Skeletal muscle is made up of individual muscle cells or myocytes, known as muscle fibers. They are formed from the fusion of developmental myoblasts (a type of embryonic progenitor cell that gives rise to a muscle cell) in a process known as myogenesis.Muscle fibres are cylindrical, and multinucleated.keletal muscle is a form of striated muscle tissue which is under the voluntary control of the somatic nervous system. It is one of three major muscle types, the others being cardiac muscle and smooth muscle.
Parakeets lay their eggs over a 9-16 day period depending how many eggs they produce as they can only lay one eggs every 2-3 days. It takes parakeets 18-21 days for the eggs to hatch.
First time egg layers may take up to a week to lay their first clutch. Figure out the time since they were bred, and she could lay her eggs any time from two weeks to four weeks after breeding, most of the time it is about 3 weeks on the dot.
