1) A usually translucent somewhat elastic tissue that composes most of the skeleton of vertebrate embryos and except for a small number of structures (as some joints, respiratory passages, and the external ear) is replaced by bone during ossification in the higher vertebrates.
2) A part or structure composed of cartilage.
3) A tough, flexible tissue that lines joints and gives structure to the nose, ears, larynx, and other parts of the body.

1) A usually tubular enclosed passage.
2) A passage created in a selectively permeable membrane by a conformational change in membrane proteins.
3) A protein or cluster of proteins that functions as a channel.

1) A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
2) A small cavity or space in the tissues of an organism containing air or fluid.
3) A cavity or vesicle in the cytoplasm of a cell containing fluid.

1) A villous structure of tangled masses of blood vessels contained within the third, lateral, and fourth ventricles of the BRAIN. It regulates part of the production and composition of cerebrospinal fluid.
2) A highly vascular portion of the pia mater that projects into the ventricles of the brain and is thought to secrete the cerebrospinal fluid.
