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.
Lovebirds reach maturity between six months to a year and are then ready to mate. Lovebirds begin to lay eggs five to 12 days after mating, usually one egg every other day. The size of the clutch is generally between three to seven eggs. Incubation time is about 23 days for each egg. Female lovebirds also lay eggs when there is no access to a male lovebird, although these are not fertile eggs. Separation from other birds curbs excess egg laying.
