Peripheral Nervous System – We learned about the functions of the sensory division of the peripheral nervous system. We learned how messages travel between the central nervous system and the body. We learned the type and location of sensory receptors which respond to chemicals, light, touch, temperature, and injury.

31.2 The Central Nervous System – We learned the functions of the brain and spinal cord. We learned about the major structures of the brain, their functions, and how they interact with other brain structures. We learned how drugs change the brain and lead to addiction. We discovered that the spinal cord is the main communication link between the brain and the rest of the body.

We reviewed for a Test on Lesson 2 Interactions within Ecosystems. Then PJ took the Test on Lesson 2 Interactions within Ecosystems.

31.2 The Central Nervous System – We are beginning to understand that the human body is a complex system. The coordinated functions of the brain and spinal cord support life processes and maintain homeostasis. We discovered when and how it was discovered that the left and right hemispheres of the brain have separate functions.

31.1 The Neuron – We learned how a nerve impulse begins. We discovered the difference between a resting and moving impulse. Then we learned the function of the synapse the end of the neuron. We learned the neurotransmitters are chemicals that transmit an impulse across a synapse to another cell.
