Muscle fibers are the individual, elongated cells that make up muscle tissue; they are responsible for the contraction and movement of muscles. Muscle tissue, on the other hand, is a collection of these muscle fibers grouped together, functioning as a whole to perform specific actions. There are three types of muscle tissue in the body: skeletal, cardiac, and smooth, each with distinct functions and characteristics. In summary, muscle fibers are the building blocks, while muscle tissue is the collective structure formed by these fibers.
What else can I help you with?
What is sacrolemma?
The sarcolemma is the cell membrane of a muscle fiber. It surrounds and protects the muscle fiber and controls the movement of substances into and out of the cell. The sarcolemma plays a crucial role in muscle contraction and the transmission of nerve impulses to the muscle fiber.
What is connective tissue compose of?
cells, fiber, and extracellular matrix. Connective tissue is a huge part of tendons, ligaments, joints, and even muscle.
What are the units of contraction within a muscle fiber called?
The units of contraction within a muscle fiber are called sarcomeres. Sarcomeres are the basic functional and structural units of striated muscle tissue, composed of actin and myosin filaments. They are organized in a repeating pattern along the length of the muscle fiber, allowing for coordinated contraction and relaxation during muscle activity.
What is the name and location of three connective tissue layers of muscles?
There are only 3.The endomysium is the connective tissue that surrounds each muscle fiber (cell).The perimysium encircles a group of muscle fibers, forming a fascicle.The epimysium encircles all the fascicles to form a complete muscle.A tendon is a cordlike extension of the preceding three linings. It extends beyond the muscle tissue to connect the muscle to a bone or to other muscles.There are only 3.The endomysium is the connective tissue that surrounds each muscle fiber (cell).The perimysium encircles a group of muscle fibers, forming a fascicle.The epimysium encircles all the fascicles to form a complete muscle.A tendon is a cordlike extension of the preceding three linings.

What type of cell does a fiber have?
A fiber, particularly in the context of muscle tissue, is made up of muscle cells known as myocytes. In the context of connective tissue, fibers such as collagen and elastin are produced by fibroblasts, which are specialized cells responsible for synthesizing the extracellular matrix. In both cases, the specific type of fiber and its function are determined by the type of cells involved in its formation and maintenance.
What is the difference between sarcolemma and endomysium in muscle tissue structure?
The sarcolemma is the cell membrane of a muscle fiber, while the endomysium is the connective tissue that surrounds individual muscle fibers within a muscle.
What is the connective tissue covering called that encloses the sarcolemma of an individual muscle fiber?
The connective tissue covering that encloses the sarcolemma of an individual muscle fiber is called endomysium. It surrounds each muscle fiber and provides support and protection to the muscle cells.
What is the term for a Smaller fiber in a muscle fiber?
The smaller fiber in a muscle fiber is called a myofibril. A band of tissue that connects bone to bone is called a ligament.
Which structure would be very numerous in muscle tissue?
fiber
What tissue insulates each muscle fiber?
endomysium
What is the difference between endomysium and sarcolemma in muscle tissue structure?
The endomysium is a connective tissue layer that surrounds individual muscle fibers, while the sarcolemma is the cell membrane of a muscle fiber. The endomysium provides support and protection to the muscle fibers, while the sarcolemma controls the movement of substances in and out of the muscle cell.
What is the difference between endomysium and sarcolemma?
The endomysium is a connective tissue sheath that surrounds individual muscle fibers, providing support and elasticity. The sarcolemma, on the other hand, is the cell membrane of a muscle fiber, responsible for controlling the movement of substances in and out of the cell.
What is the name of the loose areole connective tissue covering of an individual muscle fiber?
The endomysium is the correct answer.Endomysium is the name of the fine connective tissue sheath that surrounds each individual muscle fiber.
What is the connective tissue memebrane that covers a muscle?
endomysium is the connective tissue that surrounds each muscle fiber. heres your answer!
Why is a muscle considered a tissue?
Muscle fiber (myofiber) is the cell, muscle tissue is the type of tissue, lots of muscle tissue and some connective tissue is a muscle organ, and those muscle organs are all parts of the muscle system. All have the same name but mean different types when it is clarified in to the anatomical units.
What is the percentage of muscle tissue?
A single muscle fiber may contain 15 billion thick filaments.
Explain the difference between the two types of skeletal muscle tissue?
Skeletal muscle tissue differs from cardiac tissue in that skeletal muscles are striated muscles that require conscious stimulation to act, and cardiac muscles are smooth and basically run "automatically".
