**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 bodies	—	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 bodies well developed	—	26-28	15
		Plates begin to differentiate	26-28 (very rudimentary except tongue)	18
