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

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.

This site, created by a biology professor at Eastern Kentucky University, provides an overview of the brain and nerve senses of the bird.

A full-length download of the biotech magazine which discusses diseases of the central nervous system. It also takes a closer look at a sample of the tools and technology scientists use to address the various ways your brain and spinal...

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...

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.

Students learn the pathways that sensory systems follow into the central nervous system, and understand the difference between the two major ascending pathways in the spinal cord.

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 instructional activity students are introduced to this concept by creating an...

Students understand the relationship of mental status exam results to cerebral functions in the cerebral cortex.

Students will learn the components of the membrane that establish the resting membrane potential, and find out the changes that occur to the membrane that result in the action potential.

Students conduct an experiment to determine whether or not the sense of smell is important to being able to recognize foods by taste. They do this by attempting to identify several different foods that have similar textures. For some of...

For 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...

Brain cells called neurons send information and instructions throughout the brain and body. The information is sent via electro-chemical signals known as action potentials that travel down the length of the neuron. These neurons are then...
