A semaphorin code defines subpopulations of spinal motor neurons during mouse development.
In the spinal cord, motor neurons (MNs) with similar muscle targets and sensory inputs are grouped together into motor pools. To date, relatively little is known about the molecular mechanisms that control the establishment of pool-specific circuitry. Semaphorins, a large family of secreted and cell surface proteins, are important mediators of developmental processes such as axon guidance and cell migration. Here, we used mRNA in situ hybridization to study the expression patterns of semaphorins

NASA CONNECT Better Health from Space to Earth
In NASA CONNECT Better Health From Space to Earth, students will learn about the importance of good nutrition and exercise. They will investigate what we can learn in space about our bodies here on Earth. Students will see how researchers and scientists apply the mathematics concepts of measurement and estimation to study the loss of calcium in bones and the loss of muscle mass while astronauts are living and working in space.

1.3 Warm-up activities

A variety of actions might be included in warm-up activities, and there is good reason for keeping these simple and repetitive. If the brain and muscles have to concentrate on learning new and complex patterns of movement, then this takes attention away from raising the core body temperature by 1 or 2 degrees and increasing the heart rate enough to perspire.

Movements might include:

  • walks gradually increasing in speed to a small run;

Conversion Immersion: Working Together to Create Investigative Labs
A "Conversion Immersion" workshop was convened to provide a forum for instructors to work together to convert traditional "cookbook" laboratories to a more investigative format. This paper summarizes some of the ideas that emerged from the two sessions of the workshop, which included labs on the following topics: chick development, soils, antimicrobial agents, effects of pH and heavy metals on microbial processes, DNA isolation, immunohistochemistry, enzymes, osmosis, invertebrate diversity, pla

An Analysis of Bone/Muscle Movement
By manipulating a simple kinematic model representing the leg and foot, students can get hands on information about the interaction of bones and muscles in humans. Having worked with the model, they then are able to predict and analyze the properties of bone/muscle systems in other vertebrates and understand how these systems have become modified during the course of evolution for a particular life style. By the end of the exercise, students have learned both traditional information (cellular st

2.3.1 Applying the principles

Trying to use 'guiding principles' of this type does not make assessment straightforward. For example, such principles can't be rigidly applied in an abstract way, reflecting absolutes such as what is 'right' or 'wrong'; their operation depends on context.

We can explore this further by attempting to apply the third of these principles. Justice might be considered to involve directing the benefits of a new technology to those who need it most. At the same time, the role of policy makers

Muscles
This topic starts with a basic introduction to muscles and an image illustrating the possible locations of the different muscle tissues. The three types of muscle tissue are described in more detail. Along with the features of muscle tissue (e.g. contractibility), the functions of these tissues (e.g. support) are discussed.
