The process, occurring in the embryo, by which the anatomical structures of the pectoral fin are generated and organized. Morphogenesis pertains to the creation of form. Pectoral fins are bilaterally paired fins mounted lateraly and located behind the gill covers of fish. These fins are used for lateral mobility and propulsion.

The process by which the anatomical structures of the arm are generated and organized. Morphogenesis pertains to the creation of form. In humans, the arms are the two upper limbs of the body from the shoulder to the hand.

The process by which the anatomical structures of the medial fin are generated and organized. Morphogenesis pertains to the creation of form. A medial fin is an unpaired fin of fish, usually located dorsomedially or ventromedially and primarily used for stability while swimming.

The process by which the anatomical structures of the dorsal fin are generated and organized. Morphogenesis pertains to the creation of form. A dorsal fin is an unpaired medial fin on the dorsal aspect of fish that provides lateral stability while swimming. Generally fish have one or two dorsal fins.

The process by which the anatomical structures of the caudal fin are generated and organized. Morphogenesis pertains to the creation of form. A caudal fin is an unpaired medial fin mounted at the caudal end of the fish, and is the main fin used for propulsion.

Catalysis of the reaction: Ca2+(in) + Na+(out) = Ca2+(out) + Na+(in).

A multi-subunit complex deposited by the spliceosome upstream of messenger RNA exon-exon junctions. The exon-exon junction complex provides a binding platform for factors involved in mRNA export and nonsense-mediated mRNA decay.

The joining of specific branches of a tubular system to form a continuous network.

Fusing of specific tracheal branches to branches from neighboring hemisegments to form a continuous tracheal network. Branch fusion is mediated by individual cells at the tip of each branch, which contact a similar cell and undergo a coordinated series of morphogenetic events that create a bicellular fusion joint.
