Coordinated activity to act as a pump?
cardiac muscle
What is a mass of interconnected cardiac muscle cells that act together as a group?
This is known as a cardiac syncytium, where adjacent cardiac muscle cells are interconnected by gap junctions, allowing them to function as a coordinated unit. This enables the heart to contract efficiently and effectively pump blood throughout the body.
What do not act as a stimulus to initiate a muscle contraction a. hormonal activity b. neurotransmitters c. a change in the pH of a muscle d. a change of temperature?
d.
What structure is found in cardiac muscle tissue but not skeletal muscle tissue?
Intercalated discs are unique to cardiac muscle tissue, providing a strong connection between adjacent cells and allowing for coordinated contraction of the heart. Skeletal muscle tissue lacks intercalated discs since individual muscle fibers act independently.
Why do muscles need to act as antagonistic pairs?
Muscles need to act as antagonistic pairs to create movement at a joint. One muscle contracts (agonist) to produce the desired movement, while the opposing muscle relaxes (antagonist) to allow the movement to occur smoothly and efficiently. This coordinated action helps stabilize the joint and prevent injury.
Why did Truman want to pass the National Security Act of 1947?
Truman wanted to pass the National Security Act of 1947 because he wanted the military branches to be better coordinated.
Do muscle act on surrounding fat?
no muscle not act on surrounding fat. muscle act on moving. fat accquired from laziness. laziness=muscle not acting. Studies have shown that muscle do in fact act upon its surrounding fat. Muscle that has been developed allow a 12% increase for the surrounding fat to become muscle! Muscle act as an inner furnace for your body and burns your fat as well throughout the day! That's why people with more muscle need to eat more often.
What is the act of swallowing known as?
The act of swallowing is known as deglutition. It involves a complex process where food or liquid is moved from the mouth through the pharynx and esophagus to the stomach. This process is crucial for digestion and is regulated by a series of coordinated muscle contractions. Deglutition can be divided into three phases: oral, pharyngeal, and esophageal.
Are the muscle in the chicken wing antagonist?
Yes, the muscles in a chicken wing can act as antagonists. In a typical chicken wing, the biceps (flexor) and triceps (extensor) muscles work in opposition to each other. When one muscle contracts to bend the wing, the other relaxes, allowing for smooth movement. This antagonistic action is essential for coordinated wing motion.
How can a prime mover also be consider a antagonist?
A prime mover, or agonist, is the primary muscle responsible for a specific movement, while an antagonist opposes that movement. In certain contexts, a muscle can act as both a prime mover and an antagonist, depending on the movement being performed. For instance, during a bicep curl, the biceps are the prime movers for elbow flexion, but they can also act as antagonists when extending the elbow, helping to control the movement and stabilize the joint. This dual role is essential for coordinated and smooth muscle function during dynamic activities.
Do smooth or skeletal muscle form a functional syncytium?
Smooth muscle forms a functional syncytium due to the presence of gap junctions that allow electrical signals to pass from one cell to the next, enabling coordinated contractions. Skeletal muscle, on the other hand, does not form a functional syncytium as each skeletal muscle cell (fiber) is innervated individually by a motor neuron and must be stimulated independently.
