The directed, self-propelled movement of cilia of epithelial cells. Depending on the type of cell, there may be one or many cilia per cell. This movement is usually coordinated between many epithelial cells, and serves to move extracellular fluid.

The establishment of an organism's body plan or part of an organism with respect to the left and right halves. The pattern can either be symmetric, such that the halves are mirror images, or asymmetric where the pattern deviates from this symmetry.

The progression of a cardiac septum over time, from its initial formation to the mature structure.

The directed, self-propelled movement of a cilium.

The directed, self-propelled movement of a cilium.

Any process that modulates the frequency of cilium movement, the directed, self-propelled movement of a cilium.

The establishment of an organism's body plan or part of an organism with respect to the left and right halves. The pattern can either be symmetric, such that the halves are mirror images, or asymmetric where the pattern deviates from this symmetry.

The process whose specific outcome is the progression of the heart over time, from its formation to the mature structure. The heart is a hollow, muscular organ, which, by contracting rhythmically, keeps up the circulation of the blood.

The series of events required for an organism to receive an auditory stimulus, convert it to a molecular signal, and recognize and characterize the signal. Sonic stimuli are detected in the form of vibrations and are processed to form a sound.

The acquisition and processing of information and/or the storage and retrieval of this information over time.

Any process involved in the controlled movement of a flagellated sperm cell.

The establishment of the nervous system with respect to the left and right halves.

The movement of cilia of epithelial cells of the Left Right Organizer (LRO), also referred to as the node in mouse or the Kupffer's vesicle in zebrafish, resulting in the leftward fluid flow across the LRO and generation or transport of a signal which determines asymmetry in an organism's body plan with respect to the left and right halves.

The process in which the anatomical structure of a cardiac septum is generated and organized. A cardiac septum is a partition that separates parts of the heart.

Determination of the asymmetric location of the heart with respect to the left and right halves of the organism.

The directed, self-propelled movement of a cilium (aka flagellum) that contributes to the movement of a flagellated sperm.

Any process that modulates the frequency of cilium movement, the directed, self-propelled movement of a cilium.

Any process involved in the controlled movement of a flagellated sperm cell.

A motile cilium where the axoneme has a ring of nine outer microtubule doublets plus two central microtubules (and is therefore called a 9+2 axoneme).

The portion of the axoneme that is close to the base of the cilium.

A dynein complex found in eukaryotic cilia and flagella; the motor domain heads interact with adjacent microtubules to generate a sliding force which is converted to a bending motion.

The bundle of microtubules and associated proteins that forms the core of cilia (also called flagella) in eukaryotic cells and is responsible for their movements.

A cilium which may have a variable arrangement of axonemal microtubules and also contains molecular motors. It may beat with a whip-like pattern that promotes cell motility or transport of fluids and other cells across a cell surface, such as on epithelial cells that line the lumenal ducts of various tissues; or they may display a distinct twirling motion that directs fluid flow asymmetrically across the cellular surface to affect asymmetric body plan organization. Motile cilia can be found in single as well as multiple copies per cell.

Outer arm structure present on the outer doublet microtubules of ciliary and flagellar axonemes. Outer dynein arms contain 2-3 heavy chains, two or more intermediate chains and a cluster of 4-8 light chains. Inner and outer dynein arms have different functions in the generation of microtubule-based motility.

A motile cilium where the axoneme has a ring of nine outer microtubule doublets but no central microtubules (and is therefore called a 9+0 axoneme).

A motile cilium where the axoneme has a ring of nine outer microtubule doublets plus two central microtubules (and is therefore called a 9+2 axoneme).

The portion of the axoneme that is close to the base of the cilium.
