This is a microscopic image of two nerve-muscle synapses in a mouse model of a human motor neuron disease (amyotrophic lateral sclerosis, ALS) in which nerve-muscle contacts break. Energy-producing ...

Muscle contraction is the tightening, shortening, or lengthening of muscles when you do some activity. It can happen when you hold or pick up something, or when you stretch or exercise with weights.

Using powerful new visualization technologies, researchers have captured the first 3-D images of the structure of a key muscle receptor, providing new insights on how muscles develop across the animal ...

The neuromuscular junction - where nerves and muscle fibers meet - is an essential synapse for muscle contraction and movement. Improper function of these junctions can lead to the development of ...

The connections between the nervous system and muscles develop differently across the kingdom of life. It takes newborn humans roughly a year to develop the proper muscular systems that support the ...

Your brain is not bolted in place. It floats in a thin bath of cerebrospinal fluid, and every time you take a step, your ...

Every time you brace your abs to lift a grocery bag, hold a plank, or even laugh hard enough to double over, a pressure wave ...

When labor begins, the uterus must coordinate rhythmic, well-timed contractions to deliver the baby safely. While hormones such as progesterone and oxytocin are key contributors to that process, ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a new study. The flow of water within a muscle fiber may dictate how quickly muscle can contract, ...

Cognitive pressure disrupts muscle control and blood flow, highlighting its role in physical performance during low-intensity ...
