(n.) The head; also, a knoblike protuberance or capitulum.
(n.) The top or superior part of a thing.
(n.) The council or ruling body of the University of Cambridge prior to the constitution of 1856.
Example Sentences:
(1) The nuclei were isolated from boar spermatid or sperm cells at three distinct stages of spermatogenesis: just before the completion of a maturation process in the testis (late spermatid), immediately after a subsequent transformation into spermatozoa (caput spermatozoon), and after full maturation (cauda spermatozoon).
(2) Rat spermatozoa were recovered from the caput, corpus, and cauda epididymides and assayed for glycosidase activity, total nonamino (neutral) carbohydrate, and protein content.
(3) Flagellar movement of golden hamster spermatozoa obtained from the testis and the caput and cauda epididymides was observed by a light microscope while holding them at their heads with a micropipette.
(4) Results indicate that sperm first exhibit WGA reactivity on their flagellae in the region of the distal caput, and that the appearance of WGA receptors is due to the binding of a 54-Kd glycoprotein (SMA4) to the cell surface.
(5) There were no changes in SGP-2 mRNA concentrations in the initial segment and caput epididymidis.
