The characteristic movement of cells from the dorsal ridge of the neural tube to a variety of locations in a vertebrate embryo.

The process in which the anatomical structures of the trabecular cardiac ventricle muscle are generated and organized.

The process whose specific outcome is the progression of the peripheral nervous system over time, from its formation to the mature structure. The peripheral nervous system is one of the two major divisions of the nervous system. Nerves in the PNS connect the central nervous system (CNS) with sensory organs, other organs, muscles, blood vessels and glands.

The process of creating a trabecula in the heart. A trabecula is a tissue element in the form of a small beam, strut or rod.

The process whose specific outcome is the progression of the skin epidermis over time, from its formation to the mature structure.

An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain an additional tiers: the upstream MAP4K. The kinases in each tier phosphorylate and activate the kinase in the downstream tier to transmit a signal within a cell.

The cellular process in which a signal is conveyed to trigger a change in the activity or state of a cell. Signal transduction begins with reception of a signal (e.g. a ligand binding to a receptor or receptor activation by a stimulus such as light), or for signal transduction in the absence of ligand, signal-withdrawal or the activity of a constitutively active receptor. Signal transduction ends with regulation of a downstream cellular process, e.g. regulation of transcription or regulation of a metabolic process. Signal transduction covers signaling from receptors located on the surface of the cell and signaling via molecules located within the cell. For signaling between cells, signal transduction is restricted to events at and within the receiving cell.

A series of molecular signals initiated by binding of a ligand to the tyrosine kinase receptor EGFR (ERBB1) on the surface of a cell. The pathway ends with regulation of a downstream cellular process, e.g. transcription.

A series of molecular signals initiated by binding of a ligand to the tyrosine kinase receptor EGFR (ERBB1) on the surface of a cell. The pathway ends with regulation of a downstream cellular process, e.g. transcription.

A series of molecular signals initiated by binding of a ligand to a member of the ERBB family of receptors on the surface of a cell, where the signal is transmitted by ERBB2. The pathway ends with regulation of a downstream cellular process, e.g. transcription. ERBB2 receptors are themselves unable to bind to ligands, but act as a signal-amplifying tyrosine kinase within a heterodimeric pair.

Any process that activates or increases the frequency, rate or extent of protein kinase B signaling, a series of reactions mediated by the intracellular serine/threonine kinase protein kinase B.

Any process that modulates the frequency, rate or extent of synapse assembly, the aggregation, arrangement and bonding together of a set of components to form a synapse.

Any process that modulates the frequency, rate or extent of synapse assembly, the aggregation, arrangement and bonding together of a set of components to form a synapse.

Any process that modulates the frequency, rate or extent of synapse assembly, the aggregation, arrangement and bonding together of a set of components to form a synapse.

Any process that modulates the extent of synapse maturation, the process that organizes a synapse so that it attains its fully functional state.

Any process that modulates the extent of synapse maturation, the process that organizes a synapse so that it attains its fully functional state.

Any process that modulates the extent of synapse maturation, the process that organizes a synapse so that it attains its fully functional state.

Any process that modulates the frequency, rate or extent of cell motility.

The space external to the outermost structure of a cell. For cells without external protective or external encapsulating structures this refers to space outside of the plasma membrane. This term covers the host cell environment outside an intracellular parasite.
