What is the difference between muscles that have a parallel arrangement of a Pennate arrangement?
Pennate. Unlike in parallel muscles, fibers in pennate muscles are at an angle to the force-generating axis (pennation angle) and usually insert into a central tendon. The force produced by pennate muscles is greater than the force produced by parallel muscles.
Are parallel muscles strong?
In the thigh, the hamstring and other flexor muscles have fibers that run parallel to the long axis of the muscle. Thus, if two muscles were of equal cross-sectional area, a pennate muscle would be stronger than a parallel fibered one because of its larger physiological cross-sectional area.
Which is the most common muscle fiber arrangement?
Key Takeaways
- Parallel muscles are the most abundant and typical, with fascicles arranged parallel to one another.
- Convergent muscles are similar to parallel muscles in attachment, although fascicles do not run parallel to one another, producing a broader muscle.
Why are Pennate muscles stronger than parallel?
The fibers of these muscles are shorter and are situated at an angle to the long axis of the muscle. Thus, if two muscles were of equal cross-sectional area, a pennate muscle would be stronger than a parallel fibered one because of its larger physiological cross-sectional area.
What are the two major categories of muscle fiber arrangements?
94 Cards in this Set
| The two major types of fiber arrangements that essentially all skeletal muscles may be grouped into are: | parallel and pennate |
|---|---|
| Thin and broad muscles, originating from broad, fibrous, sheet-like aponeuroses are known as: | flat |
How are parallel muscles characterized in skeletal muscles?
Parallel muscles are characterized by fascicles that run parallel to one another, and contraction of these muscle groups acts as an extension of the contraction of a single muscle fiber.
What is the definition of a parallel system?
• Definition: A parallel system consists of an algorithm and the parallel architecture that the algorithm is implemented. • Note that an algorithm may have different performance on different parallel architecture. • For example, an algorithm may perform differently on a linear array of processors and on a hypercube of processors.
How are pennate muscles different from parallel muscles?
In Pennate muscles, the tendon runs through the length of the muscle. Fascicles pull on the tendon at an angle, thus not moving as far at the parallel muscles during a contraction. However, these muscles tend to have relatively more muscle fibers than similarly sized parallel muscles, and thus carry more tension.
What is the difference between parallel and multithreaded programming?
Parallel programming is a broad concept. It can describe many types of processes running on the same machine or on different machines. Multithreading specifically refers to the concurrent execution of more than one sequential set (thread) of instructions. Multithreaded programming is programming multiple, concurrent execution threads.
