The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

Long distance growth of a single axon process involved in cellular development.

The series of events required for an organism to receive a touch stimulus, convert it to a molecular signal, and recognize and characterize the signal. This is a neurological process. The perception of touch in animals is mediated by mechanoreceptors in the skin and mucous membranes and is the sense by which contact with objects gives evidence as to certain of their qualities. Different types of touch can be perceived (for example, light, coarse, pressure and tickling) and the stimulus may be external or internal (e.g. the feeling of a full stomach).

The neurite development process that generates a long process of a neuron, as it invades a target tissue.

The chemotaxis process that directs the migration of an axon growth cone to a specific target site in response to a combination of attractive and repulsive cues.

Determination of where the salivary gland forms, the total number of salivary gland cells and how many cells are allocated to each of the specialised cell types within the salivary gland.

The process in which the migration of an axon growth cone of a motor neuron is directed to a specific target site in response to a combination of attractive and repulsive cues.

The orderly movement of a glial cell, non-neuronal cells that provide support and nutrition, maintain homeostasis, form myelin, and participate in signal transmission in the nervous system.

A process that is carried out at the cellular level which results in the assembly, arrangement of constituent parts, or disassembly of an extracellular matrix.

Any process that activates or increases the frequency, rate or extent of cell migration.

The process, occurring in the embryo, by which the anatomical structures of the medial fin are generated and organized. Medial fins are unpaired fins of fish, usually located dorsomedially or ventromedially and primarily used for stability while swimming.

The process in which the anatomical structures of the skin are generated and organized. The skin is the external membranous integument of an animal. In vertebrates the skin generally consists of two layers, an outer nonsensitive and nonvascular epidermis (cuticle or skarfskin) composed of cells which are constantly growing and multiplying in the deeper, and being thrown off in the superficial layers, as well as an inner, sensitive and vascular dermis (cutis, corium or true skin) composed mostly of connective tissue.

Long distance growth of a single axon process involved in cellular development.

The orderly movement of a mesenchymal cell from one site to another, often during the development of a multicellular organism.

The process whose specific outcome is the progression of the embryo over time, from zygote formation through syncytial blastoderm to the hatching of the first instar larva. An example of this process is found in Drosophila melanogaster.

The process in which the migration of an axon growth cone of a retinal ganglion cell (RGC) is directed to its target in the brain in response to a combination of attractive and repulsive cues.

The behavior of an organism in response to an odor.

The process whose specific outcome is the progression of the central complex over time, from its formation to the mature structure. The central complex region of the insect brain is thought to be crucial for control of locomotive behavior. Located in the middle of the two protocerebral hemispheres, it comprises four neuropilar regions, the fan-shaped body, the ellipsoid body, the protocerebral bridge and the paired noduli.

The series of events involved in visual perception in which a light stimulus is received and converted into a molecular signal.

The chemotaxis process that directs the migration of a photoreceptor cell axon growth cone to its target in the optic lobe in response to a combination of attractive and repulsive cues.

The process in which the migration of a neuron projection is directed to a specific target site in response to a combination of attractive and repulsive cues.

The process in which the migration of a neuron projection is directed to a specific target site in response to a combination of attractive and repulsive cues.

Long distance growth of a single neuron projection involved in cellular development. A neuron projection is a prolongation or process extending from a nerve cell, e.g. an axon or dendrite.

Long distance growth of a single neuron projection involved in cellular development. A neuron projection is a prolongation or process extending from a nerve cell, e.g. an axon or dendrite.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

The component of a membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The long process of a neuron that conducts nerve impulses, usually away from the cell body to the terminals and varicosities, which are sites of storage and release of neurotransmitter.

The migrating motile tip of a growing neuron projection, where actin accumulates, and the actin cytoskeleton is the most dynamic.
