Which organ system communicates with cells in muscle tissue so that the muscles contract or relax allowing the body to move which human body system?
The nervous system communicates with muscle tissue to control contraction and relaxation, enabling movement in the body. It sends signals through motor neurons that stimulate muscle fibers, facilitating voluntary and involuntary movements. This coordination is essential for activities ranging from walking to reflex actions.

What are the smooth muscle fibers called that support the lens?
The smooth muscle fibers that support the lens in the eye are called ciliary muscles. These muscles contract and relax to change the shape of the lens, allowing for accommodation and focusing on objects at different distances.
What happens after the electricity reaches the muscles?
After electricity reaches the muscles, it triggers the release of calcium ions within the muscle fibers. This causes the muscle fibers to contract and generate force, allowing movement to occur.
What type of nerve stimulates muscle cells to contract?
Somatic type of nerves stimulate the muscle cells to contract.
What muscle close a fist?
The muscles responsible for closing the fist are the flexor muscles located in the forearm. They include the flexor digitorum superficialis, flexor digitorum profundus, and flexor pollicis longus muscles. When these muscles contract, they pull on the tendons attached to the fingers and thumb, allowing the hand to make a fist.
Why do muscles bulged when they contract?
Skeletal muscle tissue is made of many fibers, which have many sarcomeres with overlapping actin and myosin protein strands. When muscles contract their proteins overlap eachother and shorten the fiber, which then increases height but shortens in length of each fiber.
What does acetycholine do to muscles?
Acetylcholine acts to excite skeletal muscles, allowing for the muscle to contract. It also serves to allow contractions in the smooth muscles, while slowing down the cardiac muscles
What muscle can do?
Muscles can contract and shorten
What happens to muscles when they contract?
When muscles contract, they shorten and generate force, allowing movement to occur. This process is controlled by the nervous system and involves the sliding of protein filaments within the muscle fibers.
What is the tissue that can move itself?
Muscle tissue is the type of tissue that can move itself. This is because muscles have the ability to contract and relax, allowing for movement in the body.
The iris of the eye has two main types of muscles. Name these two muscles and how they affect the pupil.?
The iris of the eye has two main types of muscles - the radial muscle and the sphincter muscle. The radial muscle lies on the outside of the iris, and the sphincter muscle surrounds the pupil, allowing it to dilate and contract.
Why do muscles shorten when they contract?
Muscles shorten when they contract because the muscle fibers within the muscle bundle slide past each other, causing the muscle to contract and pull on the attached bones, resulting in movement.
What muscle such as the heart muscle does its job without thinking about it?
Involuntary muscles contract subconsciously.
What are the smooth muscle fibers called that support the lens?
The smooth muscle fibers that support the lens in the eye are called ciliary muscles. These muscles contract and relax to change the shape of the lens, allowing for accommodation and focusing on objects at different distances.
What happens after the electricity reaches the muscles?
After electricity reaches the muscles, it triggers the release of calcium ions within the muscle fibers. This causes the muscle fibers to contract and generate force, allowing movement to occur.
Which tissue allow the body to move by stretching and contracting?
Muscle tissue is responsible for allowing the body to move by stretching and contracting. Muscles are made up of muscle fibers that can shorten (contract) and lengthen (stretch) to produce movement. Skeletal muscles, smooth muscles, and cardiac muscles are the three main types of muscle tissue in the body.
What are tissues that contract or relax to create movement?
Muscles are tissues that contract or relax to create movement in the body. They work by contracting to shorten and generate force, allowing the body to move and perform various functions. Smooth muscles, cardiac muscles, and skeletal muscles are the three types of muscle tissues in the human body.
How many sets of muscles in earth worm?
Earthworms have two main sets of muscles: circular and longitudinal muscles. The circular muscles contract to elongate the body, while the longitudinal muscles contract to shorten it, allowing the worm to move through the soil effectively. This coordinated muscle action enables earthworms to burrow and navigate their environment efficiently.
