Abstract
THE role of the avian oviduct in egg formation has received attention for many years. More recently, the oviduct’s role in the storage and transport of sperm cells has been investigated (see reviews by Hafez, 1968; and Van Teinhoven, 1968). While the spontaneous motility of the oviduct is necessary for both the transport of ovum and of spermatozoa, there has been a minimum of work in the area of oviduct motility.The spontaneous motility pattern of avian vaginal and uterine muscle strips was studied in vitro by Sykes (1955). He demonstrated that contractions of the vagina differed from those of the uterus, being of smaller amplitude and greater frequency. No spontaneous motility was found in the vagina of a non-laying hen and the amplitude of uterine contractions was much lower than those of a laying hen. Sykes was unable to demonstrate differences between regions within the same part of the…
