What else can I help you with?
Which cells have long fibers that can contract and relax?
Muscle cells can contract and relax and lave fibers as long as 1.5 feet.
What cells have fibers that can contract and relax?
Muscle cells have fibers that can contract and relax. These fibers, known as myofibrils, contain the proteins actin and myosin that allow them to slide past each other and generate force. This contraction and relaxation of muscle fibers enable movement in the body.
Muscle fibers contract and relax in response to what?
nerve impulses
Which of these are tissues that can relax and contract?
Smooth muscle tissues can relax and contract. Additionally, cardiac muscle tissues also have the ability to relax and contract. Skeletal muscle tissues are another type that can relax and contract voluntarily.
Which cell in human body contract and relax?
Muscle cells
What is the type of tissue made of cells the contract and relax to produce movement?
Tissue made of cells that contract and relax to produce movement is called muscle tissue.
Tissue has elongated cells that shorten and cause movement?
Muscle tissue is made up of elongated cells called muscle fibers that can contract and relax to produce movement. These muscle fibers contain specialized proteins that allow them to shorten and generate force, leading to various types of movements in the body.
What usually triggers muscle fibers to contract or relax?
The contraction is triggered by the release of calcium within the muscle which is triggered by an electrical signal from a nerve.
What is an example of a tissue in your body?
One example of a tissue in the human body is muscle tissue, which is responsible for body movement and generating force. Muscle tissue is composed of muscle fibers that contract and relax to produce motion.
Interesting muscle cell facts?
Muscle cells, or muscle fibers, are unique in that they are multi-nucleated, containing several nuclei. They contract and relax to generate force and movement in the body. Muscle cells also have specialized structures called sarcomeres, which are responsible for muscle contraction.
Are there fibers in the esophagus?
Yes, the esophagus is lined with a layer of smooth muscle fibers that help transport food from the mouth to the stomach through a process known as peristalsis. These muscle fibers contract and relax to push food downward.
What are tissue made up of interconnected elongated cells that contract and relax called?
Tissues made up of interconnected elongated cells that contract and relax are called muscle tissues. These cells are specialized for generating force through the contraction and relaxation process, allowing movement in the body. Examples include skeletal, smooth, and cardiac muscle tissue.
