What else can I help you with?
The combining of a series of twitches to produce a sustained contraction is called?
summation
What employs a parallel after discharge circuit to produce sustained muscle contraction?
a oscillating circuit
How does the contraction of the I band contribute to the overall function of skeletal muscle?
The contraction of the I band in skeletal muscle helps to shorten the muscle fibers, allowing for movement and muscle contraction. This contributes to the overall function of skeletal muscle by enabling the muscle to generate force and produce movement.
A skeletal muscle fiber contains many nuclei?
Skeletal muscle fibers contain numerous nuclei. This is used to produce large amounts of the enzymes and structural proteins needed for muscle contraction.
What do muscles produce?
Muscles provide movement, especially the skeletal muscles. The smooth muscles in our organs produce movement called peristalsis or tonic contraction which holds sphincters closed.
What is commonly used to produce ATP during skeletal muscle contraction?
creatine phosphate, anaerobic cellular respiration, aerobic cellular respiration
What is the advantage of having multiple nuclei in one skeletal muscle cell?
the ability to produce large amounts of the enzymes and structural proteins needed for contraction
Does a skeletal muscle fiber contain many nuclei?
Yes, skeletal muscle fibers are multinucleated, containing multiple nuclei located along the length of the fiber. These nuclei are important for controlling protein synthesis and other cellular activities involved in muscle function and repair.
Does a liagament indirectly attaches skeletal muscle to bone?
Yes, ligaments do not attach skeletal muscles directly to bones. Ligaments are fibrous connective tissue that connects bones to bones, while tendons are the structures that attach skeletal muscle to bone. Tendons transmit the force from muscle contraction to the bone to produce movement.
What does preganglionic sympathetic Stimulation produce?
ACH
How does fusion frequency relate to tetanus?
The fusion frequency is the minimum stimulus required to elicit tetanus in a muscle. For example, the fusion frequency can be given in terms of volts (V), or it can be given in terms of whatever units by which the applied stimuli are being measured.
What is an example to illustrate anatomy vs physiology?
A good example to illustrate the relationship between anatomy and physiology is the relationship between how a skeletal muscle is structured (anatomy) and how it works (physiology) to produce a muscle contraction. Skeletal muscles are organized into units called sarcomeres which are overlapping chains of two different proteins, actin and myosin. That in a nutshell is the microscopic anatomy of skeletal muscle. Physiologically how it works is that the myosin heads latch onto the actin chain pulling it into the center of the sarcomere shortening it which causes the contraction.
