Are you a Biology teacher introducing your high school students to Neurophysiology Functions of Neurons (Part 1)? Notes and examples are included. You can also easily convert this to a Google Slides lesson by dragging it into your Google Drive.

What is included?

✦ 48 total slides for notes and examples.

Throughout the Lesson, students will be introduced to the following:
✦ Explain the statement a cell membrane is said to be polarized

✦ Define resting potential

✦ Identify the causes of resting potential

• ✦ Unequal distribution of ions
• ✦ Differential permeability

✦ Explain how the RP is maintained

✦ Identify the function of Na+/K+ pump and that it is active

✦ Explain the experimental verification (involving DNP)

✦ Differentiate between a stimulation and excitation

✦ Identify the oscilloscope record during transmission of nervous message across a specific point

• ✦ Name the record & its the different phases

✦ Explain, during each phase, the variation in

• ✦ Membrane permeability
• ✦ Membrane polarity

✦ Differentiate between

• ✦ Voltage gated
• ✦ Chemical gated
• ✦ Non-gated channels

✦ Specify the opened and closed channels during each phase

✦ Identify the characteristics of nerve fiber

• ✦ Nerve fiber has threshold of excitation
• ✦ Only when change in the Pd that reaches threshold of excitation -50mV propagates
• ✦ Nerve fiber obeys the law of all or none

✦ Detection of cardiac activity.

✦ Identify the characteristics of nerve impulse

• ✦ Only APs propagate
• ✦ Constant speed

✦ Calculate the speed of propagation of nervous message.

✦ Explain the structure of a nerve.

✦ Explain the factors that affect the speed of propagation of nervous message along a nerve fiber

• ✦ Nature of neurons (being myelinated or not)
• ✦ Temperature
• ✦ Diameter of nerve fibers

✦ Explain how a nervous message propagates.

✦ Explain refractory period.

✦ Differentiate between the transmission of message along myelinated (salutatory movement) and non-myelinated fibers.
