In an isotonic contraction the muscle does what?
Changes in length and moves the "load"
What structure runs the length of the sarcomere through the thick filaments and contributes to the elastic recoil in muscle?
titin
What monitors what comes in and out of the cell or nucleus?

Is Heart made up of striated or non striated muscles?
Heart muscle is striated but not in the same way that skeletal muscle is. Cardiac muscle is a type of involuntary striated muscle found only in the walls of the heart.Cardiac and skeletal muscle are similar in that both appear to be striated in that they contain sarcomeres. In striated muscle, such as skeletal and cardiac muscle, the actin and myosin filaments each have a specific and constant length on the order of a few micrometers, far less than the length of the elongated muscle cell (a few millimeters in the case of human skeletal muscle cells).The filaments are organized into repeated subunits along the length. These subunits are called sarcomeres. The sarcomeres are what give skeletal and cardiac muscles their striated appearance of narrow dark and light bands, because of the parallel arrangement of the actin and myosin filaments.However, cardiac muscle has unique features relative to skeletal muscle. For one, the myocytes are much shorter and are narrower than the skeletal muscle cells, being about 0.1 millimeters long and 0.02 millimeters wide .Furthermore, while skeletal muscles are arranged in regular, parallel bundles, cardiac muscle connects at branching, irregular angles.Anatomically, the muscle fibers are typically branched like a tree branch. In addition, cardiac muscle fibers connect to other cardiac muscle fibers through intercalcated discs and form the appearance of a syncytium (continuous cellular material).These intercalcated discs, which appear as irregularly-spaced dark bands between myocytes, are a unique and prominent feature of cardiac muscle .
How long is the longest muscle in your body and how long is it?
The longest muscle in the human body is the sartorius muscle, which extends from the hip to the inner side of the knee. It measures approximately 15-17 inches in length.
What monitors muscle length and sends an impulse to the spinal cord to initiate the stretch reflex?
What monitors muscle length and sends an impulse to the spinal cord to indicate the stretch reflex
What is muscle length?
muscle length is the length of an animal or humans muscle
Does muscle length change during isometric movements?
No, the length of the muscle fibers does not change. In isotonic movements is when the length changes.
What is a muscle cell?
A muscle cell is a cell which can change length
What type of receptor detects muscle length?
Muscle Spindle
What aspects of muscle function are monitored by muscle spindles and tendon organs?
Muscle spindle monitors stretch and golgi tendon organ the tension that developed during forced contraction thank u
Do muscle spindles measure the rate of stretch of a muscle?
They measure the rate of change of length of a muscle.
Why stretching a muscle beyond its optimal length reduce its ability to contract?
Stretching a muscle beyond its optimal length reduces its ability to contract. This is because the muscle can be torn or damaged.
What happens If a muscle is applied to a load that exceeds the muscle's maximum tension?
The muscle length will not change during a contraction.
When your muscle contacts what is happening to its length?
it shortens
What muscle do you use to sing?
You will use the diaphragm muscle to control the length/strength of your breath.
The muscle decreases in muscle length during contraction but tension is the same?
Isotonic contraction
