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.
Relevance. Rating Newest Oldest. Best Answer: The eggs take roughly 19-21 days to hatch after being laid, and a female will lay an egg every 24-48 hours. Please be aware that same sex birds will perform copulatory behaviour and that not all mating leads to the laying of fertile eggs. Females will lay unfertilised eggs, even with the absence of males.
