Answer: SKELETAL MUSCLE
Explanation:
Skeletal muscles is a type of muscle tissue that forms those muscles that move the bones of the skeleton,straited because straitations (strips) can be seen on microscopic examination and involuntary as it is under conscious control.
Although most skeletal muscles move bones,they also accomodate a degree of voluntary control in breathing.
A lot of movements can be finely coordinated.example; writing but may also be controlled subconsciously, maintaining an upright position does not normally require thoughts unless a new locomotor skill is being learned example skating or cycling and the diaphram maintains breathing while asleep.
The fibre (cells) of the skeletal muscle are cylindrical,contain several nuclei and can be up to 35cm long.
Skeletal muscle contraction is stimulated by motor nerve impulses originating in the brain or spinal cord and ending in the neuromuscular junction.
The contraction of a whole skeletal muscle occurs because of coordinated contraction of it's individual fibres.
Your answer is B biological catalyst that regulates chemical reaction in the body
The statement above is TRUE.
The osteon is the fundamental functional unit of a compact bone. Osteons are roughly cylindrical in shape and they are typically several millimetre long and about 0.2mm in diameter. The osteon resembles the growth ring of a tree trunk.
The cylindrical structure of osteon is made up of four different parts which are a central tube, a lamellae, a lacunae and canaliculi.
