27.3 SCIENCE - LIFE SCIENCE (V,VI,VII)

27.3.6.5.21 -- Students will describe the structure and function of the human senses and the signals they perceive.



How does the nervous system maintain body homeostasis with electrical signals, provide for sensation, higher mental functioning and emotional response, and activate muscles and glands?

What are the divisions of the nervous system and their components?

How does the structure of the neuron relate to its role in nerve transmission?
How are reflex arcs used to maintain homeostasis?
How do nerve impulses travel down a neuron and how is the nerve impulse transmitted to other cells?
What are the responsibilities of major structures of the brain?
What occurs in the brain during the following devlopemental stages: newborn, adolescence and old age?
What are the causes and consquences of various cerebral and spinal pathologies?




1. The neuron, nerve impulse, and synapse
2. The central nervous system: brain and spinal cord
3. The peripheral nervous system
4. The senses
5. The effects of phychoactive drugs on the brain, addiction
6. The adolescent brain, the aging brain




Students will develop the ability to:
1. Describe a nerve and explain its job
2. Locate and describe the role of the following parts of a neuron: dendrite, axon, cell body, myelin sheath, node of Ranvier, axon terminal
3. Sequence the event and explain the process of a nerve impulse, including a description of the ion distributions and membrane potential of a neuron at rest, with an action potential, and during refractory period
4. Explain the process of a synaptic transmission of a nerve impulse, including the role of neurotransmitters
5. Describe the function of the central nervous system: brain and spinal cord
6. Describe the function and locate major parts of the brain: olfactory bulb, corpus collosum, cerebellum, medulla oblongat, thalamus, hypthalamus, cerebrum (cerebral cortex: occipital, frontal, parietal, temporal lobes)
7. Distinguish between white matter and gray matter
8. Sequence the events of a spinal reflex arc and describe its importance
9. Explain the reasoning for teenage risk taking and angst
10. Explain how to prevent memory loss and aging of the brain
11. Explain how the brain and spinal cord are protected by bone, meninges, cerebrospinal fluid
12. Organize the divisions of the nervous system and list the role and organs of each
13. Locate and explain the function and major structure of the eye and relate these structures to common eye disorders
14. Locate and explain the function of the major structure of the ear
15. Explain how the following psychoactive drugs interfere with normal synaptic transmission and produce reward: cocaine, alcohol, ecstasy, caffeine
16. Describe the relationship between drug abuse, tolerance, and drug addiction
17. Explain why drug addiction is considered a disease and how it is treated



1. Diagrams and models of brain, spinal cord, eye, and ear
2. Dissection of sheep brain and sheep eye
3. Laboratory distinguishing between reflex and reaction and measuring reaction time between classmates



1. Objective/subjective testing
2. Laboratory: sheep brain dissection, observing nervous response (reflex vs. reaction), sheep eye dissection
3. Class discussion



1. Viewing of 'Lorenzo's Oil'
