A coral septum is one of the radial calcareous plates in the corallites of a coral. [18]Annelids have septa that divide their coelom into segmented chambers. [19]Many shelled organisms have septa subdividing their shell chamber, including rhizopods, cephalopods and gastropods, the latter seemingly serving as a defence against shell-boring predators.
In addition to having septate basidia, heterobasidiomycetes also frequently possess large irregularly shaped sterigmata and spores that are capable of self-replication – a process where a spore, instead of germinating into a vegetative hypha, gives rise to a sterigma and a new spore, which is then discharged as if from a normal basidium.
Aseptate (non-septate) or coenocytic (without septa) Non-septate hyphae are associated with Mucor , [ 9 ] some zygomycetes , and other fungi. Pseudohyphae are distinguished from true hyphae by their method of growth, relative frailty and lack of cytoplasmic connection between the cells.
Septate junctions are in a tight arrangement which is parallel to each other. [4] For the septate junctions, several components are related to the function or the morphology of septate junctions, like Band 4.1-Coracle, Discs-large, fasciclin III, Neurexin IV (NRX) and so on. [5] [6] Band 4.1-Coracle is necessary for the interaction of the cell. [6]
Cutaway of a nautilus shell showing the chambers. Septa (singular septum) are thin walls or partitions between the internal chambers of the shell of a cephalopod, namely nautiloids or ammonoids.
Anatomy is often described in planes, referring to two-dimensional sections of the body. A section is a two-dimensional surface of a three-dimensional structure that has been cut. A plane is an imaginary two-dimensional surface that passes through the body.
Surface anatomy, or superficial anatomy, is important in human anatomy being the study of anatomical landmarks that can be readily identified from the contours or other reference points on the surface of the body. [1] With knowledge of superficial anatomy, physicians gauge the position and anatomy of deeper structures.
Other forms of uterine malformation need to be considered in the work-up for uterine septum. An arcuate uterus contains a residual cranial septum that is smaller than an incomplete septum but definitions between the two conditions are not standardized, - a cause for discrepancies in the literature. A bicornuate uterus is sometimes confused with ...
