TRANSCRIPT
Pick up Chap 9 Overview of the Nervous System along with a textbook.
“Do Now”◦ Based on your current knowledge, describe the
nervous system in terms of structure and function.
Pick up worksheet and a textbook. “Do Now”
◦ Name at least three structures of a neuron:1. Dendrites2. Axon3. Myelin4. Nucleus5. Axon terminal bud
Pick up neuralville rubric along with a textbook.
“Do Now”◦ Describe the function of the following:
Dendrites Axon Terminal bud Myelin
Pick up “Mouse Party” worksheet. Turn in Nervous Tissue and Structure Lab
along with mad mad neuron worksheet from Tuesday if you haven’t done so.
“Do Now”◦ Describe the effect that drugs may have on the
function of a neuron?
Pick up blank paper and pom-pom question worksheet.
Turn in your Neuron Webquest. “Do Now” (on half sheet of paper). Write
your name and turn-in when completed.◦ Draw a motor neuron and label its parts.◦ Describe how information is received and passed
on to another neuron. Use the following terms: dendrites, axon, cell body, synaptic knob, impulse, synaptic cleft, neurotransmitters.
Pick up Reflex Arc worksheet along with a textbook.
Turn-in Neuronville cartoon “Do Now”
◦ Describe the events that occur during an action potential using the following terms: Sodium, potassium, sodium/potassium pump, ATP, axon.
2. Cell membrane is stimulated. Na+ channel opens, Na+ flows into channel, making cell positive – depolarization
3. In turn, this causes K+ channels to open
4. K+ flows out of cell – repolarization
5. Na+/K+ pump returns the Na+ and K+ back to resting potential
Resting Potential:1.Na+/K+ pump maintains polarization
Action Potential:
Pick up Parts of the Brain worksheet along with a textbook.
“Do Now”◦ Describe the major events that occur in the knee-
jerk reflex from striking the patellar ligament to the movement of quadricep femoris.
Pick up Sheep Brain Dissection worksheet Take out your parts and functions of the
nervous system packet “Do Now”
◦ Name the 4 lobes of the brain and their functions:
1. Frontal – reasoning, planning, speech, movement, emotions and problem solving
2. Parietal – perception of stimuli such as touch, pressure, temperature and pain
3. Temporal – perception and recognition of auditory stimuli (hearing) and memory (hippocampus)
4. Occipital – concerned with many aspects of vision
Pick up Nervous System Review & turn in rewrite paper along with original paper and rubric
“Do Now”◦ List at least 5 external and internal structures of the sheep brain:
Take out review sheet for test tomorrow. “Do Now”
◦ Label the following parts of the brain. DO NOT USE YOUR NOTES.
