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.
The fertilized ova takes approximately 4 hours to travel to the uterus. Once in the uterus, calcification of the egg's shell takes approximately 20 hours. This is why a hen can only lay one egg per 24 hour period. About 15 minutes after the first egg is laid, the hen ovulates again and the process is repeated.
