Type IIa Red fibers. Fast oxidative (also called fast twitch A or fatigue resistant fibers). Contain:
- Large amounts of myoglobin.
- Many mitochondria.
- Many blood capillaries.
- High capacity for generating ATP by oxidation. Split ATP at a very rapid rate and, hence, high *contraction velocity
- Resistant to fatigue but not as much as slow oxidative fibers.
- Needed for sports such as middle distance running and swimming.
Type IIb White. Fast glycolytic (also called fast twitch B or fatigable fibers). Contain:
- Low myoglobin content.
- Few mitochondria.
- Few blood capillaries.
- Large amount of glycogen.
- Split ATP very quickly.
- Fatigue easily.
- Needed for sports like sprinting.
Hope it is useful to you!

What are blended fibres?
Blended fibres is mixing 2 or more fibres to achieve the best fibres in the yarn.

What are the functional differences between a motor neuron and a sensory neuron?
most nerves carry 2 types of fibre 'sensory 'or 'afferent 'fibres bring messages from receptors in the sense organs and other structures to the spinal cord and brain. 'motor'or 'efferent' fibres convey signals from the brain or spinal cord to a muscle or gland. some nerves contain just sensory fibres e.g.optic nerve whilst others have just motor fibres.
What is the H zone A band?
Within skeletal muscle there are muscle fibres... and within muscle fibres there are myofibrils... and within a myofibril there is a sarcomere.Within the sarcomere there are 2 types of bands:-Actin (light)-Myosin (dark)There are different striations of these bands, this is what makes up the muscle fibre:The A band is where actin & myosin overlapp- it contains both myosin & actinThe I band only contains actinThe H zone only contains myosinThe Z line is in the centre of each I band, and marks the start of a sarcomere
How to distinguish internal organs from skeletal muscle?
- Most skeletal muscles are attached to bones by bundles of collagen fibres known as tendons. 2) Smooth muscle: Smooth muscle generally forms the supporting tissue of blood vessels and hollow internal organs, such as the stomach, intestine, and bladder.
What type of muscle fibers are there?
You have three types of muscle fibers. 1) Skeletal muscle fibers. 2) Cardiac muscle fibers. 3) Smooth muscle fibers.
Why are arteries organs but capillaries not?
organ is a structure made up of 2 or more no. of tissues(group of similar cells structurally and functionally)....artery is made up of endothelial cells, muscle fibres, elastic fibres etc placed in layers...hence is an organ. whereas capillaries only have endothelial cells.
Where clothing fibers come from?
mostly Cambodia
