A structure that lies outside the plasma membrane and surrounds the entire cell.

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

Everything external to, but not including, the cytoplasmic membrane of bacteria, encompassing the periplasmic space, cell wall, and outer membrane if present.

tracheal system development (sensu Insecta)

The process whose specific outcome is the progression of the tracheal system over time, from its formation to the mature structure. The traceal system is the respiratory system, a branched network of epithelial tubes that supplies oxygen to target tissues. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

Complex formed in muscle cells between the membrane of the sarcoplasmic reticulum and invaginations of the plasma membrane (T-tubules).

tracheal epithelial cell fate determination (sensu Insecta)

tracheal cell fate determination (sensu Insecta)

Process by which a cell becomes capable of differentiating autonomously into a tracheal cell regardless of its environment; upon determination, the cell fate cannot be reversed. Tracheal cells are set aside as 10 clusters of approximately 80 cells on each side of the embryo (termed tracheal placodes). As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

Invagination of the plasma membrane of a muscle cell that extends inward from the cell surface around each myofibril. The ends of T-tubules make contact with the sarcoplasmic reticulum membrane.

The projection of tracheal branches of the respiratory system towards their target tissues. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).

The process whereby a relatively unspecialized monocyte acquires the specialized features of a osteoclast cell.

tracheal epithelial cell migration (sensu Insecta)

The orderly movement of tracheal cells during development of the tracheal system. As in, but not restricted to, the true insects (Insecta, ncbi_taxonomy_id:50557).
