6.5 Neuron Structure and Function/Homeostasis
Crash Course - Nervous System/Homeostasis
Terminology Auction - prepare flash cards for each of the following terms - include term and group #.
Follow along with the video and raise the appropriate card at the appropriate time - occasionally, there are 2 cards involved coincidentally and occasionally, the terms are appropriate, but are not actually spoken in the text of the narration!
CENTRAL VS PERIPHERAL
AFFERENT VS EFFERENT
SOMATIC VS AUTONOMIC
SYMPATHETIC VS PARASYMPATHETIC
DENDRITE
AXON
MYELIN
NODES
SYNAPSE
HOMEOSTASIS
RESTING POTENTIAL
DEPOLARIZATION
REPOLARIZATION
ACTION POTENTIAL
Na-K PUMP
Na CHANNELS
K CHANNELS
MEMBRANE POTENTIAL
THRESHOLD
NEUROTRANSMITTERS

A MORE DETAILED IMAGE OF A NEURON -
Lots of diagrams and electron micrographs of these cells available. This one tries to hybridize the two media. |
This is the man with the beautiful name...Louis-Antoine Ranvier, who discovered the nodes in 1878.

Transmission through a neuron - Mechanism for Function
It's hard to show the mechanism of neural activity in a static picture, but this activity shows the interactions and allows you to pause and study the individual steps. Make sure you can explain the change in membrane potential with time.
|
what does the myelin sheath actually do?
What is the difference in the two types of conduction? How does this connect to (1) demyelinating diseases, like MS? to (2) the requirement that infants drink high fat content milk?

watch this animation through to the end and do the learning exercises.
This is a great place to make the connection between with the structure and function of the neuron and learning!
use the following materials to make your own model of a neuron pathway
dominoes
mouse traps
small balls of various materials - pingping, soft plastic, pompoms
Evaluate the accuracy of your model - where is it a good representation, where does it fall short?
