It is an extension of the pars distalis up and around infundibulum. The wall of the infundibulum is smooth. Sequential muscle contraction of the infundibulum and acetabulum causes attachment and detachment. There is also either a second infundibulum or a cementum-filled furrow. They hope to escape E1 with their people using the jumpgun and the Infundibulum. The sequential muscle contraction the infundibulum and acetabulum causes attachment and detachment. This space continues laterally as a three-dimensional slit-like space - the ethmoidal infundibulum. They also mentioned the presence of a furrow and infundibulum as shared traits. Defects in infundibulum development can result in a heart condition known as tetrology of Fallot. When he entered the chrono-synclastic infundibulum, Rumfoord became aware of the past and future. The infundibulum is also known as the "dental cup". An infundibulum (Latin for "funnel"; plural, "infundibula") is a funnel-shaped cavity or organ. Over much of its range it co-exists with another species of comb jelly, "Bolinopsis infundibulum". With the other configurations, the sinus will drain, firstly, into the infundibulum. The infundibulum of a tooth is the funnel-like center that is filled with "cementum".
