What else can I help you with?
A muscle in which the fibers are arranged at an angle to a central longitudinal tendon has a arrangement?
This type of muscle arrangement is called pennate. Pennate muscles maximize the number of muscle fibers in a given space, allowing for greater force production. Examples of pennate muscles include the deltoid and gastrocnemius.
What is the muscle fiber arrangement in a pennate muscle?
short fibers, arranged obliquely to their tendons
What muscle arrangement fibers run tangentially or feather?
The Pennate arrangement. The fascicles attach obliquely to the tendon.
What muscle is named for the arrangement of its fascicles?
The muscle named for the arrangement of its fascicles is the "pennate" muscle. In pennate muscles, the fascicles are arranged obliquely to the tendon, resembling a feather's structure. This arrangement allows for greater force production due to the increased number of muscle fibers that can fit into a given area, making pennate muscles efficient for generating power. Examples include the deltoid and the rectus femoris.
Describe fascicle arrangement in a pennate muscle?
The fascicles are short and attach obliquely to a central tendon that runs the length of a muscle.
Describe the differences between a fusiform and pennate muscle?
In non pennate or fusiform structure, fibers run in line with the line of pull. There is a longer fiber length associated with a fusiform structure, but often not a very thick cross-section -Weaker overall, but greater ROM (range of movement) making it good for speed In a pennate or penniform muscle structure, there is an oblique fiber pattern. Fibers do not pull in the same direction as the line of muscle pull. There is a shorter fiber length but usually a thicker cross sectional area. -There are three pennate types 1) Unipennate: One-sided feather such as in the semimembranous 2) Bipennate: Two-sided feather such as in the gastrocnemius 3) Multipennate: many-headed two sided feather such as in the deltoids -Good for strength, smaller ROM, meaning it is not as great for speed
Which type of fiber arrangement characterizes the sphincter muscles?
Circular/Oval
What is it about the arrangement of muscles tha suit them for their jobs?
The arrangement of muscles is optimized for their specific functions, allowing for efficient movement and force generation. Muscles are structured in various ways, such as parallel, circular, or pennate, which influence their strength and range of motion. For example, pennate muscles can pack more fibers into a given area, providing greater force, while parallel muscles allow for greater elongation and speed. Additionally, the orientation of muscle fibers aligns with the direction of movement, enhancing overall performance and coordination.
