What else can I help you with?
What kind of tissue does the heart have in it?
The heart is comprised of specialized cardiac muscle fibers.
What is a layer of the heart largely composed of cardiac muscle tissue?
This word can be broken down into two parts that will reveal the answer to your question. Myo is the medical term for muscle and cardio is the medical term for heart. Therefore, your answer would be the muscle that is the heart.
What maintains the tension in a muscle spindle?
The tension in a muscle spindle is maintained by intrafusal muscle fibers, which are specialized muscle fibers within the spindle that are innervated by sensory nerve fibers. These sensory fibers detect changes in muscle length and transmit signals to the central nervous system to regulate muscle tone and coordination.
What type of muscle fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.

What carries cardiac impulses to the myocardium?
Cardiac impulses are carried to the myocardium via specialized muscle cells called Purkinje fibers. These fibers are part of the cardiac conduction system and help to transmit electrical signals rapidly and efficiently throughout the heart muscle.
Which fibers in the skeletal muscle are stimulated only by the degree of stretch?
Muscle spindles are the fibers in skeletal muscles that are stimulated by the degree of stretch. These specialized sensory organs detect changes in muscle length and contribute to the stretch reflex, helping to maintain posture and control muscle contraction.
What are contractile fibers?
Contractile fibers are specialized muscle fibers responsible for the contraction and movement of muscles. They contain proteins like actin and myosin, which interact to produce force during muscle contraction. These fibers are found in various types of muscle tissue, including skeletal, cardiac, and smooth muscle, each serving distinct functions in the body. Their ability to contract and relax is essential for various bodily movements and functions.
Why are skeletal muscle fibers unusual?
The skeletal muscle, or striated muscle, is the muscle attached to the skeleton. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons. The contraction of skeletal muscle is under voluntary control.
What has a greater capacity to do anaerobic work and produce more overall force?
Skeletal muscle fibers have a greater capacity for anaerobic work and can produce more overall force compared to smooth and cardiac muscle fibers. This is due to the greater abundance of fast-twitch muscle fibers in skeletal muscles which are specialized for high-intensity, short-duration activities.
Smooth muscle fibers are the shortest of all muscle cell types?
No. Cardiac muscle fibers.
