What are the 3 parts of the trapezius?
The trapezius muscle has three parts: the upper fibers (descending from the skull to the upper back), the middle fibers (running horizontally across the upper back), and the lower fibers (ascending from the middle back to the shoulder blades).
How are slow oxidative fibers in skeletal muscle used during physical activity?
Slow oxidative fibers in skeletal muscle are used during physical activity to provide sustained energy for endurance activities, such as long-distance running or cycling. These fibers are efficient at using oxygen to produce energy through aerobic metabolism, allowing for prolonged muscle contractions without fatigue.
Name the 3 types of fibers in areolar connective tissue?
the three basic types of fibers that are found in connective tissue are collagen fibers, elastic fibers, and reticular fibers
Slow twitch muscle fibers are resistant to what?
Slow twitch muscle fibers are resistant to fatigue because they have a high capacity for aerobic energy production due to their abundant mitochondria and myoglobin content. This enables them to sustain prolonged, low-intensity activities like endurance running or cycling.
Collagen fibers which run from the fibrous bone covering into the bone itself are called?
Sharpey's Fibers
Fibers that are straight and look like strong cables?
There are two types of fibers that are straight and look like strong cables. One of them is elastic fibers. The second is collagen fibers.
Which muscle fibers are best suited for running a marathon?
Type I (red) muscle fibers, which have slow oxidative characteristics, are those primarily called on for long-distance running. These are more commonly referred to as 'slow-twitch' muscle fibers.
Why does paper tear easily straight but not across?
Due to the way paper is made, its fibers tend to run in one direction. If you tear in that direction, along the fibers, the paper tears easily, and the fibers guide the tear to be straight across. If you tear the paper across the fibers, all of the above is untrue.
Activities such as swimming and running are most likely to stimulate development of what type of muscle fibers?
Slow, fatigue-resistant fibers
What muscle fibers are best suited for running a marathon?
The muscle fibers best suited for running a marathon are slow-twitch muscle fibers, also known as Type I fibers. These fibers are highly resistant to fatigue and are efficient at using oxygen to generate energy for prolonged, endurance activities. They have a rich supply of blood vessels and mitochondria, enabling sustained aerobic metabolism, which is essential for long-distance running. In contrast, fast-twitch fibers (Type II) are more suited for short bursts of strength and speed.
What is a complicated network of protein fibers running through a cell?
chromosomes
Is cotton an adverb?
No, it's a common noun, or an adjective describing things made from cotton. It is also a colloquial verb, meaning to accept or approve, normally used in the negative. This is from an archaic use of cotton to mean 'go together' or fit well, as do the fibers in cotton thread. e.g. We don't cotton to people telling us what to do.
What is the complicated network of protein fibers running through a cell?
the bread crums are what is important
What abdominal muscle has fibers running at right angle sto the internal abdominal obliques?
Aponeurosis
What neuron fibers are running through the CNS?
In the central nervous system (CNS), there are two main types of neuron fibers: afferent (sensory) fibers that carry information from sensory receptors to the CNS, and efferent (motor) fibers that carry information from the CNS to effectors such as muscles and glands. These fibers make up the vast network of connections that allow for communication within the brain and spinal cord.
What are the 3 parts of the trapezius?
The trapezius muscle has three parts: the upper fibers (descending from the skull to the upper back), the middle fibers (running horizontally across the upper back), and the lower fibers (ascending from the middle back to the shoulder blades).
What is the function of the muscle fibers?
Muscle fibers contract to generate force and produce movement in the body. They are responsible for actions such as lifting objects, running, and even maintaining posture. Additionally, muscle fibers play a vital role in regulating body temperature and supporting various bodily functions.
