Nerve conduction in the skin

Information sheet:
A stimulus is received by a receptor and transmitted across the nerve cells to the brain.

The cells of the nervous system are introduced and the basic structure of a nerve cell is described. The process of transmitting a nerve impulse from the skin to the brain is explained based on saltatory conduction.
In addition, the different skin sensors are introduced:
· Free nerve endings
· Tactile corpuscles (Meissner?s corpuscles)
· Cold receptors (Krause?s corpuscles)
· Heat receptors (Ruffini?s corpuscles)
· Pressure receptors (Pacinian corpuscles)

C6 Skin and hygiene (teacher instructions)

Experimentation instructions for Experimento - 10+:
Background information on the content and practical information on conducting the experiment "Skin and hygiene - Why do we wash our hands?". This experiment comprises two subexperiments.


This is a typical introductory experiment to the topic of hygiene, as well as to the topics of solutions and emulsions. The experiment itself can deal only superficially with the topic in question. The teacher will have to provide more detailed information depending on the age group of the students. The materials supplied allow eight groups of students to conduct the experiments simultaneously.

The experiment comprises two subexperiments:
· What happens when you wash your hands?
· The pH value of skin

Notes:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
· All materials mentioned in the instructions will have to be purchased directly from commercial sources.

C5 What functions does the skin have? (teacher instructions)

Experimentation instructions for Experimento - 10+:
Background information on the content and practical information on conducting the experiment "What functions does the skin have? - The skin as a sense organ". This experiment comprises three subexperiments.


The suggested experiments can be carried out by up to eight groups of students. They are particularly suitable as an introduction to the sense of touch from a sensory-physiological point of view. These instructions provide notes for linking the experiments to the curriculum and ideas for further study.

The experiment comprises three subexperiments:
· How does skin react to touch?
· How does the skin perceive cold and heat?
· How does the skin distinguish between different temperatures?

Notes:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
· All materials mentioned in the instructions will have to be purchased directly from commercial sources.
