Comparison Human and Chick Neural Endings Timeline
Striped muscle and tendon Sensory nerve endings Motor nerve endings Human (approximate age) weeks Chick (Tello) (approximate age) days
Beginning differentiation 7 5
Myofibrils appear Exploratory fibres with bulbous endings penetrate into muscles 8 6
Great increase of connective tissue. Vast numbers of nuclei - - - 6-7
Isolated “fat” fibres - 10-12 7
Varicose endings in contact with myotubes - 10
Tendon fibres diflerentiate 12 10
Beginning pacinian corpuscle 20 11
Multiplication of myotubes - 12-22 9-13
Spindles differentiate - 20 12
Dissociation of myotubes from one another. Nuclei become peripheral Spindles become complex 22-26 13
pacinian corpuscle well developed 26-28 15
Plates begin to differentiate 26-28 (very rudimentary except tongue) 18
