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 ...

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 ...

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 ...

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 ...

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.

Schematic representation of axonal transport vesicles (blue) carrying presynaptic proteins (SV and AZ proteins). Kinesin motor proteins (KIF1A) attach these vesicles and carry them along the axons to ...

The flow of water within a muscle fiber may dictate how quickly muscle can contract, according to a University of Michigan study. Nearly all animals use muscle to move, and it's been known for a long ...

Proprioceptive neuromuscular facilitation (PNF) is a form of assisted stretching. It combines passive stretching with muscle contraction. First, your partner applies force to stretch your muscle ...

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, ...
