The following site provides information regarding the nervous system's control of muscle tension.

Students learn about the classes of pharmaceuticals that interact with the autonomic nervous system, and then relate the consequences of nicotine abuse with respect to autonomic control of the cardiovascular system.

Students learn to identify the type of cells that make up nervous tissue.

The parts of the brain and the anatomy of the nervous system and how they function are explained. An interactive diagram shows the location of various parts of the brain from three different perspectives, and summarizes what each does....

Find out about the major sections of the neurological exam and the connection between location and function in the nervous system. Also learn the benefit of a rapid assessment for neurological function in a clinical setting.

Describe the structures found in the peripheral nervous system and the functions of those parts in the human body.

Describes the organization and function of the nervous system.

Students study the adult brain, and learn the connections between the cerebrum and brain stem through the diencephalon, and from those regions into the spinal cord.

Nervous system signals are transmitted electrically along individual neurons, but neurons are separated from each other by a tiny gap. Chemical messengers called neurotransmitters cross the gap between neurons. Neurotransmitters fit into...

Messages within the brain and the rest of the nervous system are sent very rapidly. These messages are conducted by cells called neurons. Neurons are specialized to receive and transmit message and neurons are connected in networks. In...

Class notes on The Nervous System - Spinal Cord and Peripheral Nerves.

This website from the University of Washington is divided into three sections: "History of Cocaine," "Effects of Cocaine on the Nervous System," and "The Brain on Cocaine." Read interesting facts about the use of cocaine before it became...

Students learn how the different stages of embryonic development relate to the adult structures of the central nervous system, and understand the growth and differentiation of the neural tube.

Prepare for the MCAT by reading this passage and answering questions based on the given table about how different viral doses affect behavioral or electrical abnormalities in mice.

When you breathe, you transport oxygen to the body's cells to keep them working, while also clearing your system of the carbon dioxide that this work generates. How do we accomplish this crucial and complex task without even thinking...

This site from AquaScope talks about how big a whelk can get, the color, how they move, where the digestive and nervous systems are found.

A broad overview of the mammalian endocrine system. Lists the major glands and the function of each. Includes a list of abbreviations and their meanings frequently found in high-level endocrine literature.

In this lesson on the brain's neural networks, students investigate the structure and function of the neuron. They discover ways in which engineers apply this knowledge to the development of devices that can activate neurons. Includes...

Nervous system messages are sent as electrical signals along the length of axons and dissolved salts are important for electrical signaling in cells. In this lesson students are introduced to this concept by creating an electrical...

Build nerve cell models in cooperative groups, and articulate the structure and function of nerve cells to explore the nervous system. Describe specific elements of human physiology by "advertising" the nervous system in nerve cell...

This lesson describes the function and components of the human nervous system. It helps young scholars understand the purpose of our brain, spinal cord, nerves and the five senses. How the nervous system is affected during spaceflight is...

Throughout the day, your nervous system monitors and makes endless adjustments to your body's basic systems--all to keep you alive. This interactive feature illustrates the complexity of such a task.

This article gives examples of how it looks when a child is experiencing sensory processing issues and gives tips on how to provide a sensory diet to "nourish" a child's nervous system. The examples and tips are categorized into groups...

Describes anatomical features of a spider, including its external structure, eyes, mouth parts, digestive system, circulatory system, respiratory system, nervous system, reproductive system, and its spinnerets.
