Divisions of the Nervous System Section 35-3

1. Using Playdough at your table, sculpt a model of the brain. 2. Be sure to include the following parts: - Frontal lobe -Parietal Lobe -Occipital Lobe - Temporal Lobe -Cerebellum -Medulla Oblongata 3. Draw lines in your model to represent folds in your brain. 4. Label each part of your brain using paper and toothpicks.

Medulla oblongata Frontal lobe Occipital lobe Temporal lobe Cerebellum Parietal lobe

Reflexes ► Reflex- a quick, automatic response to a stimulus  Processed in the spinal cord  Ex. Blinking, sneezing Animals use reflexes to avoid danger

Reflex Arc ► Sensory receptor  sensory neuron  motor neuron  effector ► Example: Stepping on a tack  Receptor- toe feeling the tack, causing pain, ctivating receptor  Sensory neuron- “pain” signal transmitted from receptor to motor neuron  Motor neuron- signals leg to pull away from the tack  Effector- leg muscles contract, foot is pulled away from the tack

Somatic vs. Autonomic ► Somatic nervous system- conscious control  Example: Moving your fingers, toes, mouth, etc ► Autonomic nervous system- unconscious control  Increasing heart rate and blood flow during exercise

Homework ► S.A  p. 905 #1-6
