Following ingestion, the digestive system engages in a choreographed dance of mixing and movement. Peristalsis, the alternating waves of muscle contraction and relaxation, propels the food through the digestive tract. This powerful process ensures the continuous movement of food, facilitating both propuls...

When you breathe out, or exhale, your diaphragm and rib muscles relax, reducing the space in the chest cavity. As the chest cavity gets smaller, your lungs deflate, similar to releasing of air from a balloon. What are the steps of expiration? Terms in this set (5) Respiration center in...
What are two mechanisms to increase the strength of a muscle contraction? What action does the orbicularis oris allow the body to do? What is the action of the prime mover muscles in a deadlift (the plane of action)? What are the actions of the muscles of th...

Let’s describe muscle contraction in the context ofexerciseand other kinds of voluntary movements. With pushups, the triceps engage and shorten as you push your body away from the floor. The name for this type of muscle movement is concentric contraction. In contrast, your triceps will tense...
Skeletal muscles are how the body moves and functions. The activation of muscles is controlled by the brain sending nerve impulses to the neuromuscular junction (where the nerve touches the muscle) and this impulse tells the muscle to contract or r...
Be careful not to confuse muscle soreness with two other kinds of muscle pain:cramp(a sudden, intense but temporary contraction) andcontracture(persistent contraction of the muscles). What can you do to relieve sore muscles? Now we’ve established what causes muscle soreness, we can explore some...
That force can be applied by contraction of the muscle itself (active strain), or imposed on it by a stretch (passive strain), but there’s no practical difference between those scenarios. There are other kinds of muscle injuries, and a surprising amount of confusion, even among professionals...
